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.

在化学划分（CHE）的支持下，并获得了分子和细胞生物科学司（MCB）的共同资助，加勒特教授及其同事在加利福尼亚州立大学诺斯里奇（CSUN）的同事中，正在为部门的核磁共振仪（NMR）培养物和培训研究中的研究及其在许多人的研究中添加了液体氦气回收植物。氦气是一种不可再生的资源，它凝结为冷却CSUN NMR仪器所需的超冷液体，并使研究多种有机和生化分子。回收厂将收集从两种NMR仪器中蒸发的氦气，然后将其凝结并重复使用。回收系统将减少购买液态氦气的需求，从而降低成本并有助于保存纯净的自然资源，以供长期使用。CSUN化学和生物化学系具有三个NMR光谱仪，其中两个（跨核400 MHz和600 MHz乐器）与彼此相关的是，其中两个NMR光谱仪与彼此相关。氦气回收系统将使该部门的800升/年氦气消耗量最多减少70％，从而确保继续教师和学生使用该乐器。除了支持的研究外，这还可以继续考虑到关键的NMR实验分为几个核心类别，包括有机化学，有机合成，无机化学和深入的有机分析选修课。 CSUN是一所大型西班牙裔美国人大学，也为大量第一代学生提供了学术机会。大多数大学生和所有研究生都从事研究，该系的大约一半需要NMR数据来进行研究计划。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，蛋白质链蛋白链蛋白链的生物化学以及生物活性化合物的化学家和生物化学家。因此，氦回收厂将为该部门的双重教学教学任务增添重要价值。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响审查标准，认为通过评估被认为是珍贵的支持。
