Abstract A full factorial central composite design (CCD) method was used to design the experiments for extractive desulphurization of straight run gas oil (SRGO) containing 0.013 g/g (1.3 wt%) sulphur in a packed bed extractor using N‐N‐dimethyl formamide (DMF) as solvent. The operational parameters, namely water conc…

In this note we summarize our recent results for the temperature dependence of transport coefficients of metallic films in the presence of spin-orbit coupling. Our focus is on (i) the spin Nernst and the thermal Edelstein effects, and (ii) the phonon skew scattering contribution to the spin Hall conductivity, which is…
Изотермическое мартенситное превращение в инструментальных сталях X153CrMoV12 и X220CrMoV13-4 и карбидообразование при последующем отпуске изучено с помощью мёссбауэровской спектроскопии, рентгеноструктурного анализа, механической спектроскопии и трансмиссионной электронной микроскопии. Установлено, что мартенситное п…
A new type of seed/catalyst-free and selective-growth process is developed for in situ grown vertically-aligned ZnO nanorods on the reduced graphene oxide (rGO) nanosheets. The dense and single-crystalline ZnO nanorods have been successfully grow on rGO nanosheets with the position- and size-controlled. The effect of…
Cone defect in rolls may be caused by bad grinding. Cone defect leads to shape defect in unilateral waves of the finished strip. By using a six-high mill as example and by considering the features of the devices and technology, an influence model of roll with cone defect and a suitable shape control technology of a si…
Control of olefin geometry has long proved a challenge in the field of Ru-catalyzed olefin metathesis. Through an understanding of the reaction mechanism, key factors that govern cis–trans selectivity in cross-metathesis applications are identified. These factors are illustrated in the relationship between ligand envi…

In this study, composites of graphite oxide (GO) in poly(methyl methacrylate) (PMMA) were obtained.Obtaining of graphite oxide was performed by two potential methods by literature: modified Hummers method and Staudenmaier method; Then, a secondary GOs obtained heat treatment step -at 1000° C -was added in order to exp…
Multiferroics (MF) have attracted much research attention due to the coexistence of ferroelectric and magnetic ordering as well as magnetoelectric (ME) coupling.At present there are very few room temperature single phase MF except BiFeO 3 .Multiferroic properties of Aurivillius compound Bi 5 FeTi 3 O 15 were reported…
AbstractThe work done trough this PhD deals with cationic and anionic substitution of LaFeO3 thin films deposited by reactive magnetron sputtering (co-sputtering of two targets in Ar+O2 mixture). The first part of the word is devoted to substitution of lanthanum by smaller rare earth, Praseodymium, Neodymium, and Sama…
Vernonia mespilifolia is widely used in folk medicine in the Eastern Cape Province, South Africa. The aim of this study was to evaluate the biological activity of the acetone, aqueous and ethanol extracts of Vernonia mespilifolia using brine shrimp hatchability and lethality assay. The result showed hatching success i…
An electromagnetic material is categorized by its constitutional parameters, permittivity ε and permeability μ. A double-positive (DPS) material is defined as a right-handed (RH) material. The phase constant of wave propagation within the RH material exhibits a positive value. A double-negative (DNG) material is defin…
The temperature evolution of GdFeCo electrons following optical heating plays\na key role in all optical switching of GdFeCo and is primarily governed by the\nstrength of coupling between electrons and phonons. Typically, the strength of\nelectron-phonon coupling in a metal is deduced by monitoring changes in\nreflect…
Biodegradable material such as poly(lactic acid) (PLA) can be generated with great control of polymer molecular weight and dispersity using a large range of metal-based catalysts. PLA is generated from the ring-opening polymerization of cyclic ester lactide, either biologically derived L-lactide or racemic lactide, us…
In this paper we consider the branched transportation problem in 2D associated with a cost per unit length of the form $1 + αm$ where $m$ denotes the amount of transported mass and $α> 0$ is a fixed parameter (notice that the limit case $α= 0$ corresponds to the classical Steiner problem). Motivated by the numerical a…
Granular materials are ubiquitous in nature and technology. Nevertheless, no macroscopic equation for granular materials is known. The discrete element method (DEM) has been widely used to simulate complex behavior of granular materials without constitutive laws. It has become increasingly clear that the dynamics of n…
Basic and advanced concepts of ligand design in modern lanthanide non-aqueous chemistry are considered to rationalize progress in this field in the last 50 years. Major advances are illustrated with selected examples, which are divided into C-, N- and P-donor ligands. These landmark results include the stabilization o…
