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 ...

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 ...

Innovative composite films of chitosan, methylcellulose, and nanoparticles

, 2011
Plastic is readily available and inexpensive, so it is becoming the main material for packaging. Unfortunately plastics do not biodegrade and, if reduced in small pieces, contaminate soil and waterways.
