SGER: In-situ Investigation of Fluid Processes in a Carbon Nanotube

摘要CTS-0084272Y。控制管道中流体过程的过程是众所周知的，直径在微米及以上的范围内。随着直径的减小(例如，在几个纳米的范围内)，表面张力和毛细作用的作用已经被认为是改变的，以及它们对材料性质的依赖。因此，碳纳米管在技术应用中的预期前景迫切需要对这种作用力有充分的基本了解，特别是因为到目前为止还没有收集到一致的实验数据。借助电子能谱，PI在测定纳米管中的液/汽相分布方面取得了初步的结果。在此基础上，他提出开发一个实验计划，该计划将尽可能彻底地探索在许多纳米管情况下相界面的各个方面。我们将研究新开发的封闭式纳米管的特殊情况。这样的工作应该为根据精确的实验观测建立模型提供一组宝贵的数据。

AbstractCTS-0084272Y. Gogotsi, University of Illinois at ChicagoThe processes which govern fluid processes in pipes are well understood for diameters in the range of micrometers and above. As the diameters diminish ( e.g. in the range of a few nanometers), the role of surface tension and capillarity is has been seen to change, as well as their dependence on material properties. Thus, the expected promise of Carbon nanotubes in technological applications is in urgent need of a well documented basic understanding of such forces, especially since no consistent experimental data have been collected so far. The PI has obtained preliminary results in the determination of the liquid/vapor distribution in nanotubes, with the help of transmission electron spectroscopy. On that basis , he offers to develop an experimental program which will explore as thoroughly as possible the various aspects of phase interfacing in a number of nanotube situations. The special case of the newly developed closed nanotubes will be examined . Such work should offer a precious set of data for the elaboration of a model based on precise experimental observations.
