Abstract The paper presents results of investigations on surface properties of transparent semiconducting thin films based on (Ti-Cu)oxide system prepared using multi-magnetron sputtering system. The thin films were prepared using two programmed profiles of pulse width modulation coefficient, so called V- and U-shape…
Abstract Centrifugation is used in fabricating, e.g., films with large areas and/or thicknesses of several micrometers. However, it has yet to be widely employed for chalcogenide compounds, due to their relatively weak solubility in most solvents. Determining the optimum conditions for preparing solutions of chalcogen…
Corresponding data set for Tran-SET Project No. 17CLSU08. Abstract of the final report is stated below for reference: "Reinforced Concrete (RC) structures are vital to the US’s civil infrastructure for their strength and versatility. Unfortunately, RC elements deteriorate rapidly when exposed to corrosive environments…
Abstract The adsorption and protective properties of the corrosion inhibitors SolIng IK-2, IK-3, and IK-4(A) are studied by the method of electrochemical impedance spectroscopy. It is found that these inhibitors efficiently protect against corrosion in 1 M HCl solution. The calculated degrees of surface filling indica…
Abstract In this paper, comparative studies on the structural, surface, optical, mechanical and corrosion properties of titanium dioxide (TiO 2 ) thin films deposited by continuous and sequential magnetron sputtering processes were presented. In case of continuous process, magnetron was continuously supplied with volt…
In high-efficiency power plants, some components must withstand high stress and temperature. Materials scientists manipulate alloying element composition and thermomechanical processing to design specific mechanical properties in alloys. The analyzed 8-12% Cr steel dataset, for iron base alloy compositions (>80) and p…
Typical standalone solar photovoltaic (PV) systems use battery bank as the energy storage device. The battery bank is charged by using a solar charge controller connected to a solar array. For similar PV systems, charging efficiency mostly depends on the efficiency of DC-DC converter available inside the charge contro…
This research was carried out to evaluate the influence of hooked-end steel fibers on compressive and flexural strength of concrete containing palm oil biomass clinker (POBC) as partial replacement of fine aggregates. The optimum percentage of POBC was taken as 10%, to replace natural sand. Due to the porous character…
Abstract Film samples of poly(vinylidene fluoride-trifluoroethylene) copolymer containing 2% of carbon nanotubes were synthesized. The temperatures of the ferroelectric phase transition and the value of permittivity at the frequency of 1 MHz were determined. The surface was visualized using scanning probe microscopy;…
In this study, hydrolysis of the anticancer drug trans -bis-(3-amino-flavone)dichloridoplatinum(II) ( trans - Pt(3-af) 2 Cl 2 ; TCAP) in gas and solution phases is studied. With the polarizable continuum model (PCM) model the complex computational study is performed in an aqueous solvent. Before the complex interactio…
In article number 1801954, Wallace C.H. Choy and co-workers reveal the thermionic-emission assisted electron transport mechanism theoretically and experimentally in a novel interconnecting structure of perovskite-perovskite tandem solar cells. This interconnecting layer features solvent-resistance, is free of indium t…
Abstract— Boehmite gel was prepared via hydrolysis of aluminum isopropylate in a water–alcohol solution. Electron-microscopic examination showed that the boehmite particles were highly uniform in diameter, at ~70 nm. X-ray fluorescence analysis demonstrated high purity of the material. The boehmite was heat-treated in…
The measurement of transient temperatures less than 1000 K for samples in laser-heated diamond anvil cells remains a challenge. Here we present the design and performance characteristics of a multi-channel pyrometer that works in the near-infrared from 1200 to 2000 nm. It has a relatively small footprint, is portable,…
Abstract Laminated paperboard is one of the main materials used in packaging products. The technical processes used for manufacturing such materials lead to a sepcial fiber structure that gives the material anisotropic behavior which can be observed in experiments. Two different directions can be distinguished;the in‐…
We researched the relation between deposition and ultra-thin VN films parameters. To conduct the experimental study we varied substrate temperature, Ar and N 2 partial pressures and deposition rate. The study allowed us to obtain the films with close to the bulk values transition temperatures and implement such sample…
Abstract Herein, a finite strain microscale model for magnetorheological elastomers with magnetically hard fillers is presented. Therein, the magnetic hysteresis of the particles are described by a phenomenological, thermodynamically consistent hysteresis model. To connect the microscopic fields to effective macroscop…
Sintered Fe-Cr-Mo-Si-C alloys, produced from two different pre-alloyed powders with compositions of Fe-3.0Cr-0.5Mo and Fe-1.5Cr-0.2Mo, showed a microstructure similar to that of a fully pearlitic ductile cast iron (DCI EN GJS700-2). The two sintered alloys exhibited close values of area fractions of a black particle (…
Glass samples in system (90-x)RWG–10Na 2 O–xNd 2 O 3 . The glass samples were prepared using melt quenching method. The elastic moduli were studied by measurement ultrasonic velocities using pulse echo technique. The structural properties of the glass samples were investigated using infrared absorption spectroscopy. T…
A possibility for hydrogenation of a two-phase magnesium alloy containing intermetallic compound Mg 2 Yb by hydrogen and ammonia is found to yield hydride phases MgH 2 and MgYbH 3.5 in various temperature schedules. The use of ammonia in the range 350–500°C leads to the formation of magnesium and ytterbium nitrides.
In article number 1805306, Zhang-Kai Zhou and co-workers demonstrate a coherent pixel design for metasurface printing-images, in which three optical parameters (i.e. incident wavelength, angle, and polarization) with arbitrary values can be simultaneously used to control image generation and switching. The coherent pi…
