Novel supported catalytic materials based on multiwalls carbon nanotubes

Koltypin Y., Savilov S.V., Gedanken A., Landau M.V., Bar-Ilan University, IL

We present a method that allows proper control of the nanoscale curvature of the external surface in multiwall carbon nanotubes (MWCNT) and shown its effect on the properties of Ni/MWCNT catalyst. After removal of residual [...]

Carbon-supported platinum and nickel nanoparticles for CO capture in hydrogen fuel cells

J. D. Durbin D., J. Fermin D., Plana D., J. D. Durbin D., J. Fermin D., Malardier-Jugroot C., Royal Military College of Canada, CA

Fuel cells are electrochemical cells that convert chemical energy into electrical energy with efficiencies up to 80%; they are a promising potential replacement for internal combustion engines in automobiles. However, carbon monoxide poisoning of the [...]

Properties of Linear Low Density Polyethylene Reinforced with Multi-walled Carbon Nanotubes by Cryogenic Ball-Milling

Narh K.A., Terife G., New Jersey Institute of Technology, US

The combination of high aspect ratio, small size, very low density, and more importantly, excellent physical properties, such as extremely high mechanical strength and stiffness, high electrical and thermal conductivity, make carbon nanotubes (CNTs) perfect [...]

Managing Your Environmental, Health & Safety Risk: A Guide for Nano Companies and their Insurers

Sarahan P.C., Bushong H., Fulbright & Jaworski L.L.P., US

Nanotechnology companies are facing increasing scrutiny as federal and state agencies adopt regulations and propose recommended workplace practices and exposure standards. In addition, more studies are being released that indicate that some nanomaterials present the [...]

Enhanced Cell Electro-permeabilisation Combined with Phototherapy to Target-Killing Cancer Cells by Using Multi Functional Carbon Nanotubes

Lee P-C, National Taiwan University, TW

Carbon nanotubes (CNTs) have been proposed and actively explored as multifunctional innovative carriers for drug delivery. This project presents a new modality for cell electro-permeabilisation based on the use of CNTs and external static electric [...]

Titanium Tungsten Coatings for Bioelectrochemical Applications

Wierzbicki R., Amato L., Lopacinska J., Heiskanen A., Emneus J., Boggild P., Molhave K., DTU Nanotech, DK

Our research interest is the combination of carbon nanotube electrochemistry with nanostructured substrates capable of cell scaffolding. Therefore, an adhesion / electric connection coating with good biocompatibility, PECVD compatibility and electrochemical stability needs to be [...]

Lumped Modeling of Carbon Nanotubes for M/NEMS Simulation

Bansal R., Clark J.V., Purdue University, US

The construction and analysis of the CNT structure is extremely difficult and requires expertise in nanostructure physics. This limits access to molecular dynamics specialists and does not allow the exploration of CNTs as components of [...]

Simulating the Fast Transport of Water Through Carbon Nanotubes

Nicholls W.D., Borg M.K., Reese J.M., University of Strathclyde, UK

This paper presents our simulation results of pressure-driven water flow through a single (7,7) CNT 2.5nm in length as part of an investigation of the reasons for such high flow rates. A pressure gradient is [...]

Parallel Fabrication of Single-Walled Carbon Nanotube based Piezoresistive Pressure Sensors

Burg B.R., Helbling T., Hierold C., Poulikakos D., ETH Zürich, CH

A major obstacle in the realization of commercially viable single-walled carbon nanotube (SWNT) based devices, hindering the functionality of this uniquely interesting type of material, is their type and site selective integration. In this work, [...]
