The present study provides evidence for the role of ferrite-grain-size distributions on the occurrence of void initiation in a low-carbon steel. Various thermomechanical treatments were undertaken to create ultrafine, bimodal and coarse distributions of ferrite grain sizes. A two-parameter characterisation of probable…
The electrical characteristics of Aluminum Electrolytic Capacitors are usually measured in frequency domain. The measured data of capacitance and dissipation or equivalent series resistance (ESR) has been treated individually for each frequency, and the “LCR” model has been developed by utilizing the measurement data…
The interface of two solids in contact introduces a thermal boundary resistance (TBR), which is challenging to measure from experiments. Besides, if the interface is reactive, it can form an intermediate recrystallized or amorphous region, and extra influencing phenomena are introduced. Reactive force field Molecular…
We consider a hybrid structure formed by graphene and an insulating antiferromagnet, separated by a dielectric of thickness up to nm. When uncoupled, both graphene and the antiferromagnetic surface host their own polariton modes coupling the electromagnetic field with plasmons in the case of graphene, and with magnons…

Lead halide perovskites, which can be grown by solution process, are very suitable for various optoelectronic applications, such as in solar cells, light-emitting diodes, lasers and photo-detectors, due to their outstanding electrical and optical properties. However, lead halide perovskites are unstable under continuo…
This article presents an investigation of the sensing properties of chemiresistors based on Cu₂O/CuO core–shell nanowires containing p–p′ heterojunctions. The nanowires were synthesized by a conventional hydrothermal method and used for the detection of ethanol and nitrogen dioxide, reducing and oxidizing agents, resp…
In blasting of soft to medium hard rock, the problem of high density resulting in excessive utilization of emulsion explosive is well known. The authors have conducted some experimental blasts to delve into the detonation behavior of conventional blasting and various other explosive consumption reduction techniques wh…
Redox-active Metal–Organic Frameworks (MOFs) are considered as promising platforms for assembling high quantities of solution-accessible molecular catalysts on conductive surfaces, toward their utilization in electrochemical solar fuel related reactions. Nevertheless, slow redox hopping-based conductivity often consti…
The structure, stability, and adsorption mechanism on the Au(111) surface of hydrophilic/hydrophobic ionic liquids (ILs) with various lengths of the alkyl chain group in the cation were investigated using first-principles approaches including electrostatic potential (ESP), electron density analysis, and dispersion-cor…
Хімічний захист рослин – це один з найпоширеніших та дієвих засобів захисту рослин. Такий метод поряд зі своєю ефективністю може бути надто небезпечним для живих організмів та екології в цілому. Відносна безпечність даного методу полягає, перш за все, у чіткому дотриманні науковообґрунтованих вимог щодо здійснення так…

Mercury ion pollution has serious harmful impact on the ecological environment and human health. It is of great significance to develop a probe with high selectivity and sensitivity that could be applied to the detection of mercury ion in water environment. In this paper, a novel excited-state intramolecular proton tr…
Microstructural changes in conventional yttria stabilized zirconia (YSZ) and multilayer Mullite-YSZ/YSZ (M-YSZ) thermal barrier coatings were compared based on high temperature isothermal oxidation at the temperatures of 1050, 1150 and 1250 °C. Both types of thermal barrier coatings were produced from commercially ava…
Although Warburgia salutaris is popular and well-known medicinal plant in southern Africa, there is still a wealth of undocumented therapeutic uses of the species within the Vhavenda ethnic group in South Africa. The literature studies confirmed that there is a sparse rather than a paucity of information about W. salu…
—Present investigation deals with the mechanical properties and microstructure of dual phase (DP) steel. Normalizing and intercritical annealing heat treatments were carried out at 900, 750, 770, and 790 ˚C and DP ferrite–martensite steel was obtained. Interaction behavior of both phases has been analyzed through tens…

This paper reports on room temperature photoluminescence (PL) studies on copper zinc sulfide (CuZnS) films that are deposited through chemical bath deposition (CBD) technique. The PL emission is a broad emission in greenish red region of the spectra. PL spectroscopy is employed as a non-destructive tool to identify co…
