New approach for solving protein structures from tiny crystals

Using x-rays to reveal the atomic-scale 3-D structures of proteins has led to countless advances in understanding how these molecules work in bacteria, viruses, plants, and humans—and has guided the development of precision ...

Cause of cathode degradation identified for nickel-rich materials

A team of scientists including researchers at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and SLAC National Accelerator Laboratory have identified the causes of degradation in a cathode material for ...

Illuminating nanoparticle growth with X-rays

Hydrogen fuel cells are a promising technology for producing clean and renewable energy, but the cost and activity of their cathode materials is a major challenge for commercialization. Many fuel cells require expensive platinum-based ...

Light-activated, single-ion catalyst breaks down carbon dioxide

A team of scientists has discovered a single-site, visible-light-activated catalyst that converts carbon dioxide (CO2) into "building block" molecules that could be used for creating useful chemicals. The discovery opens ...

Making X-ray microscopy 10 times faster

Microscopes make the invisible visible. And compared to conventional light microscopes, transmission x-ray microscopes (TXM) can see into samples with much higher resolution, revealing extraordinary details. Researchers across ...

Electrochemical 'fingers' unlock battery's inner potential

Lithium-ion batteries unleash electricity as electrochemical reactions spread through active materials. Manipulating this complex process and driving the reactions into the energy-rich heart of each part of these active materials ...

New clues about a brain protein with high affinity for Valium

Valium, one of the best known antianxiety drugs, produces its calming effects by binding with a particular protein in the brain. But the drug has an almost equally strong affinity for a completely different protein. Understanding ...

A step toward reduced nitrogen-oxide emissions in vehicles

Stricter environmental regulations enacted in the last few years are putting a squeeze on emissions from car engines, including nitrogen oxide. While modern "lean-burn" gasoline and diesel vehicles use less fuel, they also ...

National Synchrotron Light Source II achieves 'first light'

The brightest synchrotron light source in the world has delivered its first x-ray beams. The National Synchrotron Light Source II (NSLS-II) at Brookhaven Lab achieved "first light" on October 23, 2014, when operators opened ...
