A line‐modulation‐based flux‐weakening control is proposed for surface‐mounted permanent‐magnet synchronous machines. To evaluate the average dc bus voltage utilisation, the maximum line‐modulation‐ratio, which cannot be >1, is defined. If the maximum line‐modulation‐ratio is equal to 1, the voltage capacity of voltag…
Corrosion of steel reinforcement is one of the important factors that are responsible for the short service life of reinforced concrete members, in marine structures like bridges, piers and jetties. This study, investigated the effectiveness of resin/exuda tes in corrosion prevention of reinforcement in reinforced con…
Abstract Dimethylsila-14-crown-5 (DMS14C5) and dimethylsila-17-crown-6 (DMS17C6) macrocyclic polyethers have been intercalated into montmorillonite layered silicates containing Li+, Na+ or K+ cations as exchangeable cations. XRD and FTIR spectroscopy offer information on the disposition of the macrocycle in the interl…
Abstract The purpose of this study is to provide scientific guidance for the morphological control of nanoparticle synthesis using the gas phase method. A universal thermodynamics model is developed to predict the morphology of nanoparticles fabricated using the inert gas condensation method. By using this model, the…
The divertor of a fusion reactor like DEMO requires materials able to withstand high heat fluxes and neutron irradiation for several years. For the water cooling concept of this essential part of the reactor, the most likely plasma facing material will be W, while the heatsink material considered is CuCrZr or an impro…
Abstract Effective prediction of springback during sheet metal forming is critically important for automotive and aerospace industries, especially when forming metals with high strength-to-weight ratio such as titanium. This requires materials mechanical data during plastic deformation and their dependencies on parame…
Orbital effects of a magnetic field in a proximitized semiconductor nanowire are studied in the context of the spatial extent of Majorana bound states. We develop an analytical model that explains the impact of concurring effects of paramagnetic coupling of the nanowire bands via the kinetic energy operator and spin-o…
A facile method is proposed to obtain modified shorn graphene oxide (DDAB-sGO) with improved dispersion in organic solvents. Didodecyl dimethylammonium bromide (DDAB)-sGO, which exhibits good dispersibility in the nonpolar solvent o -dichlorobenzene, was obtained via the sono-Fenton reaction and DDAB ionic functionali…
Dual mode index modulation-based orthogonal frequency division multiplexing (DM-OFDM) was recently proposed to enhance the spectral efficiency of the existing variants of OFDM with index modulation. In a DM-OFDM system, all subcarriers are activated and modulated by two distinct constellation diagrams. Consequently, a…
Abstract Temperature dependent charge transport properties of P3HT:PCBM bulk heterojunction are analysed by dc and ac measurements under dark conditions across a wide temperature range of 110–473 K, which includes the thermodynamic glass transition temperature ( T g ∼ 320 K) of the system. A change from Ohmic conducti…
Abstract The aim of this study was to develop macroporous mucoadhesive films from ureasil–polyether materials for future application in oral disease treatment. The films were prepared via the sol–gel route by using polyethylene oxide (PEO) and polypropylene oxide (PPO) polymers; triamcinolone was used as a model drug…
Observing cells and cell components in three dimensions at high magnification in transmission electron microscopy requires preparing serial ultrathin sections of the specimen. Although preparing serial ultrathin sections is considered to be very difficult, it is rather easy if the proper method is used. In this paper,…
Asymmetrical shear rolling with velocity asymmetry and geometry asymmetry is beneficial to enlarge deformation and refine grain size at the center of the thick plate compared to conventional symmetrical rolling. Dynamic recrystallization (DRX) plays a vital role in grain refinement during hot deformation. Finite eleme…
In-situ metallic glass matrix composites (MGMCs) are a new kind of promising structural engineering material. In this study, a comprehensive study about the corrosion behavior of in-situ Ti46Zr20V12Cu5Be17 MGMCs versus their size was conducted. It is interesting to find that the large sample exhibits a more excellent…
Aim: Development of functionalized nanocomposites containing AgNPs-PVP-Glucantime® to evaluate their leishmanicidal activity as a novel method for improving the pharmacological properties of the drug Glucantime® against extracellular promastigotes and intracellular amastigotes of Leishmania amazonensis in vitro to tre…
Autosomal dominant mutations in cullin-3 ( Cul3) cause the most severe form of familial hyperkalemic hypertension (FHHt). Cul3 mutations cause skipping of exon 9, which results in an internal deletion of 57 amino acids from the CUL3 protein (CUL3-∆9). The precise mechanism by which this altered form of CUL3 causes FHH…
Some polymers need a cross-linking agent for the controlled cross-linking process of polymers with a tendency to degradation during the radiation cross-linking process. While, on the other hand, other polymers do not need a cross-linking agent-predominantly there are cross-linking polymers. The Thermo-Plastic Elastome…
To endow valuable responsiveness to self-assemblies of Au nanoparticles (Au NPs), the magnetic Au nanoparticles (Au NPs)/C 16 H 33 (CH 3 ) 3 N + [CeCl 3 Br] − (CTACe) mixtures were first prepared by using an emulsion self-assembly of a magnetic surfactant, C 16 H 33 (CH 3 ) 3 N + [CeCl 3 Br] − . A versatile morphology…
In this work, the multiphase mathematical simulation (steel‐slag‐air) is performed in order to optimize the fluid dynamics and the homogenization temperature in an asymmetric delta‐type billet caster tundish. The performance of the tundish emulates, when a change of ladle occurs, for which are considered the losses of…
Microscopic characterization of radical states in organic light‐emitting diodes (OLEDs) during device operation is useful for elucidating the degradation mechanism because the radical formation has been considered as non‐radiative recombination centers. Electron spin resonance (ESR) spectroscopy is suitable for such c…
