Dual‐Functionality, Bio‐Friendly Artificial Muscles for Actuation and Motion Sensing in Smart Wearable Systems

open access: yesSmall, EarlyView.
This work presents a biofriendly carbon nanotube yarn artificial muscle operating either as an in‐air unipolar actuator or as a self‐powered ionotronic strain sensor. Using a non‐volatile eutectogel‐derived electrolyte, the system achieves up to 2.9% contraction and 0.5 mV/% strain sensing sensitivity.

State‐Programmable Conductive and Reactivatable Bio‐Adhesive for High‐Fidelity Epidermal Biointerfaces

open access: yesSmall, EarlyView.
A printable, reactivatable conductive adhesive (RCA) transitions from a robust, non‐tacky solid film into a soft, conformal biointerface upon solvent activation. By adapting to complex skin microtopography and hair‐covered scalp, the state‐programmable adhesive achieves strong adhesion and low interfacial impedance, enabling high‐fidelity EEG and pulse

Electroconductive MXene‐Thin‐Film‐Composite Membranes for Coupled Osmotic Concentration and PFAS Mineralization

open access: yesSmall, EarlyView.
An electroconductive MXene‐TFC membrane integrates osmotic dewatering with anodic oxidation to concentrate and mineralize PFOA at the membrane interface. The coupled AO‐PRO configuration accelerates degradation kinetics, achieves 99% rejection and up to 93% TOC removal, and lowers specific energy demand, offering a compact route for PFAS destruction ...

Influence of Viscous Dissipation on Wear Behavior and Hardness Evolution of Tool Steels in Glass‐Fiber‐Reinforced Polymer Processing

open access: yessteel research international, EarlyView.
Tool steels tested under injection molding conditions with glass‐fiber‐reinforced polymers, revealing how viscous dissipation drives hardness loss, even in PM grades. A sharp rise in wear with increasing injection volume rate and thermomechanical load uncovers striking material differences.

Side‐by‐side long‐term performance assessment of GFRP‐ and steel‐reinforced concrete bridge decks

open access: yesStructural Concrete, EarlyView.
Abstract The corrosion‐induced deterioration of steel‐reinforced bridge decks is a service life concern, especially in cold regions, where the use of deicing chemicals is common. To address this issue, glass fiber‐reinforced polymer (GFRP) reinforcement has received growing attention, owing to the GFRP's resistance to conventional corrosion.

Preparation of Hydrophilic Polysilsesquioxanes and Their Applications as Water Separation and Antifogging Coating Materials

open access: yesThe Chemical Record, EarlyView.
Hydrophilic substituents were introduced onto the silicon atoms of random polysilsesquioxanes (PSQs) to improve water permeability and absorptivity for exploring the applications of PSQ materials as heat‐ and chlorine‐resistant water desalination reverse osmosis (RO) membranes and scratch‐resistant antifogging coating materials.

Attention‐Based Spatial–Temporal Model for the Entire Indoor Space Temperature Estimation

open access: yesIEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
This study proposes a novel attention‐based spatial–temporal model for indoor temperature estimation, which integrates positional encoding and an attention mechanism with a fully connected neural network. By jointly capturing temporal dynamics and spatial correlations, the model enables high‐resolution estimation of temperature fields across the entire

Progress in bone tissue engineering biomaterials: Development, challenges, and prospects

open access: yesVIEW, EarlyView.
Scheme 1 Application of biomaterials in immunomodulation during bone tissue engineering. Abstract Bone defect repair remains a major clinical challenge in orthopedics. Over 2 million cases caused by trauma, tumors, and other factors occur annually, with large‐scale defects posing a particular bottleneck due to limited self‐healing capacity.
