This study focused on the application of photochemical processes (direct photolysis and advanced oxidation processes) in the degradation of an ionic liquid; 1-hexylpyridinium bromide (HPyBr) in aqueous solution. These ...

The work undertaken through this thesis responds to the problematic of proposing new access routes in the context of multi-component reactions, to a wide variety of heterocyclic molecules, highly functionalized and ...

Seven Schiff bases were synthesized and characterized by hysicochemical methods. The imines were prepared by the condensation of the amines: 2-aminiphenol, 2-amino-4- chlorophenol, 2-amino-4-tert-butylphenol and ...

The main purpose of this thesis is based on the s-vnthesis and structural characterization of new complexes u,ith two type of ligands; symmetric Schiff bases acetylacetonate bis (salicylhydrazone). asymmetric acetylacetonate ...

The crystal structure of novel organic-inorganic hybrid material 2-carboxyanilinium hypophosphite has been determined using X ray diffraction data. We also determined the structure using theoretical calculations to establish ...

The syntheses, done and repported in the present thesis, consists of two steps, the first one is a heating reaction, in an homogenus batch reactor, the second is the formation of a coordination compound, by environmental ...

The photodegradation under artificial and solar irradiation of Naproxen (NPX, induced by 3 iron (III) oxy (hydroxide) based semiconductors (Goethite) was studied in aqueous solution in heterogeneous phase. The phototransformation ...

Quantum gravity is a physical theory designed to unify general relativity and quantum mechanics, which are inconsistent and incompatible and each one has a different scale from the other, the first is macroscopic while the ...

The use inhibition is one of the most practical method for the protection of metals against corrosion, especially in acidic media. Most of the well known inhibitors are organic compounds containing heteroatoms such as ...

In the current situation of global warming and depletion of oil reserves, the use of proton exchange membrane fuel cells (PEMFC) needs further improvements. In this work, two numerical 3D models have been developed; ...
