Outstanding Publication Award

The 2018 Aerosol Science and Technology (AS&T) Outstanding Publication Award recognizes Peng Liu, Paul J. Ziemann, David B. Kittelson, and Peter H. McMurry for their 1995 article titled “Generating Particle Beams of Controlled Dimensions and Divergence: I. Theory of Particle Motion in Aerodynamic Lenses and Nozzle Expansions” (Aerosol Science and Technology 22: 293–313). Along with its companion article, “Generating Particle Beams of Controlled Dimensions and Divergence: II. Experimental Evaluation of Particle Motion in Aerodynamic Lenses and Nozzle Expansions” (Aerosol Science and Technology 22:314–324), the article describes the theory and construction of an apparatus that can generate a collimated and tightly focused particle beam. The invention has been critical for enabling the detection of particle chemical composition via mass spectrometry methods, which have come to define the modern era in the field of aerosol chemistry.
