This PhD student research project concerns the development and use of printable multifunctional materials, focusing on the trade-offs between material properties and application specification, with a particular emphasis on joule heating and electroluminescence functions. The originality of the work lies in a coupled approach between multifunctional materials and textile integration. The first part of the study concerned the selection of multifunctional materials deemed potentially interesting for the creation of intelligent textiles adapted to TESCA-groupe's target sectors. This involved characterizing the electrical and thermal properties of both the conductive materials and the textile substrate. In addition, analyses using scanning electron microscopy (SEM)/energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD) were carried out to study the microstructure, including adhesion, the thickness of the deposited layers and the chemical composition of the materials. The second aspect focused on an accelerated ageing study on unit specimens of textile substrates coated with conductive ink, in compliance with the specifications required by Tesca. The aim of this approach was to identify the inherent limitations of each material, such as maximum deformation, temperature variations, adhesion, process compatibility, etc., with a view to proposing areas for optimization or taking these limitations into account when designing transducers integrated on textile substrates. This first step enabled us to establish a base of multifunctional materials that could be used for specific applications, such as heating mats, capacitive or resistive switches, transducers, sensors for mechanical quantities, among others. The third aspect of this research consisted in assembling these basic elements to create sub-functions described as "intelligent". In fact, the production of transducers generally involved combining different multifunctional materials to meet the specific requirements of the target application

The presented thesis focused on the synthesis and photophysical investigation of luminescent Pt(II) complexes and their resulting assemblies that form upon aggregation. Multiple supramolecular motifs were utilized in order to gain control over the assembling behavior of the square-planar complexes. Crown-ether scaffolds were tethered with the phosphorescent metal complexes rendering a supramolecular switch that can be triggered by potassium cations. Moreover, alteration of the Pt(II)-stacking arrangement upon ligand coordination was exploited to realize a chemosensor that can be employed for of differential detection of aza-heterocycles. Furthermore, the installation of a H-bond motif to a luminescent Pt(II) complex was established, which resulted in a compound forming a two-dimensional organization on graphene. Finally, amphiphilic Pt(II) complexes were synthesized that self-assemble into highly luminescent aggregates in aqueous solutions. The series of water soluble neutral and negatively charged metal complexes were characterized with respect to their photophysical parameters and their interactions with virus coat proteins

This work deals with the stabilization of premixed turbulent swirling flames of methane/hydrogen/air combustible mixtures with different dilution rates of nitrogen and carbon dioxide. A central bluff body helps stabilizing the flames at low swirl numbers. The flame tip eventually impinges the combustor peripheral wall. The general objective is to gain understanding of the mechanisms governing the stabilization and the topology of these flames. It is found that the swirl number, the combustible mixture composition, the geometry of the combustor, and the thermal boundary conditions have a strong impact on the shape taken by these flames. The experimental setup used to characterize flames topologies is first described. Flames prone to topology bifurcations are selected and are studied for different arrangement of the combustor when the combustion chamber shape and size, the injection tube diameter, and swirl number are varied. One operating condition is fully characterized under non-reactive and reactive conditions using Planar Hydroxyl Laser Induced Fluorescence (OH-PLIF), Particle Imaging Velocimetry (PIV), and Laser Induced Phosphorescence of thermographic phosphors (LIP) to generate a detailed database of the flow and the corresponding boundary conditions. An analysis is then conducted to understand the mechanisms controlling shape bifurcations when the flame interacts with the combustor peripheral wall. Effects of the combustible mixture composition, the bulk flow velocity, and the swirl number are analyzed. It is shown that the transition from a V to an M flame is triggered by a flashback of the V flame tip in the boundary layer of the combustor peripheral wall. Dimensionless numbers controlling these transitions are identified and a simplified model is developed to help the prediction of the flame shapes. The physics of these shape bifurcations differs when the flame does not interact with the combustor wall. The large influence of the hydrogen enrichment in the fuel on the flame shape is analyzed using flame chemiluminescence and OH-PLIF. LIP and thermocouple measurements demonstrate that the thermal boundary conditions still have a strong impact on the flame topology. The combined effects of strain and heat losses are investigated using joint OH-PLIF and PIV experiments. It is shown that flammability limits of premixed flames are reduced due to heat losses and the transitions from M to V shaped flames is consecutive to localized extinctions of flame front elements located in the outer shear layer of the jet flow that are submitted to large strain rates. These experiments are completed by an analysis of the dynamics of methane/hydrogen/air flames. It is shown that low frequency and high amplitude velocity modulations generated by a loudspeaker alter the shape taken by these flames. The stabilization of methane/hydrogen/air flames diluted by nitrogen and carbon dioxide is finally examined. It was possible to stabilize swirled flames featuring important dilution rates due to the presence of the bluff body, installed on the axis of the injection tube. The recirculation zone behind this element supplies hot burnt gases to the flame anchoring point. Using OH* chemiluminescence imaging, it is shown than increasing the molar fraction of diluent in the fuel reduces the light emission from excited OH* radicals. The influence of dilution on the flame chemistry is emphasized with experiments conducted at a fixed thermal power and fixed adiabatic flame temperature. It is also demonstrated that the composition of the diluent has a strong influence on the temperature field of the burnt gases and of the combustor wall surfaces. Dilution with carbon dioxide increases radiative heat losses from the burnt gases in comparison to dilution with nitrogen. This penalizes the combustor efficiency equipped with four transparent quartz walls. [...]

The aim of the present thesis is to develop a novel experimental technique for determining the residence time distribution (RTD) of solid particles in solid unit operations as well as model development. Initially, a novel optical method was developed to measure the particle RTD. Experiments are carried out with Silicon Carbide (SiC) and the pigment phosphorescent (Lumilux® Green SN-F50 WS) as tracer particle. A preliminary experimental study was conducted in a simple bubbling fluidized bed in order to validate the proposed RTD measurement methodology. In the second step, the developed technique of the concentration measurement was applied to measure the RTD of a deep fluidized bed. The particle RTD curves are determined experimentally in different operating conditions. Finally, a model consisting of the combination of the ideal reactors is proposed to predict the particle residence time distribution in the studied fluidized bed. The predicted output values are then compared with the experimental data to establish a good model fitting data
