Abstract: Concerted efforts in the past decade have demonstrated the viability of spray-drying techniques to produce useful nanoparticles for drug delivery applications. Specific studies carried out in respect of the dependence of particle size and morphology on the system parameters have shown unexpected relationships. Besides, the studies have paved a way to perform an in-situ determination of the critical supersaturation solubility for the drug-solvent systems of interest. The models developed using these concepts seem to be capable of predicting the conditions for the onset of layering in lipid-drug systems.The need for control of particulate pollutants in industries, in dwellings and in outdoor atmospheres, calls for a mixed bag of technologies to suit particular needs. Well-known among existing technologies are the HEPA filtration systems and corona discharge based electrostatic precipitators and ionizer units. In order to enhance the specific charges on pollutant particles, alternative charging mechanism using electro-sprays could be useful. Investigations are being carried out to explore this possibility. In this talk, we discuss the studies conducted in our laboratory towards advancing our understanding of nanoparticle and droplet systems which form the key to the development of these technologies. Bio: Dr. Y.S. Mayya joined as an adjunct professor at the Department of Chemical Engineering in IIT Bombay in 2013 after his superannuation from the Bhabha Atomic Research Centre. For over the past four decades, he has pursued both experimental and theoretical studies in the field of aerosols and other areas in nuclear safety. He is now focusing on problems pertaining to aerosol generation, removal techniques and evolution dynamics for various applications. He has 160 journal publications to his credit. He was a member of the Editorial Board of Journal of Aerosol Science (2004-2014), President of Asian Aerosol Research Assembly (2005-2007) and was recognized as an aerosol pioneer by the International Aerosol Research Assembly in 2018. This seminar is compulsory for students registered for course CL 702 or CL 704.
