A Clearer Look at Lithium-Ion Traffic Jams in Batteries
By directly visualizing the uneven insertion of lithium ions into electrodes with well-defined crystal orientations, researchers learned why fast charging decreases battery lifespan and performance. The work could provide insights into better battery utilization and help investigations of the surface insertion reaction during fast charging. Read more »
Bennu’s Ancient Brine Sheds Light on Recipe for Life
Researchers traced the evolution of minerals (“salts”) in an ancient brine, as recorded 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 water and essential chemical building blocks of life to Earth in the distant past. Read more »
Reaction Mechanism of Commercial Lithium-Ion Battery Cathodes
Researchers used soft x-ray resonant inelastic x-ray scattering at the ALS to understand the role of aluminum doping in improving the stability of commercially used cathode materials for lithium-ion batteries. Read more »
Mind-Blowing Materials: Mimicking Neurons for Faster Computing
Researchers used x-ray absorption spectroscopy and resonant inelastic x-ray scattering at the ALS to uncover the atomic-level mechanism of conductance switching for a neuromorphic material that has the potential for energy-efficient computing. Read more »
Berkeley Lab Helps Explore Mysteries of Asteroid Bennu
The Advanced Light Source and Molecular Foundry provided powerful tools to study asteroid samples returned by NASA’s OSIRIS-REx mission to the asteroid Bennu. Researchers found a telltale set of salts formed by evaporation that illuminate Bennu’s watery past. Read more »
2025 ALS-United New Year’s Message
Interim ALS Director, Andreas Scholl and Interim ALS-U Project Director Dimitri Argyriou usher in 2025 with a message for you on the ALS-U project and the priorities for the new year. Watch their conversation or access the full transcript. Read more »
Autonomous Beamlines: Harnessing Bayesian Optimization to Revolutionize Accelerator Science
Scientists at the Advanced Light Source are developing automated beam optimization systems, collaborating with other light sources to deploy common controls across facilities. Using machine learning, they demonstrated automated beamline alignment that optimizes beam size and flux at the push of a button. Read more »
CU*IP ALS Tours
The American Physical Society holds an annual Conference for Undergraduate Women and Gender Minorities in Physics (CU*IP). This year’s Northern California edition was hosted at UC Berkeley with support from Berkeley Lab and LLNL. After the end of the conference on Sunday, January 26, about 60 participants visited the Lab and got to see NERSC and the ALS. Tour guides for the ALS were Hendrik Ohldag and Ina Reichel, who were also on the local organizing committee of the conference.
