Chemistry: Vibrations yield new type of bondThe article discusses a chemistry experiment by Jörn Manz and his colleagues from Shanxi University in Taiyuan, China on chemical bonds within molecules like the BrMuBr molecule.doi:10.1038/515011eNature ResearchNature...
Everything in our natural world is made from molecules and these molecules are held intact by chemical bonds. Bonding is fundamental not only for the basics of chemistry and biology, but for everything we experience in our daily lives; the molecules in our food, the proteins in our body, t...
c. hydrogen bondsPolar Molecule:The smallest representative unit of any covalent chemical compound is a single molecule, in which some number of atoms are connected through the sharing of valence electron pairs. A molecule is polar if ...
Network covalent materials, such as diamond, C, silicon, Si, and silicon dioxide (quartz and sand), SiO2, have atoms arranged in an extended 3-dimensional lattice of strong, shared electron pair covalent bonds:Network covalent materials are hard, refractory, brittle, usually electrical insulators,...
Carbon and its bonds are key to understanding chemistry. Here is an overview of the most common type of bond and a few others.
The structure of the AAA/L-Fuc complex consists of a β-jellyroll sandwich composed of three- and five-stranded β-sheets (Fig. 8.3A), which interacts with the α-Fuc ligand throughhydrogen bonds, established between side chains from a trio of basic amino-acid residues (Ne of His51and ...
Explanation of Ionic Sequences in Various Phenomena. IV. General Method for Determination of the Type of Bonding in Polymers; Bonds in Ovalbumin, Ribonuclease, Collagen, Hemoglobin, and Starch DeterminedThe salting-out or -in of hydrocarbons, uncharged nitrogen bases, and acids containing polarized ...
This work’s main objective is to study the origin of some of the physical properties ofEuFeAs2via a detailed investigation of its electronic structure using theab-initiodensity-functional theory calculations. The formation and the type of chemical bonds and the charge transport properties in this...
Salt metathesis of 2,4,6‐triphosphacyclohexadienyl lithium and chlorobis(pentafluorophenyl)borane affords a 1﹑hosphabora‐norbornadiene derivative 2 . The C≡N triple bonds of nitriles insert into the PB bond of 2 with concomitant CB bond cleavage, while the C≡C bonds of phenylacetylenes...
Pharmacophore analysis showed that chamanetin has many hydrogen acceptors and donors which can form interaction bonds with the receptor proteins. Chamanetin passed all the screening analyses, having good absorption, no violation of Lipinski’s rule, nontoxic properties, and good pharmacophore properties...
