Synthesis of Single Walled Carbon Nanotubes Using Cobalt Grafted in MCM-41 as Catalyst

Giraldo L.F., López B.L., Haller G.L., Universidad de Antioquia, CO

In this work (SWCNTs) have been synthesized by high pressure CO decomposition using cobalt grafted in MCM41 by means of grafting method employing cobalt (II) acetylacetonate. The reduction temperature of the metal species of this [...]

Design and Fabrication of Electromechanical Tweezers based on CNT Ropes

RAslan A., Basrour S., Le Poche H., CEA-LETI,Minatec, FR

The aim of this work is to design and fabricate electromechanical tweezers based on CNT ropes. The electromechanical behaviour of such ropes has been studied. The average of Young’s modulus of the rope has been [...]

Transparent film sensor for strain measurement using carbon nanotube networks

Chang W.-S., Song S.-A., Kim J.H., Kim J.W., Kim J.H., Kim J.W., Lee H-C, Han C-S, Korea Institute of Machinery and Materials, KR

Since the carbon nanotube was reported by Iiijima, it has been intensively studied due to their great potential in nanoelectronics and nanomechanical devices. Recently, experimental results show that sing-wall carbon nanotubes (SWCNTs) change their electronic [...]

Controlled growth and electrical characterization of bent single-walled carbon nanotubes

Huang J., Choi W.B., Florida International University, US

The unique electrical and mechanical properties of single-walled carbon nanotubes (SWNTs) make them one of the most promising candidates for next generation nanoelectronics. However, synthesis of complex geometries for as-grown SWNTs still remains a challenging [...]

Chirality Separation of single walled carbon nanotube using microfluidic

Han C-S, Shin D-H, Kim J-E, Shim H-C, Kang J-M, Baek S-H, Korea Insitute of Machinery & Materials, KR

Carbon nanotubes were separated by dielectrophoresis in a micro-fluidics chip, which is easy to scale-up the process. We used the H-filter with micro size channels, which have two inlets and two outlets. In this experiment, [...]

Separation Mechanisms for Nanoscale Spheres and Rods in Field-Flow Fractionation (FFF)

Phelan Jr. F.R., Bauer B.J., NIST, US

A Brownian dynamics simulation for modeling the separation of spheres and rodlike particles in field-flow fractionation (FFF) is developed. Modeling of particle elution for spheres from (10 to 1000) nm was examined. The simulation captures [...]

Multi-Functional Carbon Nanotube Based Filtration Material

Cummings A., Seldon Technologies, Inc., US

The very small diameters of carbon nanotubes (CNTs) present relatively low resistance to fluid flow. This, combined with their high surface area, means that highly-efficient, bio-contaminant removals are possible with a thin filtration media possessing [...]

Characterization of Activated Carbon particles for nanocomposite synthesis

Terrazas-Bandala L.P., Zaragoza-Contreras E.A., González-Sánchez G., Ballinas-Casarrubias M.L., Advanced Materials Research Center (CIMAV), MX

Activated carbon from inexpensive sources has been of great interest for separation systems, efforts had been made to produce AC nanoparticles by different means, in the aim to integrate them to composite materials to enhance [...]

Growth and characterization of CNT Forests using Bimetallic Nanoparticles as Catalyst

Lee B.J., Lee G.S., Lee K.H., Sra A.K., Jang H.-S., Lee B.J., Lee G.S., Lee K.H., Overzeta L., Yang D.J., Lee B.J., Lee G.S., Lee K.H., The University of Texas at Dallas, US

In this poster, we will discuss about a simple efficient way of producing bimetallic FePt, FeCo alloy nanoparticles that are used as catalysts for continuous growth of forests of MWCNTs by PECVD or thermal CVD [...]
