The Cr₂AlC carbides oxidized at 700, 850 and 1000℃ in air from 70 hours up to 360 days. They oxidized according to the reaction; Cr₂AlC+O₂ → α-Al₂O₃+CO(g). The scales consisted primarily of the thin, essentially pure Al₂O₃ layer and the underlying Al-dissolved Cr 7 C₃ layer. They grew via the outward diffusion of Al a…
Thermo-chemical removal (TCR), or baking in reactive gases, is a candidate method to control the co-deposit related tritium inventory in fusion devices. TCR can be understood as reaction–diffusion processes in a porous material. O2-TCR was applied to 150–550 nm thick a-C:D layers with similar textures. A linear relati…
In the paper mutual comparison of zinc coatings enriched with small additions of Mg and Al (up to 1 wt.% Mg and 1 wt.% Al) and traditional zinc coatings produced by hot dip galvanizing, concerning some important properties of coatings like coating structure, cracks formation after deformation and corrosion resistance…
M-type barium hexaferrite (BaM) is a promising gyromagnetic material for self-biased microwave\millimeter wave devices because of its large uniaxial magnetocrystalline anisotropy and low microwave loss in high frequency. Due to the limitation of growth conditions, it is difficult to deposit BaM films with enough thick…
Abstract Terrylene diimides with four aromatic heterocycles (AHTDIs) were synthesized under Stille Cross‐coupling conditions and fully characterized by NMR and mass spectrometry. The aggregation of the terrylene diimide (TDI) was suppressed by four heterocycles substituents on the bay region, and these AHTDIs exhibite…
In this paper, Ti–C–N nanocomposite films are deposited under different nitrogen flow rates by pulsed bias arc ion plating using Ti and graphite targets in the Ar/N 2 mixture gas. The surface morphologies, compositions, microstructures, and mechanical properties of the Ti–C–N films are investigated systematically by f…
<div class="section abstract"><div class="htmlview paragraph">Secondary fuel injection is applied to facilitate active soot management of the particulate filter within diesel aftertreatment systems, avoiding concerns with fuel delivery via in-cylinder post-injection. System performance is dependent on the…
The control of the radioactive inventory in the vacuum vessel of ITER is a main safety issue. Erosion of activated plasma-facing components (PFC) and co-deposition of tritiated dust on PFC and in areas below the divertor constitute the main sources of in-vessel radioactive inventory mobilizable in the case of an accid…
Intercalation of highly polar organic compound dimethylsulfoxide (DMSO) with kaolinite and the formation of interlamellar complexes has been studied, and characterized by X-ray diffraction (XRD), Fourier transform-infrared spectroscopy (FTIR). Interaction was found to be dependent on the particle size of kaolin raw ma…
For the present work, the magnetoelectric (ME) composites with composition 0.05 Ni0.8Zn0.2Fe2O4 - 0.95 Ba0.9-3x/2Sr0.1LaxTiO3(NZF-BSLT) with x = 0, 0.01and 0.02 were synthesized by conventional solid state reaction route. The existence of both phases was confirmed by the X-Ray diffraction (XRD) technique. The dielectr…
In this paper, we present the results of the investigation of impact of tensile and compressive stress on the classical Barkhausen effect, magnetoacoustic emission (MAE) signal properties, and B(H) hysteresis loops for grain-oriented (GO) electrical steel. Samples have been glued to a nonmagnetic steel bar and stresse…
This paper presents synthesis of conformal arrays enhanced by metamaterial lenses. The synthesis uses a multi-step Quasi-Conformal Transformation Optics technique to compute lens parameters that allow an arbitrary-shaped conformal array to acquire properties of another desirable conformal array. The approach is demons…
Polyurethanes prepared from anionic initiators, 4,4′-dihydroxy-2,2-diphenylpropane, and aromatic isocyanates were studied by IR spectroscopy. The hydroxy groups in 4,4′-dihydroxy-2,2-diphenylpropane are completely involved in the urethane formation. Variation of the molar ratio of isocyanate and hydroxy groups in the…
The obtained new results of ZnO nanostructures formation in a zinc nitrate/hexamethylenetetramine solution by hydrothermal method on the lithium niobate substrates with synthesized seed-layer by sol-gel technique were presented. The influence of process temperature on morphometric properties of synthesized structures…
Metal-dielectric nanocomposite system with ferromagnetic inclusions was prepared and studied: epoxy resin-xFe (x = 0-30 vol.% is a content of the Fe nanoparticles). Its dielectric and magnetic spectra were measured in a broad frequency range from 106Hz to 1010Hz. Both dielectric and magnetic dispersion was observed. B…
We present the results of ab initio calculations of the anisotropy and hydrostatic pressure effects on the elastic and mechanical properties of (B3) boron nitride, using the density functional perturbation theory (DFPT). The independent elastic and compliance constants, bulk and shear moduli, Zener anis…
A test assembly of carbon coated molybdenum tiles was exposed to a sequence of well-diagnosed ohmic helium discharges in the Experimental Advanced Superconducting Tokamak (EAST) using the material and plasma evaluation system. The test assembly was configured to approximate, on a reduced scale, the profile of a first-…
The paper describes new developments by the All-Russian Scientific Research Institute of Aviation Materials in the field of mechanical rubber adhesives and technologies for their use in aeronautical engineering. The basic properties of cold-setting rubber adhesives and adhesives designed for bonding rubbers with metal…
BET surface area and micropore volume are important factors for improving methane storage in activated carbons (ACs). Specification and optimization of carbon structures are vastly examined by different researchers. However, because of complex relations between independent and dependent variables, the proposed statist…
A comprehensive study of structural, morphological, magnetic and hydrogen absorption properties of LaNi 5 –H system was investigated. The X-ray diffraction patterns show that as-synthesized LaNi 5 alloy is single phase with CaCu 5 -type structure while some weak peaks of elemental nickel also appeared after several hy…
