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.

核磁共振（NMR）实验使研究人员能够以原子级的精度深入了解分子和材料的结构和动力学。 该提案要求可靠的无冷冻剂空气喷射冷却器，以使固体样品在低温下进行NMR实验。 该附件适用于加拿大国家固体超高场NMR设施的900 MHz NMR光谱仪。 新的低温能力将提高核磁共振实验的灵敏度，并使不同领域的新研究成为可能，因为该设施被来自加拿大各地的数十名科学家使用。 例如，以下领域的研究将蓬勃发展：（一）离子通道模拟物和无机材料中氯离子结合位点的特性;（二）对氢储存技术具有重要意义的笼形水合物和络合物的研究;（三）钴基材料的巨大热膨胀研究。
