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 »

Balanced Charge Transport Optimizes Industry‐Relevant Ternary Polymer Solar Cells
In this article, Szymanski et al. develop novel, cost‐effective ternary polymer solar cells printed in semi‐industrial conditions from a relatively benign ink, which do not require any further processing. These solar cells show good stability and efficiency due to balanced charge-carrier mobilities achieved by optimizing the composition and morphology. Read more »
Rational Design of a Uranyl Metal–Organic Framework for the Capture and Colorimetric Detection of Organic Dyes
Diffraction data for a new uranyl-containing metal–organic framework reveals a structure of interpenetrating 3D nets with large pores. The material is stable in aqueous media and due to the large void space (constituting 76% of the unit cell by volume) can sequester organic dyes, the uptake of which induces a visible change to the color of the material.

X-Rays Reveal Architectural Clues to the Crush-Resistance of Diabolical Ironclad Beetles
The appropriately named diabolical ironclad beetle has an incredibly crush-resistant exoskeleton, which could serve as a blueprint for tougher materials. To see, in microscopic detail, what makes the beetle so uniquely ironclad, researchers used the ALS to explore a protective covering known as the “elytra,” its abdomen, and other parts. Read more »
Experimental Drug Targets HIV in a Novel Way
Researchers from Gilead Sciences Inc. solved the structure of an experimental HIV drug bound to a novel target: the capsid protein that forms a shield around the viral RNA. The work could lead to a long-lasting HIV treatment that overcomes the problem of drug resistance and avoids the need for burdensome daily pill-taking. Read more »
Increasing the Efficiency of CO Catalytic Conversion
Using a combination of tools at the ALS and other facilities, researchers probed specific mechanisms affecting the efficiency of catalysts for CO-to-CO2 conversion. The work brings us closer to the rational design of more effective catalysts for cleaning up toxic CO exhaust and advances our understanding of fundamental catalytic reactions. 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 »
In Memoriam: Alan Jackson, Retired Accelerator Physicist
Alan Jackson led the accelerator physics group of the ALS through its design, construction, and early years of operation. He took an active role in building synchrotrons around the world, and the accelerator physics community will miss both his expertise and joie de vivre. 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 »
ALS Shutdown Schedule for 2021
The ALS will be shut down for the holidays and maintenance beginning Dec. 24; user operations are scheduled to resume on Mar. 30. The summer shutdown is expected to begin in early July and last approximately three months. Over the next few years, shutdowns will likely be longer than in recent years to allow preparation and installation associated with the ALS-U Project. Read more »
