Researchers have made the world’s thinnest (one atom thick) magnet that’s chemically stable under ambient conditions. The two-dimensional material, magnetically characterized at the ALS, could enable big advances in next-generation memory devices, computing, spintronics, and quantum physics. Read more »

Exquisitely Selective CO2 Reduction on Silver
Researchers electrochemically reduced CO2 to CO with nearly perfect selectivity over other products by adding an organic compound to the surface of a silver electrode. With theoretical analyses and ALS data, the work revealed the key role of the microenvironment in promoting the conversion of CO2, a greenhouse gas, into useful products. Read more »
Coulombically-stabilized oxygen hole polarons enable fully reversible oxygen redox
We investigate oxygen redox in layered Na2−xMn3O7, a positive electrode material with ordered Mn vacancies. Our results establish a complete picture of redox energetics by highlighting the role of coulombic interactions across several atomic distances and suggest avenues to stabilize highly oxidized oxygen for applications in energy storage and beyond.

2021 User Meeting Highlights
The Advanced Light Source (ALS) held its annual user meeting August 10–13, 2021, co-chaired by Users’ Executive Committee (UEC) members Alex Frano and Hope Michelsen. A benefit of the virtual platform was the increased number of people who could attend; almost 400 attendees on six different continents joined the plenary sessions. Read more »
September 2021 Message from the UEC
Johanna Nelson Weker, UEC chair, celebrates a successful User Meeting. She encourages the user community to get involved by submitting feedback or even joining the UEC. Keep an eye out for the call for new member nominations. Read more »
U.S. Energy Secretary Granholm Visits Berkeley Lab
In a visit to Berkeley Lab on August 20, Secretary Granholm and Congresswoman Barbara Lee met doctoral fellow Mikayla Barry at ALS Beamline 9.3.1. They also heard about extreme ultraviolet lithography and how protein crystallography enabled critical COVID research and Jennifer Doudna’s work on CRISPR. Read more »
A Powerful Infrared Technique Broadens Its Horizons
Scattering-type scanning near-field optical microscopy (s-SNOM) focuses infrared light to dimensions below the diffraction limit, measuring properties with components perpendicular to the sample surface. Researchers have now devised a way to probe components parallel to the sample, where the technique has been less sensitive. Read more »
Machine-Learning Team Receives 2021 Halbach Award
This year’s Halbach Award for Innovative Instrumentation at the ALS went to a team of accelerator physicists and computer scientists who were able to use machine-learning techniques to solve a problem that has plagued third-generation light sources for a long time: fluctuations in beam size due to the motion of insertion devices.

Autonomous Data Acquisition for Scientific Discovery
Researchers at large scientific facilities such as the ALS have applied a robust machine-learning technique to automatically optimize data gathering for a variety of experimental techniques. The work promises to enable experiments with large, complex datasets to be run more quickly, efficiently, and with minimal human intervention. Read more »
2021 Renner Award winner Andrea “Andi” Jones
At this year’s ALS User Meeting, Andrea “Andi” Jones, proposal coordinator in the User Services Office, was honored with the 2021 Tim Renner User Services Award. The ALS Users’ Executive Committee selected Jones for “her dedication and commitment in supporting the User Office that have allowed efficient proposal reviews and beamtime allocations during the pandemic.” Read more »
