2nd Conference 2011: Tutorials

In addition to regular sessions, tutorials with particular focus will be facilitated by leaders in the field of aerosol science and engineering. These will run approximately 100 minutes in duration, and are included with the conference registration fee.

  • Diesel Engine Emissions Control

Antonio H. Miguel, The  Huntington Botanical Gardens, San Marino,  CA

Abstract:  This tutorial summarizes the key developments in diesel emission control. Examples from the spectrum of technologies will be presented, including diesel NOx control developments on selective catalytic reduction (SCR), lean NOx traps (LNT) and lean NOx catalysts (LNC), along with important developments on diesel particulate filters (DPFs), and oxidation catalysts.

Currently Dr. Miguel is an air pollution specialist at the California EPA - ARB Haagen-Smit Laboratory in El Monte, CA.. His research focuses on aerosol measurement and behavior. For over a decade he has also been interested in the development of in situ methods for measuring physical and chemical properties of complex aerosol particles, such as found in Secondary Organic Aerosol (SOA).

  • Aerosol Science and Technology in Materials Synthesis

Renato P. Camata, Department of Physics, University of Alabama at Birmingham, Birmingham, AL, U.S.A., and Universidade Federal do ABC, Sao Paulo., Sao Paulo

Abstract:  Aerosol science and technology provides a flexible platform for materials fabrication. Aerosol routes are used to synthesize materials in the form of micro- and nanopowders, colloidal suspensions, nanostructured surfaces, and thin films, among others. This tutorial will provide an overview of the broad range of aerosol approaches and techniques used over the past two decades to create materials with applications in fields as varied as catalysis, optoelectronics, and cell biology.

Biographical Sketch:  Renato P. Camata completed his Ph.D. at the California Institute of Technology in 1997 and has worked as a researcher at the Institute of Physical and Chemical Research (RIKEN) in Japan and at the Institute of Physics of the University of São Paulo. Dr. Camata’s research is focused on the use of laser and aerosol processes in materials fabrication with current projects directed toward synthesis and properties of nanostructured ceramics for biomedical applications and semiconductor thin films for mid-infrared laser sources. He is currently a faculty member in the Department of Physics at the University of Alabama at Birmingham, while also serving as investigator in research projects at the Universidade Federal do ABC (UFABC) and at the Laboratório Nacional de Luz Síncrotron (LNLS).

  • Ambient Organic Aerosols

Sulekha Chattopadhyay, Independent Air Quality Professional, El Monte, California, USA

Abstract:  Particulate matter is the most easily recognizable form of air pollution since it can be observed, for example as smoke from stacks or dust on surfaces. Quantitative measurements of pollutant particles were apparently first made in the early 1900s. Since the beginning of the Industrial Revolution, global dependence on fossil fuels has resulted in serious air pollution episodes. Atmospheric particulate matter can be classified according to particle sizes. This leads to distinct modes that are a reflection of the emission sources. Organic aerosols having diameters less than 2μm degrade visibility and cause serious respiratory problems in humans. To alleviate these problems it is essential to understand their formation process. This presentation shows the measurement results of thermodynamic properties of aerosol forming compounds.

Biographical Sketch:  Sulekha Chattopadhyay received her Ph.D. from the University of California, Riverside, in 2004. She is the recipient of the Dean’s fellowship from UC‐Riverside. She is also the receipient of Guru Gobind Singh Fellowship for her graduate studies and Rotary International’s award during her undergraduate studies. Her interests are, understanding the fate and transport of particulate matter formed from secondary processes. Sulekha has participated in various national and international conferences and chaired several sessions.

  • Field Studies: Design Considerations for Launching a Successful Campaign

Arantzazu Eiguren-Fernandez, Research Chemist Aerosol Dynamics, Inc. 935 Grayson Street, Berkeley, CA, USA

Abstract: Field campaigns are vital for collecting data that allows us to understand the variables that govern a particular environment, and to build a working model that can be used to assess how the different variables impact target communities.

Our dynamic atmosphere is highly variable and unstable. The study of spatial and temporal variations requires of a careful selection of locations, sampling methods and protocols, and sampling times. Some of the important points to consider when designing a field campaign may include:

* Consideration of the specific goals of the study and the questions that need an answer.
* Development of an effective sampling campaign taking into consideration factors such as: the number of sites and samples to be collected, and the kind of data needed, among others

Also important is the definition of the best method for handling, storing, and especially preservation of the collected samples, as the success or failure of the study may depend on the integrity of the samples prior to analysis.

Biographical Sketch:  Arantzazu Eiguren-Fernandez completed her Ph.D. in Analytical Chemistry in 2000, and joined a group of researchers working at the UCLA Southern California Particle Center as a Postdoctoral Researcher. Her research has been focused in characterizing the physical, chemical and toxicological properties of particulate matter and their relation with adverse health effects. Dr. Eiguren-Fernandez’s most recent projects involve the development of new portable field instruments, which are affordable and capable of measuring near- or real-time chemical species present in aerosol particles.

  •  Introduction to Aerosol Mechanics

Richard C. Flagan, Department of Chemical Engineering, California Institute of Technology, Pasadena, CA

Abstract: This course covers basic aerosol mechanics (particle motion) at an introductory level. Topics include the aerodynamics of single particles, Stokes law, settling velocity, slip correction, aerodynamic diameter, non-spherical particles, acceleration, relaxation time, stopping distance, impaction, electrical mobility, and aerosol sampling. We will also discuss the collective behavior of aerosols, e.g., Brownian motion, diffusion, deposition, filtration, condensation, and coagulation, and their effects on particle size distributions. The course covers theory and applications and is suitable for those new to the field and for others who want to brush up on the basics.

Biographical Sketch:  Richard C. Flagan is the McCollum/Corcoran Professor and Executive Officer for Chemical Engineering at the California Institute of Technology where he teaches chemical engineering and environmental science. He has served as president of AAAR and editor-in-chief of Aerosol Science and Technology. His research spans the field of aerosol science, including atmospheric aerosols, aerosol instrumentation, aerosol synthesis of nanoparticles and other materials, and bioaerosols. His many contributions to the field of aerosol science have been acknowledged with the Sinclair Award of the AAAR and the Fuchs Award.
