Polyphenols alter κ-carrageenan gel mechanics, adhesion, and disintegration
What the study found Plant-derived polyphenols can reprogram kappa-carrageenan (κ-CRG, a seaweed-derived polysaccharide used to form hydrogels) in a structure-dependent way. The authors report that this changes gel mechanics, thermal behavior, adhesion, and how the gels break down in water-based fluids. Why the authors say this matters The authors conclude that this provides a fully…
Dual-network hydrogel ionic diode shows high current rectification
—
in EngineeringWhat the study found The study reports a dual-network hydrogel-based ionic diode that achieved a very high current rectification ratio of 53.9. The hydrogel combines polyvinyl alcohol and polyacrylamide matrices with cationic polydiallyldimethylammonium and anionic poly(sodium 4-styrenesulfonate) polyelectrolytes. Why the authors say this matters The authors say ionic diodes are of interest for flexible electronics…
