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，准确测量纳米多孔材料上气体/蒸汽吸附的大小和动力学是评估用于各种分离、传感、催化或纯化应用的新材料的性能的重要步骤。随着对理解复杂环境下材料行为的重要性的重新关注，密苏里州科技大学（密苏里州ST）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。此次获得的系统将用于填补能源密集型分离、气体/生物气溶胶传感、尺寸选择性催化和碳捕获/利用等方面的基础知识空白。此次获得的重大研究仪器奖旨在获得一台动态混合气体/蒸汽吸附分析仪，该分析仪集成了动态采样质谱仪（VGS-DSMS）和自动突破反应器（ABR），称为VGS-DSMS-ABR套件。该套件-由于其能够执行各种类型的纳米多孔材料的二元和组合平衡动态表征-将推进与新材料设计和用作吸附剂，传感器，或催化剂在能源和环境过程中，通过提供评估吸附特性和建立性能的综合手段，纳米多孔材料的性能相关性。拟议的VGS-DSMS-ABR套件不仅将支持面向材料设计和性能优化的当前和未来的研究项目，而且还支持密苏里州ST和10个合作机构的教育，培训和推广活动。该奖项反映了NSF的法定使命，并已被认为是值得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的支持。

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.
