The objective of this work is a study of the structural properties (lattice parameters, total energy, bulk modulus) and electronic properties (band structure, density of states) of rare earth monochalcogenides LaX (X=Se, ...

Nanotubes are of great interest due to their high surface-to-volume ratios and size-dependent properties. Titanium dioxide nanotube array is a well-known nanostructured semiconductor oxide with improved functional ...

La structure électronique des VC est fondamentalement intéressante et technologiquement import ante. Avec le code de simulation WIEN2k, nousavons effectué des calculs de propriétés électroniques en utilisant la théorie de ...

The knowledge of the mechanical behaviour of Al-Mg-Si alloys during a heating cycle is very important. Metallographic investigation of samples of these alloys allows us to know the change in the grain size. X ray diffraction ...

The present study deals with ZnS semiconductor nanoparticules incorporated in zeolite. The zeolitheY is synthesized using sol–gel method. In second, the Zn2+ ions are fixed on the zeolite by ionic exchange. Finally, γ rays ...

For the preparation of purification elements in our daily life at low cost, thin layers of zinc oxide and ZnO doped with copper (0%, 4%, 6%) were deposited on pellets of ceramics constituted Cristobalite, mullite and zircon. ...

In this work, we have made a parallel study using both powders and thin layers of TiO2 doped by copper (Cu). Annealing temperatures effects and the Cu dopant concentration on the phase composition, chemical banding and ...

Recent developments in radiotherapy techniques, particularly VMAT technique is a tool of choice in the treatment of tumors with complex shapes such as head and neck cancers. Patients with head and neck cancer are prone ...

Cuprous oxide (Cu2O) is a well-known oxide semiconductor with a band gap of 2.1 eV and a natural p-type conductivity, which is an attractive material for device applications because of its abundant availability, non toxicity, ...

Algeria, which has an exceptional solar potential with over 3000 hours of sunshine and an area of 2.381.745 Km2 decided to implement a strategy to develop various applications of solar energy and in particular the solar ...
