The storage and delivery system bed provides rapid and safe functions for storage and delivery of tritium gas in a fusion power plant. In order to investigate the hydrogen isotope effect, we prepared a small-sized (1/10) ZrCo bed. Based on hydrogen-deuterium gas mixtures with various composition 0, 25, 50, 75 and 100…
It has been reported that a temperature gradient can have a major influence upon the space charge distribution in polyethylene (PE) and oil-impregnated paper however details of the mechanism by which these modifications are produced have not yet been clarified. The experimental results for PE under a temperature gradi…
Unusual backward and forward wave propagation in below cut-off waveguides loaded with dielectric metamaterials comprised of linear arrays of dielectric resonators (DRs) has been investigated by using theoretical, numerical, and experimental methods. Transmission bands were shown to correspond to three lowest resonance…
Various lipid particulate drug delivery systems with liposomes as forefront have attracted increasing attention in cancer treatment, especially breast cancer therapy. Multidrug resistance and off-target cytotoxicity are among major obstacles faced by researchers in this area. To address these problems, various strateg…
A novel method was used to make palygorskite supported nano-silver powder at room temperature. XRD result showed the presence of silver in the final product. TEM investigation revealed that nano-sliver particles of 6-10 nm in diameter were successfully attached on surface of palygorskite fiber. FTIR was also used to c…
This document proposes a statistical classification model using principal component analysis (PCA) for a data reduction approach combined with self-organizing map (SOM) for a classification purpose, so called, PCA-SOM model compared with SOM model to classify partial discharge pattern (PD) into four categories listed…
The present work deals with two different CdS nanostructures produced via hydrothermal and solvothermal decompositions of aminocaproic acid (ACA)-mixed Cd-thiourea complex precursor at 175 °C. Both nanostructures were extensively characterized for their structural, morphological and optical properties. The powder X-ra…
Analysis of radiation damage in natural mineral analogs such as zircon is important for the evaluation of the long-term behavior of nuclear waste forms and for geochronology. Here we present results of experiments to determine the partitioning of radiation damage due to the heavy nuclear recoil of uranium and thorium…
In this paper, the experimental phenomenon of transformation of electrical tree to water tree in XLPE cables is reported, the conditions and mechanism of the transformation are discussed. Electrical treeing aging experiment was used to obtain electrical trees in short XLPE cable samples, and water treeing accelerating…
Influence of low amounts (1.0-2.0wt-%) of nanostructured silica and calcium carbonate fillers on the large-area dielectric breakdown performance of bi-axially oriented polypropylene (BOPP) is analyzed. A multi-breakdown measurement method based on the self-healing breakdown capability of metallized film is utilized fo…
In this paper, five types of catalysts, (i.e. SnO2/PdO/γ-Al2O3, CuO/PdO/γ-Al2O3, PdO/γ-Al2O3, CuO/SnO2/γ-Al2O3 and CuO/SnO2/PdO/γ-Al2O3) were prepared by multiple step impregnation for the catalytic combustion of benzene. The catalysts were characterized by XRD, BET, H2-TPR and IR to investigate the internal structura…
This paper presents a soft starting control scheme of a three-phase induction motor using a PWM AC chopper technique to reduce the magnitude of currents during a start up process. To control bidirectional power switches in the PWM AC chopper, a PWM signal is generated by a single voltage signal, and compared with a si…
In this work, the dielectric properties of epoxy/POSS composites with different contents of Glycidyl-POSS varying from 1 wt% to 5 wt% were investigated using Broadband Dielectric Spectroscopy (BDS) at 20 °C. Besides the known β-peak in the vicinity of 100 kHz, no additional loss peaks were found for the epoxy/POSS com…
Palladium(II) complexes of aromatic hemiporphyrazines were prepared by the reaction of bis(dibenzylideneacetone)palladium(0) with the corresponding metal-free macrocycles. Single crystal X-ray analysis revealed that a palladium(II) ion was coordinated inside the macrocyclic cavity to form two Pd – C bonds. Electronic…
Thermal characteristics of the phonon and magnon subsystems of icosahedral borides RB66 (R = Gd, Tb, Dy, Ho, Eu, or Lu) have been studied based on the obtained experimental data on the thermal expansion of the borides and the earlier results on their heat capacity in the range of 2–300 K. The contribution to the expan…
In case that the vibrating capacitive probe of an electrostatic voltmeter is facing a metallic plate of known electric potential V, which can be easily imposed by connecting it to a DC high-voltage supply, the value displayed by the instrument is equal to V. The same surface potential measurement technique is employed…
Dispersion relations of Love mode acoustic guided waves propagation in Pb(Mg 1/3 Nb 2/3 )O 3 −33%PbTiO 3 (PMN-0.33 PT) single crystal with a gold electrode film are calculated. There is no cross coupling among Love wave modes, which is conducive to eliminating the cross interference between modes. The general formula…
The composites of piroxicam and meloxicam with gamma-alumina, aluminium hydroxides (gibbsite and boehmite), alpha and gamma polymorphs of iron(III) oxide having dierent surface area and morphology were prepared by planetary ball-milling. It has been shown that the initial state of the excipient (specic surface area, p…
Needs for the performance improvement of memory subsystem in big data and clouding computing era begin to open new markets for emerging memories such as phase change memory, spin-torque-transfer magnetic memory, and metal oxide memory. To fulfill these needs, a cost-effective and high-speed phase change memory cell sc…
When a liquid phase is cooled below its freezing temperature, it usually transforms to a crystalline solid where the disorder-order transition is driven by the thermodynamic requirement of reducing the entropy in the corresponding thermodynamic potential of the system. However, some liquids do not crystallize because…
