With support from the Division of Chemistry, Professor Chekmenev at Wayne State University (WSU) is implementing a closed helium recovery system to sustain three shared research Nuclear Magnetic Resonance (NMR) instruments, one teaching NMR instrument, and a 7-Tesla Fourier Transform Ion Cyclotron Resonance Mass Spectrometer (FT-ICR MS). The instruments are used to identify and characterize molecules and are essential research tools. These instruments utilize high-field superconducting magnets that require liquid helium to maintain their fields. There is a global shortage of helium – a non-renewable natural resource – which has negatively impacted our ability to maintain these magnets. The helium recovery system will mitigate resulting uncertainty, enabling continuation of WSU research at the forefront of science in the fields of synthetic chemistry, biological chemistry, catalysis, food science, biomedical sciences and technology, microelectronics/sensing, and biomaterials.A closed-loop system will capture helium from the superconducting magnets associated with the NMR and mass spectrometry instruments in the WSU chemistry department facility. The collected gas will be temporarily stored in medium-pressure tanks before being liquified at a centralized station and then transferred to a separate mobile Dewar receptacle to be used for magnet fills. the recovery rate will be monitored and reported to NSF. A high rate of recovery is expected. The ability to recycle precious He to sustain the NMR and MS instruments at WSU Chemistry will help drive the recruitment and training of a diverse group of students as an integral part of the research and teaching missions of the department .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.

在化学系的支持下，韦恩州立大学（WSU）的Chekmenev教授正在实施封闭的氦恢复系统，以维持三种共享的研究核磁共振（NMR）仪器，一种NMR教学仪器和7台Tesla傅立叶变换型转换离子离子离子循环体共振质量光谱仪（FT-ICR MS）。这些仪器用于识别和表征分子，是必不可少的研究工具。这些仪器利用需要液态氦气维持田间的高场超导磁铁。全球氦气短缺 - 一种不可再生的自然资源，这对我们维护这些磁铁的能力产生了负面影响。 The helium recovery system will mitigate resulting uncertainty, enabling continuation of WSU research at the forefront of science in the fields of synthetic chemistry, biologic chemistry, catalysis, food science, biomedical sciences and technology, microelectronics/sensing, and biomaterials.A closed-loop system will capture helium from the superconducting magnets associated with the NMR and mass spectrometry instruments in the WSU化学系设施。收集的气体将暂时存储在中型压力箱中，然后再在集中式站清算，然后转移到单独的移动露水受体中以用于磁铁填充物。恢复率将受到监视并报告给NSF。预计回收率很高。他在WSU化学上维持NMR和MS仪器的珍贵能力将有助于推动招聘和培训一组潜水员的学生，这是该部门研究和教学任务不可或缺的一部分。该奖项反映了NSF的法定任务，并通过使用该基金会的智力功能和广泛的影响来评估NSF的法定任务。
