Covalent superconductor — Covalent semiconductors are such solids as diamond, silicon, germanium, silicon carbide and silicon germanium where atoms are linked by covalent bonds. Most of those materials, at least in their bulk form, are well studied and rarely hit the… … Wikipedia
Covalent (disambiguation) — Covalent may refer to: Covalent bond, a type of chemical bond Covalent radius, half the distance between two covalently bonded atoms Covalent modulation, the alteration of protein structure by covalent bonding This disambiguation page lists… … Wikipedia
Covalent bond — Covalent redirects here. For other uses, see Covalent (disambiguation). A covalent bond forming H2 (right) where two h … Wikipedia
Covalent organic framework — The design and synthesis of crystalline extended organic structures in which the building blocks are linked by strong covalent bonds are core concepts of covalent organic frameworks (COFs). COFs are porous, and crystalline, and made entirely from … Wikipedia
covalent bond — Chem. the bond formed by the sharing of a pair of electrons by two atoms. [1960 65] * * * Force holding atoms in a molecule together as a specific, separate entity (as opposed to, e.g., colloidal aggregates; see bonding). In covalent bonds, two… … Universalium
Crystal structure of boron-rich metal borides — Two single crystals of YB66 (1 cm diameter) grown by floating zone technique using (100) oriented seeds. In the top crystal, the seed (left from the black line) has same diameter as the crystal. In the bottom crystal (sliced), the seed is much… … Wikipedia
Protein structure — Proteins are an important class of biological macromolecules present in all biological organisms, made up of such elements as carbon, hydrogen, nitrogen, phosphorus, oxygen, and sulfur. All proteins are polymers of amino acids. The polymers, also … Wikipedia
Lewis structure — The Lewis structure of water. Lewis structures (also known as Lewis dot diagrams, electron dot diagrams, and electron dot structures) are diagrams that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist in … Wikipedia
Nucleic acid structure determination — This article is about the experimental determination of nucleic acid structure. For computational methods, see Nucleic acid structure prediction. Structure probing of nucleic acids is the process by which biochemical techniques are used to… … Wikipedia
Primary structure — In biochemistry, the primary structure of a biological molecule is the exact specification of its atomic composition and the chemical bonds connecting those atoms (including stereochemistry). For a typical unbranched, un crosslinked biopolymer… … Wikipedia
