Parallel Geometric Classification of Stem Cells by Their 3D Morphology

July 1, 2013
Author(s)
Derek Juba, Antonio Cardone, Cheuk Y. Ip, Carl Simon Jr., Christopher K. Tison, Girish Kumar, Mary C. Brady
Autologous stem cells show great promise for tissue engineering as they can regenerate diseased or damaged tissue, without requiring an organ donor or causing immune rejection. A primary goal of regenerative medicine is to identify methods for controlling

Cellulose Nanomaterials: Nanocomposite Imaging using FRET

June 19, 2013
Author(s)
Jeffrey W. Gilman, Mauro Zammarano, Iulia A. Sacui, Jeremiah Woodcock
Cellulose is the most abundant organic polymer on Earth, found in plants (cotton, hemp, wood), marine animals (Tunicate), algae (Valonia) bacteria (Acetobacter xylium) and even amoeba (Dictyostelium discoideum). Critical features of the structural

Cubic Silsesquioxanes as Tunable High Performance Coating Materials

June 19, 2013
Author(s)
Christopher Soles, Hyun W. Ro, Aaron M. Forster, Dave J. Krug, Vera Popova, Richard M. Laine
In this manuscript a series of cubic silsequioxane monomers with their eight vertices functionalized with different organic ligands terminated with triethoxysilane groups were acid hydrolyzed, spin cast into thin films, and then vitrified into hard

Mechanochromic photonic gels

June 10, 2013
Author(s)
Edwin P. Chan, A M. Urbas, Joseph J. Walish, Edwin L. Thomas
Polymer gels are remarkable materials with physical structures that can adapt significantly and quite rapidly with changes in the local environmental changes such as temperature, light intensity, electrochemistry, and mechanical force. An interesting

Toward the Development of a High Strain Rate Testing Standard for Advanced Fibers

May 24, 2013
Author(s)
Gale A. Holmes, Jae Hyun Kim, Nathanael A. Heckert, Walter G. McDonough, Stefan D. Leigh, Kirk D. Rice
The use of advanced fibers in applications where they are subjected to extremely energetic events has necessitated the need to develop measurement tools that quantify their properties at high strain rates (HSR). The split Hopkinson tension bar (SHTB) has

Effects of fiber gripping methods on single fiber tensile tests: Parametric statistical analyses of tensile strengths and failure strains

May 9, 2013
Author(s)
Jae Hyun Kim, Nathanael A. Heckert, Walter G. McDonough, Kirk D. Rice, Gale A. Holmes
The Kolsky bar test has been widely used in measuring material response under high strain rate conditions. Initial experiments in the literature applying this test to measure single fiber properties for fibers used in soft body armor with the Kolsky bar

Gradient Nanofiber Scaffold Libraries for Screening Cell Response to Poly(e-caprolactone)-Calcium Phosphate Composites

March 1, 2013
Author(s)
Carl G. Simon Jr., Limin Sun, Laurence C. Chow, William Miles, Christopher K. Tison, Kaushik Chatterjee, Marian F. Young, Vinoy Thomas, Murugan Ramalingam
A 2-spinnerette approach has been developed for fabricating nanofiber scaffold gradients for use as 1) scaffold libraries for screening the effect of nanofiber properties on cell response and 2) templates for generating graded tissue interfaces. Although

Effects of fiber gripping methods on the single fiber tensile test: I. Non parametric statistical analysis

February 15, 2013
Author(s)
Jae Hyun Kim, Nathanael A. Heckert, Stefan D. Leigh, Haruki Kobayashi, Walter G. McDonough, Kirk D. Rice, Gale A. Holmes
Single fiber tensile tests using two different gripping methods were carried out on various fiber lengths. One method (the glue-tab grip) consists of mounting a fiber onto a rigid tab as specified in ASTM C1557-03 using an adhesive, while the other (the
