Despite the advantageous high specific capacity of lithium metal anodes, challenges such as dendritic growth and the inherent instability of the native solid electrolyte interphase (SEI) film readily give rise to dead lithium formation, increased int...

This study reports a simple, high-performance, and cost-effective hydrovoltaic power generator driven by natural seawater. The device combines 3D porous non-woven fabrics with asymmetric copper–aluminum electrodes, offering flexible design and...

Perovskite solar cell (PSC) performance is critically limited by surface defects and interfacial energy losses at the tin oxide (SnO₂) electron transport layer (ETL). This study investigates the surface modification of SnO₂ using cesium iodide (CsI)...

Electrochemical CO₂ reduction reaction (ECO₂RR) is a promising technology for converting rapidly rising atmospheric CO₂—driven by fossil fuel consumption and industrial processes—into a circular carbon economy. In particular, ECO₂RR is ex...

Lithium–sulfur batteries have become one of the research focuses of scientists over the past decade due to their high theoretical specific capacity (approximately 1670 mAh/g), low cost, and environmental friendliness, and the abundant reserves...

MXenes have attracted considerable attention as anode materials for sodium-ion batteries (SIBs) because of their metallic conductivity, hydrophilic surfaces, tunable surface terminations, and layered structures. However, pristine MXenes are limited b...

Poly(ethylene oxide) (PEO)-based solid polymer electrolytes are regarded as highly promising solid electrolyte materials owing to their favorable chain flexibility. However, their practical application is hindered by low room-temperature ionic conduc...

Lead-ion (Pb²⁺) contamination in drinking water poses a serious threat to public health, but conventional laboratory-based methods rely on bulky equipment and are unsuitable for on-site monitoring. Here, we develop a wireless monitoring system based...

Y-doped HfO₂ ferroelectric thin films were fabricated via the sol–gel chemical solution deposition method. The effects of Y doping concentration, film thickness, and annealing temperature on the structure, morphology, and electrical properties...

In this study, an electrochemical system for methane conversion was developed, employing Ni- and Ce-doped LaCoO₃ perovskite as the anode catalyst in an Na₂CO₃ electrolyte. Structural characterization revealed that the La_1−yCe_yCo_1−xNi_xO₃ (...

We report a low-temperature plasma–liquid synthesis of crystalline β-Ga₂O₃ nanoparticles directly from aqueous solution. Pulsed discharge plasma bubbles generate reactive species that drive in situ dehydration and crystallization, bypassin...
