Our study is interested in the investigation of the chemical composition and the biological activities of Algerian propolis. In the first part of our study we examined several propolis harvested from Algerian East in order ...
The main purpose of this thesis is based on the synthesis and characterization of new coordination compounds based on alkaline-earth metals. Two synthesis methods were used to prepare these materials: synthesis by way of ...
The catalytic activation of hydrogen peroxide (H2O2), persulfate (PS) and peroxymonosulfate (PMS) by organometallic FeIII and CuII complexes has been applied in the removal of several types of pharmaceutical pollutants in ...
This thesis work presents the synthesis, the characterization by infrared and UV-visible spectroscopic methods, and the structural study by X-ray diffraction of seven new complexes based on copper and the following nitrogenous ...
The objective of our work is to carry out phytochemical and biological studies on the Algerian plants Inula conyza DC, Centaurea incana Desf belonging to the Asteraceae family, and Lathyrus latifolius L of the Fabaceae ...
In the present work, the aerial parts (1200 g) of the Saharan plant Hammada articulata underwent maceration in 80% ethanol. After filtration, the solution obtained was concentrted (37°C) then added with distilled water ...
This work describes a thesis that is divided into two chapters. In the first chapter, a synthesis of novel benzimidazolium salts is presented as N-heterocyclic carbene precursors (NHCs), along with the synthesis of their ...
This thesis focuses on the synthesis of new porous coordination polymers based on pyromellitic acid. The crystal structures of the hybrid materials have been solved from single-crystal X-ray diffraction data and the ...
Aromatic compounds containing azo or azoxy functions are widely used in the chemical industry as color pigments, food additives, indicators, initiators of free-radical reactions and therapeutic agents. The treatment of ...
In this work, two parts have been developed. The first is devoted to the synthesis, characterization and theoretical study of new meso-substituted dipyrromethanes. These compounds have been synthesized by a double ...
The present study focused on the phytochemical investigation and the evaluation of the
antioxidant activity of two plants: Anagallis monelli ssp. linifolia (L.) (Primulaceae) and Arenaria
cerastioides (poir.) (Caryophyllaceae). ...
This work is devoted to the phytochemical study of two endemic Saharan plants, Asteriscus graveolens (Forsk.) DC. and Crotalaria vialattei Batt. belonging respectively, to the Asteraceae and Fabaceae families. These two ...
The pollution caused by heavy metals has been increasing in recent years, posing a threat to ecosystems and human health. This study focuses on the adsorption and cation exchange of chromium (III) and manganese (II) on ...
Three new Schiff bases derived from DHA and substituted aniline have been synthesized. Their structures were principally determined by crystallography and IR spectroscopy. The electrochemical study of these compounds was ...
This thesis examines a promising new method for the effective depollution of water contaminated by organic pollutants such as pharmaceutical products. This advanced oxidation method is based on heterogeneous photocatalysis. ...
1,10-phenanthroline and its derivatives are widely used in chemistry and biology, these molecules are useful in a range of biological (anti-Alzheimer, antifungal, anticancer,...) and chemical processes. Tin (IV) complexes ...
This study focused on the synthesis of new hybrid materials composed of tin hexachloride
and ligand matrices. The structural analysis and physico-chemical characterisation of these
compounds were carried out using ...
The main objective of this study is to detect of secondary metabolisms of four species of plants belonging to the Lamiaceae family, Rosmarinus officinalis. L, Thymus algeriensis (Boiss et Reut), Thymus numidicus (Poiret) ...
The Fenton process is widely recognized for its efficiency in advanced oxidation of wastewater; however, its large-scale application is hindered by the need for an acidic
pH to prevent metal precipitation. In this study, ...
In the first part of our research, our aim was to identify the phenolic content of the hydroalcoholic extract of the plant Ammoides atlantica, which belongs to the family Apiaceae, by using the RP-UHPLC-ESI-QTOF-MS ...
