Spray Sonocrystallization
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...
متن کاملSonocrystallization and sonofragmentation.
The application of ultrasound to crystallization (i.e., sonocrystallization) can dramatically affect the properties of the crystalline products. Sonocrystallization induces rapid nucleation that generally yields smaller crystals of a more narrow size distribution compared to quiescent crystallizations. The mechanism by which ultrasound induces nucleation remains unclear although reports show th...
متن کاملUltrasound-Assisted Biodiesel Production in microreactors
The ultrasound-assisted (UA) soybean oil methanolysis using KOH as a catalyst was studied at different reaction conditions in a microreactor. Box–Behnken experimental design, with three variables, was performed and the effects of three reaction variables i.e. reaction temperature, catalyst concentration and the methanol-to-oil molar ratio on fatty acid methyl ester (FAME) yield were evaluated b...
متن کاملFusion-protein-assisted protein crystallization.
Fusion proteins can be used directly in protein crystallization to assist crystallization in at least two different ways. In one approach, the `heterologous fusion-protein approach', the fusion partner can provide additional surface area to promote crystal contact formation. In another approach, the `fusion of interacting proteins approach', protein assemblies can be stabilized by covalently li...
متن کاملUltrasound-assisted lipoplasty.
BACKGROUND Ultrasound-assisted lipoplasty (UAL) has been associated with particular types of complications and uncertain long-term effects arising from interactions between ultrasonic energy and living tissue. The present review seeks to address these issues. METHODS Search strategy Three search strategies were devised to retrieve literature from Medline, Current Contents, Embase and Cochrane...
