Cutting Fluorinated/Ozonated Single-Walled Carbon Nanotubes by Pyrolysis

Chen Z., Gu Z., Ziegler K., Chan C.K., Shaver J., Hauge R.H., Smalley R.E., Rice University, US

Fluorinated/ozonated Single-Walled Carbon Nanotubes (SWNTs) was found to have been cut to short length by Pyrolysis and/or piranha treatment. Large scale cutting of SWNTs would lead to novel applications of nanotubes in microelectronics, biological imaging [...]

Improvements in High Specific Strength Epoxy-Based Composites using High Magnetic Fields

Mahfuz H., Zainuddin S., Rangari V.K., Jeelani S., Tuskegee University, US

Numerous studies have been carried out, over a period of several years, on the detection of changes in physical characteristics of polymers subjected to high magnetic fields during the curing stages. Extremely large increases in [...]

Platinum Nanowire Actuator: Metallic Artificial Muscles

Lu S., Sivakumar K., Panchapakesan B., University of Delaware, US

In this paper, we have fabricated platinum nanowires by using carbon nanotube as templates and have shown its applications for nanoactuation using electro-chemical actuation techniques.The strain response of the nanowire is measured and a total [...]

Structure and Rheology of Supercritical Carbon Dioxide Exfoliated Polymer Nanocomposites

Serhatkulu G.K., Horsch S.E., Kannan R., Gulari E., Wayne State University, US

A major technological barrier to achieving superior properties of nano-structured composite materials is the difficulty of dispersing fillers uniformly in a host matrix. The existing nanocomposite manufacturing processes achieve property improvements through chemical modifications of [...]

Development of a Biologically Enhanced Carbon Nanotube Based Composite

Parker R., O’Neal R., Fisher D., Davey Kirk, Liang R., Edwards J., Florida A&M University, US

Composite materials continue to be important to the evolution of human space flight activity. The low weight/high strength ratio and thermal properties of carbon based composite materials in particular that make them well suited for [...]

Nano-Reinforcement of Epoxy Adhesives with POSS

Chian W., Mallampalli C., Winter R.M., South Dakota School of Mines & Technology, US

ABSTRACT The reinforcement of epoxy adhesive with polyhedral-Oligomeric-SilSesquioxane (POSS) was studied. Shear performance of the nano-filled adhesive was evaluated as a function of filler content using the single-strap bonded joint configuration. It is found that [...]
