Gated Chemical Transport through Vertically Aligned Carbon Nanotube Membranes
Presentation Materials | 08 Apr 2005 | Contributor(s): Bruce Hinds
A promising architecture for ion-channel mimetics is a composite membrane structure containing vertically aligned carbon nanotubes, with inner core diameters of 7 nm, passing across a polystyrene matrix film. Plasma oxidation during the fabrication process introduces carboxylic acid groups on the...

Computational Nanofluidics
Presentation Materials | 08 Apr 2005 | Contributor(s): Narayan Aluru
In this talk, I will present our recent results on computational analysis of electric field mediated transport of liquids and electrolytes in nanochannels.
The Network for Computational Nanotechnology (NCN) held a workshop entitled Challenges and Opportunities in the Development of Nanoelectromechanical Systems on April, 8, 2005. The workshop was held at the Entrepreneurship Center at Purdue University and featured presentations and discussion on current efforts to understand nanoscale phenomena that are expected to be important in the development of NEMS devices. The goals of the workshop was to bring together experimental and computational experts in the areas of nanofluidics, nanoelectronics, and thermal transport in nanoscale systems to present the results of their work, explore collaborative opportunities, and discuss strategies for developing NEMS devices.
