  • Carbon nanotube surface science

    This paper presents a surface science perspective on sidewall functionalisation of carbon nanotubes. Carbon nanotubes are varyingly described by physicists as extended solids or by organic chemists as molecules. As prototypical nanostructures, they are indeed a little bit of both. Their chemistry and resulting potential applications can only truly be appreciated by combining both perspectives. ...

  • Influence of carbon nanotubes on the bioavailability of fluoranthene

    Concurrent with the increase in the use of carbon nanotubes (CNTs) in society is the increase in their introduction into the environment. CNTs cause adverse effects themselves and they have the potential to adsorb contaminants such as polycyclic aromatic hydrocarbons (PAHs). Though CNTs have a high adsorption capacity for PAHs and these contaminants can co‐occur in the environment, few studies ...

  • Quantum confinement in carbon-nanotube systems

    Carbon nanotubes are graphene cylinders of nanometric diameter which can be either semiconducting or metallic depending on their geometry. Joining different kinds of nanotubes by means of topological defects, one can design all-carbon quantum dots and, in principle, achieve electronic confinement in quasi-zero dimensional systems. In this work, we review different ways of quantum electron ...

  • Longitudinally unzipped carbon nanotubes for supercapacitors

    In this study, longitudinally unzipped carbon nanotubes (L–UCNTs) prepared from multiwalled carbon nanotubes and their electrochemical properties for supercapacitors were investigated after thermal treatment. Thermally treated L–UCNTs (RL–UCNTs) had a specific surface area of 288 m²/g and mesoporous pore characteristics. Also, RL–UCNTs had numerous oxygen heteroatoms, which affected ...

  • Nanomanufacturing of carbon nanotubes on titanium nitride

    Carbon nanotubes (CNTs), in particular the vertically-aligned variety grown through a PECVD-based process, are highly versatile nanostructures that can be used in a variety of nanomanufacturing applications. However, process and material compatibility issues have prevented the nanotubes from becoming more fully integrated into various micro- and nanomanufacturing applications. In this paper, we ...

  • Functionalised carbon nanotubes: high biocompatibility with lack of toxicity

    Recent studies from our laboratories have clearly shown the utility of the carbon nanotubes (CNTs) in biomedical applications. Therefore, the behaviour of CNTs following in vivo administration is of high interest. In this paper, we summarise some of our previously published results towards the assessment of the health impact of CNTs. We will initially describe the in vivo distribution of ...

  • Fabrication and characterisation of suspended carbon nanotube devices in liquid

    Suspended carbon nanotube devices represent a promising platform for future bio-electronic applications. Suspended carbon nanotube transistors have been previously fabricated in air; however all previous attempts to bring them into liquid failed. We analyse forces acting on the suspended nanotube devices during immersion into liquids and during device operation and show that surface tension ...

  • Carbon nanotubes: from production to functional composites

    In this paper, we present our work on carbon nanotubes, including our most recent results, in two important fields: production of carbon nanotubes itself and fabrication of carbon nanotube based composites with enhanced functionality. Firstly, we focus on the three main carbon nanotube production techniques, namely electric arc, laser evaporation and CVD. Based on our results, for each method the ...

  • On the possible optical resonance in carbon nanotubes based cavities

    An enhanced interference phenomenon in the IR absorbance-wavenumber profiles of ship-shaped carbon nanotubes powder has been observed by attenuated total reflection at room temperature. This room temperature interference phenomenon was considered as possibly originating from an optical resonance effect and that single carbon nanotubes could act as individual Fabry-Perot or Lummer-Gehrcke resonant ...

  • Toxicity of carbon nanotubes to freshwater aquatic invertebrates

    Carbon nanotubes (CNTs) are hydrophobic in nature and thus tend to accumulate in sediments if released into aquatic environments. As part of our overall effort to examine the toxicity of carbon‐based nanomaterials to sediment‐dwelling invertebrates, we have evaluated the toxicity of different types of CNTs in 14‐d water‐only exposures to amphipods (Hyalella azteca), midges (Chironomus dilutus), ...

  • Mineralization of phenanthrene sorbed on multiwalled carbon nanotubes

    Carbon nanotubes have attracted attention around the world because of their high sorption capacity for hydrophobic organic compounds (HOCs); however, the bioavailability of HOCs sorbed on carbon nanotubes to bacteria is not well known. In the present study, 14C‐labeled and unlabeled phenanthrene was spiked onto four kinds of multiwalled carbon nanotubes (MWCNTs) and aged for 60 d, and the ...

  • Stable dispersions of single-walled carbon nanotubes

    The degree of dispersion of Single-Walled Carbon Nanotubes (SWCNTs) in different solvents is an issue in all studies where applications (in microelectronics, as well as in biological in vitro and in vivo systems) are envisaged. We performed long-term dispersion studies of SWCNTs in four different solvents: phosphate buffer solution (PBS), poly(sodium 4-styrene-sulfonate) (NaPSS), Gum Arabic (GA), ...

  • Selective detection and quantification of carbon nanotubes in soil

    Carbon nanotubes (CNTs) have been widely applied in many fields of industry. As the world production of CNTs is increased, the risk of the exposure of the environment to CNTs is also increased. Therefore, in order to evaluate the impact on the environment, many cell or animal toxicity experiments have been reported using CNTs. It is important to determine the degree of contamination of CNTs in ...
