We report on the magnetic properties and magnetocaloric effects of Mn5Ge3-xGax compounds with x=0.1,0.2,0.3,0.4,0.6 and 0.9. All samples crystallize in the hexagonal Mn5Si3-type structure with space group P63/mcm and order ferromagnetically.The Curie temperature of these compounds decreases with increasing x, from 306…

In this article, preparation of nano-graphite powders in a steel chamber by using pure TNT (trinitrotoluene) explosives has been reported. X-ray diffraction results indicated that the black solid powders which were collected from the wall and the bottom of the chamber after detonation have the graphite structure and t…
Pulse irradiation simulating reactivity-initiated-accident (RIA) condition was conducted for test rod prepared from fuel irradiated in a commercial reactor and fission gas release behavior from fuel pellet during pulse irradiation was investigated. Optical microscopy (OM) and scanning electron microscopy (SEM) observa…
The thermal conductivities of granular UO2 compacts with and without uranium particles were measured to evaluate the thermal performance of vibro-packed granular MOX fuels containing metallic fine particle oxygen getters. The thermal conductivity of the compact with 10 wt% of uranium particles was higher than that of…

We demonstrate the potential of interference lithography in the DUV by examples of two-dimensional patterns that have been obtained by multiple exposure techniques. Using immersion prisms we realized gratings with more than 10 000 lines/mm.
This paper presents research achievements and development trends of automobile light-weight in developed world, and mainly on the production characteristics of AHSS, besides that, discusses the customer-oriented application technology in automobile steel sheet. Also, this paper discusses the future of automobile light…
The effect of crosslink density of unsaturated polyester resin on the corrosion resistance was investigated. Cured unsaturated polyesters with different crosslink density were immersed in pure water and potassium hydroxide solution. Since the weight of resin increased in proportion to the square root of immersion time…
An attempt has been made as a fundamental study on monitoring of high temperature oxidation of carbon steel with an AC impedance method. A typical environment of hot air at 873K was preferred for acceleration tests of oxide film growth. Two specimens of carbon steel were faced with each other with a narrow gap, which…
In order to improve the corrosion resistance and biocompatibility of NiTi surgical alloy, TiO2 and TiO2-SiO2 thin films were prepared by sol-gel method. The surface characteristics of the film, which include surface composition, microstructure and surface morphology, were studied by X-ray diffraction (XRD), atomic for…
PbZrO3 (PZO)/PbTiO3 (PTO) artificial superlattices have been grown on La0.5Sr0.5CoO3 (LSCO) (100)/MgO (100) substrate by pulsed laser deposition (PLD) with various stacking periods from 1 to 100 unit-cells. The ferroelectric properties of the superlattices were investigated by scanning probe microscopy (SPM). We have…
Continuous solid solutions were isolated within the system AICd1-xMIxPO4(AI=Li, Na; MII=Mn, Co) for 0≤x≤1. The steady decrease of the lattice parameters and unit cell volume within the solid solution domains was ascribed to the substitution of Cd2+ cations by smaller size M2+ ions (M=Mn, Co) as the composition progres…
The carbonate ion with a triangle shape is always isolated from other carbonate ions in the crystal structure of a carbonate. The rare earth atoms in carbonate minerals tend to have higher coordination numbers in comparison with those in the silicates and phosphates, owing to the lower negative charge per an apical ox…
We investigated the sol-gel synthesis process of barium titanate ultrafine particles with using barium hydroxide aqueous solution and titanium alkoxide solution. Emphasis was placed on the relationship between the mixing condition of both solutions and the properties of the particles. A static mixer was used as reacto…
The polyaniline(PAni)coating was electrochemically deposited on nickel skeleton electrode and nickel foil by potential sweep between − 0.2 V and 1.2 V/SCE, with a scan rate of 20 mV s−1; acid aqueous solutions containing 0.027 mol L−1aniline in 1 mol L−1sulphuric acid were used. The PAni film was studied by IR Spectro…
Thermal conductivity modeling using the Debye approximation can significantly reduce the complexity involved in the evaluation of thermal conductivity integral. Nevertheless, there are several compelling reasons (e.g., inconsistency between the estimations of the density of states used for heat capacity and thermal co…
The aim of this paper is to present a new control mode of AC switch (thyristors, triacs ...). The applied signal on the device gate is a "high frequency" alternating sine, instead of a pulse-shaped signal. This solution has been retained in order to integrate galvanic isolation with power-controlled switches. Control…
Exotic leather is an important part of the leather industry, which is worth approximately three billion dollars (Sterlacci, 1997). Due to an increased fashion emphasis on exotic leather apparel, it is now considered a fashion staple rather than a trend. This study was part of a larger project, conducted by a multi-fac…
Results of ferroelastic domain structure evolution and XRD studies near the superprotonic phase transition in mixed [(NH4)1−xRbx]3H(SO4)2 are reported. A theoretical description of the high temperature phase transition on the basis of phenomenological theory is proposed.
