Texto completoAn important number of molecular systems of biological interest like proteins cannot be studied by x-ray diffraction or liquid-state nuclear magnetic resonance methods because of lack of single crystals or intrinsic insolubility. Solid-state NMR spectroscopy offers the potential to provide precious information about the secondary structure of proteins, protein-protein interactions, folding and internal dynamics. Extensive solid-state NMR studies have been done on microcrystalline proteins, amyloid fibrils, membrane proteins or micelle-protein suspensions. Yet methodological developments in sample preparation of microcrystalline proteins, as well as further development in high-resolution solid-state NMR techniques are necessary. This thesis focuses on a number of structural, motional and methodological aspects encountered in the studies of biomolecules by solid-state NMR. An insight into the structural and motional features of C-terminal domain of the Human Centrin 2 (C-ter HsCen2) complex in a microcrystalline state is presented in the first part of the dissertation. In the second part, it is shown how one- and two-dimensional solid-state NMR experiments can help to disentangle spectral features in systems containing a mixture of different crystallographic forms with crystallographically inequivalent molecules in the unit cell of L-arginine hydrochloride. Polymorphism of L-glycine samples obtained by laser-induced crystallization methods is also studied. The final chapter presents an approach for removing the intrinsic asymmetry of 2D solid-state homonuclear correlation spectra of uniformly labelled biomolecules by equilibrating the magnetization in the initial stage of exchange experiments. It is also shown that the requirements needed for symmetrising the 2D exchange spectra are similar to the requirements needed to record quasi-quantitative cross-polarization magic-angle spinning spectra

Texto completoThis thesis deals with the recoupling and decoupling of dipolar homonuclear and heteronuclear interactions in solid-state NMR.First, two kinds of techniques for establishing the through-space correlations between quadrupolar nuclei and spin 1/2 nuclei are presented. One is MPCP (Multiple-pulse Cross-Polarization) recoupling sequence and the other one is D-HMQC (Dipolar assisted- Heteronuclear Multiple Quantum Coherence) sequence. We evaluate different kinds of dipolar recoupling techniques such as SFAM, SR41², that are used in our D-HMQC. Second, we propose a new 1H homonuclear dipolar decoupling technique labeled SAM (Smooth Amplitude Modulation). This method that is a symmetry-based sequences, works mainly at fast or ultra-fast Magic Angle Spinning (MAS) rates (vR > 25 kHz) and is complementary to previous methods, such as DUMBO, FSLG/PMLG. Third, a novel symmetry-based homonuclear recoupling method (SPIP) that excites double-quantum (DQ) coherences between spin-1/2 nuclei, such as 1H, is presented. Compared to previous 1H DQ-recoupling techniques, this pulse sequence requires moderate rf field, even at ultra-fast MAS speed. Furthermore, it displays higher robustness to both chemical shift anisotropy and spreads in resonance frequencies.Fourth, a new processing scheme, called covariance, is employed in solid state NMR to produce homo-nuclear correlation (HOMCOR) 2D spectra. It can accommodate signal truncation much better than the usual 2D-FT data treatment, without any previous knowledge of the positions and line-widths of the resonances. Besides, covariance methods can be applied to HETCOR NMR data to generate two HOMCOR indirect-covariance spectra

Texto completoThe aim of this thesis is to enhance the thermomechanical properties of PET fibers trialkoxysilane end-group crosslinking (hydrolysis-condensation) after the functionalization the alcohol and acid PET end-groups with bifunctional reagents. OH groupes were reacted with anhydride or isocyanate and COOH groups with epoxide. Reaction kinetics were studied by NMR on end-group model compounds. During melt modification many degradation and side reactions were observed and crosslinking occurred after hydrolysis-condensation. Thus we preferred to study the solid-state functionalization by diffusion of reagents at temperatures below 256°C. After solid-state modification, crosslinking finally occured giving maximum gel contents of 70°C. Mechanical properties of partially crosslinked samples were maintained up to 320°C
