UPTON, N.Y. — Elke Arenholz, a renowned scientist known for her expertise in magnetic materials and X-ray spectroscopy, scattering, imaging, and instrument development, has been named director of the National Synchrotron Light Source II (NSLS-II), a U.S. Department of Energy (DOE) Office of Science user facility at DOE’s Brookhaven National Laboratory, effective August 2024.
Indoor air pollution may have met its match. Scientists have designed lampshades that transform pollutants into harmless compounds. The catalyst-coated lampshades work with halogen and incandescent lamps, and LEDs will be next. The team will present their results at ACS Fall 2023.
How can Marvel movie character Ant-Man produce such strong energy out of his small body? The secret lies in the “transistors” on his suit that amplify weak signals for processing. Transistors that amplify electrical signals in the conventional way lose heat energy and limit the speed of signal transfer, which degrades performance.
Berkeley Lab’s ALS has received federal approval to begin construction on an upgrade that will boost the brightness of its X-ray beams at least a hundredfold. Scientists will use the improved beams for research into new materials, chemical reactions, and biological processes. This construction milestone enables the lab’s biggest project in three decades to move from planning to execution.
New Berkeley Lab breakthroughs: engineering chemical-producing microbes; watching enzyme reactions in real time; capturing the first image of ‘electron ice’; revealing how skyrmions really move
Identifying sources of light plays an important role in the development of many photonic technologies, such as lidar, remote sensing, and microscopy. Traditionally, identifying light sources as diverse as sunlight, laser radiation, or molecule fluorescence has required millions of measurements, particularly in low-light environments, which limits the realistic implementation of quantum photonic technologies. In Applied Physics Reviews, researchers demonstrated a smart quantum technology that enables a dramatic reduction in the number of measurements required to identify light sources
