Piezomagnetic material changes magnetic properties when stretched

20-Mar-2018

Piezoelectric materials, which generate an electric current when compressed or stretched, are familiar and widely used: think of lighters that spark when you press a switch, but also microphones, sensors, motors and all kinds of other devices. Now a group of physicists has found a material with a ...

New X-ray spectroscopy explores hydrogen-generating catalyst

23-Nov-2017

Using a newly developed technique, researchers from Japan, Germany and the U.S. have identified a key step in production of hydrogen gas by a bacterial enzyme. Understanding these reactions could be important in developing a clean-fuel economy powered by hydrogen. The team studied hydrogenases - ...

New, simplified technique makes light metallic nanofoam

06-Nov-2017

A simple method for manufacturing extremely low-density palladium nanofoams could help advance hydrogen storage technologies, reports a new study from the University of California, Davis. A nanofoam is what it sounds like -- a foamy version of some material, filled with very small pores. First ...

New types of structures for cage-like clathrates

08-Mar-2017

Cage-like compounds called clathrates could be used for harvesting waste heat and turning it into electricity. UC Davis chemists just discovered a whole new class of clathrates, potentially opening new ways to make and apply these materials. A clathrate is basically a cage of atoms with another ...

NMR under pressure: Reproducing deep-Earth chemistry

16-Jul-2014

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 at pressures up to 20 kiloBar. "NMR is our ...

Why food quality will suffer with rising CO2

08-Apr-2014

For the first time, a field test has demonstrated that elevated levels of carbon dioxide inhibit plants' assimilation of nitrate into proteins, indicating that the nutritional quality of food crops is at risk as climate change intensifies. Findings from this wheat field-test study, led by a UC ...

New technique makes "biogasoline" from plant waste

05-Feb-2014

Gasoline-like fuels can be made from cellulosic materials such as farm and forestry waste using a new process invented by chemists at the University of California, Davis. The process could open up new markets for plant-based fuels, beyond existing diesel substitutes. "What's exciting is that ...

Unique chemistry in hydrogen catalysts

28-Oct-2013

Making hydrogen easily and cheaply is a dream goal for clean, sustainable energy. Bacteria have been doing exactly that for billions of years, and now chemists at the University of California, Davis, and Stanford University are revealing how they do it, and perhaps opening ways to imitate them. A ...

How seawater could corrode nuclear fuel

31-Jan-2012

Japan used seawater to cool nuclear fuel at the stricken Fukushima-Daiichi nuclear plant after the tsunami in March 2011 -- and that was probably the best action to take at the time, says Professor Alexandra Navrotsky of the University of California, Davis. But Navrotsky and others have since ...

New approach to solar cells

07-Feb-2011

An interdisciplinary team of UC Davis and UC Santa Cruz researchers is taking a novel approach to solar power, one that promises to lead to a technological breakthrough. By using nanoparticles of germanium, silicon and other materials, the researchers hope to produce solar cells far more ...
