Chelation capability of chitosan and chitosan derivatives: Recent developments in sustainable corrosion inhibition and metal decontamination applications

Current Research in Green and Sustainable Chemistry, 2021
Chemically, chitosan is composed of random distributed D-glucosamine and N-acetyl-D-glucosamine units joint together by β-1,4-glycosidic linkage. Chitosan and its derivatives are widely used as corrosion inhibition and removal metallic impurities ...

Concepts for Developing Physical Gels of Chitosan and of Chitosan Derivatives [PDF]

Gels, 2018
Chitosan macro- and micro/nano-gels have gained increasing attention in recent years, especially in the biomedical field, given the well-documented low toxicity, degradability, and non-immunogenicity of this unique biopolymer. In this review we aim at recapitulating the recent gelling concepts for developing chitosan-based physical gels.

WATER-SOLUBLE N -SUBSTITUTED CHITOSAN DERIVATIVES

ASEAN Journal on Science and Technology for Development, 2017
Many water-solubleN-substituted chitosan derivatives have been prepared having the typical -NH-CH2- linkage. Both the Michael reaction and alkylation with monochloroacetic acid at pH 8- 8.5 offer relatively simple ways for their synthesis.

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

Advanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...
