The angular and temperature dependence of the field-effect mobility are investigated for p-type DNTT single crystals in a vacuum-gap structure. Temperature-independent transport behavior and weak mobility anisotropy are observed, with the best mobility approaching 10 cm2 V-1 s-1. Structural characterization and simulation suggest exceptionally high-quality and high-purity crystals. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

The latest developments in zeolite membranes are reviewed, with an emphasis on the synthesis techniques, including seed assembly and secondary growth methods. This review also discusses the current industrial applications of zeolite membranes, the feasibility of their use in membrane reactors and their hydrothermal stability. Finally, zeolite membranes are compared with metal-organic framework (MOF) membranes and the latest advancements in MOF and mixed matrix membranes are highlighted. © The Royal Society of Chemistry.

Ring opening transesterification polymerization of lactones derived from menthone and carvomenthone was used to synthesize polyols for polyurethane film formulations. The polyols were synthesized at 140°C using tin(ii) octoate as catalyst, diethanolamine as trifunctional initiator, and with ratios of lactone:initiator of 9:1 or 18:1. Polyol structural features were deduced by comparison of NMR spectral data with those of simple model amide/esters of the initiator. Films were formulated from the renewable polyols, diphenylmethane diisocyanate [or poly(diphenylmethane diisocyanate)], and diethylene glycol. Thermal and mechanical properties of these polyurethane films were measured, demonstrating their potential utility as biobased thermosets for rigid or flexible foams.
