Surface Characterization of Thermoplastics
Sponsor:
Ford Motor Company
This project involves the near surface characterization of thermoplastics such as polypropylene blends as a function of processing condition. Optical microscopy, scanning electron microscopy, transmission electron microscopy, fine focused wide-angle X-ray scattering, and small angle X-ray scattering all used to provide a comprehensive understanding of |

Defects in Organic Semiconductors
Sponsor:
National Science Foundation
We are investigating the microstructure of structural defects in crystalline organic semiconductors. These materials are of current interest for flexible flat panel displays, radio-frequency ID tags, photovoltaics, and biosensors. Our work has focused on the high resolution imaging of vacancies, dislocations, and grain boundaries. We |

Conducting Polymer Coatings for Biomedical Devices
Sponsor:
National Institute of Health, U. S. Army
We are investigating the use of electrochemically deposited conducting polymers for creating soft, bioactive coatings for biomedical devices intended for interactions with living tissue. Examples include cortical probes designed to be implanted in the Central Nervous System, retinal implants for restoring blindness, and cochlear implants |

Multiphasic Nanoparticles and NanofibersWe are developing multiphasic nanoparticles and nanofibers using simultaneous electrospinning of multiple jets. These particles are of fundamental interest for self-assembly, for controlled drug delivery, and for photovoltaics. They are also of interest for tissue engineering, such as for directed regeneration of neurons. |
