Stress and strain, applied in just the right manner, can sometimes produce amazing results. That is what researchers, led by a team at UC Berkeley’s Department of Electrical Engineering and Computer Sciences, discovered about an emerging semiconductor material—black phosphorous (BP)—used to make two types of optoelectronic devices: light emitting diodes (LEDs) and photodetectors.

Under mechanical strain, BP can be induced to emit or detect infrared (IR) light in a range of desirable wavelengths—2.3 to 5...

Anomalies in the distribution of hydrogen at Occator crater on the dwarf planet Ceres reveal an icy crust, says a new paper led by Tom Prettyman, a Senior Scientist at the Planetary Science Institute.

The evidence comes from data acquired by the Gamma Ray and Neutron Detector (GRaND) aboard NASA’s Dawn spacecraft...

The autoimmune disease lupus may be triggered by a defective process in the development of red blood cells (RBCs), according to a study led by researchers at Weill Cornell Medicine. The discovery could lead to new methods for classifying and treating patients with this disease.

The researchers, who published their findings August 11 in Cell, found that in a number of lupus patients, maturing red blood cells fail to get rid of their mitochondria — tiny molecular reactors that help convert oxygen into chemical energy in most cell types, but are normally excluded from red blood cells...

A research team, led by Professor Guntae Kim in the School of Energy and Chemical Engineering at UNIST has announced a breakthrough in technology that efficiently converts liquid ammonia into hydrogen. Their findings have also attracted significant attention from academic research communities owing to its new analysis protocol, capable of finding optimal process environments.

In this study, the research team succeeded in producing green hydrogen (H2) in large quantities with a purity of nearly 100 percent by decomposing liquid ammonia (NH3) into electricity. Besides, according to the research team, such method consumed three times less power than hydrogen made using electrolysis of water.

Ammonia has emerged as an attractive potential hydrogen carrier due to its extremely high e...
