With support from the Division of Chemistry (CHE), and co-funding from the Division of Molecular & Cellular Biosciences (MCB) and the Established Program to Stimulate Competitive Research, Mississippi State University (MSU) will acquire and install a helium recovery system to support the MSU NMR Facility. Helium is a non-renewable resource, and the scientific instrumentation that relies on liquid helium (LHe) is linked to the status of the global helium supply. As a result of helium shortages, critical scientific infrastructure is in jeopardy, which puts the US researchers who rely on that infrastructure at risk of losing their competitiveness. Nuclear Magnetic Resonance (NMR) spectrometers require a constant supply of helium because of the superconducting coils that generate the high magnetic fields needed for those instruments. This makes NMR facilities acutely susceptible to fluctuations in the helium market. With a helium recovery system, the MSU NMR Facility will recycle nearly all of the helium it uses, assuring its continued viability and allowing it to serve new users by maintaining low user fees. The team is also developing a teaching unit on helium recycling and scarcity for MSU’s popular Environmental Chemistry class. Information on the installation process will be disseminated via the NMR facility’s website and YouTube channel. This will support the installation of helium recovery systems in other small NMR facilities like that at MSU. The proposed helium recovery equipment will support NMR equipment serving numerous chemistry and biology research projects throughout the region. Examples include synthesis of organometallic and inorganic chemicals used in novel catalysts, C-H activation, CO2 reduction, photocatalysis, and organic light-emitting diodes (OLEDs). The facility will also support research on biomolecular function, multifunctional materials, and novel polymers. NMR is a critical enabling technology to understand reaction mechanisms and molecular structure, and researchers throughout Mississippi, Alabama, Tennessee, and Louisiana will benefit from this equipment and the stability it will provide in facilitating the maintenance of a steady He supply in support of the regionally important NMR facility at Mississippi State University.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（MCB）的共同资助和刺激竞争性研究的既定计划，密西西比州立大学（MSU）将获取并安装氦恢复系统以支持MSU NMR NMR设施。氦气是一种不可再生的资源，依赖液态氦（LHE）的科学仪器与全球氦气供应的状态有关。由于氦短缺，危险的批判性科学基础设施受到危害，这使依靠该基础设施的美国研究人员面临失去竞争力的风险。核磁共振（NMR）光谱仪需要持续的氦气供应，因为超导线圈产生了这些仪器所需的高磁场。这使得NMR设施非常容易受到氦气市场波动的影响。使用氦气恢复系统，MSU NMR设施将回收几乎所有使用的氦气，确保其持续的生存能力，并通过维持低使用费用来为新用户提供服务。该团队还为MSU流行的环境化学课程开发了一个有关氦回收和稀缺性的教学部门。有关安装过程的信息将通过NMR设施的网站和YouTube频道传播。这将支持在MSU这样的其他小型NMR设施中安装氦恢复系统。拟议的氦恢复设备将支持为整个地区的众多化学和生物学研究项目提供服务的NMR设备。例子包括在新型催化剂中使用的有机和无机化学物质的合成，C-H激活，二氧化碳还原，光催化和有机光发射二极管（OLEDS）。该设施还将支持有关生物分子功能，多功能材料和新型聚合物的研究。 NMR is a critical enabling technology to understand reaction mechanisms and molecular structure, and researchers throughout Mississippi, Alabama, Tennessee, and Louisiana will benefit from this equipment and the stability it will provide in facilitating the maintenance of a steady He supply in support of the regionally important NMR facility at Mississippi State University.This award reflects NSF's statutory mission and has We were deemed honestly of support through evaluation using the基金会的智力优点和更广泛的影响评论标准。
