Our ethnobotanical survey of medicinal flora character in the west and south-west region of Algeria, has allowed us to establish a floristic inventory of medicinal plants. Identification of 183 species, distributed in 56 ...
This work is devoted to the synthesis and characterization of new series of low-cost adsorbent materials thoroughly regenerable derived from a low value cellulose and lignocellulosic wastes (olive stone and timber sawdust) ...
In this work, a co-doped Bi-Zn-TiO2 photocatalist is synthesized by an original synthesis route of layered double hydroxide followed by heat treatment at 670°C. After characterization the photocatalyst efficiency is estimated ...
In this work, we are interested water resources polluted by chemicals which
can cause various health problems .A For example, phenols are an important source of
pollution, and are essentially the result of industrial ...
During this work, the study was focused on the optoelectronic properties of ordered and disordered superlattices (SR's) based Arsenic types (III-V). We discuss the impact of the aluminium concentration on the laser wave ...
By mean of different numerical methods, many theoretical studies predict several
intermetallic Heusler compounds to be half metals at room temperature. This class of
materials is usually in base of spintronic applications ...
Waste management has long been a natural action of the population and is now becoming a major concern for developing countries.

Nowadays, adsorption is recognized as one of the major significant separation processes
amid the physical, biological, and chemical processes.
Activated carbon adsorption has been widely used for the purification of water ...
In this study we presented the importance of water in human life and its pollution by toxic elements. The possibility of Treaty and to preserve the environment has led to the application of treatment processes by inorganic ...
This thesis falls within the general framework of the treatment of wastewater by
conventional and emerging processes. Three nano-materials were utilized to develop the aim
of this work. The three materials were characterized ...
The anthraquinone dye Acid Green 25 (AG25) was treated by a non-thermal plasma generated by a
new GlidArc, designed for the treatment of liquid films falling. The gaseous species formed in the
landfill, especially the ...
We explored in this study the crystal structure determination of single crystal of organic compounds with charges transfer
that belongs to the family of thiazole derivates. These heterocyclic systems are of great importance ...
