While we have been under a shelter-in-place order in the Bay Area, the ALS community has mostly been telecommuting. We caught up with Angelic Lucero, Karen Nunez, Ina Reichel, Bruce Rude, Ashley White, and Antoine Wojdyla to see how they have been handling this unprecedented experience. Read more »

Study Leads to Firmer Grasp of Biochemical “Reactive Handle”
Protein crystallography provided new insight into a functional group of molecules that, if added to bacterial enzymes, could enable a variety of alterations to the bacteria’s polymer output. Tweaking enzymes to produce these “reactive handles” is a first step toward biosynthesizing diverse polymers with tailored properties. Read more »
Jason Jed, Systems Manager
Before Jason Jed joined the ALS last month, he had already toured the facility in person and through virtual reality. Is it any wonder that he knows some of the more hidden rooms at the ALS? Read more »
Direct Imaging of Fracture Closure in Reservoir Shales
Using x-ray microtomography at the ALS, researchers identified and characterized the microscale factors affecting fluid flow through shale fractures propped open with sand or ceramic spheres. A better understanding of propped fractures can lead to safer and more efficient recovery of hard-to-reach oil and gas resources. Read more »
Assembly Lines for Designer Bioactive Compounds
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.
