The phase transformation due to mechanical loading in cold-rolled stainless steel 301LN sheets is investigated experimentally. A series of uniaxial tension experiments is performed to quantitatively investigate the effect of initial anisotropy on the martensitic transformation kinetics. Three methods are employed to m…
We report on anodic homopolymerization and copolymerization of aniline (Ani) and pyrrole (Py) on composite 2B pencil graphite in aqueous medium. The electrochemical syntheses of these polymers in para -toluene sulfonic acid with and without potassium chloride (KCl) are investigated. The presence of KCl in the medium h…
The interaction between the additive components chloride, accelerator, and suppressor is the focus of the present paper. Based on Frumkin and Damaskin's adsorption theory, an advanced concept for the superfilling mechanism is introduced. Cyclovoltammetry measurements show the additive impact on the current–potential b…
Automatic recognition of skin symptom plays an importance role in the skin diagnosis and treatment. Feature selection is to increase the classification performance of skin symptom. In this paper, the effects of feature selection on the classification of 4-class skin symptoms (chloasma, blackhead, freckled and comedone…
In view of the problems of using traditional monitoring method for SF6 gas leakage in electrical equipments, according to the photoacoustic spectrometry technology, the photoacoustic spectrometry experiment system is designed for detecting SF6 gas concentration. The generation of photoacoustic spectrum is presented, t…
Destructive oxidation of ethanol in the corona discharge reactor The results of investigation of ethanol destructive oxidation (model aliphatic alcohol) in a corona discharge reactor are presented. The process was performed at the temperature of 303 K in the corona discharge generator - the reactor system manufactured…
Some TiO2 powders, prepared from titanium(IV)tetraisopropoxide by the sol‐gel method and thermally treated between 100 and 1000∘C, have been characterized by X‐ray powder diffraction and by nitrogen adsorption and desorption at 77 K to calculate the BET‐specific surface area, from which the micropore volume and the ex…
Ca-P-O films were prepared by laser CVD using Ca(dpm)2 and (C6H5O)3PO metal organic precursors. The crystal phase of Ca-P-O films changed depending on deposition temperature (Tdep), total pressure (Ptot), laser power (PL) and molar ratio of Ca to P (RCa/P). β-TCP films in a single phase were obtained in a P-rich and h…
Abstract The electronic structure of a new type of polyoxometalate [Ti12Nb6O44]10− has been investigated using density functional theory (DFT). The calculations represent that the LUMO in fully oxidized [Ti12Nb6O44]10− delocalizes among the titanium (Ti) and niobium (Nb). Therefore, both Ti and Nb have the probability…
The aim of this study was to increase compatibility of immiscible PLA/PCL blend by using elec- tron beam irradiation in the presence of glycidyl methacrylate(GMA). The blends of PLA/PCL containing GMA were irradiated at doses of 10, 50 and 100 kGy and then the irradiated samples were characterized by observing morphol…
The rotationally resolved spectrum of the o-toluidine S(1)<-- S(0) origin was measured using laser induced fluorescence spectroscopy. From the resulting spectrum torsional barriers to internal rotation of the methyl group were derived, which resulted in S(0) state values of V(3) = 699 +/- 11 cm(-1) and V(6) = 64 +/- 1…
A multiscale simulator for alumina film growth inside a nanoporous material during an atomic layer deposition process is developed. The model combines a continuum description at the macroscopic level of precursor gas transport inside a nanopore during exposure to each of the two precursor species (trimethyaluminum and…
Electrochemical oxidation of a bent donor molecule ethylenedioxy-ethylenediseleno-tetrathiafulvaleno-thioquinone-1,3-dithiolemethide (EDO-EDSe-TTFVS, 1) and the corresponding quinone derivative EDO-EDSe-TTFVO (2) in the presence of (Bu4N)MCl4 (M = Ga, Fe) affords single crystals of three radical cation salts, 12FeCl4,…
In present contribution we discuss the structural properties of the austenite and martensite phases that form in as-spun ribbons of some selected compositions of the ternary system Ni50Mn50-x(In,Sn)x, their characteristic crystallographic texture and the effect of vacuum annealing. X-Ray diffraction analysis showed th…
Hollow-core waveguides based on high contrast gratings are analyzed using exact analytical formulation. We obtain dispersion diagrams and propose a planar geometry similar to a heterostructure to confine the light two dimensionally in these waveguides.
The performance of integrated circuits has been growing exponentially, which has resulted in the development of a variety of VLSI products for communications, computers, and medical applications. The increase in the performance is mainly due to the decrease in the dimensions of the integrated circuit chip. To sustain…
Accumulations and spatial and dynamic variations of biofilms in the media of a biotrickling filter were simulated using mathematical models for Volatile Organic Compound (VOC) removal. Toluene was selected as the model VOC. Effects of toluene concentration and gas Empty Bed Contact Time (EBCT) on VOC removal were also…
Electroluminescence (EL) consisting of three bands at 500, 600, and , respectively, is observed from the implanted with Ge ions at low energies. The EL intensity under either constant-voltage or constant-current injection is significantly enhanced by higher implant energy. It is shown that the EL enhancement is partia…
Zinc oxide with a hexagonal wurzite type structure is an unique material that exhibits semiconducting, piezoelectric and pyroelectric properties. These properties play a key role for applications in optoelectronic devices. In the present work Al-doped and undoped ZnO films were obtained by soft chemistry starting with…
Detecting and removing minor faults in power transformer winding is essential because minor faults may develop and lead to major faults and finally irretrievable damages occur. In this paper in order to detect the position of short-circuit in the winding, frequency response of the input impedance of a power transforme…
