The Advanced Light Source is a U.S. Department of Energy scientific user facility at Lawrence Berkeley National Laboratory. Our mission is to advance science for the benefit of society by providing our world-class synchrotron light source capabilities and expertise to a broad scientific community.

Tuning of One Atomic Layer Unlocks Catalytic Pathway

An atomically precise surface probe helped researchers discover that a catalyst can be activated by tuning the composition of just one atomic surface layer. The work sharpens our understanding of how surface changes can improve the production of hydrogen fuel from water using efficient catalysts made of inexpensive materials.

X-Ray Study Recasts Role of Battery Material from Cathode to Catalyst

Researchers used the ALS to learn about a lithium-rich battery material that has been the subject of much study for its potential to extend the range of electric vehicles and the operation of electronic devices. Through a fundamental spectroscopic study, they not only clarified the reaction mechanism of this material, but also found a conceptually different use of it as a catalyst. Read more »

Winter 2021 Shutdown Recap

During the Winter 2021 shutdown, the ALS was a hive of activity, though social distancing requirements during the pandemic meant that the activity looked a bit different from years past. We began commissioning on March 26 and plan to return to user operations after commissioning concludes. Read more »

Clency Easterling, Senior Material Specialist

Even before joining the ALS in 2015, Clency was impressed by the scientific mission of the facility. Although his work takes him all over the ALS, he is interested in one particular type of research—find out what has captured his attention. Read more »

Coral Skeleton Reveals Hidden Structures under Multimodal Scrutiny

A powerful new microscope combining ptychography with x-ray linear dichroism provides nanoscale insight into the biomineral strength and resilience of a coral skeleton. The technique’s previously unachievable spatial resolution and contrast will open up new lines of research for users of x-ray microscopy at the ALS. Read more »
