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.

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

Quarkonium dissociation by anisotropy [PDF]

open access: yesJournal of High Energy Physics, 2013
We compute the screening length for quarkonium mesons moving through an anisotropic, strongly coupled N=4 super Yang-Mills plasma by means of its gravity dual. We present the results for arbitrary velocities and orientations of the mesons, as well as for arbitrary values of the anisotropy.

Anisotropy of Molecules [PDF]

open access: yesNature, 1922
DIRECT evidence that the molecules of gases are not spherically symmetrical and are anisotropic in their properties is furnished by the recent experiments of Lord Rayleigh, who has shown that the light scattered by molecules is, in general, not completely polarised when observed in a direction transverse to the pencil of light traversing the gas.

Random-anisotropy-axis magnet with infinite anisotropy

open access: yesPhysical Review B, 1987
We have studied the random-axis magnet with infinite anisotropy by three methods: Cayley-tree approximation, Migdal-Kadanoff renormalization group (MKRG), and Imry-Ma scaling. In the Cayley-tree approximation, by an examination of susceptibilities, it is shown that there exists a competition between the coordination number z and the number of ...

Anisotropy in solid inflation [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2013
In the model of solid / elastic inflation, inflation is driven by a source that has the field theoretical description of a solid. To allow for prolonged slow roll inflation, the solid needs to be extremely insensitive to the spatial expansion. We point out that, because of this property, the solid is also rather inefficient in erasing anisotropic ...

Dielectric magnetochiral anisotropy

open access: yesNature Communications, 2022
AbstractThe combination of chirality and magnetism has steadily grown over the last decennia into an area of intense research. Magnetochiral anisotropy, chirality-induced spin-selectivity and helimagnetism are the most prominent phenomena resulting from this combination, touching different systems like topological (semi-)metals and insulators, quantum ...

Observation of a large-scale anisotropy in the arrival directions of cosmic rays above 8 × 1018 eV [PDF]

open access: yesScience, 2017
Cosmic rays are atomic nuclei arriving from outer space that reach the highest energies observed in nature. Clues to their origin come from studying the distribution of their arrival directions.

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 ...
