Desulfovibrio vulgaris as a model microbe for the study of corrosion under sulfate‐reducing conditions

open access: yesmLife, 2022
Corrosion of iron‐containing metals under sulfate‐reducing conditions is an economically important problem. Microbial strains now known as Desulfovibrio vulgaris served as the model microbes in many of the foundational studies that developed existing ...

Grain refinement and strength enhancement in Mg wrought alloys: A review

open access: yesJournal of Magnesium and Alloys, 2023
Low absolute strength becomes one major obstacle for the wider applications of low/no rare-earth (RE) containing Mg alloys. This review firstly demonstrates the importance of grain refinement in improving strength of Mg alloys by comprehensively ...

Improving Intermediate Temperature Plasticity of Co–Al–W–Base Superalloy: Based on Optimizing MC Carbides

open access: yesMetals, 2023
The brittleness of the new Co–Al–W–base superalloys is said to be a fatal weakness for their application in the intermediate temperature range, especially for polycrystal Co–Al–W–base superalloys.

Perpendicular magnetic anisotropy of two-dimensional Rashba ferromagnets

open access: yes, 2016
We compute the magnetocrystalline anisotropy energy within two-dimensional Rashba models. For a ferromagnetic free-electron Rashba model, the magnetic anisotropy is exactly zero regardless of the strength of the Rashba coupling, unless only the lowest ...

Evolution of Recrystallization Texture in A286 Iron-Based Superalloy Thin Plates Rolled via Various Routes

open access: yesMetals, 2023
The A286 iron-based superalloy has wide-ranging applications in replacing expensive nickel-based and cobalt-based superalloy to manufacture the turbine disk as well as the pipelines and valves of the fourth-generation supercritical water reactor (SCWR ...

Renormalization of the tunnel splitting in a rotating nanomagnet

open access: yes, 2010
We study spin tunneling in a magnetic nanoparticle with biaxial anisotropy that is free to rotate about its anisotropy axis. Exact instanton of the coupled equations of motion is found that connects degenerate classical energy minima.

Anatomy of magnetic anisotropy induced by Rashba spin-orbit interactions

open access: yes, 2018
Magnetic anisotropy controls the orientational stability and switching properties of magnetic states, and therefore plays a central role in spintronics.

Microstructure and Mechanical Property of 12Cr Oxide Dispersion Strengthened Steel

open access: yesHigh Temperature Materials and Processes, 2016
Nanostructured oxide dispersion strengthened (ODS) steels with nominal compositions (wt%): Fe-12Cr-2W-0.3Ti-0.3Y2O3 were produced by mechanical alloying and hot isostatic pressing.

Uniform Spheres of α-NaYF4:RE3+ (RE=Eu, Tb, Ce, Er, and Tm): Template-Free Synthesis, Multi-Color Photoluminescence, and Their Application in Cellular Imaging

open access: yesCrystals, 2020
Uniformly dispersed luminescent probes with a high brightness and high resolution are desired in bio imaging fields. Here, ~100 nm sized and well-dispersed spheres of RE3+ doped α-NaYF4 (rare earth (RE) = Eu, Tb, Ce, Er, and Tm) have been facile ...
