Hierarchically Rough rGO/HAp Nanocoatings on SLM Ti–6Al–4 V Implants for Enhanced Biointegration

Small, EarlyView.
This study investigates HAp/rGO bioactive coatings on Ti‐6Al‐4V fixation implants fabricated by selective laser melting with systematically varied volumetric energy density to tailor the as‐built surface state. Composite coatings were deposited by electrophoretic deposition and characterized using micro‐CT, profilometry, FESEM/EDS, and detailed XPS to ...

Bioelectronic Wearable Sensors Produced by Computerized Embroidery Using a Dual Thread Approach

Small, EarlyView.
A dual‐thread embroidered SmartBra integrates silver‐plated and conductive‐polymer (PECOTEX) threads to enable simultaneous cardiac monitoring and open‐circuit potentiometric sensing of potassium and sodium in a breast milk substitute. The wearable platform is fabricated using computerized embroidery, offering a scalable, proof‐of‐concept route toward ...

Tailoring Zn2+ Solvation for Dendrite‐Free and High‐Efficiency Aqueous Zinc Batteries

Small, EarlyView.
A ternary water–methanol–dimethyl sulfoxide hybrid electrolyte reconstructs the Zn2+ solvation sheath by reducing free water activity and promoting coordinated solvent interactions. The regulated interfacial chemistry suppresses parasitic reactions and enables dense, uniform zinc deposition, resulting in enhanced reversibility and long‐term cycling ...

Novel {Pb6} wheels based zeolite‐type metal‐organic framework for wide temperature range and high sensitivity of luminescent thermometer

Smart Molecules, EarlyView.
The expansion of {Pb6} wheels in zeolite‐type MOFs led to emission thermal quenching of 93%, relative sensitivity of 1.03% K−1 (intensity‐based) and 0.97% K−1 (lifetime‐based) in a wide temperature range of 298–423 K. Abstract The development of luminescent thermometers synchronously exhibiting high sensitivity and stability in a wide temperature range

Microstructure, Defects, and Fatigue Response of High‐Strength Tool Steels

steel research international, EarlyView.
The martensitic tool steel family is designed for use in various working environments where they are subjected to repeatedly high mechanical loads. Despite the continuous upgrade of material´s microstructures through compositional development or processing techniques, defects remain a critical factor for the tool performance by leading to fatigue ...

Toward the Application of Multiaxial Failure Criteria: Mean Stress Sensitivity of Carbide‐Rich, High‐Alloy PM‐HIP Tool Steels Under Axial and Torsional Cyclic Loading

steel research international, EarlyView.
This study quantifies axial and torsional long‐life fatigue (LLF) behavior of three carbide‐rich PM‐HIP tool steels, correlating LLF strength with intrinsic defect size and cleanliness, thereby extracting material‐specific mean stress sensitivities and Haigh diagrams.

Press Hardening for Sustainable Lightweight Chassis Design in Heavy‐Duty Vehicles: A Material Performance and Life Cycle Assessment Approach

steel research international, EarlyView.
The article explores how high‐strength steels and press hardening revolutionize lightweight chassis design for heavy‐duty vehicles. It reveals that press hardened steels combined with shot peening can cut weight by up to 34% and reduce environmental impact by 21%–32%.

Analyses of the Deformability and Chemistry of Non‐Metallic Inclusions in QT Steels With Increased Recycling‐Induced Tramp Element Content

steel research international, EarlyView.
This work uses high‐temperature dilatometry to examine how the tramp elements Cu, Ni, and Sn affect the deformability of non‐metallic inclusions and matrix in quench‐and‐temper steel. Mg‐bearing inclusions deform less than Mg‐free ones. Copper lowers formability. Nickel increases deformability.

Tailoring Microstructure and Hardness in Maraging 300 Steel via 2.4 wt.% Niobium Addition and Controlled Aging Treatments

steel research international, EarlyView.
High Nb (2.4 wt.%) addition to Maraging 300 steel drives lattice distortion and nanoscale Nb–Mo‐rich precipitation, confirmed by energy‐dispersive X‐ray spectroscopy mapping (Mo ~5.4 wt.%, Nb ~2.5 wt.%). Nanoindentation reveals strong matrix hardening (H >4.8 GPa) at 480°C aging, while 560°C induces ~1.92 vol.% reverted austenite, enabling tunable ...
