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

Characterization of shrimp shell deproteinization
TL;DR: The kinetic study of the deproteinization clearly revealed a three-step mechanism with very different rate constants, and the variation of these constants with temperature was used to calculate the energies of activation and the frequency factors of collision, thus allowing a new interpretation of the mechanism of dep Proteinization.

Wound healing applications of sericin/chitosan-capped silver nanoparticles incorporated hydrogel.
TL;DR: The antimicrobial activity and wound healing activity of the optimized hydrogel (S/C-SNPs G-1) demonstrated higher bactericidal activity and wounds closure, as supported by results of histopathology.

Preparation and structure of chitosan soluble in wide pH range
Min Fan,Qiaoling Hu,Kai Shen +2 more
TL;DR: In this paper, two kinds of chitosans, namely N-acetylated and N-deacetylation, were prepared by the modified processes, and the results from X-ray diffraction showed that a transformation of crystal structure occurred during the Nacetylization or N deacetylating process with the decrease of crystallinity and expansion of crystal lattices, which can dissolve in both acid and alkali solution.

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.
