These new bonds were only discovered in 2016, and are formed when the end of a lysine side-chain is linked to the end of a cysteine side-chain with an oxygen atom linking them together. The NOS ...

A covalent bond is a shared pair of electrons between two non-metal atoms, for example carbon dioxide. Figure caption, Two atoms sharing a pair of electrons.

Uranium forms an unusually strong triple covalent bond with nitrile groups, confounding predictions about the bond strength of actinides compared with the remainder of the periodic table. Elements ...

Drugs that make covalent bonds to biological targets have been around for more than a century. Aspirin. Anti-inflammatory drug. First sold in 1899. Penicillin V. Antibiotic. Discovered in 1928.

BUFFALO, N.Y. and TALLAHASSEE, Fla. — New research shows that curium — one of the heaviest known elements — can be manipulated to a larger degree than previously thought. An international team ...

Researchers have chemically linked 2D materials using a molecular "velcro," resulting in a device with improved optoelectronic properties. The device, made of palladium nanosheets covalently ...

Covalent bonds, in which two atoms are bound together by sharing a pair of electrons, form the scaffolding that underpins the majority of organic compounds. In 1931, ...

Abstract. A detailed electron distribution study of the covalent bond in silicon is discussed. The study is based on the strategy employed earlier to define the covalent bond in diamond, and estimates ...
