Research Project Title:
Studying Liquid Transport Through Small Diameter Carbon Nanotubes
abstract:As science continues to advance, there is always an emphasis on nanoscale processes — for example, nanoscale mass transport, which has been recently revolutionized by carbon nanotubes (CNTs). These are nearly one-dimensional hollow tubes with diameters ranging from approximately 0.5 – 10 nm. Currently, interactions between molecules and the exterior of the nanotube are relatively well studied; however, discoveries about the interactions with the interior of the tube remain to be made. The hollow geometry of CNTs make them permeable to ions and molecules of appropriate sizes. Currently, liquid flow through small diameter nanotubes is not well controlled, but being able to reliably flow molecules through single-walled carbon nanotubes (SWNTs) will have many applications such as micro-channels, small-scale drug delivery, nanoscale plug flow reactors, and more. Previous work proves that liquid filling in small-diameter tubes is possible and can be controlled. For this study, I intend to first study spontaneous water filling in carbon nanotubes by using Raman spectroscopy to track liquid movement. Then, I will attempt to control the flow of water through nanotubes using potential differences across tubes.
"I have been a UROP student for almost two full academic years. During this time, I have gained valuable knowledge in various areas of research, as well as experience in how to be a focused and efficient researcher. I am participating in this program because I believe I am ready for the responsibility of working on my own project, and the experience I will gain will be helpful as I pursue a PhD following graduation."
