Full textIn this thesis, we propose innovative solutions for thermal management using vanadium dioxide (VO₂), a material with a metal-insulator transition (MIT), to design multilayer coatings whose radiative properties are fully controlled by temperature, without requiring any external energy input.After studying the validity of Kirchhoff's law to predict the thermal emission of anisothermal structures, we propose an innovative design for a VO₂-based glazing system to address the issue of thermal management in buildings. This glazing, self-regulated by the greenhouse effect and the presence of VO₂, demonstrates excellent thermal insulation performance while maintaining good transmission properties in the visible spectrum.Next, we designed, fabricated, and characterized a multilayer coating based on VO₂ for thermal switch applications. This coating exhibits an infrared emissivity opposite to that of bulk VO₂ and is capable of emitting significant heat flux above the critical temperature of VO₂, while emitting much less below this temperature. This type of thermal switch with positive differential emissivity paves the way for numerous applications in radiative cooling and thermal protection

Full textMerocyanines derive from the spiro bond cleavage of photochromic spirooxazines. Although merocyanines are generally unstable, appropriate conditions can stabilize them. Two series of spirophenanthrolinoxazines and spironaphthoxazines bearing the O-Alk chain in position 5 have been studied. According to their structures, different techniques allow to open the spiroform and to stabilize the merocyanine. For spirooxazines of phenanthroline series, the merocyanine content raises significantly with the solvent polarity. For spironaphthoxazines, protonation turns the solution red and negative photochromism has been observed under visible light irradiation. Numerical modelling has been applied to analyse the recorded data within the two series. Several interesting photochromic parameters have been determined. The investigated properties have great potential applications for future specific sensors or logic elements

Full textIn this work, we have prepared organophosphorated ligands based copper(I) or gold(I) dimers that act as efficient molecular clips thanks to metallophilic interactions. Firstly, a bimetallic copper(I) complex bearing bis(2-pyridyl)phosphole ligands was used as a molecular clip to organize monotopic cyano-capped pi-systems carrying various pi-conjugated fragments into self-assembled pi-stacked dimers. These dimers organized in the solid state within infinite columnar pi-stacks. Secondly, a bimetallic gold(I) complex bearing a biphosphole ligand was used as a molecular clip to organize ethynyl-capped [6]helicene moieties into self-assembled dimers. These dimers showed an enhancement of the chiroptical properties as compared to the free ethynyl[6]helicene ligand. Thirdly, a bimetallic copper(I) complex bearing 1,1-bis(diphenylphosphino)methane (dppm) ligands has revealed a powerful molecular clip to design self-assembled supramolecular architectures by reaction with different cyanometallates. These supramolecular derivatives have different topologies and are emissive in the visible spectrum upon UV excitation and in some cases they showed intriguing thermochromic luminescence properties

Full textThis PhD thesis work based on the synthesis and studie of fonctionnal organized elastomers and their precursors. We axed our studies to two families: liquid crystals and diacetylenes. In both case photopolymerisable monomers have been synthetized. In a first part, we have been elaborated elastomers precursors from laterally affixed liquid crystals nematic and/or cholesteric with wich we have obtained sensors polymers. Photochemical and chemical (hydrosilylation) ways have been used. In a second part, diacetylenes polyurethanes have been developped showing interesting thermochromic properties whereas diacetylenes liquid crystals synthetized

Full textWhen colonizing the digestive tract of monoxenic rats, Ruminococcus gnavus E1, isolated from human feces, produced a trypsin-dependant anti-Clostridium perfringens bacteriocin, RumC. LEM 9-17, able to produce RumC in vitro, was generated by random mutagenesis. RumC was purified from E1-monocontaminated caecal content and LEM 9-17 culture supernatant. In both cases, 2 fractions, the 1st one containing a 4235Da peptide, and the 2nd one two peptides of 4324Da and 4456Da were identified. The N-terminal sequence of the peptides present in both fractions was highly homologous, but Edman degradation reaction was blocked after the 11th residue. Three non identical structural genes encoding pre-RumC, 2 coding for radical SAM enzymes and 8 with predicted functions in biosynthesis, secretion, regulation and immunity were identified on a 13,5 kb region of E1 chromosome. Moreover, the rumC-like genes were shown to be widely disseminated among the human fecal microbiota with a high conservation rate
