The 2024 Fall Meeting of the APS Far West Section at Cal Poly Humboldt featured over 100 students presenting research. Inspiring attendees through their expertise and mentorship were ALS colleagues Antoine Islegen-Wojdyla, Hendrik Ohldag, Xiaoya Chong, and Wei “Francis” He. Read more »
Berkeley Lab User Facilities and University of Oklahoma Collaboration Awarded EPSCoR Grant
The ALS, Molecular Foundry, and a partner at the University of Oklahoma were recently awarded a four-year DOE EPSCoR grant to study bio-inspired membranes for recovering rare earth elements from waste streams. This project aims to develop a model for resource recovery applicable across industries. 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 »
How Bulky Molecules Improve Next-Generation Solar Cells
Adding “bulky” organic molecules earlier in solar-film synthesis slows crystal growth, leading to the formation of a protective surface layer that improves durability and efficiency. These next-gen materials could revolutionize solar-cell technology, offering increased efficiency, lower cost, lighter weight, and flexible solar modules. Read more »
Mechanics of a Floating Molecular Layer for CO2 Reduction
Researchers discovered how a layer of organic molecules on a nanoparticle surface detaches to create a highly catalytic pocket for reducing CO2 to CO. The ability to probe molecular-scale events under realistic conditions with nanometer resolution will help guide the design of responsive systems for a wide range of applications, from medicine to optoelectronics.

New Insights Lead to Better Next-Gen Solar Cells
Perovskites show great promise to reduce the costs of solar power but are not yet durable enough to be commercially viable. Researchers used simultaneous characterization techniques to understand why a simplified fabrication process works so well, providing key insights to nudge perovskites closer to commercialization.

Clarifying the FLASH Effect for Cancer Radiation Therapy
To clarify the underlying mechanisms of the FLASH effect, in which the delivery of ultrafast, high-intensity doses of radiation to tumors counterintuitively reduces damage to surrounding healthy cells, researchers directly compared the oxidative effects of conventional and FLASH techniques using x-ray footprinting at the ALS.

A Bio-Inspired Metal-Organic Framework for Capturing Wellhead Gases
Burning of natural gas at oil and gas wells, called flaring, is a major waste of fossil fuels and a contributor to climate change. In this work, researchers synthesized and characterized a metal-organic framework that uses biomimetic chemistry to convert wellhead gases into economically valuable feedstocks for petrochemical products.

Improving Carbon Retention in Grassland Soil from Point Reyes
Soil organic carbon directly influences the life-supporting services provided by soils, including the production of food and the regulation of atmospheric carbon dioxide. To better understand how minerals such as calcium affect carbon accumulation in soil, researchers studied soils collected from Point Reyes National Seashore. Read more »
HyMARC Aims to Hit Targets for Hydrogen Storage Using X-Ray Science
Understanding how materials absorb and release hydrogen is the focus of the Hydrogen Materials Advanced Research Consortium (HyMARC). At the ALS, the HyMARC Approved Program was recently renewed, underscoring the key role that soft x-ray techniques have played in addressing the challenges of hydrogen storage. Read more »
