From Electrical to Fuel Powered Artificial Muscles

Kozlov M.E., Oh J., Mirfakhrai T., Zhang M., Fang S., Ferraris J.P., Madden J.D.W., Baughman R.H., University of Texas at Dallas, US

A number of materials ranging from carbon nanotube yarns and sheets to shape memory alloys (SMA) have been explored for the application in the area of artificial muscles (actuators). It was found that if powered [...]

Preparation and Electrochemical Characterization of Porous SWNT-PPy Nanocomposite Sheets for Supercapacitor Applications

Oh J., Kozlov M.E., Baughman R.H., University of Texas at Dallas, US

Highly porous sheets comprised of Single Walled Carbon Nanotubes and doped polypyrrole (SWNT-PPy) were prepared by vacuum filtration of SWNT-PPy methanol dispersions. The employed preparation procedure is an extension of conventional bucky-paper fabrication method for [...]

Numerical Analysis of the Effect of Diffusion and Creep Flow on Cavity Growth at the Nano-scale Level

Brust F.W., Oh J., Battelle Memorial Institute, US

At high temperature, cavity initiation and cavity growth are important phenomena in understanding the failure mechanism and in predicting the lifetime of various parts in service in the area of power plants, aerospace applications, among [...]

A Study on the Novel Type of Ferrofluid Magnetic Pipette

Ahn J.J., Oh J., Choi B., Sogang University, KR

This study was performed to design the novel type of ferrofluid magnetic pipette on a micro scale for the purpose of applications to delivery systems, which is the core device of Lab on a chip [...]
