Short Course On Surfactants-Principles and Applications
April 19-21, 2010
University of Florida, Gainesville, FL
Registration will be open in
The Center for
Surface Science and Engineering
at the University of Florida was established by the Board of Regents of the
State University System as an interdisciplinary center for surface science and
engineering in January 1985. Presently, 14 faculty members from various
departments and colleges are involved in the activities of the Center. An
international advisory board of leading researchers from academia and industry
also provides input to the Center.
Engineering Research Center (PERC), was created to understand, monitor, and modify particle behavior of
particulate systems in existing and emerging industries. The Center’s primary
mission is to create a national center of excellence by conducting innovative
fundamental research in an intellectually stimulating environment to enhance
U.S. technological competitiveness, to educate students and professionals in the
engineering practice of particle science and technology and to promote academic,
industry, and government collaboration.
As one of their activities, the two centers
are jointly offering an intensive course on Surfactants: Principles &
Applications to research, development and technical staff of
industry. The course will present the principles and technological applications
of surfactants to participants from industry. It will consist of lectures,
laboratory experiments, and problem-solving sessions. Detailed lecture notes and
related reprints will be given to each participant. The course will also include
a guided tour of the state-of-the art research facilities available on the
University of Florida campus for surface science research. The teaching faculty
for this intensive course combines over 125 years of research and teaching
experience in surface and colloid science both from industry and academia.
we offer this intensive short course to technical staff of industry?
We have been offering this annual intensive
short course since 1984 in order to communicate the fundamental principles as
well as recent advancements of surface science and technology to technical staff
of industry. The science and technology involving surfactants have rapidly grown
over the years. New methodologies and instruments have been designed to study
the various properties of surfactant films, micelles and solutions.
This course also offers an opportunity for our
students and postdoctoral associates to directly interact with technical staff
from industry by setting aside an entire afternoon of the course to demonstrate
instruments or methods used to measure various properties of surfactant films,
micelles and solutions.
should take this intensive short course?
Any person involved in scientific and
technical activities involving surfactant formulations, processing, or product
design can benefit from this course.
We start with simple foundations of what
interfaces are as well as surfactant molecules and proceed to discuss the
development of surfactant science and applications in various technological
What topics are
included in this Course?
We discuss various fundamental parameters used
in surface and colloid chemistry as well as various systems and phenomena such
as monolayers, micelles, macro and microemulsions, foams, contact angle and
wettability, electrical double layer and electrokinetic phenomena, zeta
potential, nanoparticles, dispersions, filtration of viruses, bacteria and
nanoparticles. Detailed topics are described elsewhere in this brochure.
We also have a series of experiments to
demonstrate the measurement of various properties of surfactant solutions such
as dynamic surface tension, surface viscosity, Langmuir Blodgett films,
retardation of evaporation by monolayers, size distribution in microemulsions,
formation of microemulsions, zeta potential measurement, atomic force
microscopy, and BET Surface area measurement of powders.
What is the uniqueness of this intensive
Based on our collective experience of more
than 125 years, we emphasize the strong correlations between the molecular
properties of surfactants and their macroscopic behavior in foams, emulsions,
wettability, solubilization, and other technological processes and systems.
Thus, interrelating the molecular structure of
surfactants and their behavior in various technological processes is a unique
and strong aspect of this course.
Each participant will receive a detailed
volume of lecture notes and an additional volume of important reprints of papers
on various topics that illustrate the concepts presented in the lectures.
