Solid-state NMR Spectroscopy of Next-Generation Materials
HEALTH, ENERGY & DEVELOPMENT
Evolving through the next decade of materials research will require cataclysmic shifts in balancing the advances of next-generation materials by optimizing function through physical properties in solids and decoding their underlying atomic- and molecular structure.
Our research area is to advance health and energy based materials using solid-state nuclear magnetic resonance (SSNMR) spectroscopy and dynamic nuclear polarization (DNP) NMR to elucidate the structure and dynamics of hybrid materials. As the population grows and ages across Canada and abroad, fundamental understanding of how the scientific community can improve our lives through materials is an essential step for future generations.
Our research facility is located within the Department of Chemistry at the University of Alberta. The solid-state NMR Facility for Solids houses three high field SSNMR spectrometers (300, 400 and 500 MHz), while the National Ultrahigh-Field NMR Facility for Solids (900 MHz) located in Canada’s capital Ottawa, Ontario provides additional research support for extremely challenging materials often encountered in our research program.
Some areas of interest include nanoporous materials (e.g., zeolites, MOFs, etc.), bioinspired materials (e.g., biomineralization, phosphosilicate glass-ceramics, etc.), hybrid organic-inorganic materials (e.g., functionalized nanoparticles, sol-gel, photovoltaics, etc.) and exploring approaches to study difficult NMR nuclei in solids.
