The traditional method of producing these films is by routinely dipping a negatively charged substrate into charged polyelectrolyte solutions. Another method, also demonstrated in the lab, is the Spin Grower, which was created by a previous ME 450 team. This process reduces the assembly time because it applies the solution to a rapidly spinning substrate. This project is an effort to improve the capabilities of the Spin Grower.<br/><br/>Description: Final report of Team 25 of ME450, Fall 2008 semester. http://hdl.handle.net/2027.42/62491 Title: A Novel Device for Tension-Torsion Testing of Micro-Wires<br/><br/>Authors: Fick, Thomas; Harrison, Paula; King, Kristin; Miller, Gretchen<br/><br/>Abstract: In the current era of micro and nanotechnology, the inability of the traditional laws governing permanent deformations to predict plastic behavior in small-scale devices is a critical issue. A driving force behind miniaturization is the idea that “smaller is stronger”. Some experiments have been completed to study the material properties of small-scale wires, but more experiments need to be done to verify the theory. Our team designed and built a miniature tension-torsion tester to be used for experimentation and validation. The system will be interfaced with a computer controller, which allows the user to define specific loading paths and to view the results graphically and numerically in real-time or instantaneously when the test is complete.<br/><br/>Description: Final report of Team 24 of ME450, Fall 2008 semester. http://hdl.handle.net/2027.42/62490 Title: A Desktop Reactor for Plasma-Enhanced Growth of Carbon Nanotubes<br/><br/>Authors: Nicholson, Kyler; Taphouse, John; Viswanathan, Janani; Yamasaki, Bryan<br/><br/>Abstract: There are many potential applications for vertically aligned carbon nanotubes (CNTs), including various microelectronic and micromechanical devices. Vertically aligned CNTs, especially single isolated CNTs, cannot be consistently grown using pure thermal chemical vapor deposition (CVD) system. However, recent research suggests that the addition of plasma to CVD systems can greatly enhance the probability of growing vertical CNTs.<br/><br/>Description: Final report of Team 23 of ME450, Fall 2008 semester. http://hdl.handle.net/2027.42/62489 Title: System for Dynamically-Controlled Growth of Hybrid Nanostructure Arrays<br/><br/>Authors: Coffer, Benjamin; Gozum, Murat; Shite, Eric; Zhang, Chenhao<br/><br/>Abstract: Carbon nanotubes (CNTs) and nanowires (NWs) have been applied in multiple fields due to their high strength, electrical conductivity, and optical properties. New types of nanostructure materials could be suitable for new applications. Our project is therefore to build a machine capable of growing two species of nanostructures on the same substrate. Currently, there exist multiple methods of growing nanostructures such as NWs and CNTs. However, little work has been done to combine methods and grow a hybrid structure.<br/><br/>Description: Final report of Team 22 of ME450, Fall 2008 semester.
