Giant molecule acceptors (GMAs), known for their large size and intricate functional structures, are an emerging focus in materials science. Through implementation of an interface-enhanced layer-by-layer fabrication strategy, we have successfully demonstrated that GMA with designed electronic structure at interfaces can effectively improve OPV device performance.

In Memoriam: Terry McAfee, Senior Scientific Engineering Associate
The ALS community is saddened to lose Terry McAfee, who was a caring and hardworking presence since he started coming to the facility as a graduate student. From ALS user to full-time staff, he always strove to create a welcoming environment. We will remember his passion for STEM and his love for his family. Read more »
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 »
Summer 2024 Shutdown Recap
The ALS is back in user operation after more than two months of shutdown. By now, more than 80% of the Accumulator Ring (AR) has been installed, as well as both of its radio frequency (RF) cavities. A number of other tasks were also completed. 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 »
Protein Pioneer: Enabling Scientists to Design Novel Proteins for the Future
The 2024 Nobel Prize in Chemistry was awarded to David Baker, Demis Hassabis, and John M. Jumper for the development of protein structure prediction and design. At the ALS, Baker leveraged high-throughput small-angle x-ray scattering (SAXS) and protein crystallography capabilities to design novel proteins and pave a new pathway for science, technology, and the environment.

Elucidating Heterogeneous Li Insertion Using Single-Crystalline and Freestanding Layered Oxide Thin Film
The nanoscale surface insertion of lithium in a single-crystalline and freestanding LiNi1/3Mn1/3Co1/3O2 thin film is elucidated using in situ scanning transmission x-ray microscopy. The realization of advanced analysis through freestanding thin films is expected to be applicable to other systems subjected to external stimuli, such as hydrogen storage alloys, in the field of materials science.
