With support from the Division of Chemistry (CHE), and co-funding from the Division of Molecular and Cellular Biosciences (MCB), Professor Garrett and his colleagues at California State University, Northridge (CSUN), are adding a liquid helium recycling plant to the department’s nuclear magnetic resonance (NMR) instruments used in faculty and student research as well as in teaching numerous undergraduate and graduate classes. Helium gas is a non-renewable resource that is condensed to a supercold liquid needed to cool CSUN’s NMR instruments and enable study a broad range of organic and biochemical molecules. The recycling plant will collect the helium gas that evaporates from two NMR instruments, then condense and reuse it. The recycling system will reduces the need to purchase liquid helium, and so reduce costs and contribute to the preservation of purified He, a precious natural resource, for long-term usage.The CSUN Department of Chemistry and Biochemistry has three NMR spectrometers, two of which (multinuclear 400 MHz and 600 MHz instruments) are located close to each other and so are amenable to sharing recycling technology. The helium recycling system will reduce the Department’s 800 liter/year helium consumption by up to 70%, assuring continued faculty and student access to the instruments. In addition to supported research, this will enable continued incorporation of critical NMR experiments into several core classes, including organic chemistry, organic synthesis, inorganic chemistry and an in-depth organic analysis elective. CSUN is a large, Hispanic-serving university, that also provides academic opportunities to a significant number of first-generation students. Most undergraduates and all graduate students engage in research and approximately half of the department’s faculty need NMR data for their research programs. These include chemists and biochemists focused on organic synthetic methodology, natural product synthesis, battery and hydrogen technology, the biochemistry of protein chaperones, and biologically active compounds. As such, the helium recycling plant will add significant value to the department's dual teaching-research mission.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

在化学系 (CHE) 的支持以及分子和细胞生物科学系 (MCB) 的共同资助下，加州州立大学北岭分校 (CSUN) 的 Garrett 教授和他的同事们正在为该系的核磁共振 (NMR) 仪器用于教师和学生的研究以及众多本科生和研究生课程的教学。氦气是一种不可再生资源，可凝结成超冷液体。冷却 CSUN 的 NMR 仪器并能够研究各种有机和生化分子。回收工厂将收集从两台 NMR 仪器蒸发的氦气，然后将其冷凝和再利用。回收系统将减少购买液氦的需求。 ，从而降低成本并有助于保存纯化的He这种珍贵的自然资源以供长期使用。CSUN化学与生物化学系拥有三台核磁共振波谱仪，其中两台（多核 400 MHz 和 600 MHz 仪器）彼此靠近，因此可以共享回收技术。氦回收系统将使该系每年 800 升的氦消耗量减少高达 70%，从而确保教职员工和学生能够继续使用。除了支持的研究之外，这还将继续将关键的核磁共振实验纳入几个核心类别，包括有机化学、有机合成、无机化学和深入的研究。 CSUN 是一所大型的西班牙裔大学，它还为大量第一代学生提供学术机会，大多数本科生和所有研究生都从事研究，并且该系大约一半的教员需要 NMR 数据。其中包括专注于有机合成方法、天然产物合成、电池和氢技术、蛋白质分子伴侣的生物化学和生物活性化合物的化学家和生物化学家，因此，氦回收工厂将为该领域增加重大价值。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
