Abstract

Nanotubes based on titanium dioxide with a high aspect ratio (>50) and a new type of crystal structure characterized by three main maxima of electron diffraction pattern at the values of diffraction vector q = 1.75 Å-1, 2.05 Å-1 and 3.35 Å-1 and two other broad peaks at q = 4.20 Å-1 and 5.25 Å-1 (diffraction vector q is defined by the equation q = 4π-sin(θ)/λ, where θ is the diffraction angle and λ is the wavelength of accelerated electrons).
