Researchers engineered defects in boron nitride to develop a metal-free route for purifying ethylene to remove acetylene. The ALS shed light on how the engineered defects were responsible for exceptional selectivity. Read more »

Altermagnetism All the Way Down
Altermagnets are an emerging class of magnetic materials that offer the potential for energy-efficient, high-density memory chips. Researchers at Penn State, UC Santa Barbara, and the ALS demonstrated that characteristic altermagnetic band splitting in chromium antimonide is evident in thin films relevant for real-world device application.

Berkeley Lab Hosts Agentic AI for User Facilities Workshop
Berkeley Lab hosted a workshop on Agentic AI for User Facilities with about 100 registered participants from user facilities across the US national lab complex and European light sources. The two main goals of the workshop were to identify cross-facility patterns, gaps, and design principles for agentic AI at DOE user facilities, and ground agentic AI in domain realities and identify domain-specific constraints, opportunities, and readiness.

Call for 2025 Publications
All publications resulting from work done in whole or in part at the ALS must be recorded by the User Office for the Department of Energy (DOE). To maintain accurate records and assess the productivity and scientific achievements of our beamlines, please report your ALS publications, especially those published in 2025. Read more »
No Proposal Call This March for August–December 2026
Because the ALS will not offer user beamtime in the second half of 2026, we are not issuing a call for new General User proposals or beamtime requests this March. Please note that RAPIDD access proposals may be submitted at any time. We also anticipate offering a few months of user beamtime in the first half of 2027. Read more »
New UEC Members for 2026
Welcome to new 2026 members Alex Ditter, Brandy Stewart, Baran Eren, Harry Lisabeth, and Simruthi Subramanian! Special thanks to the outgoing members, Quentin Williams, Sophie Morley, Tamas Varga, Leonid Sheps, Aidan Coffey, and Alexander Baker for their service. Read more »
Dynamic Surface Restructuring in Ag–Cu Boosts CO2 Conversion
Multimodal in situ x-ray experiments at the ALS revealed how copper–silver nanoparticle catalysts evolve during CO2 photoreduction. The findings, which demonstrate dynamic catalyst restructuring at the atomic level, provide crucial insights for enhancing the selectivity and efficiency of CO2 conversion into high-value chemicals.

Ancient Asteroid Provides Evidence of Amino Acid Precursors
Researchers identified nitrogen-rich compounds in samples from the asteroid Bennu, returned to Earth by NASA’s OSIRIS-REx mission. The results support the idea that asteroids like Bennu may have delivered the essential chemical building blocks of life to Earth in the distant past. Read more »
200 Scouts Visit the ALS
Berkeley Lab’s Nuclear Science Division hosted another Nuclear Science Day for Scouts. The day’s activities included ALS tours for the scouts. This year a record number of about 200 scouts attended. Read more »
Ian Lacey, Principal Scientific Engineering Associate
The storage ring of the ALS generates incredibly bright beams of x-rays. But they are only useful to users, if we can steer and focus them onto the sample. Ian Lacey, working in the metrology lab of the ALS, helps measure and tune the optical elements needed for that steering. Read more »
