Researchers successfully bioengineered changes to a molecular “assembly line” for bioactive compounds, based in part on insights gained from small-angle x-ray scattering at the ALS. The ability to re-engineer these assembly lines could improve their performance and facilitate the synthesis of new medically useful compounds. Read more »

Seeing ‘Under the Hood’ in Batteries
To push battery performance, researchers want to learn how the individual ingredients of battery materials behave beneath the surface. But many techniques only scratch the surface of what’s at work inside batteries. A high-sensitivity x-ray technique is attracting a growing group of scientists because it provides a deeper, more precise dive into battery chemistry. Read more »
Staff at Berkeley Lab’s X-Ray Facility Mobilize to Support COVID-19-Related Research
X-rays allow researchers to map out the 3D structure of proteins relevant to diseases at the scale of molecules and atoms, and the ALS has been recalled to action to support research related to COVID-19, the coronavirus disease that has already infected about 2 million people around the world.

Highly Enhanced Curie Temperature in Ga‐Implanted Fe3GeTe2 van der Waals Material
Researchers report an effective and reliable method of increasing the Curie temperature of ferromagnetic Fe3GeTe2 (FGT) van der Waals (vdW) material by Ga implantation, opening a new opportunity for tailoring the magnetic properties of vdW materials beyond room temperature for future spintronics applications.

Debut of ALS-U Swap-Out Injection Video
An entirely new ring— the accumulator—is a key element of the ALS Upgrade (ALS-U) project. But what, exactly, does it do? How does swap-out injection differ from top-off injection, and how does it enable ALS-U? A short, 90-second explainer video provides clear answers to these and other questions. Read more »
The Inside‐Outs of Metal Hydride Dehydrogenation: Imaging the Phase Evolution of the Li‐N‐H Hydrogen Storage System
Hydrogen absorption and release in lithium amide involves chemical and structural change. Scanning transmission x‐ray microscopy visualizes this phase evolution inside particles, showing a core‐shell architecture, with the more hydrogenated species as the shell for hydrogenation and, more surprisingly, for dehydrogenation as well.

Full Energy Range Resonant Inelastic X-ray Scattering of O2 and CO2: Direct Comparison with Oxygen Redox State in Batteries
The evolving oxygen state plays key roles in the performance and stability of high-energy batteries involving oxygen redox reactions. Comparison of the mRIXS profiles of four different oxygen states reveals that oxygen redox states in batteries have distinct widths and positions along the excitation energy. Read more »
March 2020 Update on Proposals and Beamtime
Since Tuesday, March 17, the ALS has been in a warm standby state. Here are details on what that means for user proposals and beamtime. Read more »
March 2020 Message from the UEC
UEC Chair Alex Frano and the rest of the Users’ Executive Committee have been working with ALS management on the 2020 User Meeting and the upcoming shutdown schedule, though some of those discussions are paused during the response to the pandemic. The UEC is here to support and help the user community. Read more »
Jinghua Guo and Yi-De Chuang to be Honored by Professional Societies
The Materials Research Society selected Jinghua Guo to receive the 2020 Innovation in Materials Characterization Award. The American Physical Society recognizes Yi-De Chuang as an Outstanding Referee of the Physical Review journals. Read more »
