Laboratory Perspectives on the Chemical Transformations of Organic Matter in Atmospheric Particles

摘要

People have long ago discovered the effects of oil on the surface properties of water.~1.2 Lisbon seamen dropped oil from their boats to suppress the breakers when they returned to the harbor.Bermudan divers used to spread oil on the surface of the water toenable penetration of light to the depths,and the prot of Newport (Rhode Island0 always had calm waters while the whaling vessels were docked.In a famous experiment,Benjamin Franklin spread a teaspoon of oil over a lake in Calpham's common and noticed that the oil spread dramatically,forming a film so thin that it produced what he termed "prismatic colors".In light on wter surfaces,it is no surprise that the effects of organic compounds on the properties of atmospheric aerosols and cloud dropelts are so significant and are the focus of modern research in atmospheric chemistry.
