Crystallization of Isotactic Polystyrene in Thin Films: A High Throughput Approach

January 1, 2001
Author(s)
Kathryn L. Beers, Jack F. Douglas, Eric J. Amis, Alamgir Karim
Very thin films of semi-crystalline polymers are increasingly being employed in coatings applications and there is a need to better understand how film thickness and crystallization conditions influence the crystalline morphology and resultingfilm

Organic-Inorganic Hybrid Particles by Dendrimer Nanotemplating

January 1, 2001
Author(s)
F Gruhn, Barry J. Bauer, Eric J. Amis
Poly(amidoamine) (PAMAM) dendrimers are used to create organic-inorganic hybrid colloids in aqueous solution. The formation of gold colloids upon reduction of a gold salt precursor serves as a model reaction to study the influence of reaction conditions

Small-Angle Neutron Scattering From Metal Ion-Containing PAMAMOS Dendrimer Networks

January 1, 2001
Author(s)
Robert A. Bubeck, Barry J. Bauer, P Dvornic, M J. Owen, S Reeves, P Parkham, L W. Hoffman
There is considerable interest in the development of nanocomposites based on dendrimers as host matrices. The intent is to take advantage of functionalized dendrimer interiors that can complex with an added constituent, resulting in nanocomposites for

Structured Polymeric Templates: Combinatorial Probes for Cellular Response

January 1, 2001
Author(s)
A Sehgal, Jack F. Douglas, Francis W. Wang, Carl G. Simon Jr., Alamgir Karim, Eric J. Amis
Novel high-throughput gradient methods have been developed to generate a range of surface structures by dewetting and phase separation on chemically patterned substrates. The research is motivated by an increasing awareness in the biomedical industry and

Temperature Monitoring of Capillary Rheometry Using a Fluorescence Technique

January 1, 2001
Author(s)
Anthony J. Bur, S C. Roth, H Lobo
A non-contact temperature monitoring technique based on fluorescence spectroscopy was used to measure the temperature of a polymer resin during capillary rheometry testing. Polyethylene doped with a fluorescent dye, perylene, was used in experiments that
