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

Effects of chitosan oligosaccharide (COS) on the glycerol-induced acute renal failure in vitro and in vivo.
Hyun Joong Yoon,Myoung E. Moon,Haeng Soon Park,Hyunwoo Kim,Shun Young Im,Jun Haeng Lee,Young Ho Kim +6 more
TL;DR: It was shown that COS recovered the glycerol-induced inflammatory response, renal function factor, and antioxidant effect in kidney and had the antioxidant activity and the anti-inflammatory effect.

Low-temperature and fast response H2S gas sensor using semiconducting chitosan film
TL;DR: In this article, the conductivity of the chitosan film is controlled by blending it with glycerol ionic liquid (IL) with different concentrations 1-9% volume/volume (v/v).

Chitosan coatings onto polyethylene terephthalate for the development of potential active packaging material
TL;DR: In this paper, an advanced surface treatment of PET plastic film is presented for introduction of antimicrobial properties as a potential application for food (as for example meat) packaging material, which was studied using several analytical techniques such as: X-Ray Photoelectron Spectroscopy (XPS), ATR-FTIR spectroscopy and titrations.

Extensively deacetylated high molecular weight chitosan from the multistep ultrasound-assisted deacetylation of beta-chitin.
Anderson Fiamingo,Jorge Augusto de Moura Delezuk,Stéphane Trombotto,Laurent David,Sérgio P. Campana-Filho +4 more
TL;DR: Results revealed that, thanks to the action of high intensity ultrasound irradiation, the USAD process allowed the preparation of unusually high molecular weight, randomly deacetylated chitosan, an important breakthrough to the development of new high grade chitOSan-based materials displaying superior mechanical properties.

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.
