The Third‐Generation Magnetic Super‐Stable Mineralizer: Complete Removal and Separation of Multiple Heavy Metal Pollutants

Advanced Science, EarlyView.
The 3rd‐generation magnetic super‐stable mineralizer M‐MgAl‐700 features a core‐shell structure, strong superparamagnetism, large surface area, and abundant oxygen defects. It achieves exceptional Cd(II) and As(V) mineralization capacities, reducing both pollutants in co‐contaminated water and soil to meet national standards.

One‐Dimensional RuIrTe Nanotubes with Amorphous Surface as a Highly Active and Stable Electrocatalyst Toward Oxygen Evolution Reaction in Acidic Media

Advanced Science, EarlyView.
A rational etching‐induced reconstruction strategy is demonstrated to fabricate one‐dimensional RuIrTe ternary nanotubes with a unique amorphous‐crystalline heterostructure. This hierarchical architecture synergistically optimizes mass transport and electronic configurations, delivering record‐breaking performance in proton exchange membrane water ...

Amplifying effects of land-use change on future atmospheric CO2 levels [PDF]

We constructed a model to analyze the interactions between land-use change and atmospheric CO2 during the recent past and for the future. The primary impact of the conversion of forested lands to cultivated lands is to increase atmospheric CO2, via ...

Ultrafast, High‐Capacity Uranium Harvesting From Seawater via a Hierarchically Porous Polymer Electrode

Advanced Science, EarlyView.
A hierarchically porous AOPIM‐CNT electrode enables uranium harvesting from seawater via adsorption‐promoted electrodeposition. Rapid diffusion and selective adsorption are coupled with electrochemical crystallization and spontaneous detachment, creating a self‐refreshing process that sustains high‐capacity, continuous extraction from ultradilute ...
