  1. Measurement of CNT Based Fibers and Cavities Holly Tourtillott University of Missouri • Faculty Advisor: Dr. Uche Wejinya Graduate Student Advisor: Zhuxin Dong Department of Mechanical Engineering, University of Arkansas May 29, 2009 Micro and Nano Systems Engineering Laboratory, University of Arkansas

  2. Outline • Carbon Nanotubes • Objectives • Microelectrode Chip • Measurement of NanoCavities and Fiber Electrodes • Measurement Result • References Micro and Nano Systems Engineering Laboratory, University of Arkansas

  3. Carbon Nanotubes • Seamless hollow cylinder with diameter of approximately one to fifty nanometers • Can be basically divided into two kinds: Single walled and multi walled • Are the strongest and stiffest materials yet discovered in terms of tensile strength and elastic modulus respectively • Used in solar cells, electrical circuits, ultracapacitors, and often used as a vessel for transporting drugs into the body Micro and Nano Systems Engineering Laboratory, University of Arkansas

  4. Objectives • Measurement of cavities and fibers on micro-electrode chip • Scan the entire electrode using the AFM tool • Measure the height of the fibers, depth of the cavities and diameters of both • Match the fibers into the cavities to fabricate microelectrodes and sensors Micro and Nano Systems Engineering Laboratory, University of Arkansas
