Osteoblast Response to Serum Protein Adsorption in 3D Polymer Scaffolds

May 1, 2012
Author(s)
Carl G. Simon Jr., Girish Kumar, Kaushik Chatterjee, Stevephen Hung
Protein adsorption is known to direct biological response to biomaterials and is important in determining cellular response in tissue scaffolds. In this study we investigated the effect of adsorbed serum proteins on cell attachment and proliferation in

Ultra-Small-Angle X-ray Scattering-X-ray Photon Correlation Spectroscopy: A New Measurement Technique for in-situ Studies of Equilibrium and Nonequilibrium Dynamics

May 1, 2012
Author(s)
Fan Zhang, Andrew J. Allen, Lyle E. Levine, Jan Ilavsky, Gabrielle G. Long
Ultra-small-angle X-ray scattering—X-ray photon correlation spectroscopy (USAXS-XPCS) is a novel measurement technique for the study of equilibrium and slow nonequilibrium dynamics in disordered materials. This technique fills an existing gap between the

Response of large area avalanche photodiodes to low energy X-rays

April 30, 2012
Author(s)
Thomas R. Gentile, Uwe Arp, M J. Bales, R Farrell
For an experiment to study neutron radiative beta-decay, we operated large area avalanche photodiodes (APDs) at liquid nitrogen temperature to detect X-rays with energies between 0.2 keV and 15 keV. Whereas there are numerous reports of X-ray spectrometry

Guidelines for reporting of phase equilibrium measurements (IUPAC Recommendations 2012)

April 27, 2012
Author(s)
Robert D. Chirico, Theodoor W. de Loos, Juergen Gmehling, Anthony R. Goodwin, Sumnesh Gupta, Kenneth N. Marsh, Calvin Spencer, Martin P. Trusler, William M. Haynes, Vicente Rives, Joan F. Brennecke
Recommendations are given for reporting in the primary scientific literature of measurements involving phase equilibrium. The focus is on documentation issues, and many of the recommendations may also be applied to the more general fields of thermodynamic

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
