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

An adsorption study of Al(III) ions onto chitosan.
TL;DR: The adsorption of Al(III) from aqueous solutions onto chitosan was studied in a batch system and it was suggested that the overall rate of Al (III) ion adsOrption is likely to be controlled by the chemical process.

An approach to understanding the deacetylation degree of chitosan
TL;DR: In this article, the degree of deacetylation of chitosan samples was evaluated using conductimetry and 1 H NMR and the results obtained with these two techniques were in agreement with the known content of the solutions.

Mechanical and water resistance properties of chitosan/poly(vinyl alcohol) films reinforced with attapulgite dispersed by high-pressure homogenization
TL;DR: In this article, the authors disaggregate the crystal bundles of APT by a simple high-pressure homogenization technology at various pressures, and the obtained nanometer APT as an ideal reinforce filler was introduced into chitosan (CS)/poly(vinyl alcohol) (PVA) matrix to derive a series of nanocomposites by the solution casting method.

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.
