We present an ab-initio and analytical study of the Jahn-Teller effect in two diluted magnetic
Semiconductors (DMS) with d4 impurities, namely Mn-doped GaN (III-V) and Cr-doped ZnS( II-VI). We show that only the combined ...
The objective assigned to this project is the development of a method for determination of the influence of raw sand
physico-chemical characteristics on the production yield of the liquid sodium silicate.
Three kinds of ...
Using the first-principles method we investigate the electronic and magnetic properties of the diluted magnetic
semiconductors Zn1-xMnxO and Cd1-xMnxO with x = 25%. The calculations are performed by a developed ...
Pollution of water and soil from various industries are major sources of pollution Activated carbons are
porous adsorbents produced from various carbon precursors, which are widely used in bleaching
processes water

Le présent travail est une contribution à l’étude de la gestion des déchets en Algérie qui fournit les données de référence sur le compostage des ordures ménagères et de déchets verts, qui constituent la grande partie des ...
In our laboratory SEA2M , we develop activated carbon obtained from biomasse in water
traitement. The behavior of activated carbon is studied using FT-IR transmission
spectroscopy. The aim of this work is to,introduce ...
On a exposé trois espèces de menthe (poivrée, verte et basilic) à trois genres de stress (la chaleur, le froid et l’obscurité). Ceci s’est traduit par une surproduction de flavonoïdes. On a étudié la réponse génétique et ...
The work presented in this paper is based on three main axes:
The first theme focuses on determining the structure of a new family of insecticidal pyrethroids - C21H16N2O4FClBr2 - from a spectrum of X-ray diffraction. ...
The paramount objective of our work, within the framework of the environmental protection was devoted to the study of the process of electrosorption, for the elimination of cations.
An experimental study concerning the ...
Synthesis, characterization and structural study by diffraction of the X-ray
of tri(8-hydroxyquinoléine) aluminium .
The principal topic of this memory bases on the synthesis and the
characterization of tri(8-hydroxyquinoléine) ...
Zeolites are alumino-silicates materials whose pores have a characteristic size
comparable to the size of various organic or inorganic molecules. They have some
interesting adsorption and catalytic properties, porous ...
