ABSTRACT Proposal No: CTS-9702239 Proposal Type: CAREER Principal Investigator: J. Karl Johnson Affiliation: University of Pittsburgh This CAREER grant is awarded through the Interfacial, Transport and Separations Program of the Chemical and Transport Systems Division. The objective of the proposal is to demonstrate the feasibility of using novel carbon nanotubules for advanced hydrogen storage systems. The calculations proposed will answer the question of whether carbon nanotubules are better suited for hydrogen storage than the best currently available commercial adsorbents. Phase diagrams, adsorption and desorption isotherms for hydrogen adsorbed in single tubules and in a honeycomb array of tubules, including the effect of adsorption in the tubule interstitial regions (where three tubules meet) will be computed. The amount of hydrogen adsorbed will be maximized as a function of tubule diameter over the range of operational temperatures and pressures. Hydrogen storage could be the first commercial application for carbon nanotubules. Possible applications of nanotuble based hydrogen storage systems include hydrogen powered vehicles, hydrogen transportation, gas separation, etc. Three main educational projects are also identified in the proposal (1) Development of web-based interactive instructional modules (2) Internet based learning and research for high school students (3) Participation in the Research Experience for Undergraduates program.

摘要 提案编号： CTS-9702239 提案类型：职业生涯主要研究者：J. Karl约翰逊附属机构： 匹兹堡大学 这项职业资助是通过化学和运输系统部门的界面，运输和分离计划授予的。该提案的目的是证明将新型碳纳米管用于先进储氢系统的可行性。提出的计算将回答碳纳米管是否比目前最好的商业吸附剂更适合储氢的问题。将计算在单个小管和小管蜂窝阵列中吸附的氢的相图、吸附和解吸等温线，包括在小管间隙区域（三个小管相遇的地方）中的吸附效应。在操作温度和压力范围内，吸附的氢的量将作为小管直径的函数而最大化。 储氢可能是碳纳米管的第一个商业应用。基于纳米管的储氢系统的可能应用包括氢动力汽车，氢运输，气体分离等三个主要的教育项目也确定在建议（1）基于网络的交互式教学模块的开发（2）基于互联网的学习和研究高中学生（3）参与本科生计划的研究经验。
