Connectivity‐Dependent Mechanics of Main‐Chain Oligomers in Side‐Chain Liquid‐Crystalline Polyacrylate Networks

Journal of Polymer Science, EarlyView.
Main‐chain liquid‐crystalline oligomers are incorporated into side‐chain polyacrylate elastomers either as covalently connected strands or as non‐network‐bound, physically confined chains. Both architectures contribute to short‐time soft elasticity, but only the capped oligomer shows an additional long‐time terminal relaxation.

Stair‐Climbing Wheelchairs for Enhanced Mobility: A Comprehensive Review of Fundamental Mechanisms, Design Concepts, and Performance Analysis

Journal of Field Robotics, EarlyView.
ABSTRACT People with physical disabilities face significant mobility challenges while climbing uneven surfaces and staircases. In these circumstances, traditional wheelchairs do not provide stable, safely controlled mobility, underscoring the importance of building superior stair‐climbing wheelchairs for both medical and infrastructure purposes.

Engineering Carbon Nanotube Quantum Well Defects With Recognition Tripeptides for Optical Detection of Extracellular Vesicles in Plasma

Small, EarlyView.
A three‐residue peptide bioconjugated onto a carbon nanotube quantum defect turns the near‐infrared emission of quantum defects into a reporter of integrins on intact extracellular vesicles, directly in human plasma. The sensor reveals that healthy fibroblast vesicles carry as much RGD‐binding integrin as cancer‐derived ones, an adhesion‐associated ...

Fenestrated Microneedle Biosensor for Continuous In Vivo Lactate Monitoring in Interstitial Fluid

Small, EarlyView.
A fenestrated microneedle biosensor enables continuous transdermal monitoring of lactate in interstitial fluid while protecting the functional sensing interface during insertion into the skin. The platform delivers sensitive electrochemical lactate detection and distinguishes metabolic profiles in healthy and type 2 diabetic‐obese mice, and captures ...

Engineering metal‐organic framework‐based smart porous nanoplatforms for targeted therapy and theranostic applications

Smart Molecules, EarlyView.
MOFs offer high porosity and tunability for biomedical applications, especially in cancer therapy via ROS generation and targeted delivery. Though toxicity, stability, and scalability remain key clinical challenges. Drug loading in MOFs exceeds 60%–70% with controlled release behavior.

Tailoring Laser Powder Bed Fusion and Post‐Processing Parameters for JIS SKD61 Tool Steels: Surface Roughness, Microstructure, and Mechanical Properties

steel research international, EarlyView.
Laser powder bed fusion of JIS SKD61 tool steel is systematically optimized using a Taguchi design and ANOVA. Hatch spacing and layer thickness are identified as dominant parameters controlling surface roughness and tensile strength. Subsequent tempering at 600°C improves microstructural stability and mechanical performance, enabling high‐density SKD61

Multi‐Scale Mechanical Behavior of Additive‐Manufactured 316L Stainless Steel Processed by Severe Plastic Deformation

steel research international, EarlyView.
The multi‐scale mechanical behavior of additive‐manufactured 316L stainless steel processed by directed energy deposition and high‐pressure torsion is explored. The influence of torsional strain on strength and microstructural evolution is revealed, indicating progressive grain refinement in the ultrafine regime, reaching strength levels nearing 1800 ...
