Watching the structure of glass under pressure

Glass has many applications that call for different properties, such as resistance to thermal shock or to chemically harsh environments. Glassmakers commonly use additives such as boron oxide to tweak these properties by changing the atomic structure of glass. Now …

Reproducing deep-Earth chemistry

A new pressure cell invented by UC Davis researchers makes it possible to simulate chemical reactions deep in the Earth’s crust. The cell allows researchers to perform nuclear magnetic resonance (NMR) measurements on as little as 10 microliters of liquid …

Modeling of silicon nanoparticles for solar energy

Silicon nanoparticles embedded in a zinc sulfide matrix are a promising material for new types of solar cell. Computational modeling by Stefan Wipperman, Gergely Zimanyi, Francois Gygi and Giulia Galli at UC Davis and colleagues shows how such a material …

Probing hydrogen catalyst assembly, part II

Biochemical reactions sometimes have to handle dangerous things in a safe way. New work from researchers at UC Davis and Stanford University shows how cyanide and carbon monoxide are safely bound to an iron atom to construct an enzyme that …

UC Davis work leads to FDA action on antibacterial soaps

On Dec. 16, the U.S. Food and Drug Administration called on manufacturers of antibacterial soaps to demonstrate that the anti-microbial agents have added benefit over  washing with soap and water, and that these additives do not pose unacceptable risks. This …

Rover’s first sample of Martian soil comes up wet

Contributed by Kat Kerlin The Mars Rover Curiosity is all grown up and eating solids. The first solid sample ingested and analyzed by the rover revealed a high percentage of water in the soil. Water molecules bound to fine-grained soil …

Center to clear the air on aerosols’ climate change impact

In some ways, aerosols are the new CO2. Carbon dioxide has earned enormous attention from scientists and the general public regarding its role in climate change. But aerosols – those tiny particles found in clouds, haze, dust, smog, smoke and …
