The damage and failure mechanism of prestatically loaded rock during medium‐strain rate cyclic impact loading

open access: yesDeep Underground Science and Engineering, EarlyView.
Based on experimental results and theoretical analysis, an established rock damage accumulation model that comprehensively considers the preapplied static load, impact peak value, impact frequency, and impact times. Abstract To study the rock damage mechanism under high static loading and superimposed medium strain rate cyclic impact loading, a series ...

Sustainable Live Sound Monitoring and Classification System Enabled by a Triboelectric Nanogenerator and Machine Learning Techniques

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A high‐performance Triboelectric Nanogenerator (TENG) acoustic sensor using polyimine/graphite polypropylene (PI/GP) was developed for real‐time, sustainable sound monitoring and classification. The self‐powered device delivers 25.67 μW output power, 92.7% accuracy with MobileNet V1, and powers a wireless transmission circuit, demonstrating dual ...

Optimizing Intermediate Adsorption on FeNi3 Alloy by Substrate Defect‐Engineering for Enhanced Oxygen Electrocatalysis

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The presence of carbon edge defects and graphitic valley nitrogen significantly alters the energy band structure of the catalyst, enhancing the desorption of oxygen‐containing intermediates and thereby improving the performance of the oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and zinc‐air battery (ZAB).

GaIn‐Induced Polarization Control in PVDF for High‐Efficiency Energy Harvesting and Instantaneous Wireless Sensing

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study presents a liquid metal–engineered β‐PVDF composite enabling high‐performance piezoelectric–triboelectric nanogenerators. Guided by MD/DFT simulations, GaIn doping promotes β‐phase formation and dipole alignment, while native oxides enhance charge retention.

Ultra‐High Strength and Environmentally Stable Fluorinated Solid‐State Ion‐Conductive Elastomers with Folding‐Paper‐Structured Triboelectric Nanogenerators for Wave Energy Harvesting

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In this work, a polyurethane‐based fluorinated SICEs with excellent mechanical properties (7.35 MPa and 61.4 MJ m−3), conductivity (4.2 × 10−4 S cm−1), and harsh environmental resistance were prepared by a “three birds with one stone” strategy that combines multiple interactions with fluorine effects. The paper‐folding TENG is capable of harvesting not
