We present a microscopic theory of the anomalous Hall effect (AHE) in metallic multiband ferromagnets, which accounts for all scattering-independent contributions, i.e., both the intrinsic and the so-called side jump. For a model of Gaussian disorder, the AHE is expressed solely in terms of the material's electronic band structure. Our theory handles systematically the interband-scattering cohe...

four different alkaline earth metal oxides i.e. mgo, cao, sro and bao were used as heterogeneous catalysts for biodiesel production from palm oil. effects of critical process variables i.e. reaction time, methanol to oil ratio and temperature were investigated. the results were then fitted to a historical design to study the analysis of variance (anova), to characterize interactions between var...

Abstract The paper presents the results of studies effect electromagnetic, ultrasonic and acid treatments on structure adsorption index alkaline-earth bentonite modified with nanoparticles silicon oxide aluminum. Studies have shown that contribute to an increase in capacity by 5, 10, 25%, respectively. Modification stabilized nanodispersed hydrosols amorphous (6-10.5 nm) crystalline boehmite (3...

Cyclic organic compounds with several ether linkages in their structure are of much concern our daily life applications. Crown ethers (CEs) generally heterocyclic and extremely versatile exhibiting higher binding affinity. In recent years, due to unique structure, crown widely used drug delivery, solvent extraction, cosmetics manufacturing, material studies, catalysis, separation, synthesis. Be...
