Aerosol Processing of Nanomaterials
INSTRUCTOR:Prof. Sheryl Ehrman, University of Maryland
DATES: August 20-22, 2007 [3 Day Course]
LOCATION: San Francisco, CA
In the quest for low cost production of nanomaterials for energy, microelectronics, biotechnology and other applications, gas phase or aerosol processes are arguably the best approach. The overall focus of this course will be aerosol processing of materials, with special emphasis on nanoparticle synthesis and multicomponent nanoparticles with tailored properties.
TUITION: US$1900.00
REGISTRATION: Closes July 18, 2007 or full.

COURSE DETAILS: The course will begin with an overview of the present day importance of
aerosol synthesis in industry, as well as a review of recent cutting edge
developments in nanoparticle synthesis coming out of the top international
research laboratories. With this framework in mind, the basic physical
phenomena that govern nanoparticle transport, nucleation, growth, and
final nanoparticle morphology will be described. Special attention will
be paid to the free molecular transport of nanoparticles, which differs
considerably from the continuum approach used typically to describe the
transport of larger particles in fluids, thermodynamics at the nanoscale,
and the interesting material properties at the nanoscale that influence
final particle morphology and chemical composition. Although the focus
of this course will not be on detailed simulation of nanoparticle
formation, the relationships between the above phenomena will be studied,
and simple criteria important for process feasibility and design will be
highlighted. On process design, different classes of aerosol reactors will be compared,
with discussion of respective advantages and drawbacks. Precursor
selection will be addressed from process safety and process economic point
of view. This information will be used as the basis for a discussion of
multicomponent materials synthesis, and the challenges of balancing
kinetics versus thermodynamics in order to obtain the desired properties
of interest. Last but not least in design, inertial, electrostatic and
filtration based approaches for nanoparticle collection will be reviewed. The course will be geared towards those with some experience and/or
education in engineering, chemistry or physics.
