Full textPlasma surface modification is a widely used technique for improving the surface properties of polymers through the introduction of different functional groups. In the current research project, different methods to improve the characterization techniques of N2 and N2-H2 microwave discharge were investigated with the aim of optimizing the plasma surface process. First of all, a number of plasma parameters were measured at different process conditions. To determine the plasma parameters, optical emission spectroscopy was used not only within the well-documented UV-Visible region but also within the rarely studied infrared zone. Using infrared optical emission spectroscopy is advantageous as it eliminates the strong overlap between atomic and molecular transitions as well as the low intensity UV-Visible emission spectroscopy limitations. In the next step, the PTFE surface chemical composition was analyzed via XPS to quantify the concentrations of carbon, fluorine, and nitrogen after a plasma treatment in a N2-H2 gaseous environment. The XPS analyses were also performed after chemical derivatization to quantify the surface concentration of amino groups (%NH2) at different process conditions. The above-mentioned results were used to correlate process conditions and microwave N2-H2 discharge parameters to the chemical composition of the modified PTFE. The purpose was to determine the external plasma parameters and species present within the plasma which play a key role in the introduction of amino groups to the polymer surface. Furthermore, a mathematical model was developed using the Partial Least Squares Regression, (PLSR) using custom scripts written in MATLAB. A data set of input variables including the process conditions and plasma parameters for each experiment were generated along with the corresponding response matrix which in turn contained the surface properties of the film. The resulting database was used to build the relationship between the plasma parameters, process condition and the resulting film surface chemistry. This ultimately enabled to predict the PTFE surface chemistry from data originating from the plasma, without having to proceed to post-plasma surface characterization.

Full textDioxygen delignification considerably reduces the operating cost of the bleaching process and decreases the environmental impact of the bleaching effluent. Unfortunately the performance of dioxygen delignification is limited since part of the residual lignin is not reactive toward dioxygen while cellulose depolymerisation occurs. Studies suggested that dioxygen delignification could be improved thanks to the use of catalysts such as copper(II)–phenanthroline type complexes which have shown promising results on delignification efficiency. However cellulose was also more degraded. Different polypyridinyl ligands have been studied in this work, in an attempt to find copper(II) complexes that have more affinity toward lignin and less toward cellulose. Complexes have been characterised by UV/Vis spectroscopy, cyclic volammetry, and they were studied for the catalysed oxidation of various substrates: a non phenolic lignin model compound and lignocellulosic substrates (a model of cellulose, a model of native lignin and an industrial kraft pulp). It has been shown that the nature of the ligand had a significant effect on the catalytic activity of Cu(II) complexes in the oxygen oxidation of the lignin model compound. However, the active complexes only show a limited activity during the delignification of a kraft pulp and oxidize carbohydrates. This lack of selectivity prevents from an industrial application for paper pulp production but may be useful for the design of products with fewer constraints on cellulose polymerization degree

Full textThe particular environment within the porous structure of zeolites allows these materials to act as micro-reactors to optimize the photoreactivity of adsorbed molecules. In this context, we report the reaction mechanisms occurring after photoionization of t-stilbene confined into crystals of ZSM-5 zeolites of different sizes and morphologies. In the micro and nanocrystals of ZSM-5, the photoinduced cation radical evolves into a very stable charge transfer complex (CTC), formed by the ejection of an electron and stabilized by a compartmentalization process. In nanosheets, the cation radical is the stabilized species because the ejected electron cannot be trapped far enough from the cation radical to allow the formation of the CTC. Finally, in nanosponges, CTC is not formed and the lifetime of the radial cation is reduced to a few hundred µs. The case of anionic species formation was also studied. Thus, in aluminized MZSM-5s (M = H+, Na+ and Cs+), the photoexcitation of the incorporated 1,4-dicyanobenzene leads to the formation of an anion radical (RA) thanks to the zeolite donor character, whereas in silicalite-1, the Al-free MFI analogue, this reaction does not occur. In particular, nanosecond UV-vis spectroscopy highlighted the key role of aluminum and the influence of the charge-compensating cation on the lifetime of the RA. The activation energies required for the recombination of the electron of the anion radical with the positive electron hole created in the zeolite were determined and discussed. Finally, the work carried out on the study of the primary steps of charge separation processes in the case of the 9,10-dicyanoanthracene (DCA) molecule crystallized on the surface of ZSM-5 zeolites by photon counting (TCSPC) and femtosecond IR absorption spectroscopy techniques showed the ultrafast and quasi-simultaneous formation of the excited S1 singlet state, a state of charge transfer and excimer forms whose distribution depends on the polymorphism of the DCA crystal on the external surface of the zeolite.

Full textThe field of bioenergetics concerns the study of exchange and transformation of energy in living organisms. This manuscript proposes an electrochemical and spectroscopic study of the fourth complex of the respiratory chain, the terminal oxidases. The aim of this study was to understand the influence of some properties of these enzymes (potential of the cofactors, pH dependency…) on the catalytic mechanism. The first part describes an immobilization procedure which retains the protein activity and structure. This procedure has been applied for the study the inhibition of the proton pathways of cytochrome aa3 oxidase from P. denitrificans and shows the importance of proton transfer on the oxygen reduction. In a second study, two isoforms of cytochrome cbb3 oxidase were compared. No differences were observed between them until now. Our electrochemically induced FTIR spectroscopy study suggests the implication of different acidic residues during the redox reaction implying differences in the mechanism of these enzymes. The last part deals with the comparison of terminal oxidases of different types and shows the influence of the relative order of the midpoint potentials of the hemes on the oxygen reduction

Full textPhotoreversible photochromic compounds are currently of considerable interest from the point of view of their potential applications as molecular switches and for data storage and processing. The main target of the present investigation is to evaluate the scope and limitations of 3--(2--benzylbenzoyl)--4--quinolones as a photoreversible photochromic system. In order to investigate the relationship between quinolone chemical structures and photochemical behavior, a large series of new 3--(2--benzylbenzoyl)--4--quinolones with different substituents has been prepared using known as well as newly elaborated synthetic procedures. In the second part of the work a series of simpler photoenolizable 2--benzyl--3--benzoyl quinolones is studied by the means of fitting their UV--Vis absorption spectra and comparison with the results of quantum mechanical calculations at the TD DFT level. It was concluded that the mechanism of the reverse reaction involves ionization of the strongly acidic photoenols via protonation of the solvent molecules. The third part of the work includes investigation of the new quinolone derivatives. From the analyses of their absorption spectra and the results of quantum mechanical calculations, we propose a tentative mechanism, according to which the photoinduced hydrogen transfer yields a biradical, capable of cyclization into the hydroxy substituted dibenzo[b]acrydinones. This mechanism accounts for the observation that the nature of substituents in positions 1 and 2, the temperature and the presence of oxygen strongly affect regio-- and stereoselectivity of the cyclization
