In this paper, the synthesis of four-layered functionally graded materials (FGMs) samples of (TiB2)pNi/(TiB2)p(Ni+Ni3Al)/ Ni3Al with different metallic substrate (Ni, Cu and Cr-Ni steel) by field-activated and pressure-assisted synthesis process (FAPAS) was investigated. It was shown that the imposition of the electri…
Titanium alloys, whose chemical composition is given in Table 1, are used in engineering structures for special applications. Content (%)AlloyAlVZrCFeSiO2 N2 H2 VT1-0–––0.070.300.100.20.040.01PT-3V...
Article Crystal structure of dichloro-bis(2-morpholinoethylamino)copper(II), Cu(C6H14N2O)2Cl2 was published on April 1, 2009 in the journal Zeitschrift für Kristallographie - New Crystal Structures (volume 224, issue 1-4).
Thermo-shock resistance of the thermal protection materials is affected by its heat, mechanical properties, and various environmental factors. Therefore, it is very essential to understand which factors take great roles in affecting thermo-shock resistance and how much they affect, when designing the thermal protectio…
A quantum-mechanical formula for describing the dependence of the longitudinal permittivity of a nanotube on its characteristic parameters and the magnetic field strength was derived. The imaginary part of the permittivity was isolated, and the cases of a Boltzmann and degenerate electron gas were examined. For a dege…
Magnetic and structural characteristics of magnetically diluted complex oxides La2−x A x MO4 (M is Fe; A is Sr, Ba) were studied. An essential dependence of magnetic susceptibility on the composition of dia- and paramagnetic components of the structure and also the tendency of heterovalent iron atoms to form clusters…
Silicon nitride coatings were prepared by chemical vapor deposition (CVD) method. The effect of raw precursor materials (SiH4 and NH3) ratio, gas flow amount, reaction temperature, and reaction pressure and deposition time to the microstructure, chemical compositions and crystal structures of the silicon nitride coati…
Phase equilibria with the participation of a liquid phase in the Mg-MgO-B ternary system at 2 GPa have been calculated in the framework of model approximations of the phenomenological thermodynamics. The melting diagram of the system is characterized by five nonvariant four-phase equilibria, three of which are peritec…
This paper is concerned with formability of AZ31B magnesium alloy sheets at various temperatures. In order to acquire the forming limit curve for quantifying the formability of the magnesium alloy sheet, hemispherical punch forming tests are performed under various temperatures. The initial shape of the blank is recta…
Previous in vitro studies conducted in our group have shown the feasibility of monitoring drug release from liposomes by an inertial acoustic cavitation index. We currently report in vivo experiments utilizing the cavitation index in combined treatment of AT2 Dunning tumor grafted rats with focused ultrasound and lipo…
Article Crystal structure of diaqua-bis(fra/is-4,4'-azobispyridine)cadmium(II) perchlorate – methanol (1:2), [Cd(C10H8N4)2(H2O)2](CIO4)2*2CH3OH was published on April 1, 2009 in the journal Zeitschrift für Kristallographie - New Crystal Structures (volume 224, issue 1-4).
An investigation has been made on the infiltration behaviour in rapid prototyping of Al alloy parts under different infiltration atmospheres. An Al 6061 alloy preform was first prepared by selective laser sintering. Then the aluminium precursor powders in the preform were converted into AlN to form a skeletal AlN stru…
Acicular nano-hydroxyapatite (n-HA) was used to make a new biomaterial composite with polycarbonate by a novel technique. The physical and chemical characteristics of the composites were tested. It was found that the synthesized n-HA crystals were similar to bone apatite in size, phase composition and crystal structur…
We have performed micromagnetic simulations for the design of toggle magnetoresistive random access memory (MRAM) cells to make the operating field as low as possible while keeping a reasonable margin and thermal stability. The memory cells are composed of weakly coupled synthetic antiferromagnets. The cells are diamo…
The electropolymerisation of a range of indole derivatives results in the formation of redox active films. These redox films have been observed to be highly luminescent. Earlier studies have investigated electrochemical and photophysical properties, for potential applications such as fast response potentiometric senso…
La doped ZnO nanorods were synthesized via solvothermal technique using Zn(AC)2 and La(NO3)3 as starting materials. The products were characterized by X-ray diffraction (XRD), field scanning electron microscopy (FESEM) equipped with an energy dispersion X–ray (EDX) spectrometer, photoluminescence spectroscopy and UV-v…
Verschiedene handelsübliche Bleifrei-Schutzschürzen werden mit Blei-Composite- sowie Bleischürzen unter praxisnahen Bedingungen hinsichtlich der Schutzwirkung verglichen.

ZrB2are widely applied because of some excellent performances; however, ZrB2is easily oxidized in the high-temperature air. To reach better Al ( OH )3– Y ( OH )3composite shell and higher coating ratio on the ZrB2particles surfaces, ZrB2particles must be adequately dispersed in the ZrB2suspension during the coating pr…
