Energy Price Indices and Discount Factors for Life-Cycle Cost Analysis - 2013

July 15, 2013
Author(s)
Amy S. Rushing, Joshua D. Kneifel, Barbara C. Lippiatt
This is the 2013 edition of energy price indices and discount factors for performing life-cycle cost analyses of energy and water conservation and renewable energy projects in federal facilities. It will be effective from April 1, 2013 to March 31, 2014

ITL Issues Guidelines for Managing the Security of Mobile Devices

July 15, 2013
Author(s)
Elizabeth B. Lennon
This ITL Bulletin announces the publication of NIST Special Publication 800-124 Revision 1, Guidelines for Managing the Security of Movile Devices in the Enterprise. The revised guidelines will assist organizations in managing the security of mobile

Method for Measuring Axis Orthogonality in MEMS Accelerometers

July 15, 2013
Author(s)
Craig D. McGray, Muhammad Y. Afridi, Jon C. Geist
A method is described for the computation of axis orthogonality errors in 3-axis accelerometers, based on the application of gravitational force at known angles. A precision two-axis articulated gimbal system is used to control the angle at which the

Microfluidic Platform for Magnetic Nanoparticle Trapping and Detection

July 15, 2013
Author(s)
Charles A. Little, John Pellegrino, Stephen E. Russek
We evaluate giant magnetoresistance (GMR) sensors to trap and count small concentrations of magnetic nanoparticles (MNPs) within microfluidic flow. The device presented in this paper takes the novel approach of capturing and detecting MNPs utilizing the

Mode reconstruction of a light field by multi-photon statistics

July 15, 2013
Author(s)
Elizabeth A. Goldschmidt, Fabrizio Piacentini, I. Ruo Berchera, Sergey V. Polyakov, Silke Peters, Stefan Kuck, Giorgio Brida, Ivo P. Degiovanni, Alan L. Migdall, Marco Genovese
Knowing the underlying number and structure of occupied modes of a light field plays a crucial role in minimizing loss and decoherence of quantum information. Typically, full characterization of the mode structure involves a series of several separate

Multicomponent Chemical Imaging of Pharmaceutical Solid Dosage Forms with Broadband CARS Microscopy

July 15, 2013
Author(s)
Christopher M. Hartshorn, Marcus T. Cicerone, Young J. Lee, Charles H. Camp, John M. Heddleston, Patrick Marsac, Tim Rhodes, Zhen Liu, Nicole Canfield
We compare broadband coherent anti-Stokes Raman scattering (BCARS) microscopy with spontaneous Raman microscopy for quantitative and qualitative assessment of multicomponent pharmaceuticals. Indomethacin was used as a model active pharmaceutical ingredient

Preparation of Non-equilibrium Nuclear Spin States in Double Quantum Dots

July 15, 2013
Author(s)
Jacob M. Taylor, Michael Gullans, Jacob J. Krich, Bertrand I. Halperin, M D. Lukin
We theoretically study the dynamic polarization of lattice nuclear spins in GaAs double quantum dots containing two electrons. We introduce a semiclassical model that allows to explore a wide range of parameter regimes in this system. We identify three

Use of Half Metallic Heusler Alloys in CoFeB/MgO/Heusler Alloy Tunnel Junctions

July 15, 2013
Author(s)
Andrew P. Chen, Gen G. Feng, Robert D. Shull
Heusler Alloys Co(sub2)FeSi and Co(sub2)MnSi were deposited on both single crystal MgO (100) and polycrystalline SiO(Sub2) silicon thermal oxide substrates and characterized by x-ray diffraction before and after thermal annealing at various temperatures

Picometer metrology for precise measurement of refractive index, pressure, and temperature

July 14, 2013
Author(s)
Jack A. Stone Jr., Patrick F. Egan, Jay H. Hendricks, Gregory F. Strouse, Douglas A. Olson, Jacob E. Ricker, Gregory E. Scace
For several years we have been studying the use of Fabry-Perot interferometers for precise measurement of the refractive index of gasses, where the primary motivation has been to improve interferometer-based length measurement. Because the refractive index

THE EFFECT OF MICROSTRUCTURE ON THE HYDROGEN-ASSISTED FATIGUE OF PIPELINE STEELS

July 14, 2013
Author(s)
Andrew J. Slifka, Elizabeth S. Drexler, Robert L. Amaro, Damian S. Lauria, April Stevenson, Douglas G. Stalheim, Louis E. Hayden
Tests on the fatigue crack growth rate were conducted on four pipeline steels, two of grade API 5L- X52 and two API 5L-X70. One X52 material was from the mid 1960s and the other was manufactured in 2011. The two X70 materials had a similar vintage and

Thermoelectric imaging of structural disorder in epitaxial graphene

July 14, 2013
Author(s)
Sanghee Cho, Stephen D. Kang, Wondong Kim, Eui-Sup Lee, Sung-Jae Woo, Ki-Jeong Kong, Ilyou Kim, Hyeong-Do Kim, Tong Zhang, Joseph A. Stroscio, Yong-Hyun Kim, Ho-Ki Lyeo
Many structural defects and strain fields develop during the preparation of thin films and nanostructures, with their origins being at the atomic level1,2. Sensitively detecting these subtle features with high sensitivity and resolution, and their
