This article focuses on the influence of the geometric structure of the polymer chain on the physical properties of polymers. It is shown that for polyheteroarylenes the Kuhn segment calculated based on the geometric structure of the polymer chain has a good correlation with the physical properties of those polymers. For aliphatic polymers, a volume factor is suggested that equals the ratio of the Van der Waals volume of pendant substitute to the volume of the whole polymer chain. It is shown that the properties of aliphatic polymers that depend on free volume are well described by this value. © 2010 Springer Science+Business Media, LLC. Source

Current trends in crystal engineering are critically discussed based on experimental charge density analysis for quantifying various interatomic interactions, from weak van der Waals to coordinate bonds, as applied to the design of crystalline materials. © 2012 Mendeleev Communications.

A method of reductive amination without an external hydrogen source is reported. Carbon monoxide is used as the reductant. The reaction proceeds efficiently for a variety of carbonyl compounds and amines at low catalyst loadings and is mechanistically interesting as it does not seem to involve molecular hydrogen. Look, no H2! Reductive amination without an external hydrogen source has been developed using carbon monoxide as the reductant and rhodium acetate (0.2-1mol %) as catalyst. The method tolerates a variety of functional groups and provides target amines in good to excellent yields. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. Source

Polymeric cryogels, the gels formed in moderately frozen gelling systems, have been empirically known for many decades, but systematic scientific research on various cryogels and the peculiarities of cryotropic gel formation only commenced at the beginning of the 1980s. This historical review briefly describes the principal stages of the studies on these very interesting gel materials. It also discusses some mechanisms of their formation, as well as summarizes published data on the main representatives of chemically crosslinked (covalent), ionically linked, and noncovalent (physical) cryogels. © Springer International Publishing Switzerland 2014.

(Chemical Equation Presented) Trial and error: Topological analysis of the experimental electron density distribution of trinitropyrazole has allowed the energetic consequences of an overlooked pseudosymmetry to be quantified for the first time. This has allowed measurement of how much a small error in the assignment of a space group may cost a crystal structure; in the case of trinitropyrazole this was 8.9 kcalmol-1. © 2011 Wiley-VCH Verlag GmbH & Co.
