aAdsorption groups, such as hydroxyl, amine group and ether group, adsorb to clay surface by hydrogen bonds and help to form some solvation film to stabilize the colloid. 吸附小组,例如羟基、胺物小组和以太小组,吸附对黏土表面由氢键并且帮助形成一些溶剂化影片稳定胶体。 [translate] aTAKASAKI TAKASAKI...
Fig. 4: Hydrogen bonds in the synthesis of a rotaxane. Two synthetic strategies involving hydrogen bond interactions, for the formation of a rotaxane. a Capping of a pseudo-rotaxane. b Crown ether active template synthesis. Full size image The first examples of crown ether-based rotaxane with ...
Moreover, Lys802 made a hydrogen bond interaction with one fluorine atom of the trifluoromethyl of Alpelisib. Amide group and residue of Gln859 and Val851 performed a pair of donor–acceptor hydrogen bonds. Compound 8 showed H-bonding with essential Val851 residue and chlorine atom make a H-...

Microcrystalline cellulose can also be used as a slow release agent for medicines. The slow-release process involves the active substance entering the porous structure of the carrier. The active material is contained by intermolecular hydrogen bonds, and the active mate...
N-acylated 11-amino derivatives of papulacandin A or B of the formula I ##STR1## in which Pap is the remainder of papulacandin A or B, R represents methyl or hydrogen and Ac represents the acyl radica
energies contained in the bonds for example the hydrogen bonds, and therefore breaks these bonds and releases the droplets of the three-dimensional network. These temperatures are dependent on the composition of the gel and more particularly on the size of the droplets and the length of the poly...
In addition, a hydrogen bond occurs between the O6 atom of the coordinating guanine and the proximal amine group of the ethylenediamine ligand. The carrier ligands of RAED-C in the guanine adducts appear to form favourable interactions with the double helix, but the conformation of the DNA ...
2,3-BDO can be produced by catalytic hydrogenation of saccharides with hydrogen at elevated pressures and temperatures, Fig.2. Hirth et al. [223] reported that by increasing temperature to approximately 225 °C or higher, selectivity can be shifted toward C2, C3, C4, and/or C6 polyols, suc...
