Researchers at the Massachusetts Insitute of Technology (MIT) have demonstrated that electronics made from gallium nitride can function even in oven-like temperatures.

Terahertz waves, known as non-ionizing radiation, can turn into ionization radiation when sufficiently many terahertz photons are focused in space and time. A team led by scientists in Korea and the U.S. has created the world's most intense terahertz pulses that can instantaneously ionize atoms and molecules and convert them into plasma.

While it won't make a useful spaceship engine, it may tell us more about relativity.

The production of cement and quicklime is energy demanding and causes high carbon dioxide emissions. This is because the fuel, which is used for heating, and the limestone, which is converted into quicklime at high temperatures, ...

Point defects (e.g. missing, extra or swapped atoms) in crystalline materials often determine the actual electronic and optical response of a given material. For example, controlled substitutions in semiconductors like silicon are the backbone of modern technology. Despite their importance, point defects are notoriously difficult to simulate and characterize, particularly across wide regions of the periodic table.
