Environmental and Economic Assessment of Nano-Fabrication Processes of Memory Devices

Dahlben L., Isaacs J.A., Northeastern University, US

The unique mechanical, electronic, and non-volatility of carbon nanotubes (CNT) have significant potential to replace current silicon-based switches. However, before fully integrating CNT switches into the semiconductor industry, the production costs and environmental impacts associated [...]

Multi- Walled Carbon Nanotubes Increase the Efficiency of Hyperthermic Chemotherapy

Levi-Polyachenko N.H., Merkel E., Jones B.T., Wagner W.D., Carroll D.L., Stewart IV J.H., Wake Forest University Health Sciences, US

A clinically applied method to enhance drug localization for abdominal malignancies of colorectal cancer involves a two-hour perfusion of hyperthermic (40-42ºC) chemotherapeutic agents; however, all cavity tissues are subjected to enhanced drug delivery due to [...]

Multiwalled Carbon Nanotube-Doxorubicin Supramolecular Complexes for Cancer Therapeutics

Ali-Boucetta H., Al-Jamal K.T., Kostarelos K., The School of Pharmacy, University of London, UK

The field of drug delivery is being revolutionised by the discovery of novel nanomaterials such as carbon nanotubes (CNTs) capable of traversing the plasma membrane and promoting the cellular uptake of small molecules and macromolecules [...]

Precision Placement and Integration of Individual Carbon Nanotubes in Nanodevices by Fountain-Pen controlled Dielectrophoresis

Schwamb T., Schirmer N., Poulikakos D., ETH Zürich, CH

Herein, we present a novel fabrication method for the integration of special nanoparticles such as nanowires and carbon nanotubes into NEMS/MEMS. To this end, we combined the dielectrophoretic deposition of carbon nanotubes with a fountain-pen [...]

Preparation of transparent electrodes based on CNT-s doped metal oxides

Paalo M., Tätte T., Visk U., Lõhmus A., Lõhmus R., Lõhmus A., Lõhmus R., Kink I., University of Tartu, EE

High Strength Metal-Carbon Nanotube Composites

Goyal A., Wiegand D.A., Owens F.J., Iqbal Z., New Jersey Institute of Technology, US

Carbon nanotubes have been extensively investigated for developing polymer matrix nanocomposites and a number of such nanocomposites are already being used in various applications [1, 2]. Metallic composites, particularly those of aluminum, containing carbon nanotubes [...]

Development of nanocomposites with carbon nanotubes in a thermoplastic elastomer matrix

Broza G., Roslaniec Z., Schulte K., Technische Universitaet Hamburg, TUHH, DE

Thermoplastic elastomers (TPEs) have the potential for application as engineering materials because of their novel properties and ease of processing. We have developed a polycondensation process, which allows the manufacturing of polybutylene terephthalate/polyoxytetramethylene (PBT/PTMO) block [...]
