Understanding the Decreased Segmental Dynamics of Supported Thin Polymer Films Reported by Incoherent Neutron Scattering

February 10, 2015
Author(s)
Changhuai Ye, Clinton G. Wiener, Madhu Sudan Tyagi, David Uhrig, Sara Orski, Christopher Soles, Bryan D. Vogt, David S. Simmons
Incoherent neutron scattering (INS) has commonly reported a suppression of segmental dynamics for supported thin polymer films as thickness is decreased, which is counter to expectations based on other measurement techniques such as ellipsometry and

Design and Implementation of Two-Dimensional Polymer Adsorption Models: Evaluating the Stability of Candida Antartica Lipase B at Solid-Support Interfaces by QCM-D

January 4, 2013
Author(s)
Sara V. Orski, Santanu Kundu, Richard Gross, Kathryn L. Beers
A two-dimensional model of a solid-supported enzyme catalyst bead is fabricated on a quartz crystal microbalance sensor to measure in situ stability and mechanical properties of Candida Antartica Lipase B (CAL B) layers under varied conditions relating to

SOLID-SUPPORTED ENZYME CATALYST MODELS FOR RING-OPENING POLYMERIZATION

April 27, 2012
Author(s)
Sara V. Orski, Santanu S. Kundu, Kathryn L. Beers, Richard A. Gross
The enzyme Candida antarctica Lipase B (CAL B), immobilized on a crosslinked poly(methyl methacrylate) (PMMA) support, catalyzes the ring-opening polymerization of ε-caprolactone to make biodegradable polyesters. Weak hydrophobic interactions of CAL B
