SYSTEMS AND METHODS FOR PREPARING NANOCRYSTALLINE COMPOSITIONS USING FOCUSED ACOUSTICS
摘要
Methods and systems for preparing nanocrystalline compositions using focused acoustic processing to cause and/or enhance crystal growth. A flow through system may be employed to expose sample material having a volume of greater or less than 30 mL to focused acoustic energy while flowing through a process chamber at a rate of at least 0.1 mL/min. Sample material may be processed by a suitable focused acoustic field in a cyclic fashion and/or with adjustment of processing parameters based on monitored characteristics of the sample, such as level of crystallinity. Nanocrystalline particles within the sample may have a tight particle size distribution with an average particle size between 10 nm and 1 micron. Stable nanocrystalline compositions may be reproducibly prepared using focused acoustics to have controllable morphologies and dimensions.
