Low-temperature accessory for ultrahigh-field solid-state NMR experiments

Nuclear magnetic resonance (NMR) experiments allow researchers to gain insight into the structure and dynamics of molecules and materials with atomic-level precision. This proposal requests a reliable, cryogen-free air-jet cooler to enable NMR experiments on solid samples at low temperatures. This accessory is for the 900 MHz NMR spectrometer at Canada's National Ultrahigh-Field NMR Facility for Solids. The new low-temperature capabilities will result in increased sensitivity of the NMR experiment, and enable new research in diverse areas, since the Facility is used by dozens of scientists from across Canada. For example, research in the following areas will prosper: (i) characterization of chloride ion binding sites in ion channel mimics and inorganic materials; (ii) studies of clathrate hydrates and complex hydrides of importance to hydrogen storage technologies; (iii) studies of colossal thermal expansion in cobalt-based materials.
