Reaction Cascades in Polymer Mechanochemistry

Polymer mechanochemistry: Flex, release and repeat.

Mechanochemistry

The scientific community’s general interest in using mechanical energy to trigger or facilitate chemical reactivity has been growing at a speedy pace. In particular, in recent years, organic chemistry has witnessed a constant flow of examples where the use of mechanochemical techniques proved not only to outperform traditional solution-based methodologies, but also enabled access to otherwise i...

Reaction Kinetics in Polymer Melts

We study the reaction kinetics of end-functionalized polymer chains dispersed in an unreactive polymer melt. Starting from an infinite hierarchy of coupled equations for many-chain correlation functions, a closed equation is derived for the 2nd order rate constant k after postulating simple physical bounds. Our results generalize previous 2-chain treatments (valid in dilute reactants limit) by ...

Signaling gradients in cascades of two-state reaction-diffusion systems.

Biological networks frequently use cascades, generally defined as chain-like arrangements of similar modules. Spatially lumped cascades can serve as noise filters, time-delay, or thresholding elements. The operation and functional capabilities of spatially distributed cascades are much less understood. Motivated by studies of pattern formation in the early Drosophila embryo, we analyze cascades...

Advances in industrial biotechnology: synthetic pathways and reaction cascades.

The Center for Biotechnology (CeBiTec) of Bielefeld University, ermany, organizes annual Research Conferences on “Advances in ndustrial Biotechnology”. The 3rd International CeBiTec Research onference entitled “Synthetic Pathways and Reaction Cascades” as held at Bielefeld University in September 2013. Industrial iotechnology is currently evolving driven by a change towards ustainable chemical ...
