Direct observation of excitons in polymer/carbon nanotube composites at room temperature: The influence of nanotube concentration
(2008)In this work, we have employed spectroscopic ellipsometry technique to study the optical properties of polymer/carbon nanotube (CN) composites as a function of nanotube concentration. Using a two-layer structural model ...

Formation mechanism of nanotubes comprising layers of PbS nanoparticles in polymer-surfactant solutions
(2006)The crystallization of PbS in aqueous solutions containing the surfactant sodium dodecyl sulfate (SDS) and hydrophilic polymers resulted in a novel type of metastable nanotubes, the walls of which consist of layers of ...

Molecular dynamic simulations of carbon nanotubes in CO2 atmosphere
(2008)This work investigates by means of molecular dynamics the filling of carbon nanotubes by carbon dioxide molecules. Nanotubes of various sizes are simulated and the resulting CO2 density calculated. The effects of various ...

Self-diffusivity, hydrogen bonding and density of different water models in carbon nanotubes
(2008)In this paper, the density, hydrogen bonding and self-diffusivity of water confined in carbon nanotubes are investigated. Molecular dynamics is used to simulate a large variety of nanotubes with various water models. Our ...
