Epitaxial Fe(Se,Te) thin films were prepared by pulsed laser deposition on (La0.18Sr0.82)(Al0.59Ta0.41)O3 (LSAT), CaF2-buffered LSAT and bare CaF2 substrates, which exhibit an almost identical in-plane lattice parameter. The composition of all Fe(Se,Te) films were determined to be FeSe0.7Te0.3 by energy dispersive X-r…
In the present study, various Higher-order Shear Deformation beam Theories (HSDTs) are applied in order to achieve the exact analytical solution to bending, buckling, and free vibration of Functionally Graded (FG) nanobeam lying on the Winkler and Pasternak elastic foundations. HSDTs are those in which the eff ect of…
There are many examples of organic coatings used for corrosion protection. In particular, hydrophobic and super-hydrophobic coatings are shown to give good protection because of their enhanced ability to slow down transport of water and ions through the coating. The purpose of this research is to develop water repelle…
We report the direct measurements of conductivity and mobility in millimeter-sized single-crystalline graphene on SiO 2 /Si via van der Pauw geometry by using a home-designed four-probe scanning tunneling microscope (4P-STM). The gate-tunable conductivity and mobility are extracted from standard van der Pauw resistanc…
Anionic polymerization of propylene oxide was carried out in the presence of two groups of potassium salts activated 18-crown-6 (18C6), e.g. alkoxide salts (CH 3 OK, i -PrOK, t -BuOK, CH 3 OCH 2 CH(CH 3 )OK, KCH 2 O) and other salts (CbK, Ph 3 CK, Ph 2 PK, Ph 3 HBK, KK, KH, and [(CH 3 ) 3 Si] 2 NK) in THF at room temp…
The decomposition products of SF6partial discharge (PD) were experimented to detect PD fault in the gas chamber of SF6gas insulated ring network cabinet. The SF6decomposition products and the decomposition characteristics of typical defects (i.e., metal protrusion and metal particle) were investigated. Two models of t…
The work contains the results of studies of a promising composite material of Sr 2 Fe 1.5 Mo 0.5 O 6 + Ce 0.8 Sm 0.2 O 1.9 for electrodes of symmetrical solid oxide fuel cells. It is shown that conductivity of the composite at 800°C is about 10 and 15 S/cm, for air and humid hydrogen, respectively, and polarization re…
A facile one-step approach to synthesize various phase-separated porous, raspberry-like, flower-like, core–shell and anomalous nanoparticles and nanocapsules via 1,1-diphenylethene (DPE) controlled soap-free emulsion copolymerization of styrene (S) with glycidyl methacrylate (GMA), or acrylic acid (AA) is reported. By…
Abstract We present an evaluation of the hardness and Young’s modulus properties of medium pressure sputtered molybdenum disulfide (MoS 2 ) thin films by applying nano-indentation with continuous stiffness method combined with microstructure analysis using small angle x-ray diffraction, Raman, and an electron microsco…
Galvanic corrosion between law alloy steel and copper couple in 4 % NaCl solution was studied and the effect of some variable were investigated. The effect of area ratio, temperature and rotational speed through the electrolyte have been investigated. An increase in galvanic current was observed when we increased the…
Рассмотрено влияние содержания и химической природы исходных компонентов на термостойкость, воспламеняемость и дымообразующую способность композиционных материалов на основе эпоксидных олигомеров. Установлено, что фосфатные пластификаторы практически не влияют на горючесть эпоксидных полимеров, но снижают их дымообраз…
Revealing the interaction mechanism of cellulose I can help us to understand dissolution and modification mechanisms of cellulose fiber. In this paper, molecular dynamics simulation was used to analyze different interaction of cellulose I. We found that the total interaction of Van der Waals, electrostatic and solvati…
Abstract The elastomeric anti-trauma pad (EA-TP) based on shear thickening fluid (STF) has been developed. Dynamic oscillatory shear experiment was conducted at constant strain amplitude of 5%. STF composed of 25% of volume fraction of 7 nm Fumed Silica, dispersed in polypropylene glycol with molar mass 400 gmol −1 sh…
This investigation was conducted to study on the effect of shot blasting on the case depth of boride layers produced and microhardness after performing paste boronizing on 316L stainless steel. 250 micron diameter of glass beads had been used in the process of shot blasting with variation in the blasting pressure. Pas…
In the present study, the population status on Indopiptadenia oudhensis (Brandis) was recored in the Champawat. District to know the present regeneration status. The population survey was carried out and reported here with photograph and taxonomic decription.
This paper is aimed at the analysis of partial discharges (PD) that occur at solid/gas insulating system and their development into creeping discharges under AC voltage (50 Hz), in a point-plane electrode arrangement, using the (φ q n) (phase, charge, number) matrix. The discharges number and the amplitude of their ap…
In this research, the irradiation influence on optical properties of Cadmium oxide thin films deposited on glass substrate via spray pyrolysis method were studied. The thickness of the prepared thin films were 400 and 500 nm respectively. The flow rate was 10 ml/min and the substrate temperature was held constant at 4…
A systematic density functional theory study is performed to investigate the lattice parameters, the internal positional parameter [Formula: see text] and bond length of RE 2 Sn 2 O 7 (RE = La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu) pyrochlores. To analyze the structural stability in extreme conditions…
A high dielectric, nanodielectric, composite material, MU100, was developed by the University of Missouri for use in dielectric loaded antennas. Based on its dielectric strength and losses, MU100 had possible uses in the development of high energy-density capacitors. This paper presents the dielectric properties of th…
A monolithic 3-bit phase shifter has been fabricated and demonstrates broadband and low loss performance from 220 GHz to 240 GHz.
