Biomolecules and nanostructured systems : characterization by Surface Enhanced Raman Scattering (SERS)
2014
This work addressed the study of several kinds of nanostructured systems, biomolecules and inorganic thin films, mainly by Surface Enhanced Raman Spectroscopy (SERS). The aim was to investigate the structure and the chemical bonds. Transmission electron microscopy (TEM) was also used to complete the structural characterization of the different samples.Firstly, the study was conducted on molecules of biological interest. The aim was to study the interaction between silver nanoparticles and proteins. With this aim, silver nanoparticles bioconjugated with different proteins (hemoglobin, cytochrome C, BSA and lysozim) were synthesized. SERS results allowed concluding that proteins are chemisorb…

Within the quick nano-fabrication techniques evolution and the increasing needs in low space and energy opto-electronic functions on-chip integration, studies and control of electromagnetic resonances of sub-micrometric objects are crucial issues. One aim of this work was then to improve our knowledge of the light-matter interaction. To this end, optical near-field experiments and complementary numerical development of models have been performed to study electromagnetic resonances due to light-matter interaction in sub-micrometric resonators. As an introduction, the first part of the manuscript presents the main phenomena involved in near-field optical microscopy and the used SNOM operation…
Solution stoichiometry determines crystal stoichiometry in halogen-bonded supramolecular complexes
2007
The behavior of the methylisonicotinate (MINC) building block as halogen bonding-acceptor module has been investigated in the solid state. Both the N and the O atoms of MINC interact with the iodine atoms of 1,4-diiodotetrafluorobenzene (DITFB) giving rise to N⋯I and O⋯I interactions. Hierarchy between these interactions allows the control of the composition and thus the structure of the supramolecular complex, according to the composition of the reaction mixture. A structure based on an infinite chain and a trimeric supermolecule have been obtained starting from a 1 ∶ 1 MINC/DITFB stoichiometry or by using a large excess of MINC, respectively. While the former structure shows simultaneous …

La valorisation des compétences de base sur le marché du travail français
2013
D’après la théorie du capital humain, les individus sont rémunérés selon leur productivité, productivité qui dépend elle-même du niveau de diplôme ou du nombre d’années d’études. Mais à l’heure où l’éducation certifiée est discutée comme filtre, qu’en est-il de la valorisation des compétences, notamment de base, sur le marché du travail français ? Alors que de nombreuses recherches ont déjà été réalisées à ce sujet (dans les pays anglo-saxons principalement), aucune n’a encore été conduite sur cette thématique en France. Cette présente étude cherche alors à déterminer, via un modèle d’Heckman en deux étapes, dans quelle mesure l’accès à l’emploi et les salaires sont expliqués par le niveau …
Un biais d'estimation de la rentabilité de l'éducation dans le modèle de gains de Mincer appliqué à des données transversales

Estimation de la relation de salaires de Mincer : choix de specification et enjeux économétriques
2012
In the present doctoral thesis, we estimated Mincer’s (1974) semi logarithmic wage function for the French and Pakistani labour force data. This model is considered as a standard tool in order to estimate the relationship between earnings/wages and different contributory factors. Despite of its vide and extensive use, simple estimation of the Mincerian model is biased because of different econometric problems. The main sources of bias noted in the literature are endogeneity of schooling, measurement error, and sample selectivity. We have tackled the endogeneity and measurement error biases via instrumental variables two stage least squares approach for which we have proposed two new instrum…
