Doctoral Dissertations
The narrow hydrophobic interior of a carbon nanotube (CNT) poses a barrier to the transport of water and ions, and yet, unexpectedly, numerous experimental and simulation studies have confirmed fast water transport rates comparable to those seen in biological aquaporin channels. These outstanding features of high water permeability and high solute rejection of even dissolved ions that would typically require a lot of energy for separation in commercial processes makes carbon nanotubes an exciting candidate for desalination membranes. Extending ion exclusion beyond simple mechanical sieving by the inclusion of electrostatics via added functionality to the nanotube bears promise to not …

Development Of Microfluidic Platforms For Studies Of Cellular Organization In Escherichia Coli, Anna Dawn Jennings
Masters Theses
Traditionally, bacteria cells have been imaged on agarose pads allowing them to grow in steady conditions for only a few doubling times. To understand the cellular organization in bacteria, tools are needed that allow the observation of log-phase cells for many generations. In recent years, several microfluidic platforms have been designed that allow microscopic imaging of bacteria for over one hundred generations. One of the most promising approaches has been the so-called mother machine design where bacteria grow in small dead-end channels all connected to a large main channel, which is used to flow fresh nutrients to the cells and …
