Scientists at Berkeley Lab and the University of Toronto have developed a new recipe for creating synthesis gas mixtures, or syngas, that involves adding a pinch of copper atoms sprinkled atop a gold surface.
Berkeley Lab researchers have developed a new method of analyzing the molecular-scale structure of organo-lead halide perovskites, a promising class of materials that could energize the solar cell industry. They combined advanced X-ray spectroscopy measurements with calculations based on fundamental, “first principles” theory to obtain an atomic-scale view of the material.
X-ray experiments at Berkeley Lab, coupled with theoretical work, revealed how oxygen atoms embedded very near the surface of a copper sample had a more dramatic effect on the early stages of a reaction with carbon dioxide than earlier theories could account for. This work could prove useful in designing new types of materials to make reactions more efficient in converting carbon dioxide into liquid fuels and other products.
The American Academy of Arts and Sciences announced today the election of 188 fellows, five of whom are scientists at Berkeley Lab. The new Berkeley Lab fellows are Jamie Cate, Christopher Chang, Roger Falcone, Michael Witherell and Katherine Yelick. All hold joint faculty appointments at UC Berkeley.
Researchers have found that among the heavy metal elements, berkelium has an unusual characteristic that could potentially be used to distinguish it from other radioactive actinides.
Berkeley Lab researchers have, for the first time, captured the ephemeral electron movements in a transient state of a chemical reaction using ultrafast, tabletop X-ray spectroscopy. The researchers used femtosecond pulses of X-ray light to catch the unraveling of a ring molecule that is important in biochemical and optoelectronic processes.
Berkeley Lab chemists have developed a powerful new method of selectively linking chemicals to proteins, a major advance in the manipulation of biomolecules that could transform the way drugs are developed, proteins are probed, and molecules are tracked and imaged. This technique, called ReACT, is akin to a chemical Swiss army knife for proteins.
Visiting scientists gave input during a workshop last week on the range of new X-ray science made possible by a planned upgrade of the Advanced Light Source.
Defects and jagged surfaces at the edges of nanosized platinum and gold particles are key hot spots for chemical reactivity, researchers confirmed using a unique infrared probe.
A combination of experiments, including X-ray studies at Berkeley Lab, revealed new details about pesky deposits that can stop chemical reactions vital to fuel production and other processes.
