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.

Magnetic susceptibility anisotropy of myocardium imaged by cardiovascular magnetic resonance reflects the anisotropy of myocardial filament α-helix polypeptide bonds. [PDF]

open access: yes, 2015
BackgroundA key component of evaluating myocardial tissue function is the assessment of myofiber organization and structure. Studies suggest that striated muscle fibers are magnetically anisotropic, which, if measurable in the heart, may provide a tool ...

Hot Corrosion Behavior of a Novel Co-base Superalloy in Molten NaCl at 900℃

open access: yesCailiao gongcheng, 2018
Hot corrosion behavior of a new cobalt-base superalloy at 900℃ in the molten NaCl was investigated by salt-leaching method. The results show that the selective oxidation occurs at the initial stage of corrosion, and the oxidation films including Al2O3 ...

Atomic Simulations of (8,0)CNT-Graphene by SCC-DFTB Algorithm

open access: yesNanomaterials, 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

Joint anisotropy and source count constraints on the contribution of blazars to the diffuse gamma-ray background [PDF]

open access: yes, 2012
We place new constraints on the contribution of blazars to the large-scale isotropic gamma-ray background (IGRB) by jointly analyzing the measured source count distribution (logN-logS) of blazars and the measured intensity and anisotropy of the IGRB.

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.

Bubble and Skyrmion Crystals in Frustrated Magnets with Easy-Axis Anisotropy [PDF]

open access: yes, 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 ...

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 ...

Antibacterial metals and alloys for potential biomedical implants

open access: yesBioactive Materials, 2021
Metals and alloys, including stainless steel, titanium and its alloys, cobalt alloys, and other metals and alloys have been widely used clinically as implant materials, but implant-related infection or inflammation is still one of the main causes of ...

Effect of Co doping on the in-plane anisotropy in the optical spectrum of underdoped Ba(Fe1-xCox)2As2

open access: yes, 2012
We investigated the anisotropy in the in-plane optical spectra of detwinned Ba(Fe1-xCox)2As2. The optical conductivity spectrum of BaFe2As2 shows appreciable anisotropy in the magnetostructural ordered phase, whereas the dc resistivity is almost ...
