Laser Spectroscopy of Jet-Cooled Ethyl Radical: Infrared Studies in the CH 2 Stretch Manifold

January 1, 2000

Author(s)

S Davis, D Uy, David Nesbitt

A glow discharge, slit supersonic expansion in conjunction with direct infrared laser absorption methods has been utilized to record high resolution vibration-rotation spectra of the CH 3-CH 2 ethyl radical. The slit supersonic expansion results in

Lattice Model of Living Polymerization. II: Interplay Between Polymerization and Phase Stability

January 1, 2000

Author(s)

J Dudowicz, Karl Freed, Jack F. Douglas

Representative spinodal curves and polymerization lines for the equilibrium polymerization of linear polymers in a solvent have been calculated using aFlory-Huggins type mean-field theory. The calculations are primarily restricted to systems that

Layer Perfection in Ultrathin InAS Quantum Wells in GaAs(001)

January 1, 2000

Author(s)

J A. Gupta, S P. Watkins, E D. Crozier, Joseph Woicik, D A. Harrison, D Jiang, I J. Pickering, B A. Karlin

X-ray diffraction (XRD), X-ray standing wave (XSW) and X-ray absorption fine structure (XAFS) measurements were used to assess the layer perfection and positions of 1 and 2 monolayer (ML) InAs quantum wells buried in GaAs(001). Photoluminescence (PL)

LCST Phase Separation in Biodegradable Polymer Blends: Poly(D,L-lactide) and Poly(e -caprolactone)

January 1, 2000

Author(s)

J C. Meredith, Eric J. Amis

A lower critical solution temperature (LCST) phase transition is reported for blends of the biodegradable polymers poly(D,L-lactide) (PDLA) and poly(ε-caprolactone) (PCL). From light scattering measurements the cloud point curve is determined to have a

Load History Dependence of Fracture in Rubber-Toughened Epoxies

January 1, 2000

Author(s)

Donald L. Hunston, J He, R Raghavan, D Hoffman

It is well know that the most common toughening mechanisms in structural adhesives are viscoelastic processes so the fracture energies for bulk adhesive specimens and bonded joints vary with loading history. The work here examines this effect by measuring

Matrix Clusters and Polymer-Matrix Adducts in the MALDI Analysis of Polystyrene

January 1, 2000

Author(s)

R J. Goldschmidt, Charles M. Guttman

The formation of matrix cluster ions and of polymer-matrix adduct ions in the matrix-assisted laser desorption/ionization (MALDI) analysis of polystyrene was investigated using layered sample preparations. It has been shown by post-source decay (PSD)
