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 ...
