11. Pronounced micro-segregation in a sorbitol water mixture observed through variable temperature neutron scattering
Topic: Polymers
Published: 5/16/2012
Authors: Shin G Chou, Sheila Khodadadi, Joseph E Curtis, Susan T Krueger, Evgenyi Shalaev, Alan Soper, Andy Fitch, T Narayanan, Michael Szutucki, Marcus T Cicerone
Abstract: In this study, we use small and wide angle X-ray and neutron scattering measurements, to study the structure of concentrated sorbitol solutions and glasses at different temperatures. The analysis of the data suggests the water forms clusters with a ...

12. Optimization of Imaging Polymer Based Scaffolds Using X-Ray Microcomputed Tomography
Topic: Polymers
Published: 5/15/2012
Authors: David E, Morris, Melissa L Mather, Carl George Simon Jr, John A Crowe
Abstract: The performance of polymer based scaffolds used in regenerative medicine is linked to their structural properties and as such strategies for structural characterization of scaffolds have been developed. X-ray microscopic computed tomography (X-ray ...

13. Neutron reflectivity characterization of the photoacid reaction-diffusion latent and developed images of molecular resists for extreme-ultraviolet lithography
Topic: Polymers
Published: 5/11/2012
Authors: Vivek M Prabhu, Shuhui Kang, Wen-Li Wu, Sushil K Satija, Christopher K. Ober, Jing Sha, Peter V. Bonnesen
Abstract: Lithographic feature size requirements have approached a few radius of gyration of chemically-amplified photoresist polymers used in thin film patterning. Further, the feature dimensions are commensurate with the photoacid diffusion length that defin ...

14. Gas-Foamed Scaffold Gradients for Combinatorial Screening in 3D
Topic: Polymers
Published: 5/1/2012
Authors: Carl George Simon Jr, Kaushik Chatterjee, Alison McGibbon Kraigsley, Joachim Kohn, Durgadas Bolikal
Abstract: Current methods for screening cell-material interactions typically utilize two-dimensional (2D) culture format where cells are cultured on flat surfaces. However, there is a need for combinatorial and high-throughput screening methods to systematica ...

15. Osteoblast Response to Serum Protein Adsorption in 3D Polymer Scaffolds
Topic: Polymers
Published: 5/1/2012
Authors: Carl George Simon Jr, Girish Kumar, Kaushik Chatterjee, Stevephen Hung
Abstract: 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 ...

16. Nano-Apatitic Composite Scaffolds for Stem Cell Delivery and Bone Tissue Engineering
Topic: Polymers
Published: 4/15/2012
Authors: Hockin H. K. Xu, Carl George Simon Jr
Abstract: The need for bone defect repair and regeneration arises from trauma, disease, congenital deformity, and tumor resection. Bone fracture occurs to seven million people each year in the United States, and musculoskeletal conditions cost $215 billion ann ...

17. Photoiniated wrinkles with controlled morphology from a liquid coating on a rigid substrate: A facile route to tunable, periodic structures
Topic: Polymers
Published: 3/27/2012
Authors: Jessica M. Torres, Christopher M Stafford, Vogt D Bryan
Abstract: Periodic wrinkled surfaces have generated significant interest over the past decade as these structures can be easily fabricated over large areas with minimal fabrication cost, but these structures have been generally been limited to thin films on so ...

18. Relationship between Barrier Layer Tg and TFC Membrane Performance: Effect of Chlorine Treatment
Topic: Polymers
Published: 3/8/2012
Authors: Sajjad H. Maruf, Dae U. Ahn, John Pellegrino, Jason Philip Killgore, Alan R. Greenberg, Yifu Ding
Abstract: Thin film composite (TFC) reverse osmosis (RO) membranes play a significant role in addressing rapidly expanding global needs for potable water. A well-known problem of TFC membranes is their sensitivity to oxidizing agents such as chlorine, whi ...

19. Freeform Fabricated Scaffolds with Roughened Struts that Enhance both Stem Cell Proliferation and Differentiation by Controlling Cell Shape
Topic: Polymers
Published: 3/1/2012
Authors: Girish Kumar, Carl George Simon Jr, Michael S. (Michael Stephan) Waters, Tanya M. Farooque, Marian F Young
Abstract: We demonstrate that imparting freeform fabricated (FFF) scaffolds with surface roughness on their struts enhances osteogenic differentiation of primary human bone marrow stromal cells (hBMSCs) by controlling cell shape. Previous work showed that hBM ...

20. A Robust and High-Throughput Measurement Platform for Monomer Reactivity Ratios from Surface-Initiated Polymerization
Topic: Polymers
Published: 2/23/2012
Authors: Kirt Anthony Page, Derek Patton, Emily Hoff, Michael J Fasolka, Kathryn L Beers
Abstract: This article describes a robust approach to measure monomer reactivity ratios from surface-initiated copolymerization, by measuring composition of statistical copolymer brush surfaces using x-ray photoelectron spectroscopy. Statistical copolymer br ...
