This year’s Users’ Executive Committee chair first used synchrotrons as a grad student and loved the experience so much she eventually became a beamline scientist at SSRL. She’s excited to work closely with the user community during the ALS Upgrade and is well versed in post-beamtime food options in Berkeley. Read more »
Stacking the Deck for Custom-Built Hybrid Materials
Researchers fabricated an electronically coupled heterostructure from a novel semiconducting 2D polymer and a 2D transition metal dichalcogenide. Dramatic optical and electronic changes emerged as polymer thickness decreased, underscoring the potential for the discovery of emergent phenomena in studies of hybrid heterostructures. Read more »
A 1-Atom-Deep Look at a Water-Splitting Catalyst
X-ray experiments revealed an unexpected transformation in a single atomic layer of a material that contributed to a doubling in the speed of a chemical reaction—the splitting of water into hydrogen and oxygen gases. This process is a first step in producing hydrogen fuel for applications such as electric vehicles powered by hydrogen fuel cells. Read more »
The Odd Structure of ORF8: Scientists Map the Coronavirus Protein Linked to Immune Evasion and Disease Severity
Researchers determined the atomic structure of a coronavirus protein thought to help the pathogen evade and dampen response from human immune cells.

Janice Krueger, Senior Business Manager
Coming from the Office of the Chief Financial Officer, Janice Krueger is no stranger to the Laboratory. She’s excited to get closer to the science by joining the ALS community. Read on to see how she’ll stock her office when we get back on site. Read more »
Newly Discovered Photosynthesis Enzyme Yields Evolutionary Clues
Scientists have discovered a primitive form of rubisco, a photosynthesis enzyme that has helped shape life on Earth. Detailed information about its structure, determined using complementary techniques at the ALS, will help scientists understand how carbon-fixing organisms oxygenated the atmosphere and how modern plants evolved.

New Insights into Lithium-Metal Surface Reactions for Next-Generation Batteries
In this work, researchers studied how CO2 gas modifies the chemical composition of lithium-metal surfaces. A better understanding of the interactions between lithium and surrounding gases will help design stabilization strategies and move from lithium-ion technology to high-energy-density technologies based on lithium metal.

Scientists Design New Framework for Clean Water
A promising solution to water pollution from abandoned copper mines relies on materials that adsorb copper ions from wastewater, but commercially available products lack the required chemical specificity and load capacity. A team of scientists has designed a new crystalline material that targets and traps copper ions from wastewater with unprecedented precision and speed. Read more »
ALS and Molecular Foundry Funded to Lead the Development of New Artificial Intelligence and Machine Learning Tools
DOE recently awarded a combined $8.55 million to two Berkeley Lab-led teams to build new tools that harness the power of artificial intelligence and machine learning. Synchrotron and nanoscience users will benefit from Alex Hexemer’s MLExchange and Andrew Minor’s 4D Camera Distillery, both multidisciplinary projects involving multiple national labs. Read more »
Yang Ha, Chemistry and Materials Postdoc
Synchrotron science is in Yang Ha’s DNA. After getting his PhD from Stanford/SSRL, he joined the ALS in 2018 to study batteries and has branched out to theoretical computation and machine learning. He has also learned useful skills for sharing cutting-edge research with a broader audience. Read more »
