Chitin‐Chitosan Cryogels for the Reversible Sequestration and Recovery of Heavy Metals From Wastewater

open access: yesAdvanced Materials Technologies, EarlyView.
Chitin‐chitosan cryogels with degrees of N‐acetylation from 12.2% to 71.4% are fabricated by dissolution, coagulation and lyophilization for the sequestration of heavy metals from water. Colorimetry and differential pulse voltammetry showed controlled adsorption and desorption capacities for As5+, Co2+ and Cu2+, making this material attractive for ...

Degradable Magnetic Composites from Recycled NdFeB Magnets for Soft Actuation and Sensing

open access: yesAdvanced Robotics Research, EarlyView.
This work presents a degradable soft magnetic composite made from recycled NdFeB particles embedded in a gelatin‐based organogel. The material is processed into magnetic sensors and soft robotic components, which can later be dissolved in a green solvent to recover NdFeB magnetic particles.
