As evidenced by the most recent Volkswagen clean diesel scandal, R&D in diesel engine emission control is urgent and important to the world, including Canada. Soot from diesel engines is a complex aerosol containing mainly carbonaceous particles with trace amounts of inorganic material and other adsorbed species. Soot particles range from 10 to 100s nanometers. As a major air pollutant that is associated with respiratory and cardiovascular diseases as well as lung cancers, soot is responsible for millions of premature death annually around the world. As a result, increasingly stricter legislations have been published globally to control soot emissions from diesel engines and research in diesel soot abatement technology has received much interest over the last few years.
