To study the effects of substrate materials on the photocatalytic activity, TiO2films were immobilized on the inner wall surface of ceramic, glass and stainless steel tubes by sol-gel method. X-ray diffraction (XRD) results indicated that the crystal form of TiO2were all anatase type with theoretical particle size of…
Epitaxial and textured EuBa2Cu3O7-x(EuBCO) superconductive films were prepared via a F-free polymer-assisted chemical solution deposition (PACSD) method on LaAlO3 (LAO) single crystal substrate in nitrogen atmosphere. Because of the fluorine-free metal organic system, no harmful gas was produced during processing by t…
Hydrogenated amorphous silicon thin films were deposited using a high pressure sputtering (HPS) system. In this work, we have studied the composition and optical properties of the films (band-gap, absorption coefficient), and their dependence with the deposition parameters. For films deposited at high pressure (1 mbar…
Paper transferring gripper is a key part of printer. In this work, plasma spray technology was adopted for the coating of 5 different metal oxide ceramic layers on metallic substrate. The friction and wear performance of different plasma-sprayed metal oxide ceramic coating on the gripper surface were comparatively stu…
In the paper the stress-strain of pristine and defective single walled carbon nanotubes are investigated. The defects are in the form of point vacancies. The axial deformations of structures are studied only. A special attention is focused on the effects of material and geometrical properties of nanostructures on the…
Data from measurements of the disintegration kinetics of hydrogen phases in palladium and titanium during annealing and irradiation with a synchrotron radiation bunch in the X-ray spectral region on the VEPP-3 LIGA Technology station are presented. The hydride phases in palladium and titanium remain stable at sample t…
Previously unknown [ML2(H2O) n ] bischelates, where M is Mn(II), Co(II), Ni(II), or Cu(II) and L is deprotonated triformylmethane, are studied by X-ray diffraction analysis. It is revealed that in the crystals of all compounds there are multiple hydrogen bonds linking bischelate molecules into polymer layers or a sing…
Crystal structure and microstructure of La0.7-xHoxSr0.3MnO3 (x=0.2,0.6) prepared by usual ceramic techniques and grinding procedure were investigated using X-ray diffraction (XRD) and transmission electron microscopy (TEM). When doping amount x equals to 0.2, incorporation of Ho atoms contributed to phase separation a…
In this paper graphene is used to improve absorption rate of nano-titanium dioxide under visible light, meanwhile titanium dioxide is doped with superparamagnetism nano-powder of γ-Fe2O3 to modify the recovery of the photocatalyst. Gradually the increasing content of grapheme promotes the removal efficiency and corres…

Nanocrystalline Copper doped Tin Selenide have been prepared by aqueous solution method in double distilled water at room temperature. All the chemicals used for this were of Analytical Reagent grade and of 99.999 % purity. Structural confirmation of prepared compound and particle size estimation was done from X-ray d…
The luminescent material, composed of rare-earth-doped alkaline earth aluminate, has been paid wide attention because of its chemical stability, usability and non-radioactive. In this study, the luminous material SrAl2O4:Eu2+,Dy3+ was prepared by a microwave method. The effect of microwave parameters on the performanc…
Abstract Summary: Quantitative 13C NMR spectroscopy is used to determine reactivity ratios and end group and branching frequency of ethylene‐styrene and ethylene‐isobutylene co‐polymers synthesized at a temperature T = 205 °C and pressure p = 1650 bar at different levels of co‐monomer fraction. In the forefront of the…
In this work, it is demonstrated that dipalmitoyl phosphatidyl glycerol (DPPG) liposomes can be adsorbed without rupture on a rough polyelectrolyte layer-by-layer (LbL) film. The adsorption kinetic curves revealed that this process is governed by a diffusion phenomenon with a characteristic time of approximately 20 mi…
Fuel Cells are promising energy conversion devices with a high efficiency and low emissions, especially if hydrogen is used as combustible.However, the-state-of-the art electrolyte and electrode materials do not yet fulfill the stringent requirements of some funding agencies and much remains to be done to reach these…
Different post-metallization annealing gas ambient has been performed in the gadolinium oxide resistive switching memories to enhance the fabrication yield. The superior memory properties such as the low set and reset voltages (-1.4 V and 2.1 V) and high resistance ratio (~104) are successfully achieved. With no degra…
