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 ...

Cobalt recovery from copper leach solutions [PDF]
"Significant amounts of cobalt, a strategic and critical metal, are present in readily accessible spent copper leach solutions; for example, recovery of cobalt at two major U.S. copper operations could produce about 1,300,000 lb CO annually, about 13 pct

ABSTRACT Current clinical approaches for knee cartilage repair are often limited by hypertrophy and fibrosis in the regenerated tissues. A decellularized tissue‐engineered hyaline cartilage graft (dLhCG), composed of a type II collagen‐based extracellular matrix, has been developed to overcome this limitation.
