INDENTATION AND ADHESION AT SMALL LENGTH SCALES

June 1, 2011
Author(s)
Robert F. Cook
Indentation and adhesion are considered in the context of the two experimental methods predominantly used to measure contact behavior at small length scales, instrumented indentation testing and atomic force microscopy. The typical loads and displacements

The Effect of Folding on the Internal Structure of Ballistic Fibers

May 26, 2011
Author(s)
Haruki Kobayashi, Walter G. McDonough, Hae-Jeong Lee, Jae H. Kim, Amanda L. Forster, Kirk D. Rice, Gale A. Holmes
In one of our previous studies, the mechanical properties of poly (p-phenylene benzobisoxazole) (PBO) fibers were degraded when the fibers were folded. When we examined poly (p-phenylene terephthalamide) (PPTA) fibers, we did not find a similar drop in

Hyperbranched Poly(ethylene oxide) Electrolytes for Lithium Ion Batteries

May 17, 2011
Author(s)
Christopher L. Soles, Kirt A. Page, Huagen H. Peng
This work demonstrates the capability of hyper-branched PEO polymers to act as a polyelectrolyte for Li-ion batteries. Hyperbranching has been shown to lead to a 100 fold increase in the ion conductivity below the melting temperature of the PEO

Imaging Cells in Polymer Scaffolds by X-Ray Microcomputed Tomography

May 11, 2011
Author(s)
Shauna M. Dorsey, Sheng Lin-Gibson, Carl Simon Jr.
We have investigated the ability of X-ray microcomputed tomography (CT) to make quantitative, three-dimensional (3D) measurements of cell adhesion and proliferation in polymeric tissue engineering scaffolds. The most common method for examining cells in

Combinatorial Screening of Hydrogel Scaffolds for 3D Cell Culture

May 2, 2011
Author(s)
Kaushik Chatterjee, Marian F. Young, Carl Simon Jr.
Optimizing cell-material interactions is critical towards maximizing regeneration in tissue engineering. Combinatorial and high-throughput (CHT) methods can be used to systematically screen tissue scaffolds to identify optimal biomaterial properties

A new interface defect spectroscopy method

April 26, 2011
