Surface activated Ni7Fe3 alloy foam as a self-supported anode for anion exchange membrane water electrolysis

Self-supported electrodes (SSEs) offer a simplified route toward ionomer-free catalyst fabrication for anion exchange membrane water electrolyzer (AEMWE), but most reported systems rely on additional catalyst growth or deposition on porous metallic supports. Here, a commercial Ni...

High-valence Ta5+ doping in Na3V2(PO4)2F3/C cathodes for enhanced sodium storage

Na 3 V 2 (PO 4 ) 2 F 3 (NVPF), as a NASICON-type cathode material, has attracted considerable attention for sodium-ion batteries owing to its particular three-dimensional framework and fast Na + transport channels. Moreover, its high operating voltage and excellent cycling stabil...

A lightweight YOLOv11n model with enhanced multi scale feature representation for wildfire detection

The increasing frequency and severity of wildfires pose serious threats to ecosystems, human safety, and property security. Accurate and timely detection of fire and smoke from satellite imagery is therefore essential for early warning and emergency response. However, wildfire de...

A model-based parameter optimization strategy for dual-rotating-compensator mueller matrix ellipsometers

The dual-rotating-compensator Mueller matrix ellipsometer is a vital tool for characterizing thin films and nanostructures. However, its measurement precision is highly sensitive to the system configuration parameters. Random noise generated during the modulation-demodulation pro...

Effects of wind-gathering cascade structural optimization and blade tip modification on the aeroacoustic performance of roof-mounted concentrator wind turbines

To enhance aerodynamic performance and suppress operational noise of roof-mounted concentrator wind turbines, this study proposes a synergistic scheme integrating concentrator cascade structural optimization and blade tip leading-edge perforation. First, Venturi-effect-based 3D n...

Institutional legitimacy and voluntary environmental certification: diffusion mechanisms of green factory standards in China

In the context of global sustainable development and the “dual carbon” goals, environmental protection has become a crucial issue that cannot be ignored in the economic development of various countries. In particular, the Pearl River Delta region, as an important base for China’s...

Navigating to Interact: A Dual‐Graph Framework Orchestrating Semantic Exploration and Local Positioning for Household Assisting Robots

Performing tasks for household assisting robots in complex, multi‐room environments requires embodied agents to accomplish long‐horizon cross‐room navigation and precise object interaction. However, existing approaches typically focus either on visual navigation without physical...

Physics-aligned causal inference of driving styles on electric vehicles battery aging

Abstract Lithium-ion batteries (LIBs) remain the core service life bottleneck of electric vehicles (EVs), and driving style is a critical human factor dominating EV battery degradation as assessed via aging proxy indicators and semi-empirical model predictions. Existing studies m...

Quantitative evaluation of defect parameters in magnetic flux leakage testing based on an improved magnetic dipole model and convolutional neural networks

Acquiring low-cost magnetic flux leakage (MFL) signals while accurately inverting defect geometric parameters remains a significant challenge in magnetic flux leakage non-destructive testing. To address this issue, this paper proposes a simulation-driven defect inversion framewor...

Facet‐Engineered Zn Nanosheet Arrays for High‐Energy‐Density Fiber‐Shaped Zn–Air Batteries

Fiber‐shaped zinc–air batteries (FZABs) hold great promise for wearable energy storage owing to their intrinsic safety, mechanical flexibility, and high theoretical energy density, yet their practical energy density remains fundamentally constrained by the low utilization of Zn a...

Deubiquitinase USP7 stabilizes the histone demethylase KDM5B and promotes the progression of renal fibrosis through the TSC1/mTOR axis

Abstract Ubiquitin-specific protease 7 (USP7) is a deubiquitinase that plays critical regulatory roles in multiple signaling pathways by preventing the ubiquitin-mediated degradation of its substrates. Dysregulated expression of USP7 is implicated in tumor progression; however, i...

A Direction-Aware Lightweight Network for Camera-Based Underground Mine Track Region Segmentation

Accurate localization of the visible track region is essential for perception using front-mounted cameras on underground rail-guided mine vehicles. The task is difficult because the track foreground occupies only a small image area, and its boundary appearance changes with illumi...
