Breakage of TiO2 agglomerates in electrostatically stabilized aqueous dispersions
TL;DR: In this article, the mean diameter of sonicated titania nanopowders was correlated inversely to the specific energy, and both erosion and fracture mechanisms were observed, however, none of the commercial nanopowsders were successfully broken to their primary particle sizes and reagglomeration of the dispersion could be prevented by electrostatic stabilization with nitric acid or ammonium hydroxide.

Ultrasonic Dispersion of TiO2 Nanoparticles in Aqueous Suspension
TL;DR: In this paper, the aggregation and dispersion behavior of nanometer and submicrometer scale TiO2 particles in aqueous suspension were investigated using three kinds of mechanical dispersion methods: ultrasonic irradiation, milling with 5-mm-diameter balls, and milling using 50 μm beads.

Self-preserving size spectra of comminuted particles
TL;DR: In this paper, three pertinent aspects associated with grinding of brittle solids, namely, grinding kinetics, particle-size distributions and energy-size reduction relationships have been unified in the framework of a phenomenological model of particle size reduction.
