Droplet size prediction in the production of drug delivery microsystems by ultrasonic atomization
Microencapsulation processes of drugs or other functional molecules are of great interest in pharmaceutical production fields. Ultrasonic assisted atomization is a new technique to produce microencapsulated systems by mechanical approach. It seems to offer several advantages (low level of mechanical stress in materials, reduced energy request, reduced apparatuses size) with respect to more conv...
متن کاملAnalysis of Size Correlations for Microdroplets Produced by Ultrasonic Atomization
Microencapsulation techniques are widely applied in the field of pharmaceutical production to control drugs release in time and in physiological environments. Ultrasonic-assisted atomization is a new technique to produce microencapsulated systems by a mechanical approach. Interest in this technique is due to the advantages evidenceable (low level of mechanical stress in materials, reduced energ...
متن کاملEffects of Solution Physical Properties on Separation Characteristics in Ultrasonic Atomization
When the high power ultrasound irradiates the liquid, small liquid droplets are generated from the liquid surface. This phenomenon is called as ultrasonic atomization [1]. Recently, it has been reported that ethanol is concentrated from the aqueous solution by ultrasonic atomization [2-4]. Since ultrasonic atomization scarcely accompanies the phase change, this is a great advantage comparing wi...
متن کاملNano-Stereocomplexation of Polylactide (PLA) Spheres by Spray Droplet Atomization
A direct, efficient, and scalable method to prepare stereocomplexed polylactide (PLA)-based nanoparticles (NPs) is achieved. By an appropriate combination of fabrication parameters, NPs with controlled shape and crystalline morphology are obtained and even pure PLA stereocomplexes (PLASC) are successfully prepared using the spray-drying technology. The formed particles of varying D- and L-LA co...
متن کاملAn Experimental Study of Micron-scale Droplet Aerosols Produced via Ultrasonic Atomization
In the last 10 years, laser-driven fusion experiments performed on atomic clusters of deuterium have shown a surprisingly high neutron yield per joule of input laser energy. Results indicate that the optimal cluster size for maximizing fusion events should be in the 0.01–1 mm diameter range, but an appropriate source of droplets of this size does not exist. In an attempt to meet this need, we u...
