Study shines light on properties and promise of hexagonal boron nitride, used in electronic and photonics technologies

Single-photon emitters (SPEs) are akin to microscopic lightbulbs that emit only one photon (a quantum of light) at a time. These tiny structures hold immense importance for the development of quantum technology, particularly ...

Exploring the potential of single-atom catalysts

There is a high level of interest, even excitement, among chemists and materials scientists about the potential of single-atom catalysts (SACs), but their development relies on very specialized tools available only at synchrotrons ...

New spectrometer helps identify alternative catalyst materials for affordable hydrogen fuel cells

Fuel cells are quickly becoming a viable, clean energy alternative to commonly used fossil fuels, such as gasoline, coal, and oil. Fossil fuels are non-renewable energy resources that release carbon dioxide into the atmosphere.

NASA's IXPE helps researchers maximize 'microquasar' findings

The powerful gravity fields of black holes can devour whole planets' worth of matter—often so violently that they expel streams of particles traveling near the speed of light in formations known as jets. Scientists understand ...

High levels of mercury traced to particular cell types in brains of mammals

Exposure to mercury (Hg) is extremely neurotoxic in most chemical forms. Even scientists who study mercury compounds are at risk due to potential exposure to Hg. Renowned physicist Michael Faraday suffered from Hg poisoning ...
