Chemical Modification of Flax Reinforced Polypropylene Composites

This paper presents an experimental study on the static and dynamic mechanical properties of nonwoven based flax fibre reinforced polypropylene composites. The effect of zein modification on flax fibres is also reported. Flax nonwovens were treated with zein coupling agent, which is a protein extracted from corn. Composites were prepared using nonwovens treated with zein solution. The tensile, ...

Tissue reactions of polypropylene mesh used in maxillofacial trauma.

Four 1-cm2 fragments of polypropylene mesh were implanted in the subcutaneous tissue of each of 10 albino rats to evaluate biocompatibility. A straight longitudinal incision was made on the back of these animals and histological analysis was carried out at 7, 15 and 30 days. At 7 days, there was a mild inflammatory reaction around the implanted material. On day 15, the inflammatory process cont...

Chemical salt reactions as algebraic hyperstructures

A salt metathesis reaction is a chemical process involving the exchange of bonds between two reacting chemical species, which results in the creation of products with similar or identical bonding affiliations. Hyperstructure theory is studied from the theoretical point of view and for its applications. In this paper, we provide some examples of hyperstructures associated with salt m...

Nonadiabatic chemical reactions

A mixed quantum-classical approach where the environment is treated classically and the reactive degrees of freedom are considered to be quantum mechanical can be used to describe many chemical reactions, such as proton and electron transfer processes. We present reactive flux correlation function expressions for the rate constants of nonadiabatic chemical reactions occurring in quantum-classic...
