Chemical Mediation Mechanism Decouples Solid State Kinetics for High‐Power Aqueous Zn‐Co Batteries

ABSTRACT Solid state conversion electrodes are promising for aqueous energy storage but are frequently constrained by sluggish interfacial kinetics, leading to a persistent energy‐power trade‐off and underutilized capacity at high rates. Here we propose a chemical mediation strat...

Experimental study of the startup and heat-transfer performance of a novel two-phase closed thermosyphon with an internal phase-separation structure

Two-phase closed thermosyphons (TPCTs) are widely used as active cooling devices in permafrost engineering. Countercurrent transport of rising gas and returning liquid through a shared flow channel can impede working-medium circulation and constrain heat-transfer performance. Thi...

Mechanistic Insights Into Anionic Doping in O3‑Type Na(NiFeMn) 1/3 O 2 Cathode

ABSTRACT The lack of mechanistic guidelines hinders rational anionic doping in layered oxide cathodes for sodium‐ion batteries (SIBs). Using O3‐type Na(NiFeMn) 1/3 O 2 as a model and combining experiments with density functional theory (DFT) calculations, we reveal that doping ef...

Microstructural evolution of SIMP steel during martensitic transformation

SIMP steel, a reduced activation ferritic/martensitic heat–resistant steel, is a promising candidate for structural applications in future nuclear fusion reactors. Understanding the evolution of microstructure in SIMP steel is of practical importance for improving the structural...

A Lithium-Ion Battery Remaining Useful Life Prediction Framework Based on Mode Decomposition and CNN-TimeXer

Remaining useful life (RUL) prediction is essential for lithium-ion battery health management, yet accurate prognosis remains difficult because battery degradation trajectories are strongly non-stationary and often contain mixed-scale fluctuations together with local regeneration...

Dynamic Modeling and Self-Tuning Fuzzy Skyhook Control of a Metro Vehicle with a Flexible Carbody and Semi-Active Suspension

Lightweight metro carbodies may exhibit elastic modes within ride-comfort-relevant frequency bands, limiting semi-active suspension controllers tuned offline for nominal conditions. This study proposes a skyhook-based parameter self-tuning fuzzy control (PSTFC) strategy for later...

Alfalfa-winter wheat rotations stabilize yields and maintain soil water sustainability under precipitation variability

Global climate change caused variation in precipitation patterns has become a threat for food security, especially for semi-arid rainfed farming system, i.e., the Loess Plateau. Whether short-term alfalfa-winter wheat rotations could serve as sustainable alternatives to winter wh...

Catholyte‐Free Composite Cathodes Break the Energy Density Barrier of All‐Solid‐State Lithium Batteries

ABSTRACT The gravimetric and volumetric energy densities of 500 Wh kg –1 and 1000 Wh L –1 are considered as the “holy grail” target values for the development of all‐solid‐state lithium pouch batteries. However, the substantial amount of non‐energy‐providing deformable catholytes...

An interpretable frequency-domain matrix rank transformation and time-domain spatial graph attention enhancement network for rolling bearing fault diagnosis under strong noise environment

Extracting weak fault features obscured by environmental noise is a critical challenge. However, existing fault feature enhancement methods ignore the low-rank distribution of feature correlation structures, making it difficult to effectively extract critical fault information. T...
