a STEM-HAADF (Z-contrast) image of randomly oriented titanium oxide nanocondensates in sample 2, b and c EDX scanning profile of lines 1 and 2 showing varied counts of Ti and O, dg point count analysis at point dg as labeled in the image for titanium oxide nanoparticles with decreasing O/Ti ratio. The Cu and C peaks are from supporting copper grids overlaid with a carbon-coated collodion film
