Abstract: An aerosol represents a system of particles and droplets in the size range of 1 nm to 100 micrometer suspended in a gas. The aerosol discipline crosses a wide variety of topics of societal relevance ranging from nanotechnology to climate change. The modern science of aerosols was originally developed in Europe to understand natural phenomena such as the occurrence of clouds fog mist and the changes in the color of the sky. Over the last 50 years the subject has grown enormously being motivated by applications such as: Sprays Occupational hygiene Health effects of domestic and urban air pollution Novel material synthesis Long range transport of radioactivity during nuclear accidents Global warming potential and Implication to climate change. The fundamentals of the discipline are closely linked to theories of Nucleation Mesoscopic physics Population Balance Models Electro-mechanics Fluid mechanics and Turbulence. There are fascinating technological developments for detecting the nanometer sized particles or for removing them from air by using a combination of specialized theoretical and technical ideas. In this talk we will take a bird’s eye view of some of the important elements of this subject.Bio: Dr. Y.S. Mayya is an Adjunct Professor in the department of Chemical Engineering IIT Bombay. He was formerly associated with Bhabha Atomic Research Centre where he worked for over 37 years prior to his superannuation in 2012. His areas of research include Aerosol studies Nuclear & Radiation Safety and environmental science. Some of his notable contributions pertain to the theory of aerosol charging study of aerosol coagulation and mitigation technologies Development of aerosol instrumentation setting up Nuclear Aerosol Test Facility for conducting aerosol behavior experiments execution of large scale measurement programmes of radon in dwellings to assess radiation doses to general populations and radiation epidemiological studies. He has co-authored 156 refereed Journal papers several conference papers two books and three edited volumes and has mentored many young researchers both at the Bhabha Atomic Research Centre and at IIT Bombay. He was the secretary of the Indian Aerosol Science & Technology Association (1999-2005) President of the Asian Aerosol Research Assembly (2005-2007) and member of the Editorial Board of J Aerosol Science (2004-2014). He received the K.G. Vohra Memorial award from the Indian Association for Radiation protection and was nominated as an Aerosol Pioneer during the International Aerosol Conference (2018) organized by the American Association for Aerosol Research. This seminar is compulsory for students registered for course CL 702 or CL 704.
