A work focused on nanostructured titanium dioxide (TiO2) has been published on Nature Nanotechnology on April 2010.
The combination of electron diffractive imaging and high-resolution transmission electron microscopy (HRTEM) can image individual TiO2 nanocrystals with a resolution of 70 pm. HRTEM measurements were performed at the TASC Laboratory.
The figure on the left shows a false-coloured experimental phase-contrast HRTEM image of an individual TiO2. On the right an enlargement of a portion of the TiO2 nanocrystal (top) and a phase-retrieved diffractive image (down) are shown.
