Neutron reflectivity and atomic force microscopy results reveal the electroresponsive interfacial structuring and nano-frictional properties of ionic liquid (IL) lubricant mixtures with a polar solvent are strongly dependent on bulk IL concentration.

Absolute reaction rates for the ozonolysis of phenylethylenes in the liquid phase indicate: (i) a Hammett dependence, with [Formula: see text], for the ring-substituted trans stilbenes, (ii) a solvent effect, whereby the ozone attack is promoted by polar solvents, and (iii) no temperature effect between 15 and 35 °C, thus indicating [Formula: see text].

AbstractIn this paper, γ-valerolactone (GVL), a bio-based polar solvent, was applied as green solvent for iron(III)-catalyzed AGET ATRP without any external ligand. GVL is a fully degradable, non-toxic green solvent and has complex ability to iron halide complexes through –OCO- group. GVL as the solvent and the ligand for AGET ATRP of MMA in a controlled manner, as proved by kinetic study, the low PDI values and the increase in polymer molecular weight versus monomer conversion. Chain re-initiation experiments and 1HNMR characterization were conducted to further confirm the living feature.

Abstract The results of theoretical geometry prediction of formamidopyrimidine(fapy)-adenine and fapy-guanine tautomers are presented. Among 54 potential tautomeric structures of fapy-adenine the most stable structure corresponds to the diamino-keto isomer. The solvent effect has insignificant influence on the fapy-adenine tautomers succession. The fapy-guanine has 172 potential isomers. There are three most stable tautomers of this guanine derivative, which may exchange the order depending on the polarity of the environment. In vapour the most probable is the 4-enol-6-keto-diamino tautomer, while in water environment the 4,6-diketo-diamino isomer is dominant. A more polar solvent stabilises more polar fapy-guanine tauto­mers. The geometric parameters and point-atomic charges corresponding to most probable tau­tomers are also supplied.
