In this work, we have elaborated superconductor compound Y1-xCaxBa2Cu3O7-δ with x= 0.00, 0.01, 0.02, from the oxides (Y2O3, CuO,) and the carbonate BaCO3. The specimens were prepared by the conventional solid state reaction. ...

The work of this thesis concerns the determination of the morphology of the crystallites in a polycrystalline compound. Different shapes for the crystallites can be processed, it is the spherical shapes, cylindrical and ...

In this work, we have prepared the Nano powder and thin films of ZnO pure and doped Al with ( 5%,7%) by sol-gel technique and have annealed at (450°C ,750°C). then we analyzed the specimens by X rays diffraction and ...

This work is a part of study of the crystal structure by experimental (X-rays diffraction method) and calculated molecular conformation (DFT density functional theory) of an organic and aromatic compound diiodochloromesithylene ...

This work focused on the development and characterization of single crystals of KCl and KBr pure and doped by the particles of SrCl2 (H2O). The prepared nanocompositesKBr /KSr2Br5 andKCl / KSr2Cl5 were the subject of a ...

In this work, the semi-conductor nanoparticles of PbS trapped in Y zeolite were investigated. As a first step, we synthesized NaY faujasite by the sol-gel route. As a second step, the Pb2+ were fixed on the zeolite by ionc ...

In this work, composite silver / silica were studied. In a first step, the Ag+ ions of various compositions (2.5, 5, 7.5 and 10%) were fixed on the silica by ion exchange. In a second step, the samples were annealed in air ...

In this work, we have undertaken the study of two sheets AlMgSi alloys (6XXX series). Which have a great interest for their privileged uses in automotive and aeronautical industries. The aim of the present work is the ...
