Gravimetric Analyzer fo Gas Sorption Studies

摘要提案标题：重量分析仪到气体吸附器提案编号：CTS-0417861主要研究者：伊娃Marand机构：弗吉尼亚理工学院和州立大学本提案的目标是确保购买伊加重量分析仪的资金，这将使PI能够准确测量纳米复合膜中气体和蒸汽吸附的幅度和动态。这样的吸附信息将补充渗透数据已经在实验室中获得与现有的恒容渗透装置。总之，这两个独立的实验将使PI辨别纳米复合膜中的传输机制，从而促进对异质材料中气体传输的基本理解，并允许针对特定应用的纳米复合膜的有效设计。研究项目将直接受益于重量分析仪的收购，包括聚合物/沸石混合基质材料的开发和表征，用于气体分离应用的聚合物/纳米层铝磷酸盐和聚合物/碳纳米管复合膜，以及用于传感器，膜和催化的聚合物/倍半硅氧烷纳米复合材料。这些都是多研究者项目，涉及弗吉尼亚理工大学的教师以及其他机构的教师，所有人都可以使用这种仪器。就更广泛的影响而言，重力分析仪的提供将促进与这些研究项目有关的各种教育和外联活动。

AbstractProposal Title: Gravimetric Analyzer to Gas Sorption StudiesProposal Number: CTS-0417861Principal Investigator: Eva MarandInstitution: Virginia Polytechnic Institution and State UniversityThe goal of this proposal is to secure funding for the purchase of an IGA Gravimetric Analyzer, which would enable the PI to accurately measure the magnitude and dynamics of gas and vapor sorption in nano-composite membranes. Such sorption information would complement permeation data already obtainable in the laboratory with an existing constant-volume permeation apparatus. Together, these two separate experiments would allow the PI to discern the transport mechanism in nano-composite membranes, thus promoting a fundamental understanding of gas transport in heterogeneous materials and permitting efficient design of nano-composite membranes for specific applications. Research projects, which would directly benefit from the acquisition of the gravimetric analyzer, include the development and characterization of polymer/zeolite mixed matrix materials, polymer/nano-layer-aluminophosphate and polymer/carbon nanotube composite membranes for gas separation applications, as well as polymer/silsesquioxane nanocomposites, for applications in sensors, membranes and catalysis. These are multi-investigator projects, involving Virginia Tech faculty as well as faculty from other institutions, all of whom would have access to this instrument. In terms of the broader impacts, the availability of a gravimetric analyzer would promote the various educational and outreach activities, which are associated with these research projects.
