The objective of this thesis is to study the influence of anisotropy on the quality of AlN thin films, developed by two physical vapor deposition (PVD) techniques, DCMS and HiPIMS. AlN exists in two phases: a stable hexagonal ...

The present work deals with the elaboration and characterization of nanometric thin layers of binary and ternary transition metals and rare earth silicides. The binary system samples were obtained by implantation of ...

The aim of this work was to synthesize, by soft and hydrothermal means, MOFs structures, based on lanthanides and squarate on the one hand, and inorganics structures of lanthanide sulfates, on the second hand. The compounds ...

The principal objective of this thesis is based on the synthesis of two amide-based quinoléine dérivatives, and seven original organic compounds of imine derivatives Shiff’s base] of bidentate NO type, tridentate NOO and ...

This doctoral thesis is devoted to the study of azo dyes and their organometallic complexes, which are a particular class of chemistry whose importance and interest to remain our considerable days. The dye industry is ...

This thesis focuses on the synthesis and the structural characterization by x-ray diffraction on powder and monocrystal and by different spectroscopic methods, as well as by thermal analyzes and the study of the magnetic ...
