Double-Resonance Lineshapes in a Cell with Wall Coating and Buffer Gas

June 28, 2010
Author(s)
Svenja A. Knappe, Hugh Robinson
Microwave double resonances were measured is a wall-coated Rb vapor cell as a function of additional buffer gas pressure. These data were compared to similar measurements in an uncoated cell. It was found that the linewidth in the coated cell displays a

Determination of Organic Acids in Vaccinium Berry Standard Reference Materials

June 27, 2010
Author(s)
Melissa M. Phillips, Lane C. Sander, Katherine E. Sharpless, Stephen A. Wise, Catherine A. Rimmer, Ryan Case, James H. Yen
Nine organic acids (citric acid, galacturonic acid, glycolic acid, isocitric acid, malic acid, oxalic acid, quinic acid, shikimic acid, and tartaric acid) and two anions (phosphate and sulfate) were determined in a suite of Vaccinium berry containing

Evolutionary Computation Approach to Heat Exchanger Design

June 26, 2010
Author(s)
David A. Yashar, Janusz Wojusiak, Kenneth Kaufman, Piotr A. Domanski
The efficiency of a vapor compression system is strongly influenced by the performance of the finned-tube heat exchangers it employs. Heat exchanger performance is strongly influenced by the refrigerant circuitry, i.e., the connection sequence of the tubes

Switching in Flexible Titanium Oxide Memristors

June 25, 2010
Author(s)
Joseph L. Tedesco, Nadine E. Gergel-Hackett, Laurie A. Stephey, Christina A. Hacker, Curt A. Richter
In this study, memristors were fabricated on flexible polyethylene terephthalate (PET) substrates with aluminum contacts and a titanium dioxide film formed with a sol-gel of titanium isopropoxide and ethanol. To study the electric field dependence of

Two modes behavior of vortex oscillations in spin-transfer nanocontacts subject to in-plane magnetic fields

June 25, 2010
Author(s)
Michaela Kuepferling, Claudio Serpico, Matthew Pufall, William Rippard, Thomas Mitchell (Mitch) Wallis, Atif A. Imtiaz, Pavel Kabos
The field dependence of vortex oscillations in a spin-transfer metallic nanocontact, subject to in-plane, spatially uniform, external fields, is studied by measuring the power spectral density of the voltage across the device. The measured spectra as a

Forced Assembly and Mixing of Melts via Planar Polymer Micro-Mixing

June 24, 2010
Author(s)
Doyoung Moon, Kalman D. Migler
The ability to force immiscible polymers into specific, targeted structures would enable the generation of blends with tailored performance by exploiting the intimate relationship between structure and blend properties. Here we present a strategy for the
