Dr. Lennox E. Iton
Chemist - Materials Scientist
Dr. Iton joined Argonne National Laboratory in 1975 where
he worked initially on applications of nuclear magnetic resonance to
the study of adsorbates and catalysts. Since 1978, his work has involved
many aspects of molecular sieve materials research, including crystallization
and growth mechanisms, advanced characterizations of structure, bonding
and dynamics, adsorbate structure and dynamics, cluster encapsulation,
computer simulation and quantum chemical theory, and intracrystalline
catalysis mechanisms. He introduced the technique of extended x-ray
absorption fine structure spectroscopy (EXAFS) to the study of cation
bonding and complexation in molecular sieve zeolites, and introduced
the technique of small-angle neutron scattering to the study of gel
crystallization mechanisms in zeolite synthesis.
His current interests include the synthesis of ordered mesoporous materials
based on self-assembled templating aggregates, the incorporation of
electronic, magnetic, and photoactive characteristics in mesoporous
material frameworks, and the formulation of nanocomposites with encapsulated
inorganics, metallic nanoparticles, organic aggregates, and biomolecules.
At home, Dr. Lennox is very active in his community. He
has two sons-- one in high school and the other at the University of
Illinois (UIUC). For more details about his interests and community

Dr.. Iton grew up on the island of St. Vincent in the
West Indies, and received his pre-college education there. He obtained
a B.Sc with First Class Honours in Chemistry from McGill University
in Totonto in 1970. He did his graduate work in the group of Professor
John Turkevich at Princeton University, receiving a Ph. D. in Chemistry
in 1976. His thesis research was on electron paramagnetic resonance
spectroscopy studies of hydrogen atoms trapped and stabilized in solids,
and of rare earth ions exchanged in nanoporous crystalline zeolites.
He has co-authored over 80 publications. In 1990, he received
the DOE-BES Materials Sciences Award for work in Materials Chemistry
with Significant Implications for Department of Energy-Related Technologies.
In 1997, he shared the first PNGV (Partnership for a New Generation
of Vehicles) Award from the Department of Commerce and The Society of
Automotive Engineers.
