This work consists to the development and the characterization of thin films of ZnO and of the bilayer ZnO/TiO2,ZnO/SnO2. The films are deposited by the sol-gel dip-coating and spay methods, onto glass substrate. The heat ...

Adéninium hydrate hemisulfate (C5H6N5 +.1/2 SO42- .H2O) is one of the hybrid materials covering a wide range of compounds wherein the structural cohesion is ensured by the hydrogen bonds. Consisting of a nitrogenous base ...

The Sol-Gel method is a very attractive technique for elaborating materials, since it is known to be able to synthesize ,at low temperature ,both nanometric powders or materials with fine microstructure .moreover, it ...

The results obtained show that the coefficient of thermal expansion of the nanocomposite PE+X%CNT is changed between the radial direction and the longitudinal one, whatever the concentration of carbon nanotubes. According ...

The purpose of this work is the study of some non-relativistic quantum mechanics systems in the context of Feynman path integral approach by using the coordinate time transformations technique and mathematical tools necessary ...

The purpose of the present paper is to analyze numerically the flow and heat transfer by steady laminar natural convection in a elliptical horizontal annulus filled with a Newtonian incompressible fluid saturated porous ...
