TLDR
Chitin is the most abundant natural amino polysaccharide and is estimated to be produced annually almost as much as cellulose, and recent progress in chitin chemistry is quite noteworthy as mentioned in this paper.Abstract:
Chitin is the most abundant natural amino polysaccharide and is estimated to be produced annually almost as much as cellulose. It has become of great interest not only as an underutilized resource, but also as a new functional material of high potential in various fields, and recent progress in chitin chemistry is quite noteworthy. The purpose of this review is to take a closer look at chitin and chitosan applications. Based on current research and existing products, some new and futuristic approaches in this fascinating area are thoroughly discussed.read more

Synthesis and Characterization of Thermosetting Furan-Based Epoxy Systems
TL;DR: In this paper, analogous furanyl-based and phenyl-based diepoxy monomers were synthesized, and thermosets were prepared using amine curing agents, and a structure-property study showed that furan-based polymers possess improved Tg (Δ = 8-16 °C) and improved glassy modulus ( Δ = 0.1 to 0.6 GPa) relative to their phenylic analogues.

A simple equation for description of solute release I. Fickian and non-fickian release from non-swellable devices in the form of slabs, spheres, cylinders or discs
TL;DR: In this paper, a simple exponential relation Mt/M∞ = ktn is introduced to describe the general solute release behavior of controlled release polymeric devices, where Mt is the fractional release, t is the release time, k is a constant, and n is the diffusional exponent characteristic of the release mechanism.
