Thermal Conductivity of Monolayer MoS2 Obtained from Temperature-Dependent Raman Spectroscopy

December 30, 2013
Author(s)
Rusen Yan, Jeffrey R. Simpson, Simone Bertolazzi, Jacopo Brivio, Michael Watson, Xufei Wu, Andras Kis, Tengfei Luo, Angela R. Hight Walker, Huili G. Xing
Atomically thin molybdenum disulphide (MoS2) is emerging as a potential alternative to graphene due to presence of bandgap, which is particularly advantageous to optoelectronic applications. The temperature-dependent Raman spectra of exfoliated monolayer

Intertwining of Frustration with Magneto-Elastic Coupling in the Multiferroic LuMnO 3

December 25, 2013
Author(s)
Shin-ichiro Yano, Despina Louca, Songxue Chi, Masaaki Matsuda, Yiming Qiu, John R. Copley, Sang-Wook Cheong
Residual magnetic frustration in the multiferroic LuMNO 3 may be key towards understanding magneto-elastic coupling in hexagonal manganites. Critical magnetic scattering present well above the magnetic ordering temperature Τ N persists below, as observed

Statistical Sampling of Carbon Nanotube Populations by Thermogravimetric Analysis

December 25, 2013
Author(s)
Elisabeth Mansfield, Aparna Kar, Chih-Ming Wang, Ann C. Chiaramonti Debay
Carbon nanotubes are one of the most promising nanomaterials on the market, with applications in electronics devices, sensing, batteries, composites and medical communities. Strict control of the carbon nanotube chemistry and properties is necessary as the

Developmental validation of the PowerPlex 21 System.

December 24, 2013
Author(s)
Carolyn R. Steffen, Martin G. Ensenberger, Robert S. McLaren, Cynthia J. Sprecher, Douglas R. Storts
The PowerPlex(®) 21 System is a STR multiplex that has been optimized for casework samples while still being capable of database workflows including direct amplification. The loci included in the multiplex offer increasing overlap with core loci used in

Fatigue crack growth rates of API X70 pipeline steel in a pressurized hydrogen gas environment

December 21, 2013
Author(s)
Elizabeth S. Drexler, Andrew J. Slifka, Robert L. Amaro, Nicholas Barbosa, Damian S. Lauria, Louis E. Hayden, Douglas G. Stalheim
Hydrogen is known to have a deleterious effect on metal, but pipelines will still be the most cost- effective means of transporting hydrogen gas and sour gas. Rather, it is the codes and standards, such as ASME B31.12, that will guide the design of

A Simulated Sensor-based Approach for Kit Building Applications

December 20, 2013
Author(s)
Zeid Kootbally, Craig I. Schlenoff, Theodore J. Weisman, Stephen B. Balakirsky, Thomas R. Kramer, Anthony Pietromartire
Kit building or kitting is a process in which individually separate but related items are grouped, packaged, and supplied together as one unit (kit). This paper describes advances in developing sensing/control and parts detection technologies enabling

Thermodynamic modelling of liquids: CALPHAD approaches and contributions from statistical physics

December 20, 2013
Author(s)
Chandler A. Becker, J Agren, Marcello Baricco, Qing Chen, Sergei A. Decterov, Ursula R. Kattner, John Perepezko, Gernot Pottlacher, Malin Selleby
Here we describe current approaches to modelling liquids in CALPHAD. available experimental methods and results, and considerations in the use of molecular simulation and first-principles methods in thermodynamic modelling of liquids. We examine the two

Current-induced torques and interfacial spin-orbit coupling

December 19, 2013
Author(s)
Kyung-Jin Lee, H.-W. Lee, Aurelien Manchon, Mark D. Stiles, Paul M. Haney
In bilayer systems consisting of an ultrathin ferromagnetic layer adjacent to a metal with strong spin-orbit coupling, an applied in-plane current induces torques on the magnetization. The torques that arise from spin-orbit coupling are of particular

Dissipative production of a maximally entangled steady state of two quantum bits

December 19, 2013
Author(s)
John P. Gaebler, Yiheng Lin, Florentin Reiter, Ting Rei Tan, Ryan S. Bowler, Anders Sorensen, Dietrich G. Leibfried, David J. Wineland
Entangled states are a key resource in fundamental quantum physics, quantum cryptography, and quantum computation [1]. To date, controlled unitary interactions applied to a quantum system, so-called "quantum gates'', have been the most widely used method

Microscopic investigation of Single-Wall Carbon Nanotube Uptake by Daphnia magna

December 18, 2013
Author(s)
Aaron Edgington, Elijah Petersen, Andrew Herzing, Apparao Rao, Stephen Klaine
The objectives of this study were to determine the absorption of single-wall carbon nanotubes (SWCNTs) across the gut epithelial cells in Daphnia magna and to determine if absorption was influenced by their surface functionalization. This project utilized

Picometer Metrology for Precise Measurement of Refractive Index, Pressure, and Temperature

December 18, 2013
Author(s)
Jack A. Stone Jr., Patrick F. Egan, Donavon Gerty, Jay H. Hendricks, Douglas A. Olson, Jacob E. Ricker, Gregory E. Scace, Gregory F. Strouse
Fabry-Perot interferometers can be used for very precise measurement of the refractive index of gasses. This can enable increased accuracy of interferometer-based length measurement. In addition, because the refractive index of a gas depends on its

Review of alternative cooling technologies

December 18, 2013
Author(s)
S J. Brown, Piotr A. Domanski
This paper considers the alternative cooling technologies studied by Fisher et al. (1994) and assesses their current performance and market potential in reference to vapor compression technology. First, a taxonomy of cooling technologies based on the main
