© 2019 Elsevier Ltd A detailed morphological characterisation is performed on flame synthesised TiO 2 nano-aggregates (number of primaries, N<10)using transmission electron microscopy (TEM)image analysis and mobility measurements. The size-dependent collection efficiency of the TEM sampling method is accounted for with a simple correction for particle deposition through impaction and diffusion. The TEM-derived sizes show excellent agreement with electrical mobility measurements. Primary particle size, aggregate size, and degree of aggregation distributions were obtained for two different flames and varying precursor loading rates. The analysis reveals some particle aggregation which is likely to occur only very late in the growth stage, le...
