Project #6 Surface Modification of Carbon Nanotubes for Property Improvement Cuong Diep – pre-junior, Chemical Engineering Milena Fernandez – pre-junior, Computer Engineering College of Engineering and Applied Science; University of Cincinnati; Cincinnati, Ohio Dr. Vesselin Shanov- Chemical and Materials Engineering, CEAS Dr. Noe Alvarez- Chemical and Materials Engineering, CEAS Sponsored ByThe National Science Foundation Grant ID No.: DUE

Goals To design a transformer using CNT threads 2 Objectives 1.Design transformer 2.Modify CNT threads by the processes of doping and coating. 3.Replace Cu wires by CNT threads 4.Using a battery, light up LEDs CNT- Carbon nanotubes Cu- Copper LED- light-emitting diode, used as a light source Transformer- electrical device

Final Product 3 Source: Energy Efficiency Battery connected to primary coil LED connected to secondary coil CNT threads will replace coils Transformer

Tasks Learn how a transformer works Understand properties of CNTs Learn process of doping and coating CNT threads Choose ideal transformer design Wrap CNT threads on transformer Connect battery and LED to CNT threads Light up LED! 4

Materials Carbon Nanotube threads Nitric Acid Sulfuric Acid. 5
