Vectorized internal radiotherapy is based on the administration of radiopharmaceuticals to patients by the oral or intravenous route. Unlike external radiotherapy, this modality has no standard dosimetric methods that are ...

In this work, we are interested in the study of thin films based on metal oxides elaborated by two chemical methods namely the pyrolysis spray and the sol-gel dip - coating. Our study is first focused on the effect of ...

Steel remains the only material capable of simultaneously supporting considerable forces and loads, but sometimes its use is limited by some of their surface-related properties, the main one being a very bad corrosion ...

The thin films and xerogels of titanium oxide (TiO2), undoped and doped with erbium (Er3+) have been synthesized by the sol-gel process. The xerogels have been characterized by DSC and Raman. The results show that: the ...

In this work, it is the possibility of the preparation of cement phosphomagnisium, which quickly hardened at room temperature, starting from a local raw material available and no expensive which is dolomite. Dolomite was ...

The purpose of the work of this thesis is to develop and characterize the structure and magnetic superconducting ceramic samples Bi2Sr2CaCu2O8+δ were prepared by the Sol-Gel method. These are superconducting ceramics based ...

Amorphous selenium (a-Se) is an important photoconductive material used as a lightsensitive layer in X-ray digital imaging detectors. The performance of these detectors is determined by the electronic transport properties ...

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 ...

In this work, we studied the intergranular segregation of zircaloy 2 and zircaloy 4 alloy elements in zirconium on the basis of the first principles ab initio of quantum mechanics. Using the ...

The work undertaken in this thesis is reserved for the study of aluminium alloys of different shapes. We are interested in the role of thickness on the different mechanical, spectroscopic, thermodynamic and structural ...
