Molecular-Based Virial Coefficients of CO2-H2O Mixtures

August 7, 2015
Author(s)
Allan H. Harvey, Andrew J. Schultz, David A. Kofke
We report values of the second and third virial coefficients for the system CO2-H2O, calculated as a function of temperature via numerical evaluation of cluster integrals that define the coefficients in terms of the intermolecular potential energy

Representation and Validation of Liquid Densities for Pure Compounds and Mixtures

August 7, 2015
Author(s)
Vladimir Diky, John P. O'Connell, Jens Abildskov, Kenneth G. Kroenlein, Michael D. Frenkel
Reliable correlation and prediction of liquid densities are important for designing chemical processes at normal and elevated pressures. We have extended a corresponding states model from molecular theory to yield a robust method for quality testing of

Small Molecule Inhibitors of 8-Oxoguanine DNA Glycosylase-1 (OGG1)

August 7, 2015
Author(s)
Pawel Jaruga, Erdem Coskun, M Miral Dizdar, Nathan Donley, Stephen Lloyd, Amanda McCullough
ABSTRACT The DNA base excision repair (BER) pathway, which utilizes DNA glycosylases to initiate repair of specific DNA lesions, is the major pathway for the repair of DNA damage induced by oxidation, alkylation, and deamination. Early results from

Stabilization of Cubic Sr 2 FeMoO 6 through Topochemical Reduction

August 7, 2015
Author(s)
Daniel D. Taylor, Nathaniel J. Schreiber, Craig Brown, Angel M. Arevalo-Lopez, Efrain E. Rodriguez
Sr 2FeMoO 6 has been extensively studied for application in spintronic devices. Through the topochemical deintercalation of the oxygen anions, the high temperature cubic phase can be stabilized at room temperature while leaving the magnetic ordering intact

Dew-point Measurements For Water In Compressed Carbon Dioxide

August 6, 2015
Author(s)
Christopher W. Meyer, Allan H. Harvey
When transporting CO2 for sequestration, it is important to know the water dew point in order to avoid condensation that can lead to corrosion. We have constructed a flow apparatus to measure the water content at saturation in a compressed gas. A saturator

On Effectiveness of Smart Grid Applications using Co-simulation

August 6, 2015
Author(s)
Paul Moulema, Wei Yu, David W. Griffith, Nada T. Golmie
The smart grid is a complex system that comprises components from both the power grid and communication networks. To understand the behavior of such a complex system, co-simulation is a viable tool to capture the interaction and the reciprocal effects

Quasiparticle recombination in hotspots in superconducting current-carrying nanowires

August 6, 2015
Author(s)
Alex Kozorezov, Colin Lambert, Francesco Marsili, Martin Stevens, Varun Verma, Jeffrey A. Stern, Rob Horansky, Shellee D. Dyer, Shannon Duff, David P. Pappas, Adriana Lita, Matthew D. Shaw, Richard Mirin, Sae Woo Nam
We describe a kinetic model of recombination of nonequilibrium quasiparticles generated by single photon absorption in superconducting current-carrying nanowires. The model is developed to interpret two-photon detection experiments in which a single photon

Formation of Strain Induced Quantum Dots in Gated Semiconductor Nanostructures

August 5, 2015
Author(s)
Ted C. Thorbeck, Neil M. Zimmerman
Elastic strain changes the energies of the conduction and valence bands in a semiconductor, which will affect transport through a semiconductor nanostructure. We show that the typical strains in a semiconductor nanostructure arising from metal gates or

Photovoltaic switching mechanism in lateral structure hybrid Perovskite solar cells

August 5, 2015
Author(s)
Yongbo Yuan, Jungseok Chae, Yuchuan Shao, Qi Wang, Zhengguo Xiao, Andrea Centrone, Jinsong Huang
Organometal trihalide perovskite solar cells with lateral device architecture recently attracted interest because of their switchable photovoltaic effect, which potentially could be leveraged to realize transparent-electrode-free solar cells. However, the

Results of barrier fabrics tested in an inverted configuration

August 5, 2015
Author(s)
Rick D. Davis, Shonali Nazare, Szabolcs Matko, William M. Pitts, Mauro Zammarano
The document will be used to facilitate discussions between California Bureau of Electronics and Appliance Repair, Home Furnishings, and Thermal Insulation (CBEARHFTI) and us (Fire Research Division (FRD) at the National Institute of Standards and

Sapphire as an ideal substrate and a dielectric layer for n-layer MoS2 thin films

August 5, 2015
Author(s)
Arunima Singh, Francesca M. Tavazza, Albert Davydov, Richard G. Hennig
Sapphire (α-Al2O3) is a common substrate for the growth of single- to few-layer MoS2 films, and as a high-κ dielectric gate oxide for 2D-MoS2 based transistors. Using density-functional theory calculations with a van der Waals functional we investigate the

Constructive Relationships Between Algebraic Thickness and Normality

August 4, 2015
Author(s)
Joan Boyar, Magnus G. Find
We study the relationship between two measures of Boolean functions; "algebraic thickness" and "normality". For a function f, the algebraic thickness is a variant of the "sparsity", the number of nonzero coefficients in the unique F_2 polynomial

Effects of Password Permutation on Subjective Usability Across Platforms

August 4, 2015
Author(s)
Kristen Greene
The current work examines subjective password usability across platforms—desktop, smartphone, and tablet—using system- generated passwords that adhere to the stricter password requirements found in higher-security enterprise environments. This research

Isotopic Labeling of Proteins in Halobacterium salinarum

August 4, 2015
Author(s)
Thomas E. Cleveland, Zvi Kelman
It is often necessary to obtain isotopically labeled proteins containing 15N, 13C or 2H for NMR; and 2H for small-angle neutron scattering (SANS) or neutron diffraction studies. To achieve uniform isotopic labeling, protein expression is most commonly

On-Chip Silicon Waveguide Bragg Grating Photonic Temperature Sensor

August 4, 2015
Author(s)
Nikolai Klimov, Sunil Mittal, Zeeshan Ahmed, Michaela Berger
Resistance thermometry is a time-tested method for temperature measurements. Fundamental limits to resistance-based approaches, spurred our interest in developing photonic temperature sensors as a viable alternative. In this study we demonstrate that our

Secure Hash Standard

August 4, 2015
Author(s)
National Institute of Standards and Technology (NIST), Quynh Dang
This standard specifies hash algorithms that can be used to generate digests of messages. The digests are used to detect whether messages have been changed since the digests were generated. The Applicability Clause of this standard was revised to

SHA-3 Standard: Permutation-Based Hash and Extendable-Output Functions

August 4, 2015
Author(s)
National Institute of Standards and Technology (NIST), Morris J. Dworkin
This Standard specifies the Secure Hash Algorithm-3 (SHA-3) family of functions on binary data. Each of the SHA-3 functions is based on an instance of the KECCAK algorithm that NIST selected as the winner of the SHA-3 Cryptographic Hash Algorithm
