2nd Annual Mechanical Engineering Founders Day Aerosol Science and Technology as an Enabling Discipline: From Nanoparticles to Bioparticles
Prof. S. K. Friedlander Wednesday, April 30, 2003 Aerosol science and technology (AST) is an "enabling discipline": a good understanding of AST is needed to deal with many natural and industrial phenomena that range from global warming to inhalation therapy, from the manufacture of pigments, reinforcing fillers and optical fibers to nuclear reactor safety, and from bioterrorism to air pollution. In the last decade, start-up companies have emerged that manufacture specialty nanopowders by aerosol processes. We will explore trends in aerosol research paying particular attention to nanoparticle technology and to the development of instrumentation for on-line chemical and biological analysis. We will also discuss the dynamics of the formation of solid nanoparticles. Finally, the dynamics of strained nanoparticle chain aggregates represents an entirely new field of great potential importance to the synthesis of nanocomposite materials. Sheldon K. Friedlander is Parsons Professor of Chemical Engineering and Director of the Air Quality/Aerosol Technology Laboratory at UCLA. He and his students conduct research on the physics and chemistry of particles in gases (aerosols). His laboratory is currently working on the synthesis of nanoparticles of controlled particle size and the study of the dynamic behavior of nanoparticle chain aggregates. His research has applications to the manufacture of novel nanocomposite materials and to the environmental effects of emissions of chain aggregates (e.g. diesel emissions). Dr. Friedlander discovered that very small particles in gases tend to approach asymptotic size distributions independent of their initial properties. This work has had broad application in air pollution and fine particle engineering. He introduced the widely used method of receptor modeling for relating air quality to emissions sources. With his co-workers, he introduced the basic theoretical equations relating the size of individual ("primary") particles produced in high temperature gas phase processes to material properties and process conditions. This work is basic to process design in the manufacture of pigments and fillers. Dr. Friedlander has been a consultant to the Los Angeles Air Pollution Control District, Chairman of the National Research Council (NRC) Panel on the Abatement of Particulate Emissions from Stationary Sources and Chairman of the NRC Sub-Committee on Photochemical Oxidants and Ozone. He received the Colburn Award from the AIChE in 1959 and was a Fulbright Scholar in 1960 and Guggenheim Fellow in 1969, both at the University of Paris. In 1974, Dr. Friedlander was the recipient of the Alpha Chi Sigma Award from the AIChE. He received the AIChE Walker Award in 1979. He was elected to the National Academy of Engineering in 1975 in recognition of his work on the origins and control of particulate pollution. He is the author of SMOKE, DUST AND HAZE: FUNDAMENTALS OF AEROSOL DYNAMICS, 2nd Edition, Oxford University Press, and of over one hundred and eighty scientific papers. He was the first Chairman of the EPA Clean Air Scientific Advisory Committee (1978-1982) and a member of the EPA Science Advisory Board Executive Committee. In 1982, Dr. Friedlander was named first incumbent of the Parsons Chair in Chemical Engineering at UCLA. He received a 1984 Senior U.S. Scientist Award (Humboldt-Award) from West Germany. In 1990, he received the Fuchs Memorial Prize, the international award in aerosol science and technology, and in 1995 the Lawrence K. Cecil Award, AIChE Environmental Division and in 2000 the Christian Junge Award of the European Aerosol Society. He received the Lifetime Achievement Award of the AIChE Particle Technology Forum in 2001. |
