Acid Site Design for Low Hydration Proton Exchange Membranes

Advanced Functional Materials, EarlyView.
α‐CF2 substitution adjacent to sulfonic acid increases acid strength and enables efficient proton transport under low hydration conditions. This molecular design reduces the dependence of hydrocarbon proton exchange membranes on excessive water uptake, addressing a key limitation of conventional hydrocarbon PEMs while maintaining favorable conductivity

Mitigating Concentration Polarization in Dry‐Processed Ultra‐Thick Cathodes Using a Low‐Viscosity Electrolyte With Soft Li+ Solvation

Advanced Functional Materials, EarlyView.
A low‐viscosity, soft‐solvating methyl ethanoate (ME)‐based electrolyte facilitates electrolyte infiltration into dense dry‐processed ultra‐thick NCM622 cathodes while reducing Li+ desolvation barriers at Li‐metal anodes. Balanced cathode‐scale ion transport and anode‐side interfacial kinetics mitigate concentration polarization and interfacial ...

Ultrafast Thermal Shock Synthesis of CuNiSnLa Medium‐Entropy Metallic Glass for Sustainable Nitrogen Fixation via Plasma‐Coupled Electrocatalysis

Advanced Functional Materials, EarlyView.
This work introduces an ultrafast thermal shock strategy to synthesize a CuNiSnLa medium‐entropy metallic glass (MEMG). The rapid heating and cooling process generates a robust, highly active catalyst for electrocatalytic nitrate reduction to ammonia (NRA).

Impact of wetting–drying cycles on swelling behavior of clayey soils modified by silica fume [PDF]

, 2011
Expansive clayey soils contain silicate clay minerals that have the potential for swelling and shrinkage under changing moisture contents. Cyclic wetting drying phenomena can cause progressive deformation of expansive clayey soils, which may affect ...

A generalised constitutive model for unsaturated compacted soils considering wetting/drying cycles and environmentally-stabilised line

, 2020
A new Monash – Peradeniya – Kodikara (MPK) generalised model is presented, embodying a volumetric yield surface (i.e. loaded compaction yield surface) derived from constant water content testing, an environmentally-stabilised line representing the states
