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

CuO embedded chitosan spheres as antibacterial adsorbent for dyes
TL;DR: Composite spheres prepared by simple mixing of CuO nanomaterials in CS solution followed by dropwise addition to NH4OH solution were found to be the best adsorbent when applied to remove indigo carmine, congo red and methyl orange from water.

Stability of chitosan nanoparticles for L-ascorbic acid during heat treatment in aqueous solution.
Keum-Il Jang,Hyeon Gyu Lee +1 more
TL;DR: It was confirmed that the stability of AA-loaded CS nanoparticles was affected by temperature but that the internal stability was greater than the surface stability, and it is suggested that the possible use ofAA-loadedCS nanoparticles to enhance antioxidant effects because of the continuous release of AA from CS nanoparticle in food processing is suggested.

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.
