Title: Faraday Wave-Multiple Fourier Horn-Based Ultrasonic Droplet Formation and Applications

Chen S. Tsai


Formation of micro- and nano-droplets and their novel applications are of continued and broad interest. In this paper, the method that utilizes MHz Faraday waves driven by centimeter-sized multiple Fourier horn ultrasonic nozzles and the underlying science for formation of monodisperse micron-sized droplets and the resulting pocket-size nebulizers (Technology [2, 75-81, 2014]) are reported. Imminent application of the new technology to inhalation drug delivery and potential applications of the micron-sized droplets such as formation of nanoparticles via spray drying and spray pyrolysis are also discussed
