"Can you ever really trust a machine? It is the near future. A couple are struggling to conceive, but fortunately their company has the perfect solution. A woman waits in a VR metaverse to do homework with her young daughter. In a care home staffed by advanced AIs, a woman struggles to make a connection with her android carer. Interference is a trilogy of near-future plays. Staged in an empty office block transformed with vivid projection and atmospheric soundscapes. It asks the question: will technology interfere with what we really need from each other?"

Etude de faisabilité de l'utilisation de molécules "cage" dans la dépollution des sols : solubilisation et extraction de polluants organiques par les cyclodextrines = Feasibility study of the application of complexing agents in soil flushing decontamination : enhancement solubilization and extraction of organic pollutants by cyclodextrins by Khalil Hanna( )

Soil matrices contaminated with polycyclic aromatic hydrocarbons (PAHs) abound at the sites of coke-oven gas plants, refineries, and many other major chemical industries. The problem of soil pollution has been widely recognised in recent years. The removal of PAHs from soil using pure water, via soil washing, is quite ineffective due to their low solubility and hydrophobicity. However, addition of cyclodextrin (CD) has been shown to increase the removal efficiency several fold. Herein are investigated the effectiveness of cyclodextrin to solubilise and to remove PAH occurring in industrially contaminated soil. The interactions in the cyclodextrin/pollutant/soil system have been studied “step by step”. The objective was to use a CD solution for soil flushing in column test in lab and to evaluate the influencing parameters that can significantly increase the removal efficiency. The process parameters chosen were CD concentration, ratio of washing solution volume to soil weight, and temperature of washing solution. These parameters were found to have a significant effect on PAH removal from the contaminated soil except the temperature where no significant enhancement in PAH extraction was observed for temperature range from 5 to 35 °C. Column experiments were also carried out to study the kinetics of PAH release from an aged-contaminated soil using three types of CD. The extraction results indicate that removal capacity of HPCD and MCD was higher than that of BCD. With 10% MCD solution, an extraction of about 40% of Phenanthrene on soil was observed, whereas only 0.2% was removed when water was used as the flushing solution

Formation of mixed Fe"-Fe"' oxides and their reactivity to catalyze chemical oxidation : remediation of hydrocarbon contaminated soils by Muhammad Usman( )

1 edition published in 2011 in English and held by 1 WorldCat member library worldwide

The main theme of this research is the use of reactive iron minerals in the remediation of hydrocarbon contaminated soils via chemical oxidation treatments at circumneutral pH. The contribution of this thesis is two-fold including the abiotic synthesis of mixed FeII-FeIII oxides considered as reactive iron minerals (magnetite and green rust) and their use to catalyze chemical oxidation. Oxidation methods tested in this study include Fenton-like (FL) and activated persulfate oxidation (AP). The formation of magnetite and green rust was studied by abiotic FeII-induced transformations of various ferric oxides like ferrihydrite, goethite, hematite and lepidocrocite. Then, the ability of magnetite was tested to catalyze chemical oxidation (FL and AP) for the degradation of aliphatic and polycyclic aromatic hydrocarbons (PAHs) at circumneutral pH. Significant degradation of oil hydrocarbons occurring in weathered as well as in crude oil was obtained by both oxidants. Magnetite catalyzed oxidation was also effective for remediation of two PAHs contaminated soils from ancient coking plant sites. No by-products were observed in all batch slurry oxidation systems. Very low hydrocarbon degradation was observed when soluble FeII was used as catalyst under the same experimental conditions. Magnetite also exhibited high reactivity to catalyze chemical oxidation in column experiments under flow through conditions. Oxidation studies revealed the importance of catalyst type for oxidation, PAHs availability in soils and the soil matrix effect. Results of this study suggest that magnetite can be used as iron source to activate both Fenton-like and persulfate oxidation at circumneutral pH. This study has important implications in the remediation of hydrocarbon polluted soils through in-situ chemical oxidation
Photo- et biotransformation de composés organiques des nuages. Cas du phénol et des acides aminés by Saly Jaber( )

1 edition published in 2020 in French and held by 1 WorldCat member library worldwide

Les nuages sont des systèmes multiphasiques complexes (gaz, liquide, solide) dans lesquels la matière organique dissoute est soumise à de multiples processus de transformation. La plupart des études se sont focalisées sur les réactions radicalaires, mais la découverte de microorganismes métaboliquement actifs dans les nuages a mis en évidence leur rôle potentiel en tant que biocatalyseurs dans la transformation des molécules organiques. L'objectif principal de cette thèse était d'évaluer le devenir de polluants (phénol, catéchol) et des acides aminés dans la phase aqueuse du nuage selon des transformations chimiques et microbiologiques. En ce qui concerne le phénol et le catéchol, les deux processus de transformation ont été décrits en se basant sur deux approches : expérimentale (microcosme simulant les conditions nuageuses) et modélisation (Box model). Les vitesses de bio- et photo-dégradation mesurées sont du même ordre de grandeur. Lorsque le système multiphasique est pris en compte, le modèle montre que le phénol est très majoritairement dégradé dans la phase gaz par des processus radicalaires, seul de catéchol, plus soluble, est transformé par les microorganismes (17%) et la chimie radicalaire (13%) en phase aqueuse. Pour les AA, les vitesses de transformations biotiques et abiotiques des acides aminés ont été également mesurées en microcosmes, pour ce faire une nouvelle méthode de LC-MS a été développée. Ces mesures ont été complétées par des calculs théoriques basés sur les constantes de réactivité. Les résultats sont complexes et montrent que les AA peuvent être dégradés mais aussi produits, les vitesses dépendent des AA mais aussi des souches microbiennes. Un travail complémentaire a été réalisé pour décrire le mécanisme de photo-dégradation du complexe Fe(III)-EDDS (EDDS : Ethylenediamine-N, N'-disuccinic acid) utilisé dans les microcosmes pour créer des radicaux OH. Ce mécanisme est basé sur l'identification structurale de 6 photo-produits par LC-MS

In recent decades, pharmaceuticals and personal care products (PPCPs) have emerged as a new environmental concern. Pharmaceuticals have been widely detected in ground water, surface water and even drinking water with a concentration ranging from ng to µg L-1 in wastewater effluents. Sewage treatment plants (STPs) cannot remove completely all pharmaceuticals due to their low concentration in water and resistance to biological degradation. In AOPs, the most frequently used methods include homogeneous reaction such as Fenton, Fenton like or Photo-Fenton process. In this work, composite catalyst BiOCl0.75I0.25 was synthesized by precipitation method under ambient pressure and low temperature followed with a series of characterization. Moreover, the adsorption and photocatalytic degradation abilities of new bismuth catalyst in water are tested under simulated solar light using Acetaminophen, p-hydroxyphenylacetic acid and as chemical pollutant
Réactivité de catalyseurs à base de cérium pour l'oxydation catalytique des colorants textiles en procédé Fenton/photo Fenton by Houeida Issa Hamoud( )

1 edition published in 2015 in French and held by 1 WorldCat member library worldwide

In this work, the parameters and mechanisms governing the reactivity of cerium based materials towards the degradation of textile dyes, taken separately or in binary mixture, in Fenton/photo-Fenton process have been investigated. For this purpose, five sets of catalysts were performed in order to determine the respective effects of : (i) the specific surface area of commercial CeO2 (SBET = 11, 101,5 ; 148 ; 235 and 284 m2/g); (ii) the zirconia doping ((CexZr1-xO2 with different Ce content (x = 0 ; 0,2 ; 0,5 ; 0,8 ; 1)); (iii) the treatment with H2SO4 ; and (iv) the impregnation of different metals in CeO2 (M = Ba, Bi, La, V and Mo). The textural, structural and chemical properties of the studied ceria-based materials were systematically characterized by nitrogen porosimetry, Raman, XRD, XPS, ATR/FTIR, DR-UV-Vis and TGA. Discoloration and mineralization kinetics of Orange II dye in presence of CeO2/H2O2 system are strongly related to the surface area of catalysts and other parameters (UV-Vis irradiation, pH, temperature, concentration of catalyst and H2O2). The presence of another dye with similar (Acid Green 25) or opposite charge (Malachite Green) can also influence the discoloration kinetics of Orange II. Comparing with single dye solutions, the degradation efficiency of both Orange II and Acid Green 25 were reduced in the mixture due to the competitive adsorption of both anionic dyes onto the same surface Ce sites. However, the discoloration of Malachite Green was enhanced in the presence of Orange II due to the simultaneous contribution of both coagulation/flocculation and Fenton-like process. It is suggested that a Malachite Green ion is electrostatically attracted by an Orange II ion at pH = 3. In addition, the performance of the mixed oxides in the heterogeneous Fenton process is strongly related to their textural, structural and chemical properties. Briefly, characterizations by XRD and Raman spectroscopy indicate that these nanosized mixed oxides can be considered as good quality solid solutions and possess structural properties consistent with the known phase diagram of CexZ1-xO2. The sulfation treatment mostly affects the Ce rich catalysts by increasing the crystallite size and lowering the specific surface area. The dissolution of ceria during sulfation followed by formation of Ce(SO4)2 amorphous phase on catalyst surface was investigated by UV-Vis and TGA analysis. Sulfation treatment as well as doping ceria with Zr increases the amount of reduced sites Ce (III) and defect sites.DR-UV-Vis, FTIR/ATR and Raman spectroscopic studies for adsorption and activation of H2O2 on mixed oxides show the formation of surface Ce-peroxo species as intermediate to generate hydroxyl radicals. The relative amounts of these species on the mixed oxides and/or not modified was indirectly determined using TPD-MS, giving rather good indication about the performances of catalysts towards the degradation of dye. The concentration of surface Ce, the density of defects Ce(III) sites (increased by doping and sulfation treatment) and the surface area appear to be among the most important parameters affecting the catalytic activity. Impregnation of ceria with different metals did not show a positive effect on the reactivity of this material in Fenton process. A possible mechanism for the activation of H2O2 was discussed in details according to all the experimental results and to the literature. From a mechanistic viewpoint, it is shown using FTIR/ATR and liquid UV-Vis spectroscopic measurements that the adsorption of the anionic dye is highly pH-dependent and proceeds via electrostatic interactions with surface metal centers. A possible pathway for Orange degradation is proposed on the basis of qualitative and quantitative detection of intermediate compounds, in liquid phase and on catalyst surface, using various techniques (FTIR/ATR, DR-UV-VIS, HPLC and GC/MS)
Oxydation par les ferrates d'un sol contaminé par du DNAPL en condition saturée : conséquences sur les Composés Aromatiques Polycycliques (HAP et CAP Polaires) : Expérimentations en batch et colonne by Clotilde Johansson( )

Soils encountered at former coking plant sites are often impacted by Polycyclic Aromatic Compounds (PAC) inherited from coal tar spillages. The remediation of the source zones is complex, particularly in the aquifer where Dense Non-Aqueous Phase Liquids (DNAPL) occur. This thesis is part of the BIOXYVAL project and focuses on the in situ chemical oxidation of residual tar, remaining in the saturated zone after pumping of the DNAPL. The objectives of this thesis were to study and compare the oxidative efficiency of ferrates with other oxidants to remediate a solid matrix spiked with DNAPL. This work aimed to (i) understand the global degradation mechanisms, (ii) evaluate the possible formation of hazardous oxygenated by-products (O-PAC) and (iii) identify the limitations for an in situ application. Two laboratory studies were conducted: batch experiments, ideal reactor and enclosed system, and column experiments under flow through conditions. Our works highlight (batches) the systematic production and accumulation of O-PAC ketones along oxidation with permanganate and ferrates (oxydo-reductive pathway), whereas oxidants following a radical mechanism do not show accumulation of those by-products. High degradation yields are measured with all oxidants tested (except the Fenton-like and the hydrogen peroxide). Permanganate and ferrates were then studied in column experiments. The limited reactivity of permanganate linked to the stability and low availability of the pollutants resulted on a poor efficiency of the oxidant under continuous flushing. The MnO2 precipitates did not have a high impact on porosity but seemed to reduce the availability of the pollutants during oxidation. Production of O-PAC were measured with lixiviated particles. In the contrary, ferrates injections induced a rapid clogging of the porous media, linked to the formation of ferric particles. Simultaneously, high remobilization of DNAPL drops was observed during the injections. Like permanganate, some O-PAC by-products were detected with lixiviated particles. The results demonstrate the ability of ferrates to degrade PACs from the DNAPL but show that their injection in situ is today impractical, as the technical and economic feasibility are not forthcoming. This work suggests considering the optimization of ferrates application and propose other solutions for the studied site

Réactivité des hydrocarbures en réponse à une injection de CO2/O2 dans des conditions de réservoirs pétroliers déplétés : modélisations expérimentale et numérique by Claire Pacini-Petitjean( )

1 edition published in 2015 in French and held by 1 WorldCat member library worldwide

The geological storage of CO2 (CO2 Capture-Storage - CCS) and the Enhanced Oil Recovery (EOR) by CO2 injection into petroleum reservoirs could limit CO2 atmospheric accumulation. However, CO2 can be associated with oxygen. To predict the hydrocarbon evolution under these conditions involves the study of oxidation mechanisms. Oxidation experiment and kinetic detailed modeling were carried out with pure compounds. The comparison between experimental and modeling results led to the construction of a hydrocarbon oxidation kinetic model and emphasized the parameters leading to auto ignition. The good agreement between our experiments and modeling are promising for the development of a tool predicting the critical temperature leading to auto-ignition and the evolution of hydrocarbon composition, to estimate the stability of a petroleum system in CO2 injection context
Développement de matériaux hybrides chitosan-montmorillonite pour la coagulation-floculation des eaux naturelles : de l'étude de la relation structure-réactivité en eaux modèles à l'application au traitement d'eaux de rivière by Julie Salvé( )

1 edition published in 2020 in French and held by 1 WorldCat member library worldwide

Le procédé de coagulation-floculation est une étape cruciale dans les filières de production d'eau potable. Les sels métalliques sont utilisés comme réactifs pour éliminer les particules en suspension, les colloïdes et la Matière Organique Dissoute (MOD) contenus dans les eaux de surface. Cependant, ils génèrent d'importantes quantités de boues difficilement valorisables. Bien que leurs propriétés floculantes soient reconnues depuis longtemps, les polymères bio-sourcés, comme le chitosan (CS), ne peuvent pas être considérés comme des alternatives viables en replacement de ces sels métalliques. Du fait de leur faible réactivité vis-à-vis des MOD et de l'apport en carbone organique dissous dans les eaux traitées provenant des polymères non réactifs, ils peuvent entrainer des dysfonctionnements dans les procédés situés en aval (colmatage des filtres, formation de sous-produits de désinfection). Dans ce manuscrit, l'association du chitosan avec des particules d'argile (Montmorillonite-MMT) a été étudiée afin de combiner les propriétés floculantes du biopolymère avec les capacités de sorption de l'argile pour former des flocs lestés et ainsi minimiser le relargage de CS dans les eaux traitées. Lors de l'optimisation de la préparation des hybrides CS-MMT dans l'objectif d'éliminer un composé modèle une relation structure-réactivité des hybrides a été démontrée. Le procédé de séchage, lors de la préparation des matériaux, s'est avéré être un paramètre-clé dans la stabilisation des hybrides sensibles à la minéralisation des eaux modèles et naturelles. L'application des hybrides optimisés pour le traitement de deux eaux de rivières (Vienne, Clain) a mis en évidence des différences de réactivité et de sélectivité entre les divers hybrides, FeCl3, CS et MMT. Les hybrides séchés ont ainsi présenté une meilleure élimination des composés de faibles poids moléculaires et peu hydrophobes tandis que les sels métalliques sont plus performants vis-à-vis des composés aromatiques, hydrophobes et de poids moléculaires élevés. Ces hybrides relarguant peu de chitosan résiduel dans les eaux traitées, leur performance peut être améliorée par une augmentation des doses de traitement
