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 »
All News & Updates
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 »
March 2021 Awards and Honors for ALS Users
Ane Etxebarria wins Marie Skłodowska-Curie Fellowship, and DOE recognizes Marca Doeff and Johanna Nelson Weker for their significant contributions to energy storage research. Congratulations to these members of the ALS community on their achievements! 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 »
Study Shines New Light on Li-Battery Cathode Materials
Researchers clarified key reaction mechanisms in a Li-battery cathode material, revealing its surprising utility as a catalyst for next-gen batteries. The work refutes widely held ideas about reversible reactions in a highly debated material for Li-based batteries and expands the range of materials suitable for use in high-power batteries and fuel cells.

Skyrmion Creation and Annihilation Made Simple
Researchers developed a simple approach to writing and deleting skyrmions on demand, using heat and magnetic fields generated by an electrical current, by-products normally considered problematic. The ubiquitous character of these effects, coupled with simplicity of design, offers much-needed scalability and broad applicability. Read more »
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. Read more »
Redirecting dynamic surface restructuring of a layered transition metal oxide catalyst for superior water oxidation
Electrocatalysts, particularly those for water oxidation, often experience substantial or at least partial reconstruction. Here, Wang et al. are able to control surface reconstruction using a cationic redox-tuning method on layered LiCoO2–xClx catalysts for the oxygen evolution reaction. The resulting optimized catalyst exhibits excellent electrocatalytic performance in alkaline electrolyte. Read more »
Mystery Protein Helps COVID–19 Avoid Immunity
Using the Advanced Light Source (ALS), researchers solved the structure of ORF8, a protein specific to SARS-CoV-2. Understanding the structure of ORF8 opens the door to therapy studies targeting SARS-CoV-2, the virus responsible for causing COVID-19. Read more »
Gas-phase synthesis of corannulene—a molecular building block of fullerenes
Fullerenes have been implicated to play a key role in the astrochemical evolution of the interstellar medium. However, the formation mechanism of even their simplest molecular building block—corannulene—has remained elusive. Here we demonstrate that corannulene can be synthesized in the gas phase through reactions mimicking conditions in carbon-rich circumstellar envelopes. Read more »
