Sorensen Receives Recognition for Aerosol Research

Christopher Sorensen, university distinguished professor of physics, is the 2003 recipient of the David Sinclair Award presented by the American Association for Aerosol Research.


According to the association, the award recognizes sustained excellence in aerosol research and technology by an established scientist still active in his or her career.  The individual's research must have a lasting impact in aerosol science.   


Sorensen has researched aerosols for more than 10 years, focusing on the physical characterization of aerosol particles and their aggregation.  Aerosols are solid or liquid particles in a gas such as clouds or smoke.  When in a gas, they naturally bond to one another in chainlike networks, forming what is called an aggregate.


The application of his research is particularly important in the areas of global warming and visibility problems due to smog in large cities.  There are also various industrial applications including the production of carbon black, a substance made from soot that increases the durability of tires, and in the production of titania, the product that replaced lead in lead-based paint.


Sorensen's research has been used in the design of various instruments to measure the size of aerosol particles.
