Full textDendrimers are hyperbranched macromolecules, synthesized by repeating a sequence of reactions. First (GC1) and second (GC2) generations of phosphorus cationic dendrimers are attached to stevensite and montmorillonite (Rh and AT clays) by cation exchange. This process results in intercalated and exfoliated nanocomposites. The study of the kinetics of adsorption of chromate (CrO42-) on the prepared nanocomposite, and on saturated sodium clays showed that the rate of the adsorption is fast, and that the kinetics is controlled by the diffusion and intraparticule transfer through the liquid boundary layer. Furthermore, the adsorption isotherms are well described by the model of Temkin, fixing the chromate is spontaneous, and the adsorption process is endothermic. The results of analyzes performed by various investigative techniques including solid state NMR show that HCrO4- ions (majority species in the medium considered) would be attached to the silanol and aluminols free edges and surfaces of clay minerals by electrostatic forces type. The kinetics of adsorption of methylene blue (MB) by all the adsorbents is fast, and the activation energy is within the range 6-30 J / mol. The diffusion within the particles and transfer through the liquid boundary layer are the main processes that control kinetics. The adsorption isotherms are better described by the model of Dubinin-Redushkevich. Adsorption occurred spontaneously, and occurs in multilayers, involving among others, sites of pore surfaces. In addition, methylene blue is attached in forms of MB+, (MB+)2 and MBH+2, and following its attachment by the nanocomposites, an ordered structure seems to be formed. The results of the solid NMR analyzes show that the adsorption of MB renders hydrophilic GC1-Rh, that bordering Al IV tetrahedral layers of stevensite reacted with MB species, and that a component of type Q4 is formed

Full textIn the field of toxicological bioassays, the current biosensors are mostly monoparametric and limited in terms of sensitivity and specificity. A more complete toxicity analysis thus calls for combinations to cross-check the results. In this context, the latest progress in Raman spectroscopy opens new research perspectives on a fast method of observing metabolic responses against toxic agents. Indeed, Raman spectra constitute molecular fingerprints of the observed biological samples, offering a global multiparametric view of their physiology. Based on the premise that the molecular variations triggered by a substance on a microorganism affect its spectral fingerprint, this thesis explores the Raman spectroscopy potential of identifying spectral signatures of targeted toxic effects. That said, proper physiological spectral fingerprints analysis requires complex chemometric methods. In the first part of this work, a particular attention has been given to the elaboration of a statistical strategy to highlight the effects of arsenic on the E. coli bacteria. To confirm the specific aspects of the generated spectral signatures, the study has then been extended to the observation of four microorganisms exposed to different kinds of toxic substances (antibiotic, metal, pesticides, phenol compounds). Spectral analyses lead to the identification of the most impacted macromolecules, allowing evidencing of specific toxic effects. Finally, in partnership with the company Tronico Vigicell (CIFRE partner of the thesis) this approach has also been tested on environmental water samples, making this work an integral part of the search for better environmental pollution monitoring solutions

Full textThe conflicting nature of performance, operability and environmental constraints leads engine manufacturers to perform a fine optimization of the burner geometry to find the best design compromise.Large Eddy Simulation (LES) is an attractive tool to achieve this challenging task, and is routinely used in design office to capture macroscopic flow features.However, the prediction of phenomena influenced by complex kinetic effects, such as flame stabilization, extinction and pollutant formation, is still a crucial issue.Indeed, the comprehensive description of combustion chemistry effects requires the use of detailed models imposing prohibitive computational costs, numerical stiffness and difficulties related to model the coupling with unresolved turbulent scales.Reduced-cost chemistry description strategies must then be proposed to account for kinetic effects in LES of real combustion chambers.In this thesis an original modeling approach, called virtual optimized chemistry, is developed.This strategy aims at describing the chemical flame structure and pollutant formation in relevant flame configurations, at a low computational cost.Virtual optimized kinetic schemes, composed by virtual reactions and virtual species, are built through optimization of both kinetic rate parameters and virtual species thermo-chemical properties so as to capture reference target flame quantity

Full textGeosynthetic Clay Liners (GCL) are factory manufactured hydraulic barriers consisting of bentonite supported by geosynthetics (geotextiles or geomembranes). The last few years Geosynthetic Clay Liners are more and more often used as liners or in capping systems of landfills, as a single or part of a multilayer barrier, with traditional materials ( compacted clay or geomembrane). At the present, in most countries, tests on GCLs are performed using standards for geotextiles and low permeable soils, which are not always easy to adapt to GCLs. In this context, the aim of the presented work is to elaborate adapted devices and testing procedures and to study various GCL products (needlepunched, stitched, containing granular or powder bentonite) in real conditions and in similar manner. Original devices were developed in order to study the Geosynthetic Clay Liners hydraulic behaviour in simulated landfill conditions. They allow performing characterisation and performance tests, as well as to study the chemical compatibility with the leachate. The experimental part is focused on the study of the hydraulic performances of 4 products currently available on the market, in various situations: - in contact with smooth surfaces or granular materials; - in contact with a synthetic leachate, the GCL being dry, partially hydrated or saturated with • water. Tests performed on samples with defects allowed to verify the GCL's selfhealing capacity. The chemical compatibility of bentonite to synthetic leachate are analysed as a function of the degree of initial water saturation and of the type of GCL

Full textThe aim of this work is to measure atmospheric pollutants concentrations thanks to low cost devices. For that, we use that is a metallic semiconductor. We tested sensors based on tin dioxide with carbon monoxide (0-20 ppm), a mixture of hydrocarbons (0-10 ppm, ozone (0-500 ppb) nitrogen dioxide (0-500 ppb) and their mixtures. Association of several of these sensors in multisensor array could be a solution to selectivity problem of this type of sensor. We showed the interest in using these sensors for two major pollution components : ozone and hydrocarbons. With an appropriate choice of sensors and measuring parameters. Consecutively with preceding work, several multisensors arrays were carried out. For each studied system, we built behaviour models using method of the Neural Networks. It was shown that a model calibrated directly with urban air appears very effective in the quantitative ozone ad hydrocarbon determination

Full textThe first part of this thesis is a market study of the availability of recycled wood. Each year, in France, 16 million tons of wood waste are collected by specialist companies and waste reception centres. Less than 14% of this is recycled, partially because regulations do not allow highly contaminated wood resources and also because of inadequate sorting techniques, which are often limited to visual assessment. Clearly, recycled wood should be analysed chemically. European standards DD CEN/TS 14778-1:2005 and DD CEN/TS 14780:2005 describe how to obtain samples weighing tens of kg from stockpiles of hundreds of tons. The particles in the sample, often with a top size of several centimetres, must be ground to a fine flour of less than 500 µm. It is impractical to grind the whole sample and so a robust protocol which permits sub-sampling without introducing bias is necessary. A model sample of recycled wood was created using clean particles impregnated with different metals. Different sub-sampling protocols were applied to this model. The samples were analysed chemically in order to see differences via statistical analysis. Standard wet chemistry methods and analyses (ICP-AES and AAS) were used to measure metal contents. In addition, a potentially non-destructive technique based on Fourier Transform Near Infrared Spectroscopy (FT-NIRS) was used to characterize and to predict the presence of metals in wood samples. Multivariate statistical techniques permit the discrimination between particles containing different metals or organic preservatives. It is demonstrated that the level of contamination, particularly with copper slats, can be determined by comparing observations with a database of spectra obtained from known samples (PLS modelling)

Full textGlass is widely used material and especially in constructions. Since 2001, self-cleaning glasses have been launched on the European market. These glasses are based on the photocatalytic property of a submicronic layer of TiO2 deposited on their surface. Under UV-irradiation, TiO2 reacts with the oxygen and water molecules present in the atmosphere to produce free radicals. These radicals are able to degrade organic stains adsorbed on the glass surface. The present work is aimed at a better understanding of the interactions between TiO2 layer and real stains, as well as the photocatalytic physicochemical mechanisms implicated. The influence of different parameters on the self-cleaning glass efficiency has been studied. The photocatalytic degradation of different pollutant families was followed to correlate the nature of the organic compounds to their degradability
