In order to understand the influence of composition on oxygen permeability, the morphology of model silicone hydrogels in both the dry and hydrated states was characterized using a variety of techniques (AFM, HAADF-STEM, solid-state NMR, and X-ray sc

Summary As alternative to cobalt based catalysts, various other catalysts based on manganese, iron and/or copper were developed for curing unsaturated polyesters in styrene with a hydroperoxide. This development is based on the simultaneous tuning of

We investigated the functionalization of polymers with pedant ester groups by enzymatic transesterification. By detailed NMR analysis we have shown that while the monomer can be enzymatically modified, surprisingly no reaction was obtained upon polym

An efficient biocatalytic process based on the use of adsorbent resin (in situ substrate feeding and product removal) makes experiments at high substrate concentration possible by overcoming limitations due to substrate and product inhibition. This p

This study is demonstrating the scale up of asymmetric microbial Baeyer-Villiger oxidation of racemic bicyclo[3.2.0]hept-2-en-6-one (1) to the kilogram scale using a 50 L bioreactor. The process has been optimized with respect to bottlenecks identifi
