481. Temperature Effects During Capillary Rheometry Testing
Topic: Polymers
Published: 5/1/2002
Authors: Anthony J. Bur, S C Roth, H Lobo
Abstract: 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 and polycarbonate doped with a fluorescent dye, perylene, were ...

484. Templating Nanocrystals with Dendrimers: A Mesoscopic Model System
Topic: Polymers
Published: 3/1/2000
Authors: Franziska Grohn, Barry J. Bauer, Eric J. Amis
Abstract: Poly(amidoamine) (PAMAM) dendrimers of generation 2 to 10 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 model reaction to study influences on ...

485. Terahertz Mobility Measurements on P3HT Films: Device Comparison, Molecular Weight and Film Processing Effects
Topic: Polymers
Published: Date unknown
Authors: Okan Esenturk, Joseph S Melinger
Abstract: We report the first direct comparison of relative carrier mobilities in semiconducting organic polymer films measured using non-contact optical pump terahertz probe spectroscopy to those reported in electrical device studies. Relative transient sign ...

486. Tertiary Structure Changes in Albumin Upon Surface Adsorption Observed Via Infrared Spectroscopy
Topic: Polymers
Published: 3/10/2009
Authors: Jack R Smith, Marcus T Cicerone, Curtis W Meuse
Abstract: A non-destructive infrared (IR) spectroscopy assay is used to measure changes the tertiary structure of Bovine Serum Albumin (BSA) adsorbed to three surfaces: gold, polystyrene (PS) and poly(D,L-Lactic acid) (PDLLA). Polymers are spin-coated onto a ...

488. The Bromine Doping of Polyacetylene
Topic: Polymers
Published: 4/1/2003
Author: C. K. Chiang
Abstract: The first doping experiment of polyacetylene performed by Chiang and Shirakawa in 1976 is described. The first successful doping experiment of polyacetylene impacted physics and chemistry in three aspects: 1) discovery of metallic conducting synth ...

490. The Effect of Temperature on the Morphology and Kinetics of Surface Pattern Formation in Thin Block Copolymer Films
Topic: Polymers
Published: 10/29/2007
Authors: A P Smith, Jack F Douglas, Eric J. Amis, Alamgir Karim
Abstract: Hole formation and size evolution on the surface of thin films of symmetric diblock copolymers is simultaneously investigated as a function of time, t, temperature, T, and film thickness, h. The hole size h approaches a steady state value at long ti ...
