In the case of titania beads, grain diameter size was adjusted by changing the amount of precursor (titanium (IV) isopropoxide, TIP), hexadecylamine (HDA) or Potassium Chloride (KCl) and reaction temperature as well as the rotation speed of the cylinder.

A new nondestructive test method of three-step phase-shifting correlation speckle pattern interferometry to study the dynamic loads of structural materials is proposed. In this method three speckle interferograms (SIs) of the specimen surface, differing only by arbitrary unknown phase shifts, are recorded before the loading and one SI is recorded under the dynamic load. The surface displacement field under dynamic loading is determined using the obtained SIs. Two algorithms for the implementation of the method are proposed.
