Microbobines et RMN en phase solide

Abstract : This PhD thesis, at the interface between chemistry and physics, uses Solid State Nuclear Magnetic Resonance (ssNMR) for both exploiting diversity of materials and developing new easy-to-implement methodologies. ssNMR has proved to be really efficient to study materials and especially their interface by precisely characterising chemical environment of studied nuclei [1]. However, the main drawback of this technique is its lack of sensitivity, each analysis requiring 30 to 400 mg of sample. Such an amount is particularly difficult to obtain for sol-gel thin-film layers or for biological studies like Kidney stones. In order to solve this issue, the MACS (Magic Angle Coil Spinning) technique has been recently developed [2]. It consists of a micro-scaled coil surrounding a capillary containing the sample. Only 30 to 100 µg of material is necessary. As the microcoil is placed inside the usual solid state NMR rotor, no probe modification is needed. [1] C. Bonhomme, C. Gervais, and D.
