Article Abstract
Liquid-solid triboelectric nanogenerators (TENGs) offer a viable approach for harvesting water energy to power Internet of Things systems. Semiconductor-based TENGs leveraging the tribovoltaic effect have recently emerged as a focus of research. In this paper, monolayer molybdenum disulfide (ML-MoS) is introduced as a contacting material for fabricating direct current (DC) liquid-solid nanogenerators. At the internal liquid-solid interface, electron transfer is strongly evidenced by Raman and photoluminescence spectra. For the external characteristics, macroscopic DC outputs are assessed under various conditions, with a maximum current density of 11.1 mA m. Correlating external output patterns with interfacial charge dynamics, a complete working mechanism of the liquid-solid tribovoltaic effect is better elucidated. This work advances innovative strategies for water energy harvesting, deepening fundamental insights into liquid-solid interactions and the tribovoltaic effect.

This study systematically investigates the role of nitrogen annealing in enhancing the structural and electrochemical properties of ZnNiO/NF composite anode materials synthesized via hydrothermal methods. By comparing air-annealed and nitrogen-annealed (400 and 600 °C) samples, it is demonstrated that nitrogen annealing at 400 °C induces the densely stacked nanosheet morphology with optimized lattice regularity, which can significantly improve the charge transport kinetics and the interfacial stability. Electrochemical evaluations reveal an outstanding initial discharge capacity of 1873.

Metal-nitrogen-carbon (M-N-C) catalysts display considerable potential as cost-effective alternatives to noble metals in oxygen electrocatalysis. However, uncontrolled atomic migration and random structural rearrangement during pyrolysis often lead to disordered coordination environments and sparse active sites, fundamentally limiting their intrinsic catalytic activities and long-term durability. Herein, a novel strategy is reported for use in directionally regulating atomic migration pathways via the incorporation of a foreign metal (La).

Airborne pathogens and pollution control typically necessitate multiple membranes, each specializing in efficient aerosol filtration, moisture regulation, or antimicrobial protection. Integrating all these functions into a single membrane is highly advantageous but remains inherently challenging due to material incompatibility and inevitable performance trade-offs. Here, we present a photoactive Janus nanofibrous membrane for highly efficient air purification, engineered via sequential electrospinning.

In this study, porous polysiloxane (PS)/multi-walled carbon nanotube (MWCNT) nanocomposite films were developed as high-performance triboelectric layers for flexible triboelectric nanogenerators (TENGs). TENGs convert mechanical motion into electricity and offer a promising solution for self-powered electronic systems. The nanocomposites were fabricated using a doctor blading method, and porosity was introduced a simple, scalable salt-leaching technique.
