Magnetization Switching in Highly Magnetostrictive Microstructures
Researchers learned how the size, shape, and orientation of microstructures affect how they switch magnetization directions in response to an applied voltage. The work advances our understanding of strain-responsive composite materials for use in energy-efficient electronic applications such as memory devices, sensors, and actuators. Read more »
Tracking Oxidation in “High-Entropy” Alloys with Multiple Principal Elements
For extreme applications such as nuclear fusion reactors and high-temperature jet engines, scientists are experimenting with “high-entropy” alloys that consist of many metals mixed together in equal proportions. In this work, researchers begin to unravel how these materials degrade under high-temperature oxidative environments. Read more »
Studying Interfacial Effects in Solid-Electrolyte Batteries
An ambient-pressure probe of a solid electrolyte revealed how surface electrochemical mechanisms lead to poor electrolyte performance and battery failure. The results can help scientists engineer better coatings and interfaces, which are essential for building safer and better-performing batteries, particularly for use in vehicles. Read more »

The Spatial Dynamics of Bone Remodeling During Lactation
To mobilize the minerals needed for milk production, osteocytes—the cells responsible for maintaining bone quality—facilitate the release of calcium and other minerals from the bone matrix surrounding them. In this study, researchers investigated how osteocytes balance the rapid release of calcium with maintaining bone integrity. Read more »
Manganese Cathodes Could Boost Lithium-ion Batteries
Rechargeable lithium-ion batteries are used in mobile devices, electric vehicles, and energy storage systems. But supplies of nickel and cobalt, commonly used in the cathodes of these batteries, are limited. New research opens up a potential low-cost, safe alternative in manganese, the fifth most abundant metal in the Earth’s crust. Read more »
Electronic energy transfer ionization in naphthalene–CO2 clusters reveals excited states of dry ice
The interaction between CO2 and polycyclic aromatic hydrocarbons is of interest in astrochemically relevant ices, the transition to renewable energy, and the development of green chemistry. We investigate the VUV excitation of the naphthalene–CO2 complex and observe excited states of CO2 through a newly identified electronic energy transfer ionization mechanism. Read more »
2024 User Meeting Highlights
Another successful ALS User Meeting was held August 12–14, bringing the ALS user community together under the sunny summer skies of Berkeley, California. Over 300 participants enjoyed an engaging program organized by the Users’ Executive Committee (UEC), led by User Meeting organizers Wendy Gu, Devin Grabner, Monsuru Ramoni, and Shan Wu. Read more »
