Controlled Lattice Distortion and Lattice‐Strain‐Engineered CoCuIr Alloy toward Preferential Chlorine Tolerant Direct Seawater Electrolysis

open access: yesAdvanced Science, EarlyView.
A lattice‐strain‐engineered Co0.28Cu0.67Ir0.05 trimetallic alloy nanoparticle electrocatalyst is rationally designed for efficient alkaline seawater electrolysis. Larger Ir atoms in the CoCu lattice modulate the local coordination environment, generating compressive lattice strain and highly active catalytic sites.

Co‐Ligand‐Induced Electronic Modulation Controls Substrate Adsorption and Selectivity in Biomass Electrooxidation

open access: yesAdvanced Science, EarlyView.
A molecular design strategy is reported that introduces distinct anionic co‐ligands into Cu‐based catalysts to modulate the electronic density of the metal center and, consequently, its interaction with both OHads and HMF. The work establishes co‐ligand engineering as an effective strategy for precise interfacial adsorption control in electrocatalysis,

Ab Initio Thermoelectric Transport Calculations of Alloyed Half‐Heuslers

open access: yesAdvanced Science, EarlyView.
The effect of alloying on the electronic transport of half‐Heusler thermoelectric materials is explored using a fully ab initio approach. A novel method is developed that combines calculations of alloyed supercells with Boltzmann transport, considering the full energy and momentum dependent scattering processes from first principles extracted ...

Circadian‐Inspired Hydrogel Moisture Electricity Generation

open access: yesAdvanced Science, EarlyView.
A circadian‐inspired hydrogel moisture‐electric generator enables sustainable electricity generation by autonomously current direction switching between daytime and nighttime. This reversible output is accompanied by inversion of the internal water gradient, which effectively reduce hydrogel fatigue and offers a new strategy for harvesting diurnal ...

Mixed‐Valence Atomic‐Layer Iridium Patches Enhance Alkaline Hydrogen Evolution

open access: yesAdvanced Science, EarlyView.
Engineering iridium architectures on Cu3P nanowires reveals that atomic‐layer Ir patches form a mixed‐valence interfacial motif with an anisotropic electronic structure. This configuration balances water dissociation and hydrogen adsorption/desorption, delivering superior alkaline hydrogen evolution with a 27 mV overpotential and 1 A cm−2 operation in ...
