Hydrogen Analyses of FSW Cu‐OFP Tested Under Creep Conditions in Sulphide Containing Environment

Materials and Corrosion, EarlyView.
Friction stir welded Cu‐OFP exhibits elevated creep rates in sulphide‐containing aqueous environments, with creep increasing as sulphide concentration rises. Hydrogen measurements indicate that sulphide exposure does not increase hydrogen content. ABSTRACT Friction stir welded oxygen‐free phosphorus‐doped copper (FSW Cu‐OFP) is a candidate material for

New Insights About the Role of Sn‐Rich and Pb‐Rich Phases Over the Corrosion Mechanism of Low‐Tin Quaternary Bronze Alloys Under Sulfur‐Containing Conditions

Materials and Corrosion, EarlyView.
A mechanistic proposal for the initial steps of quaternary bronze corrosion in media containing sulfate was described. The process is driven by microgalvanic effects along the microstructure, generating anodic sites over lead and tin rich phases and cathodic sites onto Cu‐rich phases.

Wet‐Transferred MoS2 on Passivated InP: A Van der Waals Heterostructure for Advanced Optoelectronic Applications

physica status solidi (RRL) – Rapid Research Letters, Volume 19, Issue 5, May 2025.
This study presents a photodetector based on atomically thin MoS2 on an InP substrate, forming an n‐MoS2/p‐InP type‐II staggered heterojunction. The device exhibits excellent rectifying properties with an ideality factor of 1.57 and achieves a peak photoresponsivity of 960 mA W−1, while MoS2 provides stable passivation for InP. III–V semiconductors are

Thermal Instability Pathways of Aluminum‐Based Nanocomposites: The Role of Alloying‐Element‐Driven Precipitation and Amorphous Interlayers

Small, EarlyView.
Thermal instability mechanisms governing novel Al‐based PVD/ALD nanocomposites are uncovered through synchrotron XRD, STEM, APT, and micromechanical testing. Temperature‐dependent crystallite evolution reveals a defined stability window before degradation dominates, offering new insight into the design of thermally robust, functional Al‐based ...
