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

Study on antibacterial starch/chitosan blend film formed under the action of irradiation
TL;DR: In this paper, the influence of chitosan and radiation on the properties of the prepared films was investigated, and the tensile strength and the flexibility of starch film were improved largely after incorporation of 20% chitoshan into starch film.
Journal ArticleDOI
Investigation of soil stabilization using chitosan biopolymer
TL;DR: In this article, the potential of chitosan incorporation on mechanical properties of soil has been evaluated comprehensively, and the results show that incorporation has a potential to increase the interparticle interaction of the soil particles which leads to improved mechanical properties.

Chitin and Its Effects on Inflammatory and Immune Responses
TL;DR: Immune recognition of chitin also involves pattern recognition receptors to activate immune cells to induce cytokine production and creation of an immune network that results in inflammatory and allergic responses.

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.
