Relationship between dispersion metric and properties of PMMA/SWNT nanocomposites

June 13, 2007
Author(s)
Takashi Kashiwagi, Jeffrey Fagan, Jack F. Douglas, Kazuya Yamamoto, N. Alan Heckert, Stefan D. Leigh, Jan Obrzut, Fangming Du, Minfang Mu, Sheng Lin-Gibson, K Winey, R Haggenmueller
Particle spatial dispersion is a crucial characteristic of polymer composite materials and this property is recognized as especially important innanocomposite materials due to the general tendency of nanoparticles to aggregate under processing conditions

Rapid Assessment of Dental Polymers Using Gradient Samples

April 18, 2007
Author(s)
Nancy J. Lin, Peter Drzal, Sheng Lin-Gibson
Dental composites are widely used yet still face challenges including incomplete conversion, polymerization shrinkage, and poor adhesion to tooth structures. High-throughput techniques to quickly assess several material properties in a combinatorial manner

Encapsulated Chondrocyte Response to Pulsatile Flow Bioreactor

August 16, 2006
Author(s)
James A. Cooper, W Li, L A. Bailey, Steven D. Hudson, Sheng Lin-Gibson, Kristi S. Anseth, Rocky Tuan, N Washburn
We have developed a bioreactor using microfluidic techniques that allow for dynamic culture conditions and measurement of the fluid flow impinging upon a three-dimensional (3-D) tissue engineering (TE) scaffold. Chondrocytes in scaffolds have been shown to

Combinatorial Method for Determining Optimum Tissue Scaffold Composition for Imaging by X-Ray Techniques

April 12, 2006
Author(s)
Carl G. Simon Jr., Yanyin Yang, Shauna M. Dorsey, Gary E. Schumacher, Glenn M. Flaim, J Kohn, Sheng Lin-Gibson, Matthew Becker
X-ray imaging techniques can be very useful for tissue engineering applications. The ability to image radiopaque medical implants in vivo with X-ray radiography enables clinicians to conveniently, inexpensively and non-invasively monitor wound healing and

Measuring the Modulus of Soft Polymer Networks via a Buckling-Based Metrology

April 1, 2006
Author(s)
Elizabeth A. Wilder, Shu Guo, Sheng Lin-Gibson, Michael J. Fasolka, Christopher Stafford
We present a new method for measuring the modulus of soft polymer networks (E 10 MPa).This metrology utilizes compression-induced buckling of a sensor film applied to the surface of the specimen,where the periodic buckling wavelength, assessed rapidly by

High-Throughput Evaluation of Restorative Dental Polymers

March 31, 2006
Author(s)
Sheng Lin-Gibson, Forrest A. Landis, Nancy J. Lin
The effects of co-monomer composition and irradiation time on material properties and cell response were determined using high-throughput and combinatorial methods. 2-Dimensional gradient samples varying in monomer composition and light exposure time were
