Scientists used one of the world’s most powerful electron microscopes to map the precise location and chemical type of 23,000 atoms in an extremely small particle made of iron and platinum. Insights gained from the particle’s structure could lead to new ways to improve its magnetic performance for use in high-density, next-generation hard drives.
Berkeley scientists have discovered that electrons in vanadium dioxide can conduct electricity without conducting heat, an exotic property in an unconventional material. The characteristic could lead to applications in thermoelectrics and window coatings.
Scientists have developed a way to use optical microscopy to map thin-film solar cells in 3-D as they absorb photons. The new method could help researchers learn new ways to boost photovoltaic efficiency.
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.
Berkeley Lab-developed tech enabling energy-saving roofs, long-lived batteries, better data from X-ray experiments, safer drinking water, and reduced carbon dioxide in the atmosphere have received 2016 R&D 100 awards.
A “Future Electron Microscopy” workshop held Tuesday, Oct. 11, at the ALS User Support Building showcased the breadth and depth of electron microscopy at Berkeley Lab.
Light-emitting, four-armed nanocrystals could someday form the basis of an early warning system in structural materials by revealing microscopic cracks that portend failure.
A possible secret to increasing the efficiency of perovskite solar cells has been found hidden in the nanoscale peaks and valleys of the crystalline material.
Researchers found how substantial linear defects in a new semiconductor create entirely new properties. Some of these properties indicate the defects might even mediate superconducting states.
Five researchers at Berkeley Lab were named today as recipients of the Early Career Research Program managed by the U.S. Department of Energy’s Office of Science. The program is designed to bolster the nation’s scientific workforce by providing support to exceptional researchers during the crucial early career years, when many scientists do their most formative work.
