Abstract: This work consists of modeling and simulating the deposition of graphene films by CVD (chemical vapor deposition) on a catalytic metal (Copper) which represents the result of a surface reaction and implying several gas phase reactions, and for the goal is to predict growth rates in order to obtain a uniform monolayer of graphene, we chose methane as carbonaceous source and the argon as an inert gas. Simulations were performed by using computer code FLUENT <6.3.26>, while trying to see the effects of the parameters such as: choice of precursor gases, the geometry of the reactor, models of calculation of the physicochemical properties, operating temperatures and pressures and essentially the mechanism and reactions retained. The results obtained (in the form of velocity fields, of isotherms, distribution of mass fractions of the components) show that the precise modeling of the hydrodynamics depends mainly on the composition and the flow rate of the mixture on the entry of the reactor, and the difference in the deposition rate is considered due to a change in the thickness of the boundary layer along the substrate. 1 Growth and characterisation of Czts single crystal Safia Kerour Department of Electronics, Faculty of Technology, Ferhat Abbas University of Setif-1 Electrochemical and Materials Laboratory; Algeria Abstract: In this work, we report the synthesis of Cu2ZnSnS4 (CZTS) single crystal by cooling a molten stoichiometric of Cu, Zn, Sn and S elements. Weighed stoichiometric proportions were charged into a 200 mm length and 14mm diameter quartz tube sealed off under 5x10-6 Torr, placed in a horizontal furnace then heated up gradually. Secondary phases between Cu, Zn, Sn with S were formed by keeping the tube in below temperature range (200-700 °C) for 24-48h to reduce the vapor pressure and avoid any explosion in high temperature [1-3]. To ensure homogeneous mixing of the melt, the tube was kept at 1100 °C for 24-48 h. The furnace was then cooled down freely reaching room temperature. Removed from the quartz tube, the CZTS ingot was about 25 mm. The ingot chemical composition analyses determined by Energy Dispersive Spectroscopy (EDS) were found to be nearly stoichiometric. The crystal bulk structure was analyzed by using powder X-Ray Diffraction (XRD), the diffraction peaks indicate a remarkable crystalline nature with preferred orientations of (112) plan. We carried out the Raman measurements which indicate that crystal adopts a kesterite structure without secondary phases. 2 Elaboration and characterization of composites materials based on polypropylene/fumed silica nanoparticles: effect of surface treatment and compatibilizer agent Lasmi Sofiane Research unit of emerging materials, Ferhat Abbas Setif.1 University; Algeria Abstract: In the last years, inorganic nanoparticles filled polymer composites have received increasing research interests of materials scientists, because the filler/matrix interface in these composites might constitute a much greater area and hence influence the composites properties to a much greater extent at rather low filler concentration as compared to conventional micro-particulate composites [1, 2] in this study a composite material based on polypropylene and fumed silica nanoparticles were elaborated by melt compounding in an internal mixer, the effect of surface treatment of silica nanoparticles with the stearic acid (1Wt%, 2Wt%) and PP-greft-MAH as a compatibilizer (1Wt%, 2Wt%) on various properties of fumed SiO2-filled polypropylene composites were studies. The mechanical properties of polypropylene matrix reinforced with silica nanoparticles were determined by tensile and impact test. The reaction of maleic anhydride groups with the hydroxyl groups on the surface of nanosilica was characterized by FTIR spectrum. The final nanocomposites result in a further improvement of mechanical properties because of silica agglomerate reduction and improving interface combination, even loading level being much lower than that of ordinary fillers in conventional composites. 3 Electrochimecal study of self-assembled organic monolayers on a thin silver layer Amira Madi Ferhat Abbas University of Setif 1, Algeria Abstract: Nowadays, the construction of nano-structured materials is a technological approach in full swing. It is based on the design, creation and study of complex structures, consisting of simple elements of nano-metric size. These new materials are generally characterized by particular optical, electronic and chemical properties. The aim of the work is composed of two parts: the first is devoted to the study and the formation of a silver film on a copper support. Industrially these films are obtained from cyanide baths. The substance of the toxicity of these products, research on the formation of thin silver deposits is oriented to other non-toxic baths. The second aim is the study of the electrochemical properties of self-assembled octadecanethiol monolayer on silver deposit. References [1] S. M. Sherif • A. A. Almajid, J Appl.
