Planning a New Era of Discovery with ALS-U
The ALS is undergoing an ongoing upgrade that will increase our brightness by at least 100 times compared with the current accelerator and improve X-ray coherence. Read about how this leap in brightness will enable groundbreaking sensitivity and precision, empowering researchers to see our world like never before. Read more »
Researchers Confirm Low-Nickel Cathode Resists Degradation
Researchers confirmed that a radially graded, low-nickel cathode sustains reversible oxygen redox across repeated cycling, enabling high capacity with minimal degradation. This cathode could cut nickel usage in electric vehicle batteries, lowering supply risk and financial and environmental costs, while preserving energy density and lifespan. Read more »
Hidden State Precedes Superconductivity in Kagome Metal
Experiments at the ALS revealed a hidden electronic phase that breaks time-reversal symmetry before a charge-density wave forms in a kagome metal. Because hidden electronic order can compete with or shape superconductivity, this finding helps guide the search for high-temperature, unconventional superconducting materials. Read more »
Scientists Uncover How Calcite Repairs Cracks in Its Structure
Researchers uncovered how calcite repairs cracks in its structure over time. These findings could improve reservoir management for extracting resources such as geothermal energy from the Earth. Read more »
ALS-United: Elmie Peoples-Evans and Fernando Sannibale
ALS-United is an opportunity to meet the people collaborating at the Advanced Light Source and the ALS Upgrade project. Hear firsthand how team science enables the cutting-edge research of today and builds the facility of the future. This month, we spoke with Elmie People-Evans, project manager for the ALS Upgrade, and Fernando Sannibale division deputyRead More Read more »
Microscopy Reveals How Early Human Diets Led to Tougher Teeth
Microscopy at the ALS revealed that nanocrystal misorientation in tooth enamel tracked major dietary shifts in primates, contributing to enamel’s resilience. These structural details provide a blueprint for developing tougher, crack-resistant bioinspired materials, next-generation structural ceramics, and coatings. Read more »
