Strain Engineering of Magnetic Anisotropy In article number 2101034, Hiroshige Onoda, Hideto Yanagihara, and co-workers demonstrate that the strain engineering technique is a promising way to induce large magnetic anisotropy without using heavy metals or rare earth elements. The spins (red arrows) Co ions (light blue) on octahedral sublattice spinel structure change their preferred direction in...

Cobalt blue pigments, which mainly comprise CoAl2O4, are widely synthesized as nano-scale particles using the coprecipitation method. Such ultrafine powders necessary for ceramics industry because of their significant effect on color glaze and bulk tiles. In this paper, cobalt pigments have been prepared method then subjected to supercritical fluid drying. The differences in physicochemical opt...

the structural and electrical properties of polyaniline-cobalt sulphate nanocomposite prepared by chemical method.polyaniline-cobalt sulphate nanocomposites were synthesized by the cobalt sulphate and ammonium persulphate and aniline.this paper reports on chemical technique using for synthesis of cobalt nanoparticles in the composite bridge is aniline. electrical conductivity of polyaniline wit...

In this article, we report a facile precursor pyrolysis by sol-gel method to prepare spinel-type Cobalt-substituted zinc aluminate nanoparticles (Zn1–xCoxAl2O4, 0 ? x 1). The relationship between the degree of crystallinity and optical properties under effect calcination temperature was investigated. synthesised powders were characterized means X-ray diffraction (XRD), Thermogravimetry Differen...

Abstract In this present study, a novel method to fabricate bimetallic Fe-Co catalyst supported on waste silica was investigated for the photo-Fenton-like (PFL) degradation of Methylene Blue (MB) dye. The uniqueness work is preparation via fluidized-bed crystallization (FBC) process. Under optimum conditions initial pH 3.0, 3.0 mM H 2 O , and 1.0 g L -1 FBC-derived Fe-Co/SiO (fFCS), maximum res...

In the rosy mutant of Drosophila melanogaster, two types of autofluorescent cytoplasmic inclusions are found in the cells of the posterior region of the fatbody at the prepupal stage. Bright yellow autofluorescent granules accumulating within larger inclusions clearly demarcate this area of the fatbody which also contains cobalt blue fluorescent globular material. Such inclusions were not noted...
