Pt-Ru nanoparticles Supported on MWCNT as PEM fuel cell Electrocatalysts

Valenzuela-Muñiz A.M., Miki-Yoshida M., Botte G.G., Verde Y., Centro de Investigación en Materiales Avanzados S.C., MX

Support plays an important role in catalyst activity. Small particle size in catalysts provides a high contact area between active phase and the reagents, having as consequence a better activity. Multi Wall Carbon Nanotubes (MWCNT) [...]

Adsorption of Pb2+ using platinum and ruthenium on carbon nanotubes

Azpeitia J.A., Zepeda A., Torres L., Verde Y., Instituto Tecnologico de Cancun, MX

Recently, remove Pb2+ ions from drinking water has been focused due to its high toxicity to our health, such as nausea, convulsions, coma, renal failure, cancer and subtle effects on metabolism and intelligence. Different approaches [...]

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, [...]
