MRI: Track 1 Acquisition of Dynamic Mixed Gas Sorption Analyzer-Mass Spectrometer to Enable Advanced Separation, Sensing, and Catalysis Research

在不同的操作条件下，准确测量气体/蒸汽在纳米多孔材料上的吸附大小和动力学是评估用于各种分离、传感、催化或提纯应用的新材料性能的关键步骤。随着对了解材料在复杂环境下行为的重要性的重新关注，密苏里州科技大学(密苏里州S和密苏里大学)的研究人员获得了能够在纳米多孔材料上吸附多组分气体/蒸汽的仪器。收购的系统将用于弥合与能源密集型分离、气体/生物气溶胶传感、尺寸选择性催化和碳捕获/利用相关的基础知识空白。这项重大研究仪器奖是获得动态混合气体/蒸汽吸附分析仪，集成了动态采样质谱仪(VGS-DSM)和自动突破反应堆(ABR)，称为VGS-DSM-ABR套件。由于其能够对各种类型的纳米多孔材料进行二元和组合的平衡-动态表征，该套件将通过提供评估纳米多孔材料的吸附特性和建立性能-性能关联的综合手段，促进与新材料的设计和在能源和环境过程中用作吸附剂、传感器或催化剂的现有材料的性能优化相关的研究。拟议的VGS-DSM-ABR套件不仅将支持当前和未来的研究项目，面向材料的设计和性能优化，还将支持密苏里州S和T；T；以及10个合作伙伴机构的几项教育、培训和推广活动。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

Accurate measurement of the magnitude and dynamics of gas/vapor sorption on nanoporous materials under diverse operating conditions is an essential step in evaluating the performance of new materials used in various separation, sensing, catalytic or purification applications. With renewed focus on the importance of understanding materials behaviors under complex environments, the researchers at Missouri University of Science and Technology (Missouri S&T) to acquire instrumentation that enables multicomponent gas/vapor sorption over nanoporous materials. The acquired system will be used to bridge fundamental knowledge gaps relevant to energy-intensive separations, gas/bio-aerosol sensing, size-selective catalysis, and carbon capture/utilization.This Major Research Instrumentation award is to acquire a dynamic mixed gas/vapor sorption analyzer, integrated with a dynamic sampling mass spectrometer (VGS-DSMS) plus an automated breakthrough reactor (ABR), called VGS-DSMS-ABR suite. The suite – owing to its ability to perform binary and combined equilibrium-dynamic characterization of nanoporous materials of various types – will advance research in many areas relevant to design of new materials and performance-optimization of existing materials used as sorbents, sensors, or catalysts in energy and environmental processes by providing a comprehensive means of assessing sorption characteristics and establishing property-performance correlations for nanoporous materials. The proposed VGS-DSMS-ABR suite will not only bolster current-and-future research projects geared towards design and performance-optimization of materials, but also support several education, training, and outreach activities at Missouri S&T and 10 partner institutions.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.
