Vacancy-Driven Ni Exsolution in Prussian Blue Analogues Creates Cooperative Defect-Metal Sites for Alkaline Hydrogen Evolution. [PDF]
Adv Sci (Weinh)Multimetal Prussian blue analogues (PBAs) are converted by low‐temperature Ar annealing into a cavity/CN‐vacancy architecture that triggers in situ Ni exsolution, creating dense Ni‐PBA interfacial motifs. These motifs optimize water dissociation and H* adsorption in alkaline media, delivering markedly accelerated HER kinetics and long‐term stability ...

Advancing Energy Efficiency in Smart Windows via Dual-Responsive Electro-Thermochromism. [PDF]
Adv Sci (Weinh)A durable and stable quasi‐solid‐state electro‐thermal dual‐responsive photothermal regulation device has been employed in advanced energy‐efficient smart windows. The devised device not only incorporates a thermochromic hydrogel characterized by high ionic conductivity, high optical transmittance, and a low LCST, but also comprises an electrochromic ...

The Role of Runoff Attenuation Features (RAFs) in Natural Flood Management
Water, 2022 Natural Flood Management (NFM) and catchment-based solutions for flood risk management and environmental problems are wide-ranging and complex. Management of fluvial flood risk in the UK is undergoing a fundamental shift, with a change in emphasis from ...
