Electrochemically Modified Mn₂P₄O₁₂ as an Emerging Catalyst for Oxygen Evolution Reaction

open access: yesAdvanced Materials Interfaces, EarlyView.
Mn₂P₄O₁₂ nanomaterials derived from MnO₂ nanosheets, act as pre‐catalysts and undergo in situ surface reconstruction during alkaline OER. The transformation yields MnO₂ and restructured Mn₂P₄O₁₂ phases, forming efficient active sites. This work highlights cyclotetraphosphate‐based catalysis and introduces a cost‐effective, stable material for enhanced ...

Magnetoelastic Sensing: A Study of Flexible Magnetoelastic Strain Sensors for Highly Deformed Posture Perception

open access: yesAdvanced Materials Technologies, EarlyView.
This study proposes a magnetoelastic strain sensor for highly deformed posture perception. The sensor can maintain stable sensing signal output under significant strain (200%) and at varying stretch rates (ranging from 1000 to 8000 mm min−1). The sensor design is simple and can be applied to soft robots and wearable devices.

Flexible Production of Spherical Powders of Ti‐V‐Zr‐Nb‐Mo‐Hf‐Ta‐W Refractory High‐Entropy Alloys by Plasma‐Assisted Centrifugal Atomization

open access: yesAdvanced Materials Technologies, EarlyView.
In this work, spherical powders of refractory Ti‐V‐Zr‐Nb‐Mo‐Hf‐Ta‐W high‐entropy alloys (R‐HEAs) have been fabricated in a single step by plasma‐assisted centrifugal atomization. Loss of the heaviest elements in the composition is observed only at rotational speeds higher than 13 000 rpm due to solid‐solid centrifugal separation.

Numerical and Experimental Study of High‐Speed Laser Cutting of Copper Current Collectors: Process Optimization for Quality Assessment

open access: yesAdvanced Materials Technologies, EarlyView.
This study employs a CFD model to simulate laser cutting of copper current collectors used for Li‐Ion battery production. This model predicts cut edge quality by assessing the influence of power, scanner speed, and foil thickness. Defects are classified and an optimal working area is found.

Transforming Room Acoustics with Causality‐Driven Dual‐Function Passive Metamaterials

open access: yesAdvanced Materials Technologies, Volume 10, Issue 11, June 5, 2025.
This work presents an dual acoustic metamaterial for rooms that achieves excellent broadband performance for both sound absorption and sound diffusion. This is done by using causality formulations linking the absorption of the passive system to its volume, yielding an optimal surface area ratio required for excellent sound absorption and while ...
