Continuous Growth of Vertically Aligned Carbon Nanotubes Forests

Guzman de Villoria R., Wardle B.L., Massachusetts Institute of Technology, US

Vertically aligned carbon nanotubes are one of the most promising materials due their numerous applications in flexible electronic devices, biosensors and multifunctional aircraft materials, among others. However, the costly production of aligned carbon nanotubes, generally [...]

Carbon nanotubes transistors based Selective Gas sensors : from laboratory to mass production

Gorintin L., Thales Research and Technology, FR

Gas sensing Property of Carbon NanoTube (CNT) transistors are known for several years to be extremely sensitive to gases and thus have been proposed as gas sensors for several applications. But their versatility and their [...]

Effective carbon nanotube materials and design strategies for CNT-based electronics

Sinton S., Lockheed Martin Space Systems Company, US

Lockheed Martin and its partners are actively involved in the development of devices using carbon nanotube materials (CNTs) for various sensor and electronics applications. The challenges f acing the effective development of this technology will [...]

Highly Organized Two and Three Dimensional Singlewalled Carbon Nanotubes-Polymer Hybrid Architectures

Li B., Hahm M.G., Kim Y.L., Kar S., Jung Y.J., Northeastern University, US

We present a new class of highly organized SWCNTs network-polymer hybrid structures, by incorporating horizontally and vertically aligned SWCNTs in desired locations, orientations and dimensions on/inside flexible polymer matrices forming mechanically and electrically robust unique [...]

A Novel Approach for Modeling Mechanical Behavior of Porous Media

Altan B.S., Mollamahmutoglu M., Bayburt University, TR

A multi-scale novel homogenization technique is introduced to model mechanical behavior of open-cell porous media. The proposed method has primarily three components. The first component is based on two assumptions. First, a random porous structure [...]

Controllable growth of ZnO nanorod-carbon nanotube heterojunction arrays by low-temperature wet chemical bath deposition method for using in dye solar cell

Dehghan Nayeria F., Asl Soleimania E., Darbaria S., Sabbaghzadehb J., Mohajerzadeha S., Tehran of University, IR

In this paper, we describe a cost-effective and efficient approach for the large-scale synthesis of heterojunctions between ZnO NRs and MWCNTs. Our work represents a new type of heterostructure with many benefits. The wet chemical [...]

Scanning Probe Microscopy Study of M13 on Graphite

Steinsultz N., Sharma P., Suffolk University, US

In this work, we use a combination of atomic force microscope (AFM) and scanning tunneling microscope (STM) to study the structure and binding of wild-type M13 bacteriophage adsorbed on freshly cleaved graphite in ambient condition. [...]

Physical stability of nanoparticle dispersion

Fleury M., Lefeuvre Y., Tisserand C., Brunel L., Meunier G., Formulaction, FR

Nanoparticles applications in the industry are getting more and more important and concern many different fields (drug delivery, carbon nanotubes, display technologies, etc.). In the last decades a vast amount of scientific research has been [...]

Electromagnetic wave shielding effectiveness of SWNT-coated, transparent, conducting panels

Nam I.W., Lee H.K., Sim J.B., Choi S.M., KAIST, KR

Needs for electromagnetic wave shielding/absorbing have been increased in order to prevent electromagnetic interference, eavesdropping, and harmful effects to human bodies (Chung, 2001; Kim and Lee, 2008). Single-walled carbon nanotubes (SWNTs) have been well-known for [...]

Synthesis and characterization of La0.75Sr0.25Cr0.5Mn0.5O3- nanoparticles using combustion method

Reddy Channu V.S., Holze R., Walker Jr. E.H., Kalluru R.R., Technische universtat of Chemnitz, DE

La0.75Sr0.25Cr0.5Mn0.5O3-δ (LSCM) perovskite phase nanoparticles were successfully synthesized by solution combustion method using different carriers (NTP, oxalic acid, and citric acid) after calcination of fired gel at 1200 ºC for 7h. Scanning electron microscopy (SEM) [...]
