Tuning the Gas Pressure Discharge of Nanoenergetic materials by Boron and Carbon Nanotube Additives

Martirosyan K.S., Wang L., Luss D., University of Texas at Brownsville, US

Thermite reactions are highly exothermic and may rapidly release high amount of stored chemical energy in the form of heat, light and wave. Nanothermite formulations that use aluminum or magnesium as the reducing agent and [...]

Fabrication and characterization of thin-film transistors based on printable functionalized single-walled carbon nanotubes

Zhao J., Lin J., Cui Z., Suzhou Institute of Nano-tech and Nano-bionics (SINANO), CAS, CN

In this study, we reported a simple functionalization approach to preparing high-quality SWNT ink. We demonstrated that metallic species and small diameter semiconducting species in CoMoCat 76 could be effectively eliminated after reaction with 2, [...]

Increased Sensitivity of Carbon Nanotube Sensors by Forming Stable and Low Resistance CNT/metal Electrode

Jeon D., Park D., Lee S., Seoul National University, KR

We fabricated a rigid and low resistance contact for CNT by utilizing a eutectic mixture melting at low temperature as an electrode. The fabrication was done by depositing a eutectic Au/Al thin film on the [...]

Carbon Nanotube Arrays with Tunable Wettability and Their Applications

Indrat Aria A., California Institute of Technology, US

A combination of UV/ozone treatment and vacuum-pyrolysis process that can be used for fine tuning the wetting properties of the CNTs is introduced. In contrast to the widely known wet-chemical methods the UV/ozone treatment is [...]

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 [...]

A Molecular Dynamics Modeling on Cantilevered Triple-Walled Carbon Nanotube Resonators

Lee J-H., Kwon O-K., Kang J-W, Hwang H-J., Sangmyung University, KR

We introduce intertube interactions of cantilevered (3,3)(8,8)(13,13) triple-walled carbon nanotube resonators via classical molecular dynamics simulations. The fundamental frequencies of TWCNT resonators were less than those of single- and double-walled carbon nanotubes of a given [...]

Novel first-principle simulations of 3D atomistic structure

Zhang D., Polizzi E., UMass, US

Modeling approaches in computational electronics have become increasingly driven by the need of more fundamental and comprehensive understanding of the nanoscale physics of system only through knowledge of the constituent atoms. First principle calculation, which [...]

Novel metal nanoslit by dewetting of thermally activated Au film on CNT

Im H., Seoul National University, KR

It has been studied by many research groups to fabricate nano-sized hole or slit array of metal film. By using various fabrication methods, such as photolithography, and nano-imprint, have been studied. However, there still remain [...]

Functionalization of Carbon Nanotubes for Advanced CNT/LCP Nanocomposites

Sahoo N.G., Cheng H.K.F., Li L., Chan S.H., Zhao J., Nanyang Technological University, SG

A novel approach has been made to the chemical functionalization of multi-walled carbon nanotubes (MWCNTs) for developing advanced polymeric nanocomposites with liquid crystalline polymer (LCP). In the approach, we have selectively introduced two types of [...]

Carbon Nanotube Field Effect Transistors using Printed Semiconducting Tubes

Rouhi N., Jain D., Zand K., Burke P.J., Univ. of California-Irvine, US

Purified, all-semiconducting nanotubes offer great promise for a variety of applications in RF and microwave electronics. It has been showed theoretically that carbon nanotube electronic devices have the potential of going into THz regime since [...]
