Dye compounds, method of making the compounds and ink composition employing the compounds A dye compound of formula 1: where R and R′ are substituents independently selected from the group consisting of a hydrogen atom, C 1 to C 4 alkyl and a solubilizing moiety comprising a substituted or ...
(see appended drawing in bopi) & lt; br / & gt; & lt; br / & gt; & lt; br / > in which r represents a hydrogen atom or an alkyl radical having from 14 to 20 carbon atoms, and & lt; br / & gt; r1 represents an alkyl radical having from 8 to 18 carbon atoms of 1,....
During initiation, a lipid radical (L) produced after the abstraction of a hydrogen atom reacts with dioxygen to generate a lipid peroxyl radical (LOO). This peroxyl radical then reacts with another lipid to generate another radical (L) and a lipid hydroperoxide (LOOH). It has been ...
ability. Key point: determine the composition of water according to the electrolysis water experiment; explain some phenomena from the point of view of molecule and atom. Difficulty: the division of a single substance or compound; the understanding of the concepts of molecules and atoms. [key ...
an alkyl having from 1 to 20 carbon atoms, monocyclic aryl or a halogen atom, with the proviso that when one of X and Y is carboxy the other of X and Y is a hydrogen atom, that R is lower alkyl or benzyl when X or Y is -SO 2 Cl, and that when the radical of formula XI ...
or higher; and(B) a compound represented by formula (1): ##STR1## wherein R.sup.1 is a hydrogen atom, a lower alkyl group or a group ##STR2## R.sup.2 is a hydrogen atom, a methyl group or a methoxy group; R.sup.3 is a direct bond or a saturated or unsaturated divalent...
The composition contains: (a) polyacrylate polymer of an acrylate of the formula <IMAGE> in which R is the hydrogen atom or the methyl group and R<1> is an alkyl group with 2-4 C atoms, (b) plasticiser for the polyacrylate polymer, (c) lower aliphatic alcohol, (d) mineral filler ...
R<1> and R<2> independently of each other are a hydrogen atom, an alkali or alkaline earth metal cation, an ammonium group, the cation of an ammonium-organic base or a rest Z which stems from a polyhydroxylated organic compound selected from the group comprising etherified (C6-C18)-alkyl...
We demonstrate that SoPIP2;1’s structure, thermodynamics, kinetics, and water transport are altered as a function of each membrane construct’s ensemble properties. Notably, the realistic bilayer provides stabilization of non-functional SoPIP2;1 metastable states. Hydrophobic mismatch and lipid order...
