Fall 2001 Departmental Distinguished
Seminar Series
Madhav Datta
Electrochemical Processing Technology in Microelectronics
September 10, 2001
According to Mahav Datta, electrochemical processing has emerged
as a “technology of choice for the manufacturing of a variety of
electronic components.” Datta's work at the Intel Corporation focuses
on the application of electrochemical deposition and dissolution
processes in microelectronics. Datta described one such example
of his work, fabrication of flip-chip interconnect technology, to
underline the importance of continuing research in the electrochemical
material field, especially in the areas of nanostructures and nanotechnology.
Datta’s visit was hosted by Assistant Professor Elizabeth Podlaha.
Russell Dunn
Industrial Examples of Process and Product Design
October 5, 2001
The focus of Russell Dunn’s presentation was the past two decades’
development of process integration design tools that target reductions
in the operating and capital costs of chemical processes. A consultant
with McSwain Engineering, Inc., Dunn’s examples included an overview
of wastewater process designs identified and implemented within
Solutia, Inc. in 1999-2001 which illustrated the effectiveness of
these design tools for identifying economically attractive solutions.
Dunn’s visit was hosted by Professor Ralph Pike.
Prashant Kamat
Hydroxyl Radical Mediated Oxidation in Environmental Remediation
October 26, 2001
Prashant Kamat’s discussion involved advanced oxidation processes
such as photocatalysis, sonolysis, radiolysis, and UV/H2O2 and their
use in the degradation of environmentally hazardous chemicals. Kamat’s
work at the University of Notre Dame involves employing transient
absorption spectroscopy and product analysis to elucidate the mechanistic
and kinetic details of radical reactions that occur during the mineralization
of model organic pollutants. Kamat’s visit was hosted by Professor
K.T. Valsaraj.
John Siddall
Industrial Polymer Process Development
November 16, 2001
In his presentation, John Siddell (B.S. 1977) of Dow Chemical
noted that chemical engineers are ideally suited to the development
of commercial processes for polymer manufacture. The physical properties
of materials change tremendously during polymerization and reliable
management of these changes is a mechanical challenge. Siddell’s
presentation gave a tour of some of the problems in real industrial
polymer processes and how they can be solved. Siddall’s visit was
hosted by Professor Kerry Dooley.
Vijay John
Lipid Self-Assembly and the Templated Synthesis of Nanostructured
Materials
December 7, 2001
Vijay John’s discussion pointed out the ability of lipids to self-assemble
in a remarkable variety of microstructures that serve as scaffolds
and templates for the synthesis of nanostructured materials. Such
knowledge proves important in the synthesis of ceramics, polymers,
and polymer-ceramic and polymer-polymer nanocomposites and the shape
control of semiconductor and magnetic nanoparticles. John is a member
of the faculty at Tulane University.
