Novel Photo-thermal Controlled Drug-releasing Vectors for Cancer Detection and Treatment

Tsai M-H, Ling D., Shieh M.J., National Taiwan University, TW

Cancer is always the leading cause of deaths in worldwide. The aim of this research is to develop a new generation of chemotherapeutic drugs with both photothermal activated drug release and MRI diagnostic function. Carbon [...]

Superhydrophobic and Superhydrophilic Nanocomposite Coatings for Preventing Microbial Adhesion on Liquid Food Contact Surface

Rungraeng N., Yoon S-H, Song W., Jun S., University of Hawaii at Manoa, US

Pathogenic microbes in biofilm matrix increase the potential of cross-contamination with processed food products, subsequently resulting in food borne disease outbreaks. Prevention of bacterial adhesion on food contact surfaces will have a massive impact in [...]

Mathematical modelling of nanoscale phenomena

Myers T.G., Font F., MacDevette M., Centre de Recerca Matematica, ES

The talk deals with 3 problems currently under investigation with the reesearch group at the Centre de Recerca Matematica: 1. Enhanced flow in carbon nanotubes. 2. Rapid melting of nanoparticles. 3. Enhanced heat transfer with [...]

Hot Phonons Contribution to scattering rates in Single-Walled Carbon Nanotubes

Gautreau P., Ragab T., Basaran C., University of Tabuk, SA

The influence of hot phonons on the electron-phonon scattering rates is studied via an Ensemble Monte Carlo(EMC) simulation with step by step update of the phonon occupation number to account for the generation of hot [...]

Experimental investigation on solidification behavior of water based CNT nanofluids for cool thermal storage system

Kumaresan V., Anna University, IN

Nano-enhanced phase change material (NEPCM) was prepared by two step method using distilled water as the base fluid, sodium dodecyl benzene sulphonate (SDBS) as a surfactant, pseudomonas as nucleating agent and multi-walled carbon nanotubes (MWCNT) [...]

The Effects of Surface Treatments on the Growth of CNTs on 3-Dimensional Carbon Foam Structure

Quinton B.T., Zhang Q., Burke J., Leedy K., Tsao B., Scofield J., Merrett J.N., Yost K., Mukhopadhyay S.M., AFRL, US

Carbon nanotubes (CNTs) have been the focus of significant research since Iijma’s 1991 Nature article. CNTs have primarily been grown on flat substrates for a range of potential applications due to their superior properties. However,limited [...]

Effect of Electron Beam Irradiation on the Tensile Properties of Carbon Nanotube Sheets and Yarns

Williams T.S., Miller S.G., Baker J.S., McCorkle L.S., Meador M.A., NASA Glenn Research Center, US

Carbon nanotube sheets and yarns were irradiated using electron beam (e-beam) energy to determine the effect of irradiation dose on the tensile properties. Results showed that there was very little change in the tensile strength [...]

Different contribution of carbon nanotubes and graphene oxide in single nucleotide polymorphism for the diagnosis of human mad-cow disease

Choi W., Lee J-H., Luminescent MD, LLC, US

Rapid single nucleotide polymorphism (SNP) with 1,1’-oxalylimidazole chemiluminescence (ODI-CL) detection was developed for the early diagnosis of human mad-cow disease. Mutated single strand DNA (ssDNA) sequence discovered from patients having human mad-cow disease rapidly hybridize [...]

Correlating electrical and structural properties in surface layer of carbon nanotube polymer composite

Pavlenko E., Tishkova V., Puech P., Bacsa W.S., CNRS and University of Toulouse, FR

We have recently shown that annealing of agglomerated carbon nanotubes on thermoplast polymers form surface composite films (70 micrometers) (1). This has been explained by preferential carbon nanotubes absorption of infrared radiation leading to local [...]

Fabrication of polymer nanocomposites based on CNTs in PDMS matrix

Imbaby M., Gottschalk K., Ulm University, DE

This research presents a new approach to fabricate polymer/carbon nanotubes (CNT) nanocomposites. Multiwall carbon nanotubes with 6-9 nm diameter and 1.5 um length is used. Polydimethysolixane (PDMS), Acetone, and Polyethylene oxide (PEO) are used as [...]
