New Nano Solid Based on Carbon Nanomaterials-Nanoparticle through Aqueous Solutions

Hong H., Younes H., Grablander T., Bailey C., Novum Nano, US

A better understanding of the bonding and aggregation processes occurring between carbon nanomaterials and metal oxide particles in aqueous solutions is important in developing novel nanosolids for applications in sensor development, highly conductive paint nanotube [...]

Fabrication and Design of Carbon Nanomaterials Based Scale Monitoring Smart Sensor Systems

Younes H., Jelbuldina M., Sofela S.O., Tizan L., Al Ghaferi A., Saadat I., Masdar, AE

Scale is the creation of inorganic soluble salts from aqueous brines during oil and gas production. The scale deposits at the internal surface of the pipelines under the supersaturation conditions. The deposition of the scale [...]

ROS Evaluation for Series of CNTs Using the ESR Method and the Effects of CNT Mophology

Tsuruoka S., Takeuchi K., Koyama K., Endo M., Fujisawa K., Matsumoto H., Saito N., Usui Y., Porter D.W., Castranova V., Shinshu University, JP

Carbon nanotubes (CNTs) are becoming important materials in industry. It is a concern that CNTs may induce carcinogenic responses through pulmonary exposure. It has been recently reported1-6 that CNTs scavenge ROS depending on their morphology. [...]

Growth of Uniform CNT Layer on Copper Foil-the Effect of Synthesis Methods/Conditions

Zhang Q., Scofield J., Tsao B., Merrett J.N., Quinton B.T., Burke J., Pierce N., University of Dayton, US

Carbon nanotubes (CNTs) with unique thermal/electrical/mechanical properties and large surface area are an attractive candidate for the integration into thermal structures and for a flexible thermal interface material in a thermal device. In this study, [...]

Controllable Sequential Low Temperature Plasma Assisted Growth of Vertical Multi-wall & Single-wall CNTs

Kolahdouz Z., Darbari S., Mohajerzadeh S., University of Tehran, IR

By investigating the effects of growth parameters of CNTs, we have arrived at small diameter, single/multi-wall nanotubes at low temperatures. Synthesis of CNTs was performed using the gas mixture of the C2H2/CH4 gas and H2 [...]

Carbon-based Nanoelectronic Devices for Space Applicatoins

Kaul A.B., Khan A.R., Megerian K.G., von Allmen P., Bagge L., Epp L., Baron R.L., Jet Propulsion Laboratory, US

The microelectronics industry based on Silicon (Si) continues to push the limits on scaling, which has created unique opportunities for nanoscale materials, such as carbon nanotubes (CNTs) and carbon nanofibers (CNFs). We will describe our [...]

Enhanced Field Emission properties of Titanium decorated Multiwalled Carbon Nanotubes

Sharma H., Kaushik V., Shukla A.K., Vankar V.D., Indian Institute of Technology Delhi, IN

we report the role of Ti on the growth and field emission properties of multiwalled carbon nanotubes (MWCNTs), prepared by microwave plasma enhanced chemical vapour deposition technique (MPECVD). First set of studies were carried out [...]

Flame synthesis of carbon nanotubes using a double-faced wall stagnation flow burner

Woo S.K., Hong Y-T, Kwon O.C., Sungkyunkwan University, KR

The potential of using a double-faced wall stagnation flow burner in mass production of carbon nanotubes was evaluated experimentally and computationally. With nitrogen-diluted premixed ethylene-air flames established on the Ni-coated stainless steel or Ni-sintered, double-faced [...]

Safety, Health, and Environmental Awareness in Nanotechnology Training

Iyuke S.E., University of the Witwastersrand, ZA

The statistical evaluation of the SHE survey strongly supports nine out of the twenty nine test statements to be addressed by practicing nanotechnologists with regards to safety, health and the environment, which are: (1)Sizes, aspect [...]
