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.
Researchers at the Joint BioEnergy Institute and the Great Lakes Bioenergy Research Center used crystallography and biophysical methods to better understand how the NOV1 enzyme breaks down a a stilbene substrate into two smaller compounds. Understanding this unusual chemical reaction brings insight on how to generate desirable biofuels and bioproducts from biomass deconstruction.
Berkeley Lab scientists are developing new ways to see the unseen. Here are seven imaging advances (recently reported in our News Center) that are helping to push science forward, from developing better batteries to peering inside cells to exploring the nature of the universe. 1. Seeing DNA nanostructures in 3-D DNA segments can serve as a
An international team of scientists is providing new insight into the process by which plants use light to split water and create oxygen. In experiments led by Berkeley Lab scientists, ultrafast X-ray lasers were able to capture atomic-scale images of a protein complex found in plants, algae, and cyanobacteria at room temperature.
Berkeley Lab scientists have found a way to engineer the atomic-scale chemical properties of a water-splitting catalyst for integration with a solar cell, and the result is a big boost to the stability and efficiency of artificial photosynthesis. The research comes out of the Joint Center for Artificial Photosynthesis (JCAP), established to develop a cost-effective method of turning sunlight, water, and carbon dioxide into fuel.
A proposed upgrade to the Advanced Light Source—which would provide new views of materials and chemistry at the nanoscale with X-ray beams up to 1,000 times brighter than possible now—has cleared the first step in a Department of Energy approval process. The upgrade would enable new explorations of chemical reactions, battery performance, and biological processes.
