What are aerosols?
An aerosol is a collection of solid particles or liquid droplets dispersed in air. Examples include smoke, fog, sea spray and pollution particles from vehicles. Particle sizes can range from the nanometre (a millionth of a millimetre) to the millimetre scale. Aerosols influence health, visibility, and global climate and find technological application in the delivery of drugs to the lungs, the engineering of nanostructures through spray drying, and the delivery of fuels for combustion.
As well as addressing some of the challenges faced in understanding the properties of aerosols, we use aerosols to study some broader ranging fundamental topics in physical chemistry/chemical physics.
