Laplace‐Pressure‐Stabilized Rutile Solid‐Solution Catalysts for Acidic Water Oxidation: Enabling DSA‐Inspired Compositions

Advanced Materials, EarlyView.
The miscibility of foreign elements in rutile‐type IrO2 and SnO2 is greatly enhanced under high Laplace pressure, where their crystal size is reduced to the nanoscale. This enhancement leads to the successful synthesis of DSA‐composition solid‐solution nanocatalysts with notable durability during the acidic OER in water electrolysis.

A Porous Interfacial Photothermal Layer of Fused Core–Shell Carbon‐Polymer Nanospheres for Directional Salt Crystallization and Zero‐Liquid‐Discharge

Advanced Materials, EarlyView.
A hierarchical hydrogel evaporator with a thin, porous photothermal layer of fused core–shell carbon‐polymer nanospheres enables ultrafast interfacial solar evaporation with minimized heat loss and sufficient water supply. Directional advection‐dominated brine transport, coupled with Marangoni‐driven interfacial flow, drives salt away from the active ...

Magnetic‐Field Modulation of Charge Transport in Non‐Fullerene Semiconductors for Enhanced Hydrogen Evolution

Advanced Materials Interfaces, EarlyView.
ABSTRACT This study demonstrates that weak magnetic fields (16–40 mT) increase the efficiency of the hydrogen evolution reaction (HER) in electrocatalysts based on non‐fullerene acceptor (NFA) derivatives IT‐4Cl and Y6. Electrochemical measurements reveal that the application of the magnetic field reduces the onset potential and increases the current ...

Stabilizing Electrochemical Interfaces With Multifunctional Cobalt Nitride Layers

Advanced Materials Interfaces, EarlyView.
Cobalt nitrides emerged recently as an interesting class of earth‐abundant oxygen evolution catalysts. Herein, plasma‐enhanced atomic layer deposition is used to synthesize multifunctional cobalt nitride layers that simultaneously protect and catalytically activate photoelectrode surfaces.

Understanding Links Between Water Scarcity and Violent Conflicts in the Sahel and Lake Chad Basin Using the Water Footprint Concept

Earth's Future
Whilst there are several empirical studies linking water scarcity and violent conflicts, existing quantitative studies use mostly climate and environmental variables even though such variables have been shown to not be strong predictors of water ...
