100nm Range Short Tube Products of Nano Carbon from Solid Phase Synthesis Process Without Shortening Effort

Nguyen K.C., Tran V.V., Mai A.T.N., Bui M.C., Dang H.D., Saigon Hi Tech Park (SHTP), VN

Solid phase synthesis technique of nano carbon has reached a significant milestone in achieving short tube length in the range of 100nm. This achievement was obtained with a) specific solid carbon source (CS) having small [...]

Wafer Level Assembly of Single-Walled Carbon Nanotube (SWCNT) Arrays with Precise Positioning

Cao J., Arun A., Lister K., Acquaviva D., Bhandari J., Ionescu A.M., Ecole Polytechnique Fédérale de Lausanne, CH

A novel wafer level assembly method to fabricate SWCNT arrays with precise positioning of each individual SWCNT by ac-dielectrophoresis (DEP) is presented. Unlike the previous CNT assembly performed directly between electrode pairs, in this work, [...]

Determination of Cefixime in aqueous solution using multiwalled carbon nanotubes solid- phase extraction cartridge

Jafari M., Aghamiri F., Khaghani G.R., university of isfahan, IR

one of the most important chemical properties of carbon nanotubes is having a hydrophobic surface, and because of that many compounds and materials can be retained on the surface of these nano structures. In this [...]

Carbon Nanotubes and Grephene for Solar Cells

Li Z., Dervishi E., Saini V., Bourdo S., Biris A.S., University of Arkansas at Little Rock, US

Carbon nanotubes and graphene represent attractive materials for photovoltaic devices. Single wall carbon nanotubes (SWNTs) bear many superior properties for photovoltaic application such as a wide range of direct bandgaps matching the solar spectrum, strong [...]

Vertically Aligned Carbon Nanotube Arrays assembled on Glassy Carbon electrode

Sun J., Peking University, CN

We provide a strategy to vertically arrange single-walled carbon nanotubes on graphite electrode. The strategy is rather convenient and opens a new way to modify the graphite electrode with standing carbon nanotubes, which is criticle [...]

A Dual-Frequency Wearable MWCNT Ink-Based Spiral Microstrip Antenna

Elwi T.A., University of Arkansas at Little Rock, US

In this paper, we present a dual-frequency, square spiral microstrip patch antenna constructed from Multi-Walled Carbon Nanotubes (MWCNT) ink deposited on a thin flexible FR4 substrate using a cold printing process. The proposed antenna operates [...]

Jain D., Rouhi N., Rutherglen C., Burke P.J., University of California Irvine, US

Carbon nanotubes are currently being sought as a potential candidate in the device research area. However, a scalable manufacturing technology for nanotube devices with appropriate yield, reproducibility, and performance in various metrics (mobility, on/off ratio, [...]

Fabrication and characterization of optoelectric device using CdSe nanocrystal quantum dots/single-walled carbon nanotubes heterostructure

Shim H-C, Jeong S., Kim S., Han C-S, Korea Advanced Institue of Science and Technology (KAIST), KR

The ability to transport extracted carriers from the development of NQDs (nanocrystal quantum dots) based optoelectronic sensors have drawn considerable attention due to NQDs’ unique optical properties. Coupling of NQDs to 1-D nanostructures such as [...]

Tuning the electronic and chemical surface properties of graphane combining alkali deposition and low-energy ion irradiation

Heim B., Allain J.P., Zemlyanov D., Taylor C.N., El-Atwani O., Purdue University, US

The presence of defects in graphene due to thin-film processing can lead to alterations of its electronic properties. Tuning of graphene’s electronic properties could be achieved through control of thermal deposition of alkaline dopants (e.g. [...]
