Researchers have found that under high pressure—comparable to the pressures at which many industrial technologies operate—platinum surfaces can change their structure dramatically in response to the presence of high-coverage reactants. Read more »
Almost all bacteria can form biofilms—dynamic communities of cells enclosed in self-produced matrices of polymers. Researchers have developed a robust and label-free method to probe the chemical underpinnings of developing bacterial biofilms. Read more »
Indium is a key material in lead-free solder applications for microelectronics due to its excellent wetting properties, extended ductility, and high electrical conductivity. Researchers have investigated the small-scale mechanics of indium nanostructures. Read more »
The Berkeley Center for Structural Biology’s Collaborative Crystallography (CC) program is making major advancements in solving protein structures, especially for users involved in high-throughput projects. The CC program is an NIH-funded, peer-reviewed service that allows external users to apply for both beam time and the support of a crystallographer to perform experiments and subsequent data analyses.

Researchers identified the chemical species present for an iron-based Fischer–Tropsch synthesis catalyst and to image their distribution on the nanoscale. When developed further, this new tool may give chemists the ability to design and tailor catalysts for maximum selectivity and efficiency in a wide range of chemical processes. Read more »
Researchers have used an ambient-pressure x-ray photoelectron spectroscopy (APXPS) apparatus to demonstrate that bimetallic nanoparticle catalysts can undergo profound structural and chemical changes in response to reactive environments at ambient pressures, thereby opening the way for engineering catalysts with enhanced activity and selectivity.

NASA’s $200-million, seven-year-long Stardust mission returned to Earth thousands of tiny particles snagged from the coma of comet 81P/Wild 2. Four ALS beamlines and the researchers using them were among the hundreds of scientists and dozens of experimental techniques in facilities around the world that contributed to the preliminary examination of the first samples.

Researchers from The Dow Chemical Company teamed with academic colleagues to conduct x-ray spectromicroscopy studies of superabsorbent polymers (SAPs), materials with a wide range of applications, including disposable baby diapers. Dow has been able to use the results to help develop the process technology for a new SAP-manufacturing plant. Read more »
