    Carbon nanotube - Wikipedia

    Structure of single-walled tubes . The structure of an ideal (infinitely long) single-walled carbon nanotube is that of a regular hexagonal lattice drawn on an infinite cylindrical surface, whose vertices are the positions of the carbon atoms. Since the length of the carbon-carbon bonds is fairly fixed, there are constraints on the diameter of the cylinder and the arrangement of the atoms on it.

    However, no devastating damage and fracture happened on MWNTs after acid treatment under mild conditions. Precipitation observation illustrated that the enhanced solubility of MWNTs in water, ethanol, and dimethylformaide (DMF). Further, MWNTs/polyetherimide (PEI) nanocomposite films have been prepared by the simple solution casting method.

    Electrical breakdown of short multiwalled carbon nanotubes

    Abstract Electrical breakdown of short (˜50nm) multiwalled carbon nanotubes (MWNTs) is studied utilizing mechanically controllable break junction technique with gold electrodes. Measurements of the conductance-bias characteristics near the breakdown point revealed two different types of breakdown behavior for the short MWNTs.

    Abstract Luminescence of the short multiwalled carbon nanotubes (MWNTs) conjugated with carboxylic acid groups has been studied. The results show that the carboxyl-functionalized short MWNTs could emit luminescence and the emission peak appears at 500 nm with a corresponding optimal excitation wavelength centering at 310 nm.

    a lot of short MWNTs were found close to the surface of the support, which is more clearly shown in Figure 1f. Since we cannot find such tubular carbonaceous impurities in Figure 1c, which shows the surface of the raw materials from Co/MgO catalysts, it was highly possible that such short MWNTs resulted from the Mo addition.
