Scattering-free subwavelength acoustic direction sensing via virtual acoustic resonance

Conventional direction sensing relies on digital phase extraction after analog-to-digital conversion, which becomes computationally demanding as subwavelength phase differences shrink. Here, we introduce a virtual resonance approach that performs phase-to-amplitude transduction i...

Decomposing Vehicle Production and Consumption Impacts in Japan under Mobility and Production Network Interventions

Abstract Passenger vehicles contribute approximately 8% to global energy-related emissions and drive other environmental impacts through the extraction of raw materials. In this study, a hybrid LCA approach is used to investigate emissions and material life-cycle impacts arising...

Correlated Polymer‐Proton Hopping Enables Water‐Independent Fast Proton Transport in Poly(Ionic Liquid) Membranes

Polymer electrolyte membranes composed of ionic liquids (IL), capable of conducting protons efficiently at elevated temperatures, without external humidification, could transform fuel cell technology. However, the molecular origins of such proton transport remain poorly understoo...

Building a Physics-Aware AI Ecosystem for Solid-State Hydrogen Storage Materials

Abstract Hydrogen storage remains a central bottleneck for scalable hydrogen energy systems due to the multiscale and coupled nature of the thermodynamics, kinetics, and microstructural evolution of hydrogen storage materials (HSMs). Although artificial intelligence (AI) has acce...

Structure–ActivityRelationship in StructurallyDiverse Cobalt Oxide Catalysts for the Electrochemical Reduction ofNitrate to Ammonia

Abstract The electrochemical nitrate reduction reaction (NO3–RR) offers a sustainable method for converting NO3– waste into indispensable ammonia to rebalance the nitrogen cycle, which is considered more severely disturbed than the carbon cycle. Strenuous efforts have already yie...
