Latest Update on Long-Term Operating Schedule
The ALS is currently in a long shutdown, and user operations are scheduled to resume on March 15. We anticipate the next shutdown will begin on July 4 and last less than eight weeks. The most up-to-date information can always be found on the Operating Schedule web page. Read more »
Revealing Lithium Metal’s Electronic Structure
Spectroscopy at the ALS and theoretical calculations at the Molecular Foundry revealed the intrinsic spectroscopic signature of lithium metal and explained the origin of previous contradictory reports. The findings provide a benchmark for further studies of lithium compounds towards batteries with higher capacity and energy density. Read more »

Steve Kevan, director of the ALS since 2018, has announced that he will retire later this year. An international search for his replacement will be initiated soon. Read more »
New Technique Visualizes Every Pigment Cell of Zebrafish in 3D
Researchers developed a new technique that uses x-ray microtomography and silver staining to image every pigment cell of a whole zebrafish in 3D. The method could be used to learn more about the 3D architecture of melanoma tumors and potentially guide treatment decisions. Read more »
New Device Advances Commercial Viability of Solar Fuels
A Berkeley Lab research team developed a new artificial photosynthesis device component that exhibits remarkable stability and longevity as it selectively converts sunlight and carbon dioxide into two promising sources of renewable fuels—ethylene and hydrogen. Read more »
Nanoscale Confinement of Photo-Injected Electrons at Hybrid Interfaces
Picosecond time-resolved x-ray photoemission spectroscopy provides real-time electron distributions of donors and acceptors in a prototypical bipyridyl-ZnO hybrid light harvesting system. The measurements show that photo-injected electrons remain localized within the defect-rich surface region of the nanoporous ZnO substrate, revealing a challenge for the extraction of free charge carriers.
