Advanced NMR methods for materials research

Nuclear Magnetic Resonance (NMR) spectroscopy is one of the most versatile methods in chemical analysis. The method provides information from molecular to macroscopic level and it can be used to study optically opaque materials. This thesis work explores interesting topical materials using advanced NMR methods for liquids and gases.

Thermal modification is an environmentally friendly process to improve the resistance of wood to weather. In this work, the changes in the microstructure of wood due to the thermal modification was studied by magnetic resonance imaging.

Ionic liquids are powerful solvents and electrically conducting fluids. Multidimensional Laplace NMR study provided detailed information about the structure and aggregation phenomena of a novel, less corrosive ionic liquid.

Shale gas is an important, alternative source of energy. The porous structures of shale and cement were investigated by using xenon gas as a sensitive probe.

Porous organic cages have shown extraordinary performance in selective separation of noble gases from gas mixtures. The structure of the cages was studied by combining NMR experiments of xenon and SF6 with computational modelling.

Overall, the NMR methods used in the study provided extraordinarily rich information about the structures of materials as well as dynamics of adsorbed fluids that cannot be obtained by traditional methods. The information provides means to optimize the properties of the materials for new applications.
