Lattice dynamical investigations have been made to study the zone centre phonons of USiO4 in scheelite phase having space group I41/a by employing Wilson GF matrix method. The present calculations to find Raman and infrared wavenumbers involve four stretching and six bending force constants. The calculated results are…

Gadolinium zirconate(Gd2Zr2O7) nanocrystals were prepared via two different combustion methods: citric acid combustion(CAC) and stearic acid combustion(SAC). The effects of the different preparation methods on the phase composition, microtopography, and sintering densification of the resulting Gd2Zr2O7 nanopowders wer…
A new 3D complex,[Co(L)(bpe)0.5(H2O)2]n(1,H2 L = 5-iodo-benzene-1,3-dioxyacetic acid,bpe = 1,2-bis(4-pyridyl)ethylene),has been hydrothermally synthesized and structurally characterized by elemental analysis,IR and X-ray diffraction.It is formulated as C16H16 Co INO8,crystallizes in monoclinic,space group P21/c,with a…
This paper presents the results of investigations of a dissimilar welded joint made between X10CrMoVNb9-1 (P91) martensitic steel and TP347HFG austenitic steel. The welded joint material was taken from a primary steam superheater coil operated at maximum working temperature of approx. 540°C for more than 105 000 hours…
The dynamic oscillatory test and multiple stress creep recovery (MSCR) test are designed to evaluate the high temperature properties of asphalt binders and the two test methods may present consistency as well as difference when characterizing asphalt binders. Therefore, these two tests were performed on linear and rad…

We have synthesized Fe/Fe3C magnetic nanoparticles embedded in an amorphous carbon globule by pyrolysing of benzene, ferrocene and hydroboric acid. The diameter of the globules is similar to 1 mu m and that of Fe/Fe3C magnetic nanoparticles is similar to 40 nm. The globules exhibit ferromagnetic like behavior and the…
Here, we report results of electrical and magnetic characterization studies on polycrystalline (1-x) BiFeO3-xPbTiO3 (BF-xPT) thin films of compositions x = 0.25.0.30 and 0.35 near the morphotropic phase boundary. All films show saturated ferroelectric hysteresis loops at room temperature. DC leakage current studies re…
Nano-crystalline Mn0.5Zn0.5Fe2O4 was synthesized by chemical co-precipitation method and characterized with X-ray diffraction. Ac electrical impedance data are taken for the frequency range of 1Hz to 1MHz for various temperatures from 303K to 483K. The ac electrical conduction deviates from the Debye type relaxation w…

Ultra-thin InP passivated GaAs metal-oxide-semiconductor based non-volatile flash memory devices were fabricated using InAs quantum dots (QDs) as charge storing elements by metal organic chemical vapor deposition technique to study the efficacy of the QDs as charge storage elements. The grown QDs were embedded between…
In this study, graphene filled epoxy nanocomposites were prepared using solution casting method. The graphene at different composition (0.25 0.5, 0.75, 1.0, 1.25 and 1.5 wt. %) were mixed with epoxy before the addition of hardener using mechanical stirring and ultra sonication. The produced nanopolymer composites were…
パワーMOSFETパッケージの熱流束分布はダイの発熱エリアに大きく影響される。異なる動作条件での温度特性が違うため，発熱分布も異なる。その結果，飽和領域(Vth < Vgs < Vth+Vds)とBody-Diodeモードで測定した熱抵抗値に差が見られる。本論文は，市販のパワーMOSFETを用いて過渡熱測定を行い，CFDシミュレーションの熱モデル合わせこみ技術を使用してこの現象を解析する。

Polymer composites of poly(vinyl alcohol) (PVA), doped with different concentrations of ammonium dihydrogen phosphate (ADP) has been prepared by solution casting. The formation of complexation between ADP and PVA was confirmed with the help of Fourier transforms infrared (FTIR) spectroscopy. Thermogravimetric analysis…
Nanostructured multiferroic Bi(1-x)BaxFeO3 x=0.0,0.1,0.2 were prepared by hydrothermal technique. The morphology of the particles changed with the doping of barium. Effect of barium doping on the dielectric constant was studied over a wide frequency range. The magnetization at the highest available field (∼1.6T) incre…
Calculation of pile quay gantry type as a frame with rigid crossbar and a rigid beam is a special case of the decision method, presented by N. Gersevanov. This method was widely used in the technical literature and regulatory documents. Translation of manual calculation on the computer almost retained the existing des…
