A group of researchers led by Drexel University has demonstrated a method that allows scientists to experimentally measure how the chemical bonds of materials are altered when two different materials ...

A hydroquinone-embedded covalent organic framework (Tz-QH-COF) was designed to address photocatalyst instability in ...

For example, oxygen molecules consist of two oxygen atoms joined together. Oxygen atoms can form two covalent bonds, so to link the two oxygen atoms together, a double bond forms between them.

Theory predicts that the bond in this material is much more covalent than typical iron-oxygen bonds, which tend to be quite ionic in most iron-containing compounds.

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, the Nobel Laureate Linus ...

An oxygen atom in the carboxylate forms a strong covalent bond -- a type of bond that involves sharing pairs of electrons between atoms -- with boron. "That covalent bond pacifies the boron ...

Chemistry students the world over are familiar with covalent bonds and hydrogen bonds. Now a study has revealed a strange variety of bond that acts like a hybrid of the two. Its properties raise ...

Home Articles Are 4f-Orbitals Engaged in Covalent Bonding Between Lanthanides and Triphenylphosphine Oxide? An Oxygen K-Edge X-ray Absorption Spectroscopy and Density Functional Theory Study ...

The covalent bond is formed by an oxygen atom that sits between the nitrogen of one amino acid and the sulfur of another and acts like a redox-activated switch for the enzyme.
