In modern times, hand held devices and laptop computers have turned those science fiction ideas into everyday realities, as people can tell their phones to call their mom, to provide the outdoor temperature or to help them recall the name of a movie they saw decades ago.

These helpful technological devices, however, may some day go the way of the clunky desktop computers of yesteryear, as scientists around the world work to turn the vision of a quantum computer into a reality.

Scientists hope to develop a next generation of quantum computer that is faster, smarter, more flexible and more energy-efficient than current technological devices. They hope these devices could be the key to future technological breakthroughs, inspiring them to figure out how to bring the theory to life.

Collaborating with scientists at Ames Laboratory in Iowa, Qiang Li, SUNY Empire Innovation Professor in the Department of Physics and Astronomy at Stony Brook University and Leader of the Advanced Energy Materials Group at Brookhaven National Laboratory, recently published a study in the journal Nature Materials that provided fundamental information that might contribute to the field of quantum computers.

The group of scientists, which included Li’s PhD student Pedro Lozano, discovered a light-induced switch that twists the crystal lattice of a semimetal, turning on an electron current that the team believes is nearly dissipationless.

When currents move through wires between utilities and people’s homes and offices, that current encounters resistance, losing energy along the way, as if the movement towards the home created a tax on the journey. Similarly, dissipation inside an electronic device can sap some of the energy needed to transmit information or a signal, reducing the effectiveness of the process.

Li and BNL physicist Genda Gu synthesized, patterned and characterized the material at BNL, while Jigang Wang, a senior scientist at Ames Laboratory, performed the light-induced lattice twisting. The team helped create the light-induced switch.

Li described the effort as “fundamental research” and cautioned that any such advancement is more of a principal study, rather than a step closer to making any new qubit (the basic unit of quantum information) device.

“This is an experimental study to show that this is possible,” Li said. “It’s a demonstration of feasibility that you can harness chirality for building quantum information systems.”

With chirality, electrons have a handedness based on whether their spin and momentum are aligning in the same or opposite direction.

Once electrons have chirality, they can travel much easier, enabling a more direct and predictable route from one place to another.

Scientists like Li would like to create physical systems that enable them to control the chirality, preventing the spin from switching from one direction to the other.

Numerous factors can disrupt the chirality of an electron, including imperfections in the material.

A pulse-triggered light-induced switch can change the topology of a Weyl semimetal, making it possible to enable the movement of electrons that are nearly dissipationless. “For pure electronics, even computer chips, electrons consume a lot of energy because of electrical resistance,” Li said. “A chiral current [however] will travel without resistance, in ideal cases without chirality flipping.”

Chiral electrons travel through the semimetal at a speed as high as 1/300th of the speed of light and can travel considerably further before a collision that alters its direction, speed, or other particle properties. The mean free path, which is the average distance a particle will travel between such disruptive events, for a typical metal is nanometers. By contrast the chiral electrons can move micrometers, which is thousands of times longer.

An unperturbed chiral electron could travel further distances over shorter intervals, carrying preserved coded information without losing much energy during movement. 

Scientists have sought ways to create a path through which electrons travel with this predictable spin. They can break chiral symmetry by applying a magnetic field, which led to the discovery of the chiral magnetic effect by a team of scientists from BNL and Stony Brook University, including Dmitri Kharzeev, in 2014.  

For this work, Li received the Brookhaven Science and Technology Award in 2019.

“Using a magnetic field is problematic for some computations,” he said. Besides, people don’t want a “big magnet around your computers.”

Another way is to send in the laser pulse, creating left-handed or right-handed polarization.

To determine the ideal pulse to change the material, Li and Wang partnered with several theorists from Ames Lab and Ilias Perakis, Professor and Chair of Physics at the University of Alabama — Birmingham.

The theorists conducted detailed analysis of the lattice vibrations and the ideal pulse energy needed to break symmetry in the Weyl semimetal. “There is a very strong collaboration between the theorists and the experimentalists,” Li said.

While the research remains fundamental and is unlikely to generate a specific product any time soon, Li said it has “attracted a lot of attention” from other scientists and is a significant step forward in establishing the basic principles for topology-enabled quantum logic and information systems.

Li and Wang have been collaborating on this project for about two years as scientists around the world are in a “horse race” to produce results in the arena of quantum computing.

A resident of Setauket, Li and his wife Meiling Shih, have two children. Shih, who worked in the Stony Brook Pharmacological Science Department and later at Morgan Stanley, is retired and is now a volunteer instructor of a Tai Chi class for local seniors, 

Li enjoys jogging and runs a few miles every other day.

Down the road, Li hopes to address how to make the two quantum bits talk to each other.

Results from a study of clouds and aerosols conducted in the Azores revealed that new particles can seed the formation of clouds in the marine boundary layer—the atmosphere up to about a kilometer above Earth's surface—even over the open ocean, where the concentration of precursor gases was expected to be low.

Understanding previously undocumented source of new particle formation will improve models of aerosols, clouds, and their impact on Earth’s climate

New results from an atmospheric study over the Eastern North Atlantic reveal that tiny aerosol particles that seed the formation of clouds can form out of next to nothingness over the open ocean. This “new particle formation” occurs when sunlight reacts with molecules of trace gases in the marine boundary layer, the atmosphere within about the first kilometer above Earth’s surface. The findings, published in the journal Nature Communications, will improve how aerosols and clouds are represented in models that describe Earth’s climate so scientists can understand how the particles—and the processes that control them—might have affected the planet’s past and present, and make better predictions about the future.

“When we say ‘new particle formation,’ we’re talking about individual gas molecules, sometimes just a few atoms in size, reacting with sunlight,” said study co-author Chongai Kuang, a member of the Environmental and Climate Sciences Department at the U.S. Department of Energy’s Brookhaven National Laboratory. “It’s interesting to think about how something of that scale can have such an impact on our climate—on how much energy gets reflected or trapped in our atmosphere,” he said.

Using an aircraft outfitted with 55 atmospheric instrument systems, scientists traversed horizontal tracks above and through clouds and spiraled down through atmospheric layers to provide detailed measurements of aerosols and cloud properties. The aircraft data were supplemented by measurements made by ground-based radars and other instruments.

But modeling the details of how aerosol particles form and grow, and how water molecules condense on them to become cloud droplets and clouds, while taking into consideration how different aerosol properties (e.g., their size, number, and spatial distribution) affect those processes is extremely complex—especially if you don’t know where all the aerosols are coming from. So a team of scientists from Brookhaven and collaborators in atmospheric research around the world set out to collect data in a relatively pristine ocean environment. In that setting, they expected the concentration of trace gases to be low and the formation of clouds to be particularly sensitive to aerosol properties—an ideal “laboratory” for disentangling the complex interactions.

“This was an experiment that really leveraged broad and collaborative expertise at Brookhaven in aerosol observations and cloud observations,” Kuang said. Three of the lead researchers—lead authors Guangjie Zheng and Yang Wang, and Jian Wang, principal investigator of the Aerosol and Cloud Experiments in the Eastern North Atlantic [https://www.arm.gov/publications/backgrounders/docs/doe-sc-arm-16-020.pdf] (ACE-ENA) campaign—began their involvement with the project while working at Brookhaven and have remained close collaborators with the Lab since moving to Washington University in St. Louis in 2018.

The study made use of a long-term ground-based sampling station on Graciosa Island in the Azores (an archipelago 850 miles west of continental Portugal) and a Gulfstream-1 aircraft outfitted with 55 atmospheric instrument systems to take measurements at different altitudes over the island and out at sea. Both the ground station and aircraft belong to the DOE Office of Science’s Atmospheric Radiation Measurement (ARM) user facility [https://www.arm.gov/], managed and operated by a consortium of nine DOE national laboratories.

The team flew the aircraft on “porpoise flights,” ascending and descending through the boundary layer to get vertical profiles of the particles and precursor gas molecules present at different altitudes. And they coordinated these flights with measurements taken from the ground station.

The scientists hadn’t expected new particle formation to be happening in the boundary layer in this environment because they expected the concentration of the critical precursor trace gases would be too low.

“But there were particles that we measured at the surface that were larger than newly formed particles, and we just didn’t know where they came from,” Kuang said.

The aircraft measurements gave them their answer.

Many of the choreographed flight paths for this study traversed the open ocean and also crossed within the ranges of the ground-based scanning radars at DOE’s Atmospheric Radiation Measurement (ARM) Climate Research Facility on Graciosa Island in the Azores.

“This aircraft had very specific flight patterns during the measurement campaign,” Kuang said. “They saw evidence that new particle formation was happening aloft—not at the surface but in the upper boundary layer.” The evidence included a combination of elevated concentrations of small particles, low concentrations of pre-existing aerosol surface area, and clear signs that reactive trace gases such as dimethyl sulfide were being transported vertically—along with atmospheric conditions favorable for those gases to react with sunlight.

“Then, once these aerosol particles form, they attract additional gas molecules, which condense and cause the particles to grow to around 80-90 nanometers in diameter. These larger particles then get transported downward—and that’s what we’re measuring at the surface,” Kuang said.

“The surface measurements plus the aircraft measurements give us a really good spatial sense of the aerosol processes that are happening,” he noted.

At a certain size, the particles grow large enough to attract water vapor, which condenses to form cloud droplets, and eventually clouds.

Both the individual aerosol particles suspended in the atmosphere and the clouds they ultimately form can reflect and/or absorb sunlight and affect Earth’s temperature, Kuang explained.

Study implications

So now that the scientists know new aerosol particles are forming over the open ocean, what can they do with that information?

“We’ll take this knowledge of what is happening and make sure this process is captured in simulations of Earth’s climate system,” Kuang said.

Another important question: “If this is such a clean environment, then where are all these precursor gases coming from?” Kuang asked. “There are some important precursor gases generated by biological activity in the ocean (e.g., dimethyl sulfide) that may also lead to new particle formation. That can be a nice follow-on study to this one—exploring those sources.”

Understanding the fate of biogenic gases such as dimethyl sulfide, which is a very important source of sulfur in the atmosphere, is key to improving scientists’ ability to predict how changes in ocean productivity will affect aerosol formation and, by extension, climate.

The research was funded by the DOE Office of Science, DOE’s Atmospheric System Research, and by NASA. In addition to the researchers from Brookhaven Lab and Washington University, the collaboration included scientists from Pacific Northwest National Laboratory; Missouri University of Science and Technology; the University of Washington, Seattle; NASA Langley Research Center; Science Systems and Applications Inc. in Hampton, Virginia; the Max Planck Institute for Chemistry in Mainz, Germany; and the Scripps Institution of Oceanography, University of California, San Diego.

Accelerator physicist Chuyu Liu, the run coordinator for this year's experiments at the Relativistic Heavy Ion Collider (RHIC), in the Main Control Room of the collider-accelerator complex at Brookhaven National Laboratory.

Final stage of Beam Energy Scan II will collect low-energy collision data needed to understand the transition of ordinary nuclear matter into a soup of free quarks and gluons

Accelerator physicists are preparing the Relativistic Heavy Ion Collider (RHIC), a DOE Office of Science user facility for nuclear physics research at DOE’s Brookhaven National Laboratory, for its 21st year of experiments, set to begin on or about February 3. Instead of producing high-energy particle smashups, the goal for this run is to maximize collision rates at the lowest energy ever achieved at RHIC.

STAR co-spokesperson Lijuan Ruan noted that this year’s run is the third and final leg of Beam Energy Scan II, a systematic study of RHIC collisions at low energies.

“Run 21 is the final step of Beam Energy Scan II (BES-II), a three-year systematic study of what happens when gold ions—gold atoms stripped of their electrons—collide at various low energies,” said Brookhaven physicist Lijuan Ruan, co-spokesperson for RHIC’s STAR experiment collaboration.

Nuclear physicists will examine the BES-II data, along with data from RHIC’s high-energy collisions, to map out how these collisions transform ordinary protons and neutrons into an extraordinary soup of free quarks and gluons—a substance that mimics what the early universe was like some 14 billion years ago. By turning the collision energy down, RHIC physicists can change the temperature and other variables to study how these conditions affect the transition from ordinary matter to early-universe hot quark-and-gluon soup.

“Out of the five energies of BES-II—9.8, 7.3, 5.75, 4.6, and 3.85 billion electron volts, or GeV—this year’s run at 3.85 GeV is the most difficult one,” said Brookhaven Lab accelerator physicist Chuyu Liu, the run coordinator. That’s because “RHIC’s beams of gold ions are really difficult to hold together at the lowest energy,” he explained.

In Run 21, the accelerator team will use a variety of innovative components and schemes to maintain the lifetime and intensity of the colliding ion beams under challenging conditions. Read on to learn more about RHIC’s Run 21 science goals and the accelerator features that will make the science possible.

Scanning the transition

Mapping nuclear phase changes is like studying how water changes under different conditions of temperature and pressure (net baryon density for nuclear matter). RHIC’s collisions “melt” protons and neutrons to create quark-gluon plasma (QGP). STAR physicists are exploring collisions at different energies, turning the “knobs” of temperature and baryon density, to look for signs of a “critical point.” That’s a set of conditions where the type of transition between ordinary nuclear matter and QGP changes from a smooth crossover observed at RHIC’s highest energies (gradual melting) to an abrupt “first order” phase change that’s more like water boiling in a pot.

As Ruan explained, the quest to map out the phases of nuclear matter and the transitions between them is somewhat similar to studying how water molecules transform from solid ice to liquid water and gaseous steam at different temperatures and pressures. But nuclear matter is trickier to study.

“We need a powerful particle collider and sophisticated detector systems to create and study the most extreme forms of nuclear matter,” she said. “Thanks to the incredible versatility of RHIC, we can use the ‘knob’ of collision energy and the intricate particle-tracking capabilities of the STAR detector to conduct this systematic study.”

RHIC’s highest collision energies (up to 200 GeV) produce temperatures more than 250,000 times hotter than the center of the Sun. Those collisions “melt” the protons and neutrons that make up gold atoms’ nuclei, creating an exotic phase of nuclear matter called a quark-gluon plasma (QGP). In QGP, quarks and gluons are “free” from their ordinary confinement within protons and neutrons, and they flow with virtually no resistance—like a nearly perfect liquid.

But QGP lasts a mere fraction of a second before “freezing out” to form new particles. RHIC physicists piece together details of how the melting and refreezing happen by taking “snapshots” of the particles that stream out of these collisions.

By systematically lowering the collision energy, the physicists are looking for signs of a so-called “critical point.” This would be a set of conditions where the type of transition between ordinary nuclear matter and QGP changes from the smooth crossover observed at RHIC’s highest energies (picture butter melting gradually on a counter), to an abrupt “first order” phase change (think of how water boils suddenly at a certain temperature and holds that temperature until all the molecules evaporate).

As physicists turn RHIC’s collision energy down, they expect to see large event-by-event fluctuations in certain measurements—similar to the turbulence an airplane experiences when entering a bank of clouds—as conditions approach a “critical point” in the nuclear phase transition. This year’s run at the lowest collision energy will contribute to this search.

“Theorists have predicted that certain key measurements at RHIC will exhibit dramatic event-by-event fluctuations when we approach this critical point,” Ruan said.

Some RHIC physicists liken these fluctuations to the turbulence an airplane experiences when it moves from smooth air into a bank of clouds and then back out again. Measurements from phase I of RHIC’s Beam Energy Scan (BES-I, with data collected between 2010 and 2017) revealed tantalizing hints of such turbulence. But because collisions are hard to achieve at low energies, the data from BES-I aren’t strong enough to draw definitive conclusions.

Now, in BES-II, a host of accelerator improvements have been implemented to maximize low-energy collision rates.

Cooling the ions

One of the innovations that Chuyu Liu and the other Collider-Accelerator Department (C-AD) physicists managing RHIC operations will take advantage of in Run 21 is a first-of-its-kind beam-cooling system. This Low Energy RHIC electron Cooling  (LEReC) system operated at full capacity for the first time in last year’s RHIC run, making it the world’s first implementation of electron cooling in a collider. But it will be even more important for the lowest-of-low collision energies this year.

“The longer the beam stays at low energy, the more ‘intra-beam scattering’ and ‘space charge’ effects degrade the beam quality, reducing the number of circulating ions,” said Liu. Simplistic translation: The positively charged ions tend to repel one another. (Remember: The ions are atoms of gold stripped of their electrons, leaving a lot of net positive charge from the 79 protons in the nucleus.) The scattering and the repulsive space charge cause the ions to spread out, essentially heating up the beam as it makes its way around the 2.4-mile-circumference RHIC accelerator. And spread-out ions are less likely to collide.

A host of accelerator improvements have been implemented to maximize RHIC’s low-energy collision rates. These include a series of components that inject a stream of cool electron bunches into the ion beams in these cooling sections of the two RHIC rings. The cool electrons extract heat to counteract the tendency of RHIC’s ions to spread out, thereby maximizing the chances the ions will collide when the beams cross at the center of RHIC’s STAR detector.

“The LEReC system operates somewhat similar to the way the liquid running through your home refrigerator extracts heat to keep your food cool,” said Wolfram Fischer, Associate Chair for Accelerators in C-AD, “but the technology needed to achieve this beam cooling is quite a bit more complicated.”

A series of components (special lasers and a photocathode gun) produces bunches of relatively cool electrons, which are accelerated to match the bunching and near-light-speed pace of RHIC’s ions. Transfer lines inject the cool electrons into the stream of ion bunches—first in one RHIC ring, then, after making a 180-degree turn, into the other. As the particles mix, the electrons extract heat, effectively squeezing the spread-out ion bunches back together. The warmed-up electron bunches then get dumped and replaced with a new cool batch.

“To add more flexibility for cooling optimization during this year’s run at RHIC’s lowest energy, where the space-charge effects and beam lifetime degradation are concerns for both the electrons and the ions, we installed a new ‘second harmonic’ radiofrequency (RF) cavity in the electron accelerator,” said Alexei Fedotov, the accelerator physicist who led the LEReC project.

These cavities generate the radio waves that push the electrons along their path, with the higher (second harmonic) frequency helping to flatten out the longitudinal profile of the electron bunches. “This should help to reduce the space charge effect in the electron beams to achieve better cooling performance at low energy,” Fedotov said.

“We plan to commission the new electron beam transport line in late January and start cooling ions with the new electron beam setup in early February,” he added.

More accelerator advances

Similarly, third-harmonic RF cavities installed in the ion accelerator rings will help to flatten the longitudinal profile of the ion bunches, reducing their peak intensity and space charges, Liu explained. “With that, more bunch intensity can be injected into RHIC to produce higher luminosity—a measure closely tied to collision rates,” he said.

The accelerator team will also be commissioning a new bunch-by-bunch feedback system to help stabilize the beam for a better lifetime. “This system measures how each ion bunch deviates from the center of the beam pipe, and then applies a proportional correction signal through a component called a kicker to nudge each bunch back to where it should be,” Liu said.

All this cooling and nudging will counteract the ions’ tendency to spread, which maximizes chances of collisions happening when the two beams cross at the center of STAR.

“This run will bring together many of the advances we’ve been working on at RHIC to meet the challenging conditions of low-energy collisions,” said Fischer. “STAR would have preferred to test the lowest energy first, but we needed to learn everything possible (and develop the electron cooling system) before we could embark on operation at the most difficult energy.”

RHIC operations are funded by the DOE Office of Science.

On January 8 the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory welcomed the first virtually visiting researchers to the Laboratory for BioMolecular Structure (LBMS), a new cryo-electron microscopy facility. DOE’s Office of Science funds operations at this new national resource, while funding for the initial construction and instrument costs was provided by NY State. This state-of-the-art research center for life sciences imaging offers researchers access to advanced cryo-electron microscopes (cryo-EM) for studying complex proteins as well as the architecture of cells and tissues.

Many modern advances in biology, medicine, and biotechnology were made possible by researchers learning how biological structures such as proteins, tissues, and cells interact with each other. But to truly reveal their function as well as the role they play in diseases, scientists need to visualize these structures at the atomic level. By creating high-resolution images of biological structure using cryo-EMs, researchers can accelerate advances in many fields including drug discovery, biofuel development, and medical treatments.

This first group of researchers from Baylor College of Medicine used the high-end instruments at LBMS to investigate the structure of solute transporters. These transporters are proteins that help with many biological functions in humans, such as absorbing nutrients in the digestive system or maintaining excitability of neurons in the nervous system. This makes them critical for drug design since they are validated drug targets and many of them also mediate drug uptake or export. By revealing their structure, the researchers gain more understanding for the functions and mechanisms of the transporters, which can improve drug design.  The Baylor College researchers gained access to the cryo-EMs at LBMS through a simple proposal process.

“Our experience at LBMS has been excellent. The facility has been very considerate in minimizing user effort in submission of the applications, scheduling of microscope time, and data collection,” said Ming Zhou, Professor in the Department of Biochemistry of Molecular Biology at Baylor College of Medicine.

All researchers from academia and industry can request free access to the LBMS instruments and collaborate with the LBMS’ expert staff.

“By allowing science-driven use of our instruments, we will meet the urgent need to advance the molecular understanding of biological processes, enabling deeper insight for bio-engineering the properties of plants and microbes or for understanding disease,” said Liguo Wang, Scientific Operations Director of the LBMS. “We are very excited to welcome our first visiting researchers for their remote experiment time. The researchers received time at our instruments through a call for general research proposals at the end of August 2020. Since September, we have been running the instruments only for COVID-19-related work and commissioning.”

LBMS has two cryo-electron microscopes—funded by $15 million from NY State’s Empire State Development—and the facility has space for additional microscopes to enhance its capabilities in the future. In recognition of NY State’s partnership on the project and to bring the spirit of New York to the center, each laboratory room is associated with a different iconic New York State landmark, including the Statue of Liberty, the Empire State Building, the Stonewall National Monument, and the Adam Clayton Powell Jr. State Office Building.

“By dedicating our different instruments to New York landmarks, we wanted to acknowledge the role the State played in this new national resource and its own unique identity within Brookhaven Lab,” said Sean McSweeney, LBMS Director. “Brookhaven Lab has a number of facilities offering scientific capabilities to researchers from both industry and academia. In our case, we purposefully built our center next to the National Synchrotron Light Source II, which also serves the life science research community. We hope that this co-location will promote interactions and synergy between scientists for exchanging ideas on improving performance of both facilities.”

Brookhaven’s National Synchrotron Light Source II (NSLS-II) is a DOE Office of Science User Facility and one of the most advanced synchrotron light sources in the world. NSLS-II enables scientists from academia and industry to tackle the most important challenges in quantum materials, energy storage and conversion, condensed matter and materials physics, chemistry, life sciences, and more by offering extremely bright light, ranging from infrared light to x-rays. The vibrant structural biology and bio-imaging community at NSLS-II offers many complementary techniques for studying a wide variety of biological samples.

“At NSLS-II, we build strong partnership with our sister facilities, and we are looking forward to working closely with our colleagues at LBMS. For our users, this partnership will offer them access to expert staff at both facilities as well as to a versatile set of complementary techniques,” said NSLS-II Director John Hill. “NSLS-II has a suite of highly automated x-ray crystallography and solution scattering beamlines as well as imaging beamlines with world-leading spatial resolution. All these beamlines offer comprehensive techniques to further our understanding of biological system. Looking to the future, we expect to combine other x-ray techniques with the cryo-EM data to provide unprecedented information on the structure and dynamics of the engines of life.”

LBMS operations are funded by the U.S. Department of Energy’s Office of Science. NSLS-II is a DOE Office of Science user facility.

If doctors could somehow stick numerous miniature flashlights in human bodies and see beneficial or harmful reactions, they would be able to diagnose and treat people who came into their offices.

That’s what Vanessa Sanders, Assistant Scientist at Brookhaven National Laboratory, is working to develop, although instead of using a flashlight, she and her colleagues are using radioisotopes of elements like arsenic. Yes, arsenic, the same element at the center of numerous murder mysteries, has helpful properties and, at low enough concentrations, doesn’t present health threats or problems.

Arsenic 72 is useful in the field of theranostics, which, as the name suggests, is a combination of therapeutics and diagnostics.

Isotopes “allow us to observe visual defects and through using these radioactive agents, we can also observe the functionality of organs,” Sanders explained in an email. These agents can assist in diagnosing people, which can inform the treatment for patients.

What makes arsenic 72 and other radioisotopes helpful is that they have a longer half-life than other isotopes, like fluorine 18, which only lasts for several minutes before it decays. Arsenic-72 has a half life of 26 hours, which matches with the life of an antibody, which circulates through bodies, searching for targets for the immune system. The combination of arsenic-72 and arsenic-77 allows the former to act as a diagnostic agent and the later as a therapeutic partner.

By attaching this radioisotope to antibodies of interest, scientists and doctors can use the decay of the element as a homing device. Using Positron Emission Tomography, agents allow for the reconstruction of images based on the location of detected events.

“When you want to use an antibody as a target for imaging, you want an isotope that will be able to ride with the antibody and accumulate at an area of interest,” Sanders said.

A radiochemist, Sanders is working to develop systems that help researchers and doctors diagnose the extent of problems, while also tracking progress in fighting against diseases. She is working to produce arsenic-72 through the decay of selenium-72.

Using the Brookhaven Linac Isotope Producer, scientists produce selenium-72. They then create a generator system where the selenium 72 is absorbed onto a solid substrate. As it decays, the solid substrate is washed to obtain arsenic-72.

Sanders is hoping to create a device that researchers could ship to clinical institutions where institutions could use arsenic-72 in further applications.

The system BNL is creating is a research and development project. Sanders and her colleagues are working to optimize the process of producing selenium-72 and evaluating how well the selenium, which has a half life of eight days, is retained and how much they can load onto generators.

“We want [arsenic 72] in a form that can easily go into future formulations,” Sanders said. “When we rinse it off that column, we hope to quickly use it and attach it to biomolecules, antibodies or proteins and use it in a biological system.”

With the increasing prevalence of personalized approaches to diseases, Sanders explained that the goal with these diagnostic tools is to differentiate the specific subtype.

A person with pancreatic cancer, for example, might present a specific target in high yield, while another patient might have the same stage cancer without the same high yield target.

“We want to have different varieties or different options of these diagnostic tools to be able to tailor it to the individual patient,” explained Sanders.

Cathy Cutler, Director of the Medical Isotope Program at BNL, said the isotopes Sanders is working on “have a lot of promise” and are “novel.” She described Sanders as “very organized” and “very much a go-getter.”

Cutler said the department feels “very lucky to get her and have her in the program.”

In her group, Sanders explained that she and her colleagues are eager to develop as many radioisotopes as possible to attach them to biomolecules, which will enable them to evaluate disease models under different scenarios. Other researchers are working with arsenic-77, which acts as a therapeutic agent because it emits a different particle.

Scientists are working on a combination of radioisotopes that can incorporate diagnostic and therapeutic particles. When the arsenic 77 destroys the cells by breaking the DNA genetic code, researchers could still observe a reduction in a tumor size. Depending on the disease type and the receptor targeted, scientists could notice a change by observing less signal.

Sanders is working on attaching several radioisotopes to biomolecules and evaluating them to see how well they are produced and separated.

“We make sure [the isotope] attaches to the thing it’s supposed to stick to” such as an antibody, she said.

A resident of Sound Beach, Sanders grew up in Cocoa, which is in central Florida. When she was younger, she wanted to be a trauma surgeon, but she transitioned to radioisotopes when she was in college at Florida Memorial University. “I liked the problem solving aspect of chemistry,” she said. While she works with cancer, she said she would like to investigate neurological diseases as well.

Sanders, who has been living on Long Island since 2017 when she started her post doctoral work at BNL, enjoys the quieter, suburban similarities between the island and her earlier life in Florida.

At six feet, one and a half inches tall, Sanders enjoys playing center on basketball teams and, prior to the pandemic, had been part of several adult leagues in the city and on Long Island, including Ladies Who Hoop and LI Hoops. She is also involved in a sorority, Zeta Phi Beta Sorority Inc, that contributes to community service efforts.

Sanders and her fiancee Joshua Morancie, who works in IT support, had planned to get married in July. They set a new date in the same month next year. If the pandemic continues to derail their party plans next year, the couple plan to wed in a smaller ceremony.

As for radioisotopes, Sanders hopes people become inspired by the opportunities radioisotopes provide for science and medicine.

“There are so many good things that come out of radioisotopes,” Sanders said. “There are so many promising advantages.”

Even as the pandemic continues to cast a pall over the prospects for the economy, the federal government is finding ways to support science. Recently, as a part of a $625 billion award to a host of institutions, the Department of Energy earmarked $115 million over five years for a part of a project led by Brookhaven National Laboratory.

The science, called quantum information systems, could have applications in a wide range of industries, from health care to defense to communications, enabling higher levels of artificial intelligence than the current binary system computers have used for decades. By benefiting from the range of options between the 0s and 1s that typically dictate computer codes, researchers can speed up and enhance the development of programs that use artificial intelligence.

The investment “underscores the confidence the federal government has with respect to how important this technology is,” said James Misewich, the Associate Laboratory Director for Energy and Photon Sciences at BNL. “Despite the challenges of the time, this was a priority.”

Local leaders hailed the effort for its scientific potential and for the future benefit to the Long Island economy.

“I have seen strong support inside of Congress and the administration for funding requests coming out of the Department of Energy for ideas on how to move the DOE’s mission forward,” said U.S. Rep. Lee Zeldin (R-NY-1). “I have also seen a very high level of appreciation and respect for BNL, its leadership, its staff, its mission and its potential.”

Zeldin said the average American spends more time than ever engaging with technologies and other discoveries that were made possible by the first quantum revolution. “Here we are on the verge of a second quantum revolution and BNL is at the forefront of it,” Zeldin said.

Zeldin sees limitless possibilities for quantum information science, as researchers believe these efforts will lead to advancements in health care, financial services, national security and other aspects of everyday life. “This next round of quantum advancements seeks to overcome some of the vulnerabilities that were identified and the imperfections in the first wave,” he said.

State Senator James Gaughran (D-Northport) expects quantum science to provide a significant benefit to the region. “We believe this is going to be a major part of our economic future,” he said. “It is a huge victory for Long Island.”

The return on investment for the state and the federal government will also materialize in jobs growth. This is “going to employ a lot of people,” Gaughran said. “It will help to rebuild the type of economy we need on Long Island. The fact that we are on the front lines of that will lead to all sorts of private sector development.”

While the technology has enormous potential, it is still in early enough stages that research groups need to work out challenges before they can fully exploit quantum technology. BNL, specifically, will make quantum error correction a major part of their effort.

As quantum computers start working, they run into a limitation called a noisy intermediate scale quantum problem, or NISQ. These problems come from errors that lower the confidence of getting the right answer. The noise is a current limitation for the best quantum computers. “They can only go so far before you end up with an error that is fatal” to the computing process, Misewich said.

By using the co-design center for quantum advantage, Misewich and his partners hope to use the materials that “beat the NISQ error by having the combination of folks with a great team that are all talking to one another.”

The efforts will use a combination of classical computing and theory to determine the next steps in the process of building a reliable quantum information system-driven computer.

Misewich’s group is also focusing on communication. The BNL scientists hope to provide a network that enables distributed computing. In classical computing, this occurs regularly, as computer scientists distribute a problem over multiple computers.

Similarly, with quantum computing, scientists plan to distribute the problem across computers that need to talk to each other.

Misewich is pleased with the combination of centers that will collaborate through this effort. “The federal government picked these centers because they are somewhat complementary,” he said. The BNL-led team has 24 partners, which include IBM, Stony Brook University, SUNY Polytechnic Institute, Yale University, Princeton University, the Massachusetts Institute of Technology, Harvard University, Columbia University and Howard University, among others.

“We had to identify the best team and bring in the right people to fill the gaps,” Misewich explained.

Using a combination of federal funds and money from New York State, BNL plans to build a new beamline at the National Synchrotron Lightsource II, which will operate at very low temperatures, allowing scientists to study the way these materials work under real word conditions.

BNL would like the work they are doing to have an application in calculations in three areas: the theory of the nucleus, quantum chemistry, which explores ways to design better materials, and catalysis.

A quantum computer could help make inroads in some challenging calculations related to electron-electron interactions in superconducting materials, Misewich said, adding that the entire team feels a “tremendous sense of excitement” about the work they are doing.”

Indeed, the group has been working together for close to two years, which includes putting the team in place, identifying the problems they want to tackle and developing a compelling strategy for the research to make a difference.

The group is expecting to produce a considerable amount of research and will likely develop various patents that will “hopefully transfer the technology so companies can start to build next generation devices,” Misewich said.

Along with local leaders, Misewich hopes these research efforts will enable the transfer of this technology to a future economy for New York State.

This effort will also train a numerous graduate and post doctoral students, who will be the “future leaders that are going to drive that economy,” Misewich said.

The research will explore multiple levels of improvement in the design of quantum computers which they hope will all work at the same time to provide an exponential improvement in the ability of the computer to help solve problems and analyze data.

Ever since Ancient Romans and Greeks looked to the stars at night, humans have turned those pinpricks of light that interrupt the darkness into mythological stories.

Two years from now, using a state-of-the-art telescope located in Cerro Pachón ridge in Northern Chile, scientists may take light from 12 billion light years away and turn it into a factual understanding of the forces operating on distant galaxies, causing the universe to expand and the patterns of movement for those pinpricks of light.

While they are awaiting the commissioning of the Vera C. Rubin Observatory, researchers including Brookhaven National Laboratory Physicist Anže Slosar are preparing for a deluge of daily data — enough to fill 15 laptops each night.

An analysis coordinator of the Large Synoptic Survey Telescope’s dark energy science collaboration, Slosar and other researchers from around the world will have a unique map with catalogs spanning billions of galaxies.

Anže Slosar

“For the past five years, we have been getting ready for the data without having any data,” said Slosar. Once the telescope starts producing information, the information will come out at a tremendous rate.

“Analyzing it will be a major undertaking,” Slosar explained in an email. “We are getting ready and hope that we’ll be ready in time, but the proof is in the pudding.”

The Vera C. Rubin Observatory is named for the late astronomer who blazed a trail for women in the field from the time she earned her Bachelor’s Degree from Vassar until she made an indelible mark studying the rotation of stars.

Slosar called Rubin a “true giant of astronomy” whose work was “instrumental in the discovery of dark matter.”

Originally called the Large Synoptic Survey Telescope (LSST), the Rubin Observatory has several missions, including understanding dark matter and dark energy, monitoring hazardous asteroids and the remote solar system, observing the transient optical sky and understanding the formation and structure of the Milky Way.

The study of the movement of distant galaxies, as well as the way objects interfere with the light they send into space, helps cosmologists such as Slosar understand the forces that affect the universe as well as current and ancient history since the Big Bang.

According to Slosar, the observatory will address some of its goals by collecting data in five realms including examining large structures, which are clustered in the sky. By studying the statistical properties of the galaxies as a function of their distance, scientists can learn about the forces operating on them.

Another area of study involves weak lensing. A largely statistical measure, weak lensing allows researchers to explore how images become distorted when their light source passes near a gravitational force. The lensing causes the image to appear as if it were printed on a cloth and stretched out so that it becomes visually distorted.

In strong lensing, a single image can appear as two sources of light when it passes through a dense object. Albert Einstein worked out the mathematical framework that allows researchers to make these predictions. The first of thousands of strong lensing effects was discovered in 1979. Slosar likens this process to the way light behind a wine glass bends and appears to be coming from two directions as it passes around and through the glass.

The fourth effect, called a supernova, occurs when an exploding star reaches critical mass and collapses under its own weight, releasing enough light to make a distant star brighter than an entire galaxy. A supernova in the immediate vicinity of Earth would be so bright, “it would obliterate all life on Earth.”

With the observatory scanning the entire sky, scientists might see these supernova every day. Using the brightness of the supernova, scientists can determine the distance to the object.

Scientists hope they will be lucky enough to see a supernova in a strongly lensed galaxy. Strong lensing amplifies the light and would allow scientists to see the supernova that are otherwise too distant for the telescope to observe.

Finally, the observatory can explore galaxy clusters, which are a rare collection of galaxies. The distribution of these galaxies in these clusters and how they are distributed relative to each other can indicate the forces operating within and between them.

The BNL scientist, who is originally from Slovenia, is a group leader for the BNL team, which has seven researchers, including post docs. As the analysis coordinator of the dark energy science collaboration, he also coordinates 300 people. Their efforts, he said, involve a blend of independent work following their particular interests and a collective effort to prepare for the influx of data.

Slosar said his responsibility is to have a big-picture overview of all the pieces the project needs. He is thrilled that this project, which was so long in the planning and development stage, is now moving closer to becoming a reality. He said he has spent five years on the project, while some people at BNL have spent closer to 20 years, as LSST was conceived as a dark matter telescope in 1996.

Scientists hope the observatory will produce new information that informs current understanding and forms the basis of future theories.

As a national laboratory, BNL was involved in numerous phases of development for the observatory, which had several different leaders. The SLAC National Accelerator in Stanford led the development of the camera that will be integrated into the telescope. BNL will also continue to play a role in the data analysis and interpretation.

“Fundamentally, I just want to understand how the universe operates and why it is like this and not different,” said Slosar.

Ivar Strand had to put on a suit at home to interview virtually for a new job.

In the midst of the pandemic, Brookhaven National Laboratory was looking for a Manager of Research Partnerships in the Strategic Partnership Program and, despite the fact that the lab was limiting the people who were on site, was moving forward to fill a job opening.

“It was a strange situation,” Strand said, but the job piqued his interest, particularly because he’d be working with Martin Schoonen, the leader of BNL’s Strategic Partnership Programs office and an associate laboratory director for environment, biology, nonproliferation and national security. Schoonen and Strand, who worked together at Stony Brook in the late 1990’s, have known each other for over 25 years.

While Strand worked at Stony Brook as an Assistant Vice President of Sponsored Programs, he had a visiting appointment at BNL for five years, from 2005 to 2010. Several of the staff at BNL “remembered who I was, which made the transition a little bit easier,” he said.

Strand most recently worked at Long Island University, where he was the Executive Director in the Office of Sponsored Projects.

Schoonen was pleased to welcome Strand to the BNL fold. “[He is] taking on a pivotal role to develop contractual arrangements with potential partners and assist with growing and diversifying the labs funding sources,” Schoonen said in a statement.

In effect, Strand is facilitating collaborations among institutions. He will facilitate not only the connections and collaborations, but also encourage broadening and deepening professional connections to create either project specific or ongoing strategic partnerships

Strand will work to increase the awareness of the capabilities BNL can provide to researchers, entrepreneurs, and investors. The main drawback in a job he started on May 26 has been that he hasn’t been able to “build face-to-face relationships,” he said. Speaking with people for the first time through web-based platforms is not the same as running into someone who is walking across the site.

Building the relationship with the Department of Energy also represents a new challenge for Strand, who has previously worked with educational institutions as well as with Northwell Health.

“I spent my whole career building partnerships at various research institutions,” he said. After facilitating those collaborations, Strand has entered into agreements and then moved one. At BNL, he has the added dynamic of “making sure it satisfies the requirements of the DOE.” The scope of his work comprises all the research funding coming into the lab outside of the direct money that comes from the DOE, which represents about 90 percent of the funds for research at the lab.

Some of these other initiatives are collaborative, which involve DOE funds that also have a requirement to find a company to contribute financially, such as the Technology Commercialization Fund.

Working with finance and departmental business managers, Strand oversees the non-direct DOE money that comes in. When educational institutions and companies participate, particularly to supply funding, Strand and the strategic partnership team become a part of the conversation.

BNL often competes against the other national labs for major projects. Once the government selects a winner, as it did for the construction of the Electron Ion Collider, the DOE often asks the lead on the project to tap into the expertise and talents of the other institutions. When BNL recently won the EIC contract over Jefferson Laboratory in Virginia, the DOE asked BNL to partner with Jefferson to build the facility. New York State originally agreed to contribute $100 million to the construction of the EIC. Strand said the lab is hopeful that the commitment would come through.

In addition to the scientific discoveries that the EIC will bring, it is also a construction project that will provide the state with jobs. “I’m involved in some of the discussions in order to provide information about the project,” Strand said.

The transition to a government lab will require Strand to maneuver through structured agreements from the DOE, which is a bit of a challenge. The DOE uses structured agreements, while educational institutions also do but often are willing to use the agreements the sponsors propose.

Strand is pleased that BNL recently received approval to participate in the Atom Consortium, which was started by Glaxo and the University of California at San Francisco. The negotiation had been going on for several years. “It allows us to enhance our big data computing capabilities and expertise,” he explained.

Strand is excited about rejoining BNL. “I’ve always wanted to work in the lab and understand how best to build collaborations under the government umbrella,” he said.

Strand hoped his unconventional approach to some of the partnership challenges will work in the context of the structured environment of a national laboratory.

Indeed, in 2007, when he was working at Stony Brook, the university received the funds to buy a supercomputer. The two institutions, however, had decided to house the supercomputer at BNL, which made it a “challenging transaction” for all parties. He and others had to help Stony Brook become an enlisted partner, which allowed BNL to house the supercomputer on site.

In the bigger picture, Strand said he and Schoonen are reviewing where the lab will be from a strategic perspective in five years. In addition to industry, they are looking to collaborate with other federal sponsors with whom they haven’t traditionally partnered. They have to make sure that these efforts conform with DOE’s growth agenda.

A first-generation American whose parents were born in Norway, Strand said his parents met in the United States. A resident of South Setauket, Strand lives with his wife Maritza, who is an implementation specialist for ADT payroll. A tennis player and golfer, Strand alternates visiting and hosting his brother, who lives in Norway and is a veterinarian.

Strand is looking forward to his ongoing collaborations with Schoonen. “Having worked with him in the past, I have a lot of respect” for Schoonen, Strand said. “I jumped at the chance to be reunited with him. He’s an unbelievably great guy to work for.”

The show must go on, even in science.

After 70 years of bringing residents into their high tech facility to see some of the cutting-edge technology for themselves and to interact with the scientists from around the world who ask questions about the nature of matter, the universe, energy, weather and myriad other questions, Brookhaven National Laboratory plans to continue the tradition of Summer Sundays, albeit virtually.

Starting this Sunday, Aug. 16, with a virtual explanation video and question and answer session with several scientists, the Department of Energy laboratory will welcome those curious about their labs back, albeit virtually. The first session will begin with a video about the National Synchrotron Lightsource II, a facility that cost close to $1 billion to construct and that has numerous beamlines that enable researchers to see everything from the molecules of a battery in action to cutting edge interactions in biochemistry.

This week’s session, which will run from 3:30 to 5 p.m. will be available on BNL’s YouTube channel. Participants who would like to ask questions during the session can submit them in writing through the lab’s social media accounts or by sending an email to [email protected]. A moderator will direct questions to a panel. The other programs are on August 23rd for the Center for Functional Nanomaterials and August 30th for the Relativistic Heavy Ion Collider.

“Summer Sundays are a large public event and clearly that’s not something anyone is doing right now,” said Kahille Dorsinvil, Principal Stakeholder Relations Specialist and Summer Sundays Coordinator at BNL, who has been working at BNL for 14 years. “People probably thought they’d see us in 2021, [but] we’re still doing science and we’re still trying to share what we’re doing.”

The virtual event has the advantage of allowing the lab to serve as a host for a much larger group of people, who aren’t limited by seats or by social distancing rules. “We tried to make it so there was no limit to who could watch or participate with us online,” explained Dorsinvil.

Participants will watch a short video tour and will then have an opportunity to interact with panelists. The videos will include footage shot from numerous angles.

The participants during a typical in-person Summer Sundays event range across the age spectrum, as BNL promotes the effort as a family event.

Summer Sundays appeal to residents who have already attended similar events in prior years. Indeed, when the lab asks visitors if this is their first time, about half have been to the site before. “Some are our best friends come every year,” Dorsinvil said.

Dorsinvil grew up on Long Island, visiting the lab when she was in ninth grade at Newfield High School in Selden. Through the program, and apprenticeship program, which currently exists as STEM prep for rising tenth graders, she focused on a different science topic each week, including basic chemistry and the environment.

Dorsinvil was already interested in science, but visiting BNL “made a difference in how I continued” in the field, she said.

Seven students took top honors and 15 others received honorable mentions in the first-ever virtual version of the annual elementary school science fair sponsored by the U.S. Department of Energy’s Brookhaven National Laboratory in Upton. Girls and boys in kindergarten to grade 6 entered 129 science and engineering projects for the competition. They represented 38 elementary schools across Suffolk County.

The seven students to receive top honors as well as medals and ribbons are kindergartener Jude Roseto of Cutchogue East Elementary School, Mattituck-Cutchogue Union Free School District, “Friction with Bubbles”; first grader Emerson Spooner of Raynor Country Day School, “Save the Earth: One Plastic Straw at a Time”; second grader Sara Jain of Tamarac Elementary School, Sachem Central School District, “Shrink It Up”; and third grader Mia Trani of Fort Salonga Elementary School, Kings Park Central School District, “Housing the Homeless.”

Top honors also went to fourth grader Rebecca Bartha of Raynor Country Day School, “Dynamic Duckweed: A Solution to Pollution in Local Water”; fifth grader Reilly Riviello of Cherry Avenue Elementary School, Sayville Public Schools, “What Material is the best to protect your property from Flash Flooding” and sixth grader Emma Tjersland of Hauppauge Middle School, Hauppauge School District, “Drug Facts: Impacts of Medicine Exposure on Daphnia Magna Heart Rate.”

“Thinking like scientists and engineers is so important for students — asking questions, testing assumptions, drawing conclusions, and thinking about future research,” said Amanda Horn, a Brookhaven Lab educator who coordinated both the virtual science fair and a new Science Share program. “The Lab has hosted science fairs for years to encourage students and we didn’t want COVID-19 to stop us in 2020.”

Science fairs at Brookhaven Lab were typically held in person at the Lab site and students, their families, teachers, and school administrators were invited to attend. With schools closed and Brookhaven Lab’s site mostly inaccessible to limit the spread of COVID-19, Horn, Scott Bronson and their colleagues in Brookhaven’s Office of Educational Programs (OEP) quickly adjusted plans to hold the 2020 science competition virtually.

As in years past, students first qualified for the Lab’s fair by winning their schools’ “local” science fairs, some of which were also held virtually. Projects completed by individual students and groups were accepted — one project per grade per school.

Instead of bringing projects to Brookhaven Lab for an all-day on-site event, parents and teachers submitted photos of students’ projects. OEP staff then distributed the photographs and a rubric among 23 judges, comprising Brookhaven Lab scientists, engineers, and technical staff as well as teachers from local elementary schools. To maintain objectivity and limit potential biases, information such as students’ names, schools, and districts was not shared.

The 15 students who received Honorable Mentions were kindergarteners Taran Sathish Kumar of Bretton Woods Elementary School, Hauppauge School District, “Strength of Spaghetti” and Evelyn Van Winckel of Fort Salonga Elementary School, Kings Park Central School District, “Are Your Hands Clean?”; first-graders Mason Rothstein of Lincoln Avenue Elementary School, Sayville Public Schools, “3,2,1…Let It Rip” and John Henry of Frank J. Carasiti Elementary School, Rocky Point Union Free School District, “Lego Rubber Band Cars”; and second-graders Agnes Van Winckel of Fort Salonga Elementary School, Kings Park Central School District, “The Flight of a Football” and Cassie Danseraeu and Katelynn Hausmann of West Middle Island Elementary School, Longwood Central School District, “Can Aloe Vera Juice Save Strawberries from Mold?”

Honorable mentions were also given to third-graders Mihir Sathish Kumar of Bretton Woods Elementary School, Hauppauge School District, “Strength of Electromagnets” and Matthew Mercorella of Sunrise Drive Elementary School, Sayville Public Schools, “Think Twice Before Melting the Ice”; fourth-graders Samuel Canino of R.J.O. Intermediate School, Kings Park Central School District, “Riddled With Puck Shot,” Jack Gomez of R.J.O. Intermediate School, Kings Park Central School District, “Infinipower” and Madelyn Kalinowski of Laurel Hill School, “Wash Away Germs”; fifth-graders Alexandra Barry of Remsenburg-Speonk Elementary School, Remsenburg-Speonk Union Free School District, “Mutiny on the Bounty” and Gavin Pickford of R.J.O. Intermediate School, Kings Park Central School District, “Is This The Last Straw”; and six-graders Karly Coonan of Raynor Country Day School, “The Last Straw” and Pranav Vijayababu, Hauppauge Middle School, Hauppauge School District, “Save Our Seas.”

“Suffolk County, New York State, the country, and the world need scientists and engineers now and in the future. The students in this science fair are young, but they aren’t too young to have fun with investigative science and engineering processes,” said Scott Bronson, Brookhaven Lab’s manager for K–12 programs.

“Once again, the students who participated were exceptional. Their projects showed it. Congratulations to each of them. And, ‘Thank you,’ to every parent, teacher, mentor, and volunteer who helped them — and will continue to help them along the way.”
