Titanium tetrachloride with inorganic salts as raw materials in the experiment, TiO2is prepared by the hydrolyzation method in (NH4)2SO4-modified TiCl4solution, the maximal photocatalytic activity is observed at the mole ratio of TiCl4: (NH4)2SO4=1:2, the water-bath temperature of 90°C. Bromophenol blue solution is de…
La réversibilité des doublages est une question complexe et intimement liée à la pénétration des adhésifs au sein de la toile originale. Cette investigation a consisté en la recherche des facteurs d’influence et la mise au point d’une méthode d’évaluation de la pénétration. Les adhésifs testés sont les plus fréquemmen…
The presence of radioactive material in scrap metal (SM) or the semi-finished products of the metal recycling industries may cause health, economic, legal, and public acceptance problems. This paper deals with the risk assessment in the recycling of the contaminated SM, and its legal aspects, regulation, and control.…

Thermo-mechanically treated (TMT) bars have rapidly replaced the conventional High Yield Stress Deformed (HYSD) bars in RCC constructions. Due to the heat treatment on TMT bars, the surface toughness of such bars gets altered. Crack initiation and propagation characteristics of such bars vary significantly from that o…
Distribution of SiC particles in powder metallurgy (P/M) Al/SiCp composite during hot extrusion were investigated in this paper. It has been shown that a homogenous distribution of SiC particles in as-extruded rods has been achieved. There was an order and directional distribution of SiC in the longitudinal direction,…
We describe the synthetic route towards a novel class of salts, trifluoromethylsulfonylsulfates, as exemplified by the silver(I) derivative (AgS2O6CF3). Formation proceeds via direct reaction between a triflate precursor, AgSO3CF3, and SO3. The title compound crystallizes in the P2(1)/c unit cell with a = 5.15746(14)…
In this study, a method for modeling incompressible, immiscible three phase fluid flows in the context of incompressible smoothed particle hydrodynamics (ISPH) in two dimensions has been proposed. Continuum surface force model is employed while physical surface tension coefficients are expressed as the sum of phase sp…
Co/Pd multilayer films are prepared on fcc-Pd underlayers of (001), (011), and (111) orientations hetero-epitaxially grown on MgO single-crystal substrates at room temperature. The effects of underlayer orientation, Co and Pd layer thicknesses, and repetition number of Co/Pd bi-layer on the structure and the magnetic…
Local heating system composed with micro heater and microfluidic channel is designed and fabricated. Micro heater made of platinum film is formed on a slide glass by radio-frequency magnetron sputtering and lift-off processes. Microfluidic channel is designed to surround the micro heater. A SU-8 epoxy-based negative p…
The Paclitaxel-eluting stents (PTX) with three-layered polymer coating were studied in this work. The PLGA (polylactic acid-co-glycolic acid) with 15 percent PEG (poly ethylene glycol) concentration in blend have been applied for preparing multiple layer drug carrier and fabricated on the surface of 316L stainless ste…
One-step rapid synthesis of colloidal nano-MnO2 suspension from KMnO4 solution has been readily carried out in the presence of nanocellulose whiskers (NCW) upon a sonochemistry procedure at room temperature. NCW that plays a triple role of a reducing agent and a support, as well as of a stabilizer, has been introduced…
The objective of this study was to provide background date on rice straw pyrolysis in molten KCl(40mol%)-LiCl(60mol%). The effects of pyrolysis temperatures and sweep gas flow rates on the pyrolysis products yields and their chemical compositions were studied. The temperatures of pyrolysis and sweep gas flow rates wer…
To increase the hardness of ion-nitrided stainless steels, a plastic deformation is performed previously to the nitriding treatment in order to generate dislocations used afterwards as diffusion paths for atoms. In this work, influence of different plastic strain rates on the surface hardness improvement is studied. T…
P-i-n single-junction hydrogenated amorphous silicon (a-Si:H) thin film solar cells were successfully fabricated in this study on a glass substrate by high density plasma chemical vapor deposition (HDP-CVD) at low power of 50 W, low temperature of 200°C and various hydrogen dilution ratios (R). The open circuit voltag…
Equipment has been designed and created for experimental simulation of space environment conditions of Geostationary orbit of the Earth. The following conditions are supported in the vacuum chamber having volume of 1.2 cubic meters: Vacuum 10-5 Torr. (1.3 × 10-3 Pa), electron beam with energy up to 8 MeV, temperatures…
The research aims to identify the mechanical characteristics of an amorphous metallic alloy as cast and after heating, and suggests the effects of applications of such a material as a filler in composites. The amorphous state of Zirconium-based alloy is obtained through melt-spinning and is identified by X-ray diffrac…
We have observed three kinds of Raman scattering spectra for the following materials: (1) the bamboo-based carbon filaments inside historical incandescent lamps fabricated by Ichisuke Fujioka and Thomas A. Edison, whose results were compared with those of a bamboo-based carbon filament annealed in our laboratory and a…

Over the past few years, car manufacturers have been considering ever higher service temperatures for the engine in order to comply with the constraints of depollution standards. The requirements in terms of exhaust gas temperature could easily reach and overtake the limits of common stainless steel grades used for su…
