The Effect of Environmental and Mechanical Mechanisms on the Performance of Soft Body Armor

July 27, 2009
Author(s)
Gale A. Holmes, Eun S. Park, Jae Hyun Kim, Walter G. McDonough, John R. Sieber, Haruki Kobayashi, Michael A. Riley, Kirk D. Rice
The use of high performance fibers (such as, poly[(benzo-[1,2-d;5,4-d ]-benzoxazole-2,6-diyl)-1,4-phenylene]1 (PBO), ultra-high molecular weight polyethylene2 (UHMWPE), and poly(p-phenylene terephthalamide)3 (PPTA)) in soft body armor (SBA) is well

Characterization of Fly Ash Reactivity in Hydrating Cement by Neutron Scattering

July 14, 2009
Author(s)
W Bumrongjaroen, Richard A. Livingston, Dan A. Neumann, Andrew J. Allen
A combination of small-angle and inelastic neutron scattering studies are presented to elucidate the different effects of Class F and Class C fly ash additions on microstructure development in hydrating cement (and concrete). Small angle neutron scattering

Thermoelectric and Structural Characterization of Ba2Ho(Cu3-xCox)O6+y

June 13, 2009
Author(s)
Winnie K. Wong-Ng, Z Yang, Y F. Hu, Qingzhen Huang, Nathan Lowhorn, Makoto Otani, James A. Kaduk, Martin L. Green, Q Li
The search for thermoelectric materials for power generation and for solid-state cooling have led to the increased interest of layered cobalt-containing oxides because of their thermal stability at high temperature and their desirable thermoelectric

Myocardial Calcification in Captive Grouper Epinephelus Aeneus

June 1, 2009
Author(s)
Naomi Eidelman, A Colorni, Jirun Sun, M.C. Fishbein, A Diamant
A case of myocardial calcification is described in the Mediterranean white grouper, Epinephelus aeneus, cultured as broodstock in Eilat (Israel, Red Sea). Large calcified nodules and scar tissue were observed in the ventricular tissues. The chemical

Capillary Instability in Nanoimprinted Polymer Films

May 21, 2009
Author(s)
Kyle J. Alvine, Yifu Ding, Hyun Wook Ro, Brian C. Okerberg, Alamgir Karim, Christopher L. Soles, Jack F. Douglas
Capillary forces play an active role in defining the equilibrium structure of nanoscale structures. This effect can be especially pronounced in soft materials such as polymers near or above their glass transition temperatures where material flow is

An Instrumented Bioreactor for Cartilage Tissue Engineering

April 29, 2009
Author(s)
Timothy P. Quinn, Colm Flannery, Damian S. Lauria, Douglas V. Gallagher, Kristi S. Anseth
Bioreactors for in vitro growth of engineered tissue (ET) would ideally include sensors that would continuously measure the functional quality of the construct during incubation. Principles of feedback control could then be used to optimize properties of
