The thermal management is crucial to the safety and lifespan of Solid Oxide Fuel Cell (SOFC) generation system. For the model-predictive control design, a model of SOFC thermal management system is proposed on the least squares support vector machine (LS-SVM). The model is composed of some thermal modules including SO…
Infrared spectroscopy and X-ray diffraction are used to evaluate the OH and H 2 O environments in 10 Å phase (“TAP”), nominally Mg 3 Si 4 O 10 (OH) 2 ·H 2 O. Two partially deuterated samples of TAP synthesized under different conditions have very similar IR spectra, indicating that the phase has a reproducible structu…
Although outer wall thermal insulation technology is an effective measure for building energy-saving, the production of thermal insulation materials causes serious impacts on environment. In the present investigation the resource, energy consumption and environmental emission of the two kinds of thermal insulation mat…
Graphene nanoribbon (GNR) relinquishes the zero band gap technology provides the promising candidates in electronic conduction. Lessening the width in nano scale as a ribbon creates considerable bandgap. The effect of changing the width of GNR, classical capacitance follows the linear curve need higher analysis of qua…
In order to investigate the effect of nickel saturation on the corrosion of Type 316L stainless steel (SS 316L) by Pb-17Li, a SS 316L test capsule was fabricated and filled with Pb-17Li along with some Ni chunks. The system was maintained at a temperature gradient of 923 to 623 K for 3200 h. Characterization of SS 316…
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 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…
