Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

Advanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

High‐Resolution Corrosion Fingerprinting of Alloy Libraries via Microdroplet Spectroelectrochemistry

Advanced Engineering Materials, EarlyView.
Ionic‐liquid microdroplet spectroelectrochemistry enables stable, localized electrochemical measurements over extended timescales. By coupling impedance spectroscopy, wetting analysis, finite‐element simulations, and operando Raman spectroscopy, it disentangles geometrical and electrochemical effects, opening new opportunities for rapid corrosion ...

Hydrogen bond network disruption enables efficient direct reactive capture of CO2 from flue gas

Nature Communications
Electrochemical CO2 conversion offers a direct route to decarbonized fuels, but its deployment on industrial flue gas remains hindered by the low CO2 content, high O2 levels, and the resulting parasitic oxygen reduction. Binary solvent electrolytes offer

Hydrogen-bonded organic framework-lithium salt array for rapid lithium ion transport in all-solid-state lithium battery

Nano Research
Hydrogen-bonded organic frameworks (HOFs) have recently emerged as attractive candidates for solid-state electrolytes (SSEs) due to their structurally ordered pores, tunable chemical structures, and solution processability. However, direct application of

Superlubricity and Corrosion Inhibition Properties of Solvate Ionic Liquids in Hybrid Carbon Fiber Reinforced Plastic–Steel Interfaces

Advanced Engineering Materials, EarlyView.
Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

Crystal‐amorphous interface synergy in Ni/CrV‐mixed metal oxide: A strategy for rapid hydrogen uptake/release in magnesium hydride

Journal of Magnesium and Alloys
Optimizing the kinetics and lowering the ab/dehydrogenation temperature of magnesium hydride (MgH2) are crucial for hydrogen storage applications. The synergy among multi-metals (such as Ni, Cr, Fe, Cu, etc.) can reduce the ab/dehydrogenation activation ...

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

Advanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).

Environmental Contributions to Proton Sharing in Protein Low-Barrier Hydrogen Bonds

Biochemistry
Abstract Hydrogen bonds (H-bonds) are central to biomolecular structure and dynamics. Although H-bonds are typically characterized by well-defined proton positions, proton delocalization can play a key role in facilitating enzyme catalysis and allostery in some systems.
