Controlled Assembly of Highly Density SWNT Networks on a Flexible Parylene-C Substrate

Chen C.-L., Xiong X., Busnaina A., Dokmeci M.R., Northeastern University, US

Single-walled carbon nanotubes (SWNTs) with their attractive properties such as large surface-to-volume ratio, high packing density and long-range order may serve as the potential building blocks for the next generation of nanoscale devices. The integration [...]

Diameter Selective Growth of Vertically Aligned Single Walled Carbon Nanotubes by Ethanol Flow Control

Hahm M.G., Noah M.A., Kwon Y., Jung Y.J., Northeastern University, US

The role of ethanol flow rate in CVD process for the diameter control of vertically aligned-SWNTs is presented. Three different flow rates of ethanol (50, 100, and 200 sccm) were supplied to grow VA-SWNTs while [...]

Investigating the Benefit-Cost of MEMS Application for Structural Health Monitoring of Transportation Infrastructure

Jha M.K., Davy A.B., Morgan State University, US

This paper develops a fuzzy-logic based procedure for quantitative cost and benefit calculation of MEMS application for structural health monitoring of transportation infrastructure. This will be a major step forward for widespread MEMS application in [...]

Molecular Simulation Studies on Adsorption of Mercuric Chloride

Kotdawala R.R., Kazantzis N., Thompson R.W., Worcester Polytechnic Institute, US

The need to develop technologies capable of achieving high removal efficiencies for mercury chloride emission control led many researchers to focus their attention on the evaluation of the adsorption capacity and selectivity shown by different [...]

Dynamics of Water in Nafion Fuel Cell Membranes: the Effects of

Moilanen D.E., Piletic I.R., Fayer M.D., Stanford University, US

The complex environment experienced by water molecules in the hydrophilic channels of Nafion membranes is studied by ultrafast infrared pump-probe spectroscopy. A wavelength dependent study of the vibrational lifetime of the O-D stretch of dilute [...]

Molecular Building Blocks for Efficient Solid State Lighting

Burrows P.E., Sapochak L.S., Pacific Northwest National laboratory, US

General illumination consumes 22% of the electricity generated in the U.S. This huge proportion is partly due to the ubiquity of artificial lighting but also the inefficiency of converting electrical energy to light. Incandescent lightbulbs [...]

Biosensor for heavy metals using hydrothermally grown ZnO nanorod/nanotube and metal-binding peptides

Jia W., Reitz E.T., Lei Y., University of Connecticut, US

Certain heavy metals can pose potential health risks when consumed by humans due to their high toxicity. Specifically, the heavy metals mercury, lead and cadmium can be released into the environment through industrial use and [...]

Bulk Heterojunction Organic-Inorganic Photovoltaic Cell Based on Doped Silicon Nanowires

Goncher G., Noice L., Solanki R., Portland State University, US

A bulk heterojunction organic-inorganic photovoltaic cell was fabricated by growing doped n-type silicon nanowires on an n+ silicon substrate. A p-type organic semiconductor (P3HT) was then coated over the nanowires. The device was completed by [...]

Systematic Approach on Modeling and Identification for Nanobattery Prototyping
