Les couches minces de carbone amorphe hydrogéné ou DLC présentent un grand intérêt technologique grâce à leurs propriétés performantes souvent proches de celle du diamant. Ces propriétés sont obtenues lors de la formation ...

Pure and Al doped zinc oxide nanopowders have been synthesized by sol-gel method. This method permit to obtain a very small grain size (23-36 nm), with grain size in undoped ZnO powder are larger than those Al doped ZnO ...

In this work Al doped ZnO thin films were deposited on the silicium substrates by a dip coating sol–gel technique. The influences of annealing temperature on the structural and optical properties of aluminum doped ZnO ...

Durant la dernière décennie, les nanocomposites à base d’époxy chargée de particules inorganiques ont rapidement pris de l’importance, car ils peuvent offrir de remarquables améliorations en termes de propriétés mécaniques ...

Notre étude a mis en évidence de deux mécanismes d’action différents des dopants par la méthode des mélanges. Un mélange binaire de 63% ZrO2, 37%La2O3 et un mélange ternaire avec différents pourcentages de l’oxyde d’Indium ...

The aim of this paper is to study the electromagnetic properties of a periodic structure in the context of meta-materials. The design tool is the HFSS software which uses the finite element method. The extraction of ...

Structural, electronic and mechanical properties of main YCu2 and YZn2 binary Laves phases with C14, C15, C36 and CeCu2 in Cu-Y-Zn alloy are investigated by firstprinciples calculations. The related total energies versus ...

In this work ZnO and ZnO doped vanadium (1 - 6 %) thin films were deposited on glass substrate by the pulsed laser deposition technique. The films were deposited at 500°C under oxygen ambient pressure of 10-2 mbar with ...

Ferritic stainless steels, in general, and the first generation of the group 430, in particular, are associated with many problems during the welding process. These problems are the grain growth, both in the fusion zone ...

The optical scattering and absorption of gold nanorods (GNRs) depends on its size, shape, andsurroundings. This dependence is due to both intrinsic and extrinsic effects. A good understandingof this dependence is needed ...
