Generation and Deposition of Organic Nanoparticles in a Liquid Ring Pump

May 13, 2015


Over the years, the utilization of organic nanoparticles or nanosuspensions has become more and more important in the life science industry. In the pharmaceutical and food industries, nanoparticulate formulations of poorly water-soluble drugs may enhance dissolution rates and bioavailability. Furthermore, nanomaterials hold promise for the optimization of technological and physiological effectiveness of organic substances in the cosmetics industry and other industrial branches. Sokratis Sinanis et al. present a new aerosol-based bottom-up method for the generation and deposition of organic particles using a liquid ring pump. If a gas-vapor mixture is compressed in a liquid ring vacuum pump, the gas phase may become supersaturated with respect to the vapor and aerosol formation may occur. This principle was utilized for the well-aimed production of submicron- or nanoscale organic particles. Additionally, a simplified model was developed for the prediction of supersaturation profiles during the compression of a gas-vapor mixture in a liquid ring pump cycle.
