Peaking and hollowness of low-Z impurity profiles: an interplay between ITG and TEM induced turbulent transport

open access: yesNuclear Fusion, 2023
The transport of low-Z impurities in fusion plasmas is dominated, in many regimes of interest, by ion temperature gradient (ITG) and trapped electron mode (TEM) turbulence. We use a statistical test-particle approach to analyze the effects of these drift

Effects of ultrasonic treatment on aqueous suspensions of diamond nanopowders

open access: yesХімія, фізика та технологія поверхні, 2023
It has been found that ultrasonic treatment of diamond nanopowders contributes to surface cleaning due to the removal of non-diamond carbon and impurities from the surface boundary of nanodiamond grains (from 0.4 and 0.32 % for ASUD-99 and 0.67 and 0.55

Impurities in UBe 13

open access: yesJournal of Magnetism and Magnetic Materials, 1987
Des impuretes de gadolinium dans UBe 13 abaissent la temperature de transition supraconductrice avec un taux initial de −0,40 K/% tandis que pour Th 0,029 U 0,971 Be 13 , le taux initial est seulement −0,19 K/%. Ceci suggere l'existence de deux etats supraconducteurs differents.

Enantio- and Chemo-Selective HPLC Analysis of Silodosin on an Amylose-Based Chiral Stationary Phase

open access: yesMolecules
A direct enantio- and chemo-selective high-performance liquid chromatographic method was developed for determining the enantiomeric impurity of the chiral active pharmaceutical ingredient silodosin. The simultaneous separation of enantiomers of silodosin

Transversal magnetoresistance in Weyl semimetals

open access: yes, 2015
We explore theoretically the magnetoresistvity of three-dimensional Weyl and Dirac semimetals in transversal magnetic fields within two alternative models of disorder: (i) short-range impurities and (ii) charged (Coulomb) impurities.

Quasiparticle scattering in two dimensional helical liquid

open access: yes, 2009
We study the quasiparticle interference (QPI) patterns caused by scattering off nonmagnetic, magnetic point impurities, and edge impurities, separately, in a two dimensional helical liquid, which describes the surface states of a topological insulator ...

Random Magnetic Impurities and the ? Impurity Problem [PDF]

open access: yesJournal de Physique I, 1996
One considers the effect of disorder on the 2-dimensional density of states of an electron of charge e in a constant magnetic field superposed onto a Poissonnian random distribution of point vortices carrying a flux φ(α= e φ/2π is the dimensionless coupling constant).

New mechanism for impurity-induced step bunching

open access: yes, 2002
Codeposition of impurities during the growth of a vicinal surface leads to an impurity concentration gradient on the terraces, which induces corresponding gradients in the mobility and the chemical potential of the adatoms.
