Goodenough-Kanamori (GK) criteria have provided a significant contribution to our understanding of the importance of the symmetry and the electron orbital characteristics in the development of the magnetic superexchange coupling [antiferromagnetic (AFM) or ferromagnetic (FM)] applied primarily to systems with bond ang…
Combustion of South African discard ultra-fine coal (i.e. coal dust), charcoal, microalgae biomass, and composites of the three under air were studied. The study involves to find out the effect of Scenedesmus microalgae biomass on the comprehensive combustion characteristics of the ultra-fines. Coal dust is considered…
Mullite brick is one of the most extensively utilized blast furnace hearth lining materials that feature several advantageous properties. In this study, the microstructure and physical properties of a mullite brick under different thermal treatment temperatures were investigated. The results showed that the temperatur…
Reactions of copper(II) nitrate trihydrate with 4,4′-bipyridine (bipy) and isomeric amino acids (aa) l -leucine or l -isoleucine were investigated under different solution-based and mechanochemical synthetic procedures. Four different, but isoreticular two-dimensional coordination polymers of the general formula [Cu 2…
Abstract Glassy polymers are often used for gas separations because of their high selectivity. Although the dual‐mode permeation model correctly fits their sorption and permeation isotherms, its physical interpretation is disputed, and it does not describe permeation far from steady state, a condition expected when se…
This paper looks at the structure and properties of the high-strength light Al – Mg – Sc alloy 1580 resultant from the application of plasma welding. It was found that by-layer plasma welding with reverse polarity current ensures the absence of internal defects alongside with high strength, ductility and plasticity in…
We analyze the evolution of the exciton recombination energy ${E}_{\mathrm{PL}}$ and its pressure coefficient $d{E}_{\mathrm{PL}}/dp$, with the laser power density (LPD) exciting excitonic photoluminescence. Two $\mathrm{I}{\mathrm{n}}_{0.17}\mathrm{G}{\mathrm{a}}_{0.83}\mathrm{N}/\mathrm{GaN}$ quantum well (QW) struc…
Abstract This study addresses the dielectric performance of nonpolar hydrocarbon liquids and mineral oils under positive polarity stress. It is of interest to improve knowledge on how functional properties of dielectric liquids vary, as new brands arrive in the market, and existing standards are unsuited for documenti…
The geometry of rails and armature is one of the most important parameters considered while designing a railgun. Optimized designs reduce the unnecessary loss of energy in the railgun, thus imparting higher kinetic energy to the projectile. This article proposes a new filleted and tapered rail geometry for a railgun a…
In this study, we synthesize glass-ceramics of the new Na 1+ x Ge 2 (SiO 4 ) x (PO 4 ) 3– x NASICON (Na super-ionic conductor) series to evaluate the effect of Si 4+ /P 5+ substitution on the structural, microstructural, and electrical properties of the NaGe 2 (PO 4 ) 3 system. From X-ray diffraction, the presence of…
This article is concerned with the calculation of the corona current-voltage characteristics of a unipolar high-voltage direct current (HVDC) transmission line with a single conductor stretched above the ground plane. In light of justified assumptions, the corona charge density around the conductor surface is obtained…
Florida Department of Transportation uses the 1993 AASHTO guide to conduct new and rehabilitation designs for all the state’s flexible pavements. Based on previous experience, a structural layer coefficient of 0.44 was found to be well representative of the department’s conventional polymer-modified (PMA) asphalt conc…
Diethylhexyl phthalate (DEHP) is a common plasticizer in industrial production. Recently, environmental problems caused by microplastics have drawn wide attention. As the microplastics have a large specific surface area, the release rate of the plasticizer from the microplastics to the environment is accelerated. The…
Abstract An Er 2 O 3 capped SnO 2 nanostructure (NS) based memory device was synthesized on Si substrate by glancing angle deposition technique. Field emission scanning electron microscopy and transmission electron microscopy were used to verify the formation of the Er 2 O 3 capped SnO 2 NS. The Er 2 O 3 capped SnO 2…
At present, seeking an effective dressing for wound regeneration has drawn considerable interest. In this paper, a novel agarose-grafting-hyaluronan (Ag-g-HA) scaffold was synthesized for rapid wound healing. Elemental analysis results showed that the HA grafting rate of Ag-g-HA was ∼69%. Ag-g-HA remained bioactive to…
A simple, facile and cost-effective nanostructuring technique is proposed to construct a photoelectrochemical (PEC) sensor via the solution-based hydrothermal growth of a TiO2nanobrush (TiO2NB). It is demonstrated that the control of the TiO2seed solution ratio, process temperature and duration significantly contribut…
Abstract Dynamical hysteresis in thin film ferroelectrics (FE) is modeled by the multi-domain time-dependent Landau–Khalatnikov theory based on nucleation limited switching. Thin film ferroelectrics are treated as an ensemble of elementary regions characterized by independent coercive voltage and permanent polarizatio…
Iron-based superconductor (IBS) is expected to be the next generation high temperature superconductor with their potential good properties for the high-field application. This study focus on exploration of the characteristics of IBS coils at high field and development of the IBS coil fabrication technology. A series o…
This paper provides a complete overview of the applicability of the Equivalent Material Concept in conjunction with the Average Strain Energy Density criterion, to provide predictions of fracture loads in structural materials containing U-notches. The Average Strain Density Criterion (ASED) has a linear-elastic nature…
The laser processing of the titania nanotubes has been investigated in terms of morphology, structure, and optical properties of the obtained material. The length of the nanotubes and crystallinity, as well as the atmosphere of the laser treatment, were taken into account. The degree of changes of the initial geometry…
