Efficient Acidic CO 2 Reduction via Local Strain Engineering of Nickel Single‐Atom Catalysts

ABSTRACT Acidic CO 2 reduction reaction (CO 2 RR) enhances carbon efficiency and electrolyzer stability. Although nickel single‐atom catalysts (Ni‐SACs) effectively convert CO 2 into CO in neutral/alkaline conditions, their performance in acid is hindered by the competing hydroge...

A Dual‐Loss‐Suppression Meta‐Unit for Low‐Loss Continuously Tunable Spoof Surface Plasmon Polaritons

ABSTRACT Dynamic tuning of spoof surface plasmon polaritons (SSPPs) is typically accompanied by substantial loss, which mainly originates from two sources: parasitic loss in tunable semiconductor components and dielectric loss dominated by the substrate. Here, we propose a contin...

An explainable visual structural health monitoring framework for corrosion diagnosis of steel components using high-resolution UAV images

Reliable corrosion monitoring is essential for maintaining the safety, serviceability, and durability of steel structures. However, most vision-based corrosion monitoring methods have been developed for bridges or exterior steel surfaces, and their applicability to indoor industr...

Can the mitigation of water constraints promote regional entrepreneurial activity? Evidence from China

Traditional entrepreneurial choice models typically consider only entrepreneurial talent and capital inputs, neglecting natural resource endowments. The debate over whether the scarcity of natural resources affects regional entrepreneurial activity remains inconclusive. In countr...

Real‐Time Arbitrary Multi‐Bit Phase Manipulation Based on 2‐Bit Digital Spoof Surface Plasmon Polaritons with 360° Phase Coverage

ABSTRACT As a core enabling technology in modern information systems, digital phase manipulation is urgently required to deliver higher phase‐shifting accuracy and enable flexible adjustment of the modulation order. However, conventional digital phase shifters provide fixed phase...

Pressure-gated flexible nanofluidic memristor based on a probe-punctured PDMS membrane

A flexible nanofluidic memristor is demonstrated based on a polydimethylsiloxane (PDMS) membrane containing a single nanopore formed by probe puncturing and controlled by external pressure. A PDMS prepolymer with a base-to-curing agent ratio of 10:1 is cast and cured into a thin,...

Sulfur Cathode Design for Practical Lithium–Sulfur Batteries

Lithium–sulfur (Li–S) batteries are promising candidates for energy storage owing to their high theoretical energy density and low cost. However, challenges remain due to inherent issues such as sluggish redox kinetics and the severe polysulfide shuttle effect of the sulfur catho...

Photonic-crystal hydraulic manometry quantifies epithelial basal compression for rapid, label-free functional screening

Polarized epithelia integrate barrier sealing, vectorial ion-water transport, and cytoskeletal mechanics, yet scalable assays that report this coupled functional state in real time remain limited. Here, we introduce photonic-crystal hydraulic manometry (PCHM), which quantifies ou...

Assessing the Relative Climate Mitigation Effects of Energy Efficiency, Conventional Energy, and Environmental Taxes in Australia: Evidence from a Dynamic ARDL Model

Energy efficiency (EE) is integral to a sustainable energy system and can play a significant role in climate mitigation by reducing energy consumption and the adverse effects of climate change. This paper examines the association between CO2 emissions, EE, environmentally related...
