Results of works on estimating the environmental hazard classes of ashes and slags from power-generating facilities are presented. It is determined that the overwhelming majority of ashes and slags from power stations can be related to nonhazardous materials, which can be used as secondary raw mineral stock in produci…
Abstract An automatic calibration function for a dynamic drive scheme has been developed to stabilize the contrast ratio and the number of colors for color electronic paper. We use the pixels' capacitance to detect their optical characteristics. We can accurately distinguish 4,096 colors; only a few colors were practi…
A hysteresis of electron spin resonance spectra, which indicates a first-order phase transition, has been revealed in α′-(BEDT-TTF) 2 IBr 2 single crystals in the temperature range 15–30 K. Two lines corresponding to the high-temperature and low-temperature phases have been observed in the ESR spectra.
The structure, polarizability and magnetic properties of Zn n O n and Cu-doped Zn n-1 O n (n=2-12, 16) clusters are theoretically investigated using density-functional theory (DFT) at B3LYP/LanL2DZ level. For pure Zn n O n clusters, Zn 3 O 3 , Zn 8 O 8 and Zn 12 O 12 are relatively more stable unit, and the Zn n O n c…
A wedge-shaped 304 austenitic stainless steel with varied thickness longitudinally was cold rolled into a flat one and then annealed at 1323K for 10 min. The grain boundary character distributions (GBCDs) in the specimen as processed were examined by the means of Electron backscatter diffraction (EBSD). The results sh…
The dielectric study of Sr 0.73 Ba 0.27 Nb 2 O 6 :Ce (SBN) crystals along [010] crystallographic axis was performed in the temperature region of 310-360 K and frequency range from 25 Hz up to 1 MHz. The thermal dipole relaxation of quasi-Debye-type for this orientation of sample was observed in both investigated struc…
In this study, we investigated the control of the orientation and ordering of self-assembled nanodots from a block copolymer (BCP) with the help of a guide pattern created by electron beam (EB) drawing. The guide pattern consisted of a post lattice and guide lines. The former is used to enable self-assembled nanodots…
Woven natural silk fabric has been commonly used in textile industries for centuries. Irrespective of their mechanical and environmental merits, their utilizations as reinforcement material for composites structures are very rare. Therefore, this work is focused on the use of woven natural silk as a reinforcement mate…
The integration of micro electromechanical systems (MEMS) with ICs is one of the key technologies for MEMS ubiquitous applications and commercialization. This paper therefore presents a high sensitive micro disk resonator with on-disk piezoelectric PZT thin film as the transducer for better impedance matching to CMOS,…
The formation of gold nanoparticles and clusters in solutions of reverse micelles formed by Tritons X-45, X-114, and X-100 (polyoxyethylene isooctylphenyl ethers with degrees of polymerization n = 5, 7–8 and 9–10, respectively) in the presence of sodium sulfite is studied. The stability of these particles is shown to…
Chemical products detection and analysis has been demonstrated as a powerful diagnosis method for SF6gas-insulated switchgear (GIS). In this paper, Materials Studio software was used to simulate single-walled carbon nanotube (SWNT) detecting gas decomposition products of SF6in partial discharge (PD). The simulation re…
The purpose of this study is to investigate the performance of 5kW-Class Solid Oxide Fuel Cell/Gas Turbine (SOFC/GT) hybrid systems with two typical turbine configurations widely used in the gas turbine industry, namely single and dual-spool gas turbines. Even though their operations are based on the same physical pri…
This paper presents a novel and easily controllable method for measurement of the interaction of single-wall carbon nanotubes (SWNTs) with surfaces using simple cantilever beams, a nanomanipulator, and a scanning electron microscope (SEM). A small SWNT bundle is assembled across two cantilevers by dielectrophoresis, w…
We have investigated the low-frequency noise of ZnO film deposited by dc sputtering technique on glass substrate. We characterized the noise below 100kHz and obtained classical 1/f spectra. We attempted to verify the validity of Hooge's empirical relation and to test its usefulness as a diagnostic tool. The 1/f noise…
Based on the finite element analysis with centered finite difference, this paper focuses on 3-D analysis of three kinds of shaped charge penetrating to concrete. The process of forming penetrators is depicted in the test together with the process of penetration, which shows that under the same condition of diameter, t…
Graphene has emerged recently as an attractive channel material for high frequency analog device applications. High carrier mobility and large gate capacitance are both desirable attributes for such devices. A main obstacle however in depositing thin dielectrics on graphene, with high dielectric constant is its chemic…
Aluminized coatings were prepared on AZ91D magnesium alloy using pulsed bias magnetron sputtering. Effects of deposition temperature on the microstructure and corrosion resistance were studied. The microstructure, element distribution and hardness of the coatings were characterized using optical microscopy (OM), X-ray…
119Sn atoms produced by radioactive decay of 119Sb impurity atoms in the structure of As x S1 − x and As x Se1 − x glasses are stabilized in the form of Sn2+ and Sn4+ ions at arsenic sites and correspond to ionized states of the amphoteric two-electron center with negative correlation energy (Sn2+ is an ionized accept…
Morphological characteristics and electronic structures of platinum-containing nanosystems obtained during a redox reaction in water medium at different concentrations of a stabilizing polymer and platinum were studied by atomic-force microscopy (AFM), X-ray photoelectron spectroscopy, and dynamic light scattering. It…
