L’observatoire de la transition socio-écologique en Franche-Comté. Une référence pour l’Observatoire « Drââ » de la Province de Ouarzazate

2018

This paper presents the principles, method and main results of the Observatory of the Socio-Ecological Transition in Franche-Comté (OTSE-fc). The latter is currently used as a reference for the development of the Drâa observatory of the Province of Ouarzazate as part of the CNRS-CNRST scientific cooperation project 2015-2016. At the request of the participants of the workshop, we also summarized the progress of the territorial diagnosis of the Province of Ouarzazate, which constitutes the basis of the Drââ Observatory. The advances concern a diagnosis carried out among 1650 inhabitants of the province, its main quantitative results and a first exploitation of a qualitative analysis exposing…

ZnO(core)/TiO2(shell) composites : influence of TiO2 microstructure, N-doping and decoration with Au nanoparticles on photocatalytic and photoelectro…

2017

The aim of the thesis is to study the influence of microstructure of ZnO/TiO2 composites on their properties in photocatalytic degradation of organic pollutants, and in photoassisted water oxidation. To realize such study we chose the design based on ZnO nanorods supported on ITO (Indium Tin Oxide)-coated glass electrode. The ZnO nanorods were then covered with a layer of TiO2 under different conditions. The composition and microstructure of the obtained ZnO(core)/TiO2(shell) composites were modified in the aim to elucidate how these parameters influence their photocatalytic activity. The results of studies lead to elaboration of two most distinctive variants of sol-gel procedure that allow…

Phosphine-diène and Salicylamidines ligands : coordination chemistry, catalysis and therapy

2017

The subject of this thesis concerns the development of new ligands, their coordination chemistry, and the synthesis of the corresponding metal complexes for catalysis and therapy.The first part of this work relates to the synthesis of diene-phosphine ligands, their saturated analogs, and the corresponding arene-ruthenium complexes. Arene decoordination allows the formation of a cationic bimetallic complex where the ligand is diène-η4/κ-P coordinated to the ruthenium. These complexes have been applied to atom transfer radical addition (ATRA) of CCl4 to styrene. When harsh reaction conditions are used, the superiority of the “diene” complexes is highlighted comparing to saturated analogs.The …

P-chirogenic secondary phosphine oxides : new synthesis and applications

2015

A new stereoselective synthesis of phosphinous acid boranes is described by hydrolysis of aminophosphines boranes prepared by reaction of the oxazaphospholidine complex derived from ephedrine with organolithium reagents.By reaction with a strong acid, the phosphinous acid boranes lead to the corresponding P-chirogenic secondary phosphine oxides in very good yields (90%) and with complete retention of the configuration at the phosphorus atom. The secondary phosphine oxides have been used in asymmetric hydrogenation and intramolecular Heck cyclisation using rhodium and palladium complexes, respectively. In a second part, a new synthesis of P-chirogenic ortho-halogenophenyl phosphine oxides is…

Polyamines and applications. A look at the first workshop in linear and cyclic polyamines chemistry

2008

Given their versatile coordination properties, cyclic and linear polyamines are the subject of numerous worksin many research groups. This great interest is mainly related to their use in diverse fields such as removalof metals from liquids, purification of gases, application in catalysis, in sensors, as well as in various probesfor medical applications. This paper summarizes recent results obtained by the French research groupswhich attended the first ìworkshop in linear and cyclic polyamines chemistryî.
