SiO2 is the major mineral substance in the upper mantle of the earth. Therefore, studies of the silica-coated materials under high-pressure are essential to explore the physical and chemical properties of the upper mantle. The silica-confined CsPbBr3 nanocrystals (NCs) have recently attracted much attention because of…
Abstract The effects of post‐plasma exposure to deionized water treated by argon–water plasma and to direct plasma treatment of bacteria in a liquid solution of a strain of Escherichia coli, which was independently evolved to resist the bactericidal effects of hydrogen peroxide, were determined. The hydrogen peroxide…
This paper describes a novel strategy for the hemocompatibility improvement of poly(ethylene-co-vinyl alcohol) (EVAL) membranes by incorporation of a naturally occurring zwitterion, glycine. Crystalline glycine was directly integrated to the EVAL fibers via electrospinning. The membranes were characterized by Attenuat…
In this study, the nanophase ZrCr2 intermetallic compound was produced by the mechanical alloying (MA) and subsequent heat treatment. The phase transformations, crystallite size, lattice strain, and stored energy were studied at different milling times. The results indicated that MA caused to form a nanocomposite of t…
Abstract To understand the effect of the in situ carbon deposition and permeation process on cobalt-catalyzed heterogeneous reactions, the thermodynamics and kinetics of the carburization process of ten different surfaces of hexagonal close-packed (hcp) and face-centered cubic (fcc) Co and the resulting evolution of c…
Recently, nanosized metal oxides play an essential role in the photocatalytic system due to their ability to create charge carriers during the light irradiation. Metal oxide nanoparticles display excellent light absorption properties, outstanding charge transport characteristics, which are suitable in the photocatalyt…
Despite extensive studies, the exact mechanism of magnetoelastic coupling in hexagonal rare-earth manganite $R{\mathrm{MnO}}_{3}$ still remains under debate. Using inelastic x-ray scattering, we have measured the lattice vibrations of hexagonal manganite $R{\mathrm{MnO}}_{3}$ over a wide momentum-energy space to ident…
The twist mechanism of the fiber strand in the condensing zone in compact spinning is complex. This paper proposes a dynamic model to evaluate the additional twist of the fiber strands. Based on the flow simulation in the condensing zone, the fiber trajectory in the suction slot was simulated and obtained. Several spi…
Flexible and low‐power consuming integrated circuits are some of the basic requirements for smart wearable devices. High mobility solution‐processed organic field‐effect transistors (OFETs) have the potential to make a big impact in printed electronic circuits, but their overall performance is currently limited by unu…
In this work, a simple method for producing Perovskite solar cells [PSCs] by recycling automobile batteries is used. Trying to get rid of some structures or materials which are harm to the environment (i.e. recycled car batteries) by using lead [Pb] sheets from those battery. Also, by reusing car batteries we will avo…
Abstract The complex investigation of the crystal, diffusion processes, and electrical conductivity of FexCo100−x (0 < x < 100) film alloys and FexCo100−x/Cu/FexCo100−x/Sub three‐layer films with a ferromagnetic layer thickness dF = 20–50 nm and a nonmagnetic layer thickness dN = 2–30 nm has been carried out. For both…
INTRODUCTION: Recent studies have shown an increasing number of overweight and obese members serving in many armies. Overweight and obesity can be estimated using either body mass index or waist circumference measures. The aim of this research was to estimate the proportion of the Australian Army considered to be over…
In order to deal with the problem that electronic device can be affected by electromagnetic interference from external environment, this paper studied the influence of the proposed rectangular metallic enclosures to achieve effective electromagnetic shielding based on finite-integration technique. A three-dimensional…
This article reports a study to identify optimal synthesis parameters for a pure boron precursor prepared following a patented process developed at CNR-SPIN laboratories, performed in the framework of a collaboration between CNR-SPIN and CERN. Boron is a precursor that plays a crucial role in the MgB2wire manufacturin…
Na doping is introduced to improve the electrochemical properties of Li1.2Mn0.6Ni0.2O2 cathode material, which is synthesized by sol–gel method. The effect of Na doping on the morphological, structural and electrochemical properties was systematically studied and analyzed. These results illustrate that lattice layer s…
Rolling element bearings are not only one of the most common parts in rotating machinery, but also one of the most frequent reasons for unplanned shutdowns of the mechanical system. The health state of rotating bearings is therefore significant to the safety in production, which involves the techniques for feature ext…
In an effort to develop a biodegradable blend that could withstand arid environmental conditions; and standardise the use of biodegradable plastic films originating from hydro-biodegradable blends, this project was initiated by the Kuwait Institute for scientific Research.In this work, linear low-density polyethylene…
The study attempts to assess the quality of various types of samples used in the adhesive joint testing. One great weakness of the scientific research conducted on this type of joints is that the published papers generally do not include an analysis of the samples quality. Although the standards define the tolerances…
Abstract Heavily cross-linked epoxy was characterized under different types of loading. The scope of work involves detailed testing procedures utilizing high-precision digital image correlation (DIC) system for all strain measurements. Fractographic analyses using scanning electron microscopy (SEM) were also provided.…
We fabricate vertical $\mathrm{Nb}/{\mathrm{Ti}\mathrm{O}}_{x}/\mathrm{Nb}$ Josephson junctions where the ${\mathrm{Ti}\mathrm{O}}_{x}$ layer is mostly metallic but has a high-resistance interface with the top $\mathrm{Nb}$ electrode. Thus, the junctions are in essence of the superconductor--insulator--normal-metal--s…
