Network Aggregation of CNT at the Surface of Epoxy/MWCNT Composite Exposed to UV Radiation

Nguyen T., Pellegrin B., Mermet L., Shapiro A., Gu X., Chin J., NIST, US

CNTs are increasingly incorporated in polymers to enhance their mechanical and other properties. However, organic polymers are prone to degrade under UV radiation. Therefore, CNTs in a polymer nanocomposite will eventually be released into the [...]

Impact of CNT Ingestion on in Vitro Cells

Mangir T., Chaves J., Chaves S., Chaves J., Chaves S., CSULB, US

In this paper we will describe our results of CNT ingestion in in vitro cell cultures. We will present AFM pictures of the observed impact of CNT on cell growth. We will describe the bio-nano [...]

In Vitro Diagnosis and Analysis of the Potential Effects of Carbon Nanotube Exposure on the Human Respiratory System

Bowen E., Purser F., Park Y.B., Lee J.S., Kwon S., Utah State University, US

Recent discoveries of various forms of carbon nanostructure have stimulated researches on their applications and hold promise for applications in medicine and many other related engineering areas. While carbon nanotubes (CNT’s) are already being produced [...]

Nanolithographic Patterning of Catalysts for Synthesis of Carbon Nanotubes

Gargate R.V., Banerjee D., Texas A&M University, US

Carbon nanotubes (CNT) were synthesized on specially custom designed MEMS chips under ambient conditions without requiring conventional Chemical vapor deposition(CVD) apparatus or process gases. In this approach, a layer of fullerene (C60) of 200 nm [...]

Studies on Carbon Nanotubes – Polyaniline Based Composites

Lal C., Kumar A., Kumar S., Kumar A., Kumar S., Gupta T.K., National Physical Laboratory (NPL), IN

ABSTRACT-: Carbon Nanotubes (CNTs) have become leading material for tremendous strategic applications. We have prepared CNT composites with the Polyaniline by solvent and powder methodology. The adhesion, alignment and the effect of composite nature have [...]

First disclosure of a viable semi-commercial single CNT-based FE device

Daren S., Kalifa I., Peretz S., El-Mul Technologies Ltd, IL

Several disclosures covering Carbon Nanotube (CNT) based devices for Field Emitter (FE) applications have been published, none of which have shown commercial viability. As a result of our research and development, El-Mul Technologies has recently [...]

Study of Dynamics of R and D of CNT in Japan Based upon Viewpoints of Nanotechnology Boom and Risk Perception

Goto A., Takenaka A., Yagishita T., University of Shizuoka, JP

The public speech of President Clinton on Jan, 2000 gave a big impact on the Japan Federation of Economic Organization because the industrial development remained sluggish in Japan. Following USA, Japanese government put a large [...]

Fabrication of Cu-encapsulated Carbon Nanotube Inductors

Lee B.C., Lee J-O, Lee B.C., Lee J-O, Choi Y.K., Yoon J.-B., Korea Institute of Science and Technology(KIST), KR

In this works, we developed a top-down fabrication method to pattern and form carbon nanotube(CNT) interconnects with Cu encapsulation. Using this method, we fabricated spiral Cu-encapsulated CNT inductors for RF ICs and investigated the inductance [...]
