mLife, 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 ...

Metals, 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.

Bubble and Skyrmion Crystals in Frustrated Magnets with Easy-Axis Anisotropy [PDF]
, 2016 We clarify the conditions for the emergence of multiple-${\bf Q}$ structures out of lattice and easy-axis spin anisotropy in frustrated magnets. By considering magnets whose exchange interaction has multiple global minima in momentum space, we find that ...

International Journal of Electrochemical Science, 2015 A hybrid material composed of nitrogen-doped graphene anchored with Fe2O3 was readily obtained by a facile and one-step hydrothermal method followed by assisting with microwave under mild conditions. Scanning electron microscopy and transmission electron

Phenomenological description of anisotropy effects in some ferromagnetic superconductors
, 2014 We study phenomenologically by using the previously derived Landau free energy, the role of anisotropy in ferromagnetic superconductors UGe2, URhGe, and UCoGe. The three compounds are separately discussed with the special stress on UGe2.

Atomic Simulations of (8,0)CNT-Graphene by SCC-DFTB Algorithm
Nanomaterials, 2022 Self-consistent density functional tight binding (SCC-DFTB) approaches were used to study optimized structures, energy, differential charge density, and Mülliken populations for the (8,0) carbon nanotubes (CNTs) connected to the graphene having different

Macrospin limit and configurational anisotropy in nanoscale Permalloy triangles
, 2009 In Permalloy submicron triangles, configurational anisotropy - a higher-order form of shape anisotropy - yields three equivalent easy axes, imposed by the structures' symmetry order.

Renormalization of the tunnel splitting in a rotating nanomagnet
, 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.

Microstructure and Mechanical Property of 12Cr Oxide Dispersion Strengthened Steel
High 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.
