Negative‐Thermal‐Expansion Strategy Enables Hard Carbon With Tuned Heat/Strain Tolerances for Sodium Storage

ABSTRACT The thermal/stress runaways pose a risk to the safety and industrialization of sodium‐ion battery (SIB), which hence requires external management equipment. Actually, the thermal/stress generation originates from the repetitive Na + intercalation within carbon interlayer...

Thermo‐Mechanical Fatigue, Crack Evolution, and Fracture Reliability of Lightweight High‐Power‐Density Diesel Pistons: A Review

ABSTRACT The higher power density and lightweight design of diesel pistons impose severe thermo‐mechanical demands. This review summarizes research on thermo‐mechanical fatigue, crack evolution, and fracture reliability in lightweight, high‐power‐density pistons. The review exami...

Enhancing flood resilience in critical communication infrastructures: empirical analysis and software-defined architecture design

Mobile communication systems serve as a lifeline for disaster response, yet catastrophic floods—exemplified by the Beijing 23·7 and Zhengzhou 7·20 events—have exposed profound vulnerabilities that trigger cascading failures in emergency command and rescue operations. While existi...

Activated Ti surface breaking the galvanic immunity to Zn

Purpose Hybridization of dissimilar bio-metals overcomes limitations of monolithic metals, satisfying diverse clinical requirements for implants. However, galvanic corrosion remains the central challenge. This study aims to investigate the effect of Ti on the galvanic corrosion o...

Complete genome sequence of a multidrug-resistant Proteus mirabilis clinical isolate harboring 22 antimicrobial resistance genes including bla CTX-M-15

ABSTRACT Proteus mirabilis causes urinary tract infections and wound infections and frequently exhibits multidrug resistance, complicating patient treatment. Here, we describe the complete genome sequence of a multidrug-resistant P. mirabilis wound isolate from 2025, providing in...

Early weight bearing with ultrasound monitoring is associated with accelerated functional recovery after open repair of acute achilles tendon rupture: a retrospective cohort study

Optimal rehabilitation after open repair of acute Achilles tendon rupture (AATR) remains controversial. Early weight-bearing may enhance recovery, but its clinical use is limited by lack of objective criteria. This study evaluated the safety and efficacy of an ultrasound-monitore...

Construction of a Furan-Based Core–Shell APP Flame Retardant for High-Performance Polyurethane Composites

Abstract Polyurethane (PU) with both high flame retardancy and excellent mechanical performance is highly desired for cutting-edge applications. Herein, a novel furan-based core-shell flame retardant was synthesized through in situ formation of a crosslinked furfuryl alcohol-male...

Towards Building a Multi-Source Heterogeneous Knowledge Graph for Complex Material Question Answering

Large Language Models (LLMs) show considerable potential for materials-science question answering. However, LLM responses may still be affected by unsupported parametric associations, while dense Retrieval-Augmented Generation (RAG) can fragment relational evidence across text ch...

Magnetic Insights Into Heterogeneous and Nonequilibrium Electrochemical Reactions

ABSTRACT Electrochemical energy systems are governed by interfacial reactions that are spatially heterogeneous and far from equilibrium, causing deviations from ideal behavior and unexpected phenomena. Despite significant advances, conventional characterization techniques remain...

A hierarchical whole-body control framework for humanoid robots in shelf-picking

Purpose This paper aims to present a hierarchical whole-body control (H-WBC) framework for humanoid shelf-picking in structured shelf environments. The objective is to improve motion coordination, posture regulation and safe task execution for humanoid manipulation in spatially c...
