Microwave Characterization of Transparent Conducting Films

May 26, 2011
Author(s)
Jan Obrzut, Oleg A. Kirillov
The high frequency conductivity of thin metallic and graphitic nano-films attracts interest due to many potential applications in spin electronics, electromagnetic shielding, flexible antennas, displays, and solar cells. The surface morphology of thin

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

Anemia, Hypothyroidism and Immune Suppression Associated with Polychlorinated Biphenyl Exposure in Bottlenose Dolphins (Tursiops truncatus)

May 25, 2011
Author(s)
John Kucklick, Lori Schwacke, Eric Zolman, Brian C. Balmer, Sylvain De Guise, Clay George, Jennifer Hoguet, Steve Lamb, Milton Levin, J. L. Litz, W E. McFee, Ned Place, Forrest Townsend, Teresa Rowles, Randall Wells, Aleta Hohn
Background: Polychlorinated biphenyls (PCBs) and other legacy organohalogens are often monitored in marine mammals both to understand health risks for populations of these protected species and as an indication of marine food web contamination. Bottlenose

Fluid interactions with metafilm/metasurfaces for tuning, sensing, and microwave assisted chemical processes

May 25, 2011
Author(s)
Joshua A. Gordon, Christopher L. Holloway, James C. Booth, James R. Baker-Jarvis, David R. Novotny, Sung Kim, Yu Y. Wang
In this paper we demonstrate tunability of a metafilm, which is the two-dimensional equivalent of a metamaterial, also referred to as a metasurface, by changing the permittivity in a micro-fluidic channel that interacts with the metafilm. Numerical

Redox-Promoting Protein Motions in Rubredoxin

May 24, 2011
Author(s)
Jose M. Borreguero, Junhong He, F. Meilleur, Kevin Weiss, Craig Brown, D. A. A. Myles, Kenneth W. Herwig, Pratul K. Agarwal
Abstract Proteins are dynamic objects, constantly undergoing conformational fluctuations, yet the linkage between internal protein motion and function is widely debated. This manuscript reports on the characterization of temperature-activated collective

A High Resolution High-Sensitivity Standoff Imaging System at 350 GHz

May 23, 2011
Author(s)
Daniel T. Becker, Cale Gentry, James A. Beall, Hsiao-Mei Cho, William Duncan, Gene C. Hilton, Kent D. Irwin, Peter J. Lowell, Michael D. Niemack, Nicholas G. Paulter Jr., Carl D. Reintsema, Francis J. Schima, Robert E. Schwall, Peter Ade, Carole Tucker, Simon Dicker, Halpern Mark
Millimeter wavelength radiation holds promise for detection of security threats at a distance, including suicide bomb belts and maritime threats in poor weather conditions. The sensitivity provided by superconducting Transition-Edge-Sensor (TES) bolometers
