Deformable Eutectic Alloy With Near-Theoretical Yield Strength via Hierarchical Nanoscale Multiphases and Sessile Defects. [PDF]

open access: yesAdv Sci (Weinh)
A CoCrFeNiTa0.4 eutectic high‐entropy alloy achieves a near‐theoretical yield strength of 2.6 GPa with 13.6% plasticity. This breakthrough stems from a hierarchical nanostructure (FCC‐Laves lamellae with L12/D022 precipitates), which alleviates the inter‐phase modulus/hardness mismatch through synergistic strengthening and toughening, guiding the ...

Conundrums of Localized Surface Plasmon Resonance Biosensors

open access: yesSmall, EarlyView.
Localized surface plasmon resonance (LSPR) biosensing faces fundamental conundrums arising from finite field decay lengths, environmental cross‐sensitivities, and batch variability. Competing surface, bulk, and electrostatic effects can induce red or blue spectral shifts, complicating quantification, reproducibility, and interpretation in complex or ...

Pulse Electrodeposited NiFeCoMoW High‐Entropy Alloy Electrode for Efficient Alkaline Water Electrolysis

open access: yesSmall, EarlyView.
A pulse‐electrodeposited NiFeCoMoW high‐entropy alloy grown on copper foam forms a binder‐free, hierarchical electrode for alkaline water splitting. The bifunctional catalyst achieves low overpotentials for hydrogen and oxygen evolution and enables efficient two‐electrode electrolysis, delivering 1.52 V at 10 mA cm−2 and 1.83 V at 1000 mA cm−2.

Spatiotemporal Co‐Delivery of Hydrogen and Magnesium via Microneedle Patches for Neuroinflammation Modulation After Spinal Cord Injury: A Multi‐Modal In Vivo Study

open access: yesSmall, EarlyView.
A spatiotemporal co‐delivery microneedle system (MN‐Mg) is developed for spinal cord injury repair. By generating hydrogen gas and magnesium ions in situ, this dual‐engine platform effectively scavenges ROS and modulates microglial polarization via the MAPK/AP‐1 signaling axis.

Recycling End‐of‐Life Solid Oxide Cell Interconnect Assemblies into Commercial‐Grade AISI 304 Stainless Steels

open access: yessteel research international, EarlyView.
This study validates a recycling pathway for converting interconnect assemblies from end‐of‐life SOC stacks into commercial‐grade AISI 304 steels. Using scrap‐based steelmaking operations, austenitic cast steels with <4.0% δ‐ferrite are successfully produced.

Modeling the Thermal Properties of Hydrogen‐Based Direct Reduced Iron Using Computational Thermodynamics and Machine Learning

open access: yessteel research international, EarlyView.
Hydrogen‐based direct reduced iron (H‐DRI) melts differently from scrap and carbon‐bearing DRI. This work combines differential scanning calorimetry experiments, FactSage thermodynamics, and simple composition‐based regression to predict solidus, liquidus, heat capacity, and enthalpy for H‐DRI.
