Novel apparatus for Dynamic Nuclear Polarization (DNP) to open new frontiers of industrial applications of Nuclear Magnetic Resonance (NMR.)

Abstract (English)

This proposal has a dual objective: the development of Dynamic Nuclear Polarization (DNP) to enhance Nuclear Magnetic Resonance (NMR) in solids and in liquids. (1) In solids, new DNP apparatus will open new frontiers for industrial research focusing on the characterization of surfaces, in particular for research and development of surface chemistry to improve heterogeneous catalysis, to optimize surface coating, to enhance new electrode materials, etc. (2) In liquids, new apparatus for DNP will allow industrial applications of NMR of elements such as Silver-109, Iron-57 and Ytrrium-89 that have so far been difficult to study by lack of sensitivity. These developments require sophisticated apparatus for solid-state NMR at low temperatures (ca 100 K), gyrotrons for the generation of intense microwaves between 263 and 523 GHz, suitable wave-guides to carry microwaves from gyrotrons to NMR magnets, and the optimization of suitable stable paramagnetic radicals. The research and development will be conducted in close association of a team at EPFL and Bruker Biospin.
