CV.doc - University of CincinnatiThe study aims at preparing relaxation exercises and identifying the impact of
such exercises on social interaction for golf players. It was hypothesized that
such exercises have an impact on golf players. Section two is literature review
dealing with social interaction, importance and causes, and importance of

Publications fall into 5 Main Areas (with selected examples): Nanostructured Materials and Fractals: In situ studies of nano-
structural growth dynamics using SAXS. Work has also focused on aerosol
synthesis of nano-structured ceramics using sol-gel chemistry, Aerosol Gel
Reactor. Application of small-angle scattering to characterization of nano-
structure in a wide range of materials including pyrolytic silica, titania
and carbon, layered silicates, zeolites. Extensive work has involved
structure property relationships for polymer/ceramic nanocomposites.
Recently we have worked on spray flame synthesis of supported gold
catalysts and in situ anomalous x-ray scattering measurements for
characterization of the growth dynamics of supported gold nano-clusters in

ray and neutron scattering to issues of polymer/polymer miscibility and
phase separation kinetics. Studies of the structural basis for shifts in
miscibility with tacticity. Investigations of the structural basis for
chain conformation and persistence in PDMS and poly(hydroxyalkonates),
examples of flexible and rigid chain polymers respectively with the goal of
developing a structural basis to long chain polymer thermodynamics.

Semicrystalline Polymers: Studies of the development of correlated
lamellar structure in a wide range of semi-crystalline polymer using small-
angle x-ray scattering. We have focused on quantification of lamellar
orientation in processed polymers such as polymer films and correlation of
3-d orientation with properties such as gas transport in polymer films.
This work has also been extended to polyolefin/layered silicate nano-
composites. Recent work has involved in situ studies of machine direction
orientation (MDO) post processed films using in situ x-ray scattering at
CHESS and SSRL.

Polymer Interfacial Properties: Developed a technique to measure the
glass transition in polymer films using the ellipsometer. Several papers
have also been published pertaining to chain conformation in thin films
using neutron reflectivity. Application of the ellipsometer to study the
dynamics of polymer films in thermal quench studies. The relaxation time
and viscosity of thin films can be determined in this measurement. Results
indicate that polymers in confined geometries deviate kinetically from bulk
chains with WLF features reminiscent of tactic analogues in very thin
