Simultaneous improvement of mechanical and corrosion performance of low carbon steel by deformation spheroidization treatment in simulated cargo oil tank

Journal of Materials Research and Technology
The contradiction between mechanical properties and corrosion resistance in low-carbon ship plate steel poses a significant challenge for material design, particularly in cargo oil tank (COT) environments.

Surface Defects Control Bulk Carrier Densities in Polycrystalline Pb‐Halide Perovskites

Advanced Materials, Volume 36, Issue 50, December 12, 2024.
Doping, the controlled addition of imperfections or impurities to a material, is crucial for semiconductors. This study shows that for Halide Perovskites, which have (very) low (intrinsic) defect densities because of effective self‐healing and defect tolerance, the title's statement holds in an unprecedented fashion.

Limitations of Hydrogen Detection After 150 Years of Research on Hydrogen Embrittlement

Advanced Engineering Materials, Volume 26, Issue 19, October 2024.
This article reviews the phenomenon of hydrogen embrittlement in metallurgy, tracing its historical origins and examining experimental limitations in detecting hydrogen at nanoatomic scales. It evaluates theoretical models and proposes that further development of experimental science is needed to either validate or disprove current HE theories ...

Kelvin force microscopy of polymer and small molecule thin-film transistors

, 2011
By their nature, scanning probe microscopy (SPM) measurements are ideally suited to the study of organic thin-film transistors (TFTs). In Chapter 3 surface potential measurements are made on TFTs made from the polymer pBTTT.

2D Reconfigurable Memory Device Enabled by Defect Engineering for Multifunctional Neuromorphic Computing

Advanced Materials, Volume 36, Issue 35, August 28, 2024.
An innovative reconfigurable memory device (RMD) based on MoS2/CuInP2S6 heterostructure enabled by defect engineering of ferroelectric CuInP2S6 nanosheet is developed. In memory mode, the RMD can diagnose ophthalmic disease by segmenting vasculature within biological retinas.

Corrosion behavior of plasma-nitrided TC6 titanium alloy in marine atmosphere: Experiments and first-principles calculations

Journal of Materials Research and Technology
Plasma nitriding is a surface-modification technique used to improve the surface hardness and wear resistance of titanium alloys, while its influence on corrosion behavior depends strongly on the structure and integrity of the nitrided layer.
