Full textPolyoxometalates (POM) are anionic compounds formed by the assembly of metal oxide polyhedra {MOy}, (with M, MoVI or WVI) linked together by oxygen atoms. POM thus form a remarkable class of nanometric inorganic metal oxide clusters, with a wide variety of charges and structures. It is possible to form hybrid systems including the inorganic part of the POM and a grafted organic part, allowing new functionalities to be added to the POM, such as selfassembly. We have dedicated this thesis work to the characterization of standards, hybrid and self-assembled POM systems by mass spectrometry coupled to ion mobility spectrometry (IMS-MS). A first experimental approach using drift tube ion mobility spectrometry (DTIMS) allowed us to determine the collision cross sections (CCS) of standard POM in helium and nitrogen. The CCS of the POM standards then allowed us to calibrate an IMS cell of a Travelling Wave ion mobility instrument (TWIMS). The analysis by IMS-MS of organic-inorganic hybrid POMs alone or in the presence of transition metal cations revealed the presence of self-assembled triangular [POM3·cation3], square [POM4·cation4] or pentagonal [POM5·cation5] systems with different charge states. CCS values of these self-assemblies was estimated from the calibration of the TWIMS cell. Using a theoretical approach, we modelled several standard POM structures with and without tetrabutylammonium counterion (TBA+) using density functional theory (DFT). The optimized structures were used to determine theoretical CCS using the trajectory method of the MOBCAL software, in which we incorporated molybdenum and tungsten atoms for which we optimized new Lennard Jones potential parameters. The correspondence of experimental and theoretical CCS of standard POM structures offers new possibilities for structural attribution of self-assembled hybrid POM by coordination in the presence of metal cations

Full textThe increasing use of pesticides in agriculture may be responsible for significant soil contamination. Study on the behaviour of pesticides in soil is then necessary to assess environmental risks and particularly pesticide transfer to surface water and groundwater. The aim of the study was to investigate the behaviour of two triazole fungicides, bromuconazole and furconazole, in soil under laboratory and field conditions. The mobility, adsorption-desorption and degradation phenomena were mainly studied in two different soils. Evaluation and comparison of the mobility of these fungicides and a third fungicide, triadimenol, in both soils was achieved using soil thin-Iayer chromatography. Improvement of this technique was proposed, specially for the slightly mobile compounds, with successive elutions on the same soil thin layer plate. The mobility studies were completed by sorption experiments. The main interest of these studies was to assess and compare adsorption and desorption characteristics of the fungicides on both soils to investigate the possible influence of certain parameters (nature of compound, types of soil, soil/water ratio of the suspension). Adsorption kinetics was carried out and described by modelling to analyse the speed of attainment of sorption equilibria and to determine the appropriate time to reach equilibrium. The determination of adsorption coefficients (according to FREUNDLICH and TEMKIN isotherms) allowed to quantify adsorption; the desorption studies by successive desorptions have proved hysteresis effect. A laboratory experiment was conducted to investigate the degradation of bromuconazole in soil to determine the degradation rate, the formation of bound residues and the amounts of main metabolites. Degradation was also studied under field conditions; outdoor microlysimeters experiments were conducted to investigate simultaneously mobility and degradation of the fungicide in both soils. These studies allowed to emphasize the usefulness and limitation of methods used as devices to assess the environmental fate of applied chemicals

Full textIn different fields of research, modeling has become an effective tool for studying and predicting the possible evolution of a system, particularly in epidemiology. Due to the globalization and the genetic mutation of certain diseases or transmission vectors, several epidemics have appeared in regions not yet concerned in the last years. In this thesis, a model describing the transmission of the chikungunya epidemic to the human population is studied. As a novelty, this model incorporates the spatial mobility of humans. Indeed, it is an interesting factor that has influenced the re-emergence of several epidemic diseases. The displacement of mosquitoes is omitted since it is limited to a few meters. The complete model (ODEs-PDEs model) is then composed of a reaction-diffusion system (taken the form of semi-linear parabolic partial differential equations (PDEs)) coupled with ordinary differential equations (ODEs). We prove the existence, uniqueness, positivity and boundedness of a global solution of this model at first and then give some numerical simulations. In such a model, some parameters are not directly accessible from experiments and have to be estimated numerically. However, before searching for their values, it is essential to verify the identifiability of parameters in order to assess whether the set of unknown parameters can be uniquely determined from the data. This study will insure that numerical procedures can be successful. If the identifiability is not ensured, some supplementary data have to be added. In fact, a first identifiability study had been done for the ODEs model by considering that the number of eggs can be easily counted. However, after discussing with epidemiologist searchers, it appears that it is the number of larvae which can be estimated weeks by weeks. Thus, we will do an identifiability study for the novel ODEs-PDEs model with this assumption. Thanks to an integration of one of the model equations, some easier equations linking the inputs, outputs and parameters are obtained which really simplify the study of identifiability. From the identifiability study, a method and numerical procedure are proposed for estimating the parameters without any knowledge of them

Full textFor almost a century, the researchers have been making important efforts in order to bring new properties to materials and nowadays surface modification of materials is more than ever a very attractive research subject related to a variety of promising industrial applications. The development of simple methodology to characterize biomolecular interactions has been, over the years, an indispensable technology to support researches in the areas of biology and microbiology due its high degree of sensitivity. Surface functionalization by chemical coating is a promising solution to obtain numerous well-defined properties. This study presents the feasibility of gold surface functionalization using a chemistry based on aryldiazonium salts to the biosensors development applied to Surface Plasmon Resonance (SPR) technology. A high-quality technique used to measure biomolecular interactions in real time in a label free environment. Since many years, industrial activities are responsible to the pollution of the atmosphere. Although different greenhouse gases being involved in atmospheric pollution, CO2 is still one of the most important due its high concentrations in the atmosphere and due to its ability to induce serious health disease. Several studies in the literature have demonstrated that some adsorbents such as activated carbons, basic functionalized silica sieves, zeolites, etc.. although commercially available are still sophisticated and expensive limiting their application. However, there is still a need to capture CO2 for activities with limited operating cost. The objective of this study is to promote the cocoa shell, an agro-waste resource ready to use and easy to modify, as low-cost materials for CO2 adsorption and toxins removal from industrial waste in solution applying a chemical treatment from diazonium salts and silane compounds to modify its physic-chemical properties

Full text"tradition used to be at the turn of the century, that no longer exists and more and more people don’t understand why you would even want not to live in the United States. And I think that’s probably going to increase. PN: You often use tourism and movement as figures of desire in your work. In Motion Sickness, for example, the narrator says of her relationship with Zoran that ‘We’re best when we’re in motion. Which is probably why we fuck most of the time’ (M, 104). But the title of the novel is Motion Sickness, and mobility seems to be shadowed by forms of fixity—‘National identity is like armor’, the narrator concludes at one point (M, 127). Are there positive and negative forms of tourism? The novel does at one point refer to ‘a true tourism in which you would find yourself outside your homeland, and outside your body, and see yourself with emotional vividness, as you can’t, and in the roles you play to others…’ (M, 120–1). LT: Obviously I’m being ironic about calling it a ‘true tourism’. It’s not that you find yourself, but that you can look at yourself. When you go somewhere else and see new things you’re also trying to be a different person in a new place. Of course you can’t ever do that really. But what you keep hoping for is getting outside yourself, your country…so that in a way you wouldn’t exist. That may be a ‘positive’ form of tourism. (laughs) PN: What exactly is the ‘sickness’, then? LT: I think that any desire indicates lack. If you say ‘I want’, even if it shows some sort of agency—that the ‘I’ wants something—it also indicates that you don’t have what you want at the time. So there’s this curious movement between these two poles of desire and lack, which obviously come out of each other. I think in the same way we move because we want some kind of satisfaction; on the other hand, the desire for movement may be the product of an unbearable and never-ending kind of sickness, which is that you can never fulfil all the need for motion that you’ve got. PN: Motion Sickness seems to express something like the situationist sense of drift—there’s a reference to the idea of the dérive at one point (M, 149)—but at the same time that sense of abandonment is very ambivalent. ‘When longing’s absent, when I feel no specific desire for anything, anything I can name, I vacillate, feel determined, content or empty’ (M, 193)—isn’t that kind of ambivalence actually rather different from what the situationists had in mind? It seems to inform much of the speculation about desire and identity which runs through your work." In Textual Practice, 52. Routledge, 2005. http://dx.doi.org/10.4324/9780203986219-18.
