Cation Diffusion‐Mediated Displaced Reaction‐Transformation in Green Steelmaking

Advanced Science, EarlyView.
The removal of O lattice atoms by environmental H2 at the surface of Fe3O4 results in Fe enrichment, driving the inward diffusion of Fe cations into the bulk. Through hopping between unoccupied and initially occupied sites, cation diffusion triggers a spatially displaced reaction‐transformation and drives subsequent dynamic phase transformations and ...

Smart Denture with Embedded Thin‐Film Temperature Sensors Patterned by Femtosecond Laser Pulse for Elderly Healthcare

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
We demonstrate the direct‐laser patterning of a gold thin film on polymethyl methacrylate to fabricate a temperature sensor for dentures. The temperature sensor‐embedded smart dentures are evaluated in an oral environment, enabling in‐situ monitoring for elderly healthcare.

A New Paradigm for Understanding the Rheology and Processability of Poly(p‐Phenylene Terephthalamide) Liquid‐Crystalline Solutions

Journal of Applied Polymer Science, EarlyView.
Kevlar is traditionally modeled as a rigid‐rod polymer, yet rheological behavior deviates from this assumption. The review introduces a novel “twist‐tie” entanglement theory for aramid polymer chains in the nematic liquid crystal state, providing a molecular explanation for deviations from rigid‐rod models. Understanding twist‐tie entanglement dynamics

Computational fluid dynamics simulations of airflow through the nasal passages of rhinolophoid bats

The Anatomical Record, EarlyView.
Abstract The nasal passages of bats that emit their echolocation call through their nostrils have adapted for sound emission as well as standard respiratory and olfactory functions. Rhinolophids, hipposiderids and rhinonycterids all use a high duty cycle (HDC) echolocation strategy.

A New Anthropomorphic Mannequin for Efficacy Evaluation of Thoracic Protective Equipment Against Blast Threats

Frontiers in Bioengineering and Biotechnology, 2022
Exposure to blast is one of the major causes of death and disability in recent military conflicts. Therefore, it is crucial to evaluate the protective capability of the ballistic-proof equipment worn by soldiers against the effects of blast overpressure (

Stretch‐shortening cycle force–time and power–time waveform analysis indicates limitations of the contralateral limb benchmark in athletes with ACL injury

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Unilateral countermovement jump (CMJsingle) testing is commonly used after anterior cruciate ligament reconstruction (ACLR) to assess stretch‐shortening cycle (SSC) function and return‐to‐sport readiness. However, the impact of ACLR on contralateral limb SSC function is poorly understood, which may impact the utility of the ...
