We report a method for the preparation of colloidal ZnO-diluted magnetic semiconductor quantum dots (DMS-QDs) by alkaline-activated hydrolysis and condensation of zinc acetate solutions in dimethyl sulfoxide (DMSO). Mechanistic studies reveal that Co(2+) and Ni(2+) dopants inhibit nucleation and growth of ZnO nanocrystals. In particular, dopants are quantitatively excluded from the critical nuc...

This paper provides evidence to show that in the presence of imperfect formal institutions there is both a substitutional and a complementary relationship between accounting information and reputation, an informal institution. Empirical results using a sample of family firms listed in the Chinese A-share stock market from 2004 to 2007 show that in China, where the legal environment is far from ...

In this work, by using pulsed laser deposition (PLD) method, we incorporated nitrogen into the anatase TiO2 lattice to fabricate substitutional doped with different N content and film densities. All synthesized films were characterized in depth X-ray diffraction (XRD), reflectivity (XRR), photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), atomic force (AFM) UV–vis spectroscop...

The electrical, magnetic, thermal and optical characteristics of Gallium (Ga) doped silicene are investigated using density functional theory (DFT). effect doping is studied by tuning dopant concentrations as well examining varied distances, atomic interactions for the same substitutional concentration. results indicate that Ga atoms alter band structure gap in monolayer at various concentratio...

Scalable substitutional doping of two-dimensional (2D) transition metal dichalcogenides (TMDCs) is a prerequisite to developing next-generation logic and memory devices based on 2D materials. To date, efforts are still nascent. Here, we report scalable growth vanadium (V) WSe2 at front-end-of-line (FEOL) back-end-of-line (BEOL) compatible temperatures 800 {\deg}C 400 {\deg}C, respectively. A co...

For the study of geometrical structure, stability, and electronic magnetic properties Germanium tin-doped two-dimensional hexagonal boron nitride (h-BN), First-principles calculations have been carried out. Plane-wave pseudo-potential method in association with density functional theory (DFT) framework used Quantum ESPRESSO codes has implemented to perform calculations. A 3X3 supercell size sub...

introduction: today sport is one of the important social criterion and athletes are trying to be a champion. therefore, there is an increase in misuse of doping agents especially anabolic-androgenic steroid. this study was carried out to determine the prevalence of the doping agents' abuse among male bodybuilders' and to access their knowledge about their side effects in kermanshah gymnasiums i...
