Dual Nickel/Photoredox‐Catalyzed Regio‐ and Enantioselective Alkenylation of Epoxides
Advanced Science, EarlyView.Ni/photoredox‐catalyzed stereoconvergent cross‐electrophile coupling of racemic epoxides with alkenyl bromides is described, affording β‐alkenyl products with up to 95% ee, excellent E‐selectivity, and complete regiocontrol. These versatile intermediates enable diverse chiral synthons; mechanistic studies suggest a halide ring‐opening followed by ...

Advanced Science, EarlyView.Polymer‐based hydrogels have emerged as promising materials for atmospheric water harvesting (AWH) due to their high water affinity, tunable network structure, and excellent moisture adsorption‐desorption performance. Functional hydrogel systems enable efficient water capture and controlled release under low‐energy conditions, offering a sustainable ...

Water Quality Trading: Theoretical and Practical Approaches [PDF]
Permit trading as an instrument to control air pollution has already been implemented in several countries, so in Europe since 2005. Could this instrument, however, also be adequately used for water pollution control of river basins in form of a water ...

Electrocatalytic C─C Bond Formation Via Cyanide Interception of CO2 Reduction Intermediates
Advanced Science, EarlyView.ABSTRACT Electrochemical CO2 reduction offers a sustainable route to convert greenhouse gas into high‐value‐added chemicals, yet product distributions remain largely limited to simple C1‐C3 molecules. Here, we report a new reaction in which CO2 reduction intermediates undergo direct C‐C coupling with an external carbon nucleophile under electrochemical
