Abstract: In this work, the kinetics of ethane hydrate formation has been studied experimentally and a kinetic model based on chemical affinity has been described for predicting the hydrate growth process in the stirred batch reactor at a constant volume. The experiments were done with both pure water and aqueous solution of sodium dodecyl sulfate (SDS). The effect of SDS on formation kineti...

a series of sorbents containing various amounts of borate groups were prepared by chemical immobilization ofp-aminoethylphenylboric acid on a copolymer- treated organosilane spacer glass plates. it was found thatbaker's yeast cells selectively adhered to these supports. yeast cells stained with procion red he-3b formeddenser and more stable layer on the copolymer-grafted supports compared onto ...

Knowledge of the electronic structure and properties of element 114 is important for its chemical identification. By comparing its behaviour with that of the lighter group 14 homologues, its position in the periodic table can be confirmed. In this work, we investigate the electron affinity (EA) of element 114, together with its lighter homologues in group 14, Sn and Pb [1]. Electron affinity is...

A new chemical affinity system is described for the purification of proteins. The Linx Affinity Purification System enables researchers to quickly and easily bind a protein ligand to a chromatographic matrix and use the resulting affinity resin to purify a second protein from crude mixtures. The entire process takes approximately 2 h.

in this research at the first, xylometazoline hydrochloride drug (xy) and its fullerene connected form (fxy) were optimized. natural bond orbital (nbo) calculations for these compounds were carried out at the b3lyp/6-31g* quantum chemistry level, in the gas phase and the liquid phase. these calculations can be performed at different accuracy levels depending on the aim of the theoretical study....

Chemical affinity involves the integration of two different types of interaction. One is the interaction operating between a pair of reactants while forming a chemical bond, and the other is the prior interaction between those reactants when they identify a reaction partner. The context of the environments under which chemical reactions proceed is identified by the interaction of the participat...

Here, we report the discovery of first plant-derived and noncanonical epidermal growth factor receptor (EGFR) agonist, 36-residue bleogen pB1 from Pereskia bleo Cactaceae family. We show that is a low-affinity EGFR agonist using suite chemical, biochemical, cellular, animal experiments which include incisor eruption wound-healing mouse models. A focused positional scanning library Ala- d-amino ...
