Combinatorial Mapping of Polymer Blends Phase Behavior

January 1, 2003
Author(s)
Alamgir Karim, A Sehgal, Eric J. Amis, J C. Meredith
Methodologies for phase behavior characterization allow for discovery of new models for structure-processing-property relationships in polymer blends. Several recent developments were presented in the combinatorial characterization of polymers blends phase

Combinatorial Mapping of Surface Energy Effects on Diblock Copolymer Thin Film Ordering

January 1, 2003
Author(s)
A P. Smith, A Sehgal, Jack F. Douglas, Alamgir Karim, Eric J. Amis
Combinatorial gradient techniques are used to map the thin film morphology dependence of symmetric diblock copolymers as a function of film thickness and substrate surface energy. An inversion from symmetric to asymmetric lamellar morphology is observed as

Comparing Mass Spectra: When Do They Match?

January 1, 2003
Author(s)
Stephen E. Stein
A common method of determining the identity of a compound is to compare its spectrum against a known standard spectrum of the same substance. Comparisons can be made based on a variety of criteria. How does an analyst know that a match has occurred when

Comparison Of The Complete Mtdna Genome Sequences Of Human Cell Lines - Hl-60 And Gm10742a - From Individuals With Pro-Myelocytic Leukemia And Leber Hereditary Optic Neuropathy, Respectively, And The Inclusion Of Hl-60 In The Nist Human Mitochondrial Dna

January 1, 2003
Author(s)
Barbara C. Levin, K A. Holland, Diane K. Hancock, Michael Coble, T. J. Parsons, L J. Kienker, D W. Williams, M P. Jones, K L. Ritchie
Forensic and clinical laboratories benefit from DNA Standard Reference Materials (SRMs) that provide the quality control and assurance that their results from sequencing unknown samples are correct. Therefore, the mitochondrial DNA (mtDNA) genome of HL-60

Computed Images of Dielectric Strips on a Substrate

January 1, 2003
Author(s)
Egon Marx
Accurate computed optical images of lines and trenches placed on semiconductors are of great interest to the manufacturers of computer components, especially in the overlay process for different layers. These images do not accurately reflect the form of
