Autonomous Solar Metallurgy for High‐Purity Gold Recovery from Electronic Waste
Advanced Science, EarlyView.Inspired by microbial strategies for metal uptake and biomineralization, defect‐rich copper sulfide (Cu31S16) functions as a solar metallurgical platform that unifies Au(III) capture, reduction, and self‐separation. The bioinspired design enables ultrafast gold recovery from electronic‐waste leachates and the spontaneous formation of millimeter‐scale ...

Sorption kinetics for dye removal from aqueous solution using activated clay [PDF]
, 2009 [[abstract]]The kinetics of Basic Red 18 and Acid Blue 9 sorption onto activated clay have been investigated. A batch sorption model, based on the assumption of a pseudo–second order mechanism, has been developed to predict the rate constant of sorption,

Advanced Science, EarlyView.A reversible five‐phase topological cycle is achieved in a minimalist cobalt formate metal–organic framework. The amorphous phase functions as a programmable reactive hub, selectively reconstructing into four distinct crystalline architectures through cationic templates, humidity, or CO2.
