A spray sonocrystallization (SSC) method is described here for the crystallization of pharmaceutical agents that provides for a tunable crystal size and narrow size distribution in the submicron regime. SSC uses a tapped, flow-through ultrasonic horn (20 kHz) to spray very fine droplets of the solute-containing solution into a continuous flow of antisolvent which induces immediate crystallizati...

Stable ZnO nanoparticles suitable for further derivatization of their surface were synthesized in the liquid phase from homogeneous ethanolic solutions of the precursors, lithium hydroxide and zinc acetate. The particle growth was monitored by in situ absorption spectroscopy and dynamic light scattering (DLS). It was found that the growth of the particles was governed by temperature as well as ...
