Chitin And Chitosan Nanofibers

Abstract: Chitin nanofibers are prepared from the exoskeletons of crabs and prawns, squid
pens and mushrooms by a simple mechanical treatment after a series of purification steps.
The nanofibers have fine nanofiber networks with a uniform width of approximately 10 nm.

Chitosan based edible films and coatings review

Chitosan is a biodegradable biocompatible polymer derived from natural renewable resources with numer-
ous applications in various fields, and one of which is the area of edible films and coatings. Chitosan has

antibacterial and antifungal properties which qualify it for food protection, however, its weak mechanical
properties, gas and water vapor permeability limit its uses. This review discusses the application of chitosan
and its blends with other natural polymers such as starch and other ingredients for example essential oils,
and clay in the field of edible films for food protection. The mechanical behavior and the gas and water
vapor permeability of the films are also discussed. References dealing with the antimicrobial behavior of
these films and their impact on food protection are explored.

A Novel process to prepare chitosan macrospheres without shrinkage

Abstract: A new process for the preparation of chitosan macrospheres, which
was simple and practicable, was suggested in this paper and various chitosans
with different molecular weight were used as materials to immobilize
β-galactosidase and the chitosan macrospheres with the lowest molecular weight
(500 000) was selected as enzyme immobilization carrier based on the highest
enzyme activity.

Flexible and Cellulose-based Organic Electronics


Organic electronics is the study of organic materials with electronic
functionality and the applications of such materials. In the 1970s, the discovery
that polymers can be made electrically conductive led to an explosion within this
field which has continued to grow year by year. One of the attractive features of
organic electronic materials is their inherent mechanical flexibility, which has led
to the development of numerous flexible electronics technologies such as organic
light-emitting diodes and solar cells on flexible substrates.

Piezoelectric sensitivity of a layered film of chitosan and cellulose nanocrystals

Abstract: Free-standing biodegradable films were fabricated by mixing cellulose nanocrystals and nanofibers with a water-based chitosan
solution. The piezoelectric sensitivity of the films was measured to find out their suitability in sensing and actuation applications.
Also their structure was evaluated with scanning electron microscopy. Our initial results show that a simple solvent casting method
can be used to prepare films with varying piezoelectric properties.

A Microwave-Assisted Simultaneous Distillation and Extraction Method

Abstract: An efficient microwave-assisted simultaneous distillation and extraction (MA-SDE) method
has been developed for the separation of polysaccharides and essential oil from Taxus Chinensis var.
mairei. The key operating parameters for MA-SDE were optimized by a single factor and central
composite design experiments and the optimal conditions were found to include a particle size
of 60–80 mesh, liquid/solid ratio of 22.5 mL/g, extraction time of 17.5 min,
