Combinatorial Materials Science: What's New Since Edison?

April 1, 2002
Author(s)
Eric J. Amis, X D. Xiang, J C. Zhao
Combinatorial methods, or high throughput experimentations, have captured the attention of the materials industry due to the promise of providing new discoveries faster, better, and cheaper. However, in the scientific community combinatorial methods have

Combinatorial Methods for Investigations in Polymer Materials Science

April 1, 2002
Author(s)
J C. Meredith, A P. Smith, A J. Crosby, Eric J. Amis, Alamgir Karim
Combinatorial methods of drug discovery in pharmaceuticals research are well known and more recent applications have led to the discovery and synthesis of new inorganic materials, catalysts, and organic polymers. Polymeric coatings play an important role

Influence of Processing Rate and Formulation on the Interface Strength of Vinyl Ester/E-Glass Composites

April 1, 2002
Author(s)
Walter G. McDonough, Joy Dunkers, Gale A. Holmes, E Feresenbet, Y H. Kim, Richard~undefined~undefined~undefined~undefined~undefined Parnas
The single fiber fragmentation test was used to investigate the effect of gelation time on interfacial shear properties of fast reacting resin systems. We developed a processing system capable of producing single fiber fragmentation samples with gelation

Non-Equilibrium Pattern Formation in the Crystallization of Polymer Blend Films

April 1, 2002
Author(s)
V Ferreiro, Jack F. Douglas, James A. Warren, Alamgir Karim
The crystallization of polymeric and metallic materials normally occurs under conditions far from equilibrium. The morphologies formed reflect a competition between order associated with the symmetries of the equilibrium crystal geometry and disorder

DNA Hydrogel Plugs Immobilized in Microfluidic Channels with Improved Stability

February 28, 2002
Author(s)
Rebecca A. Zangmeister, K G. Olsen, David J. Ross, Michael J. Tarlov
It has been previously demonstrated that DNA, modified on the 5' end with an acrylic acid group, can be incorporated into a polyacrylamide hydrogel matrix. These types of DNA containing gels have recently been immobilized in plastic microfluidic channels

Combinatorial Assay of Cells on Topographically Patterned Surfaces

February 1, 2002
Author(s)
S L. Kennedy, N Washburn, A Sehgal, Alamgir Karim, Eric J. Amis
It has been well established that cell substrate topography can affect cell morphology and cell behavior. Numerous groups have demonstrated that cell alignment, anisotropic cell spreading and cell proliferation can be controlled by various topographical

Data Analysis Methods for Synthetic Polymer Mass Spectrometry: Autocorrelation

February 1, 2002
Author(s)
William E. Wallace, Charles M. Guttman
Autocorrelation is shown to be useful in describing the periodic patterns found in high-resolution mass spectra of synthetic polymers. Examples of this usefulness are described for a simple linear homopolymer to demonstrate the method fundamentals, a

Combinatorial Mapping of Polymer Film Wettability on Gradient Energy Surfaces

January 1, 2002
Author(s)
K M. Ashley, A Sehgal, Eric J. Amis, D T. Raghavan, Alamgir Karim
The use of combinatorial methods for studying dewetting of thin hydrophobic polystyrene (PS) and hydrophilic poly d-lacticacid (PDLA) films on chemically modified gradient energy surfaces was studied. Substrate libraries were prepared by immersing Si-H

Near-Field Optical Imaging of Microphase Separated and Semi-Crystalline Polymer Systems

January 1, 2002
Author(s)
Michael J. Fasolka, Lori S. Goldner, A Urbas, Jeeseong C. Hwang, Kathryn Beers, P DeRege, Evan L. Thomas
Polymer self-assembly presents an attractive means of creating the micro- and nano-patterned spatial arrays required for many opto-electronic and coatings technologies. Two of these ordering processes are microphase separation (MS), exhibited by block
