Acceleration and Parallelization of ZENO/Walk-on-Spheres

June 1, 2016
Author(s)
Derek Juba, Walid Keyrouz, Michael V. Mascagni, Mary C. Brady, Michael Mascagni
This paper describes our on-going work to accelerate ZENO, a software tool based on Monte Carlo methods (MCMs), used for computing material properties at the nanoscale. ZENO employs three main algorithms: (1)Walk on Spheres (WoS), (2)interior sampling, and

An Improved Method Of Modeling Infiltration In Commercial Building Energy Models

June 1, 2016
Author(s)
Lisa C. Ng, Steven J. Emmerich, Andrew K. Persily
Different strategies for improving building envelope thermal performance are being implemented in commercial building design and construction as well as being incorporated into ASHRAE standards and other design requirements. The energy impacts of

Capacitive Displacement Sensor for Detecting Planar Submicrometer Motion

June 1, 2016
Author(s)
Svetlana Avramov-Zamurovic1, Jae M. Yoo, Nicholas Dagalakis
This paper describes the design of a very simple displacement sensor that measures the displacement of an object by measuring the change in capacitance due to the movement of this object in the sensor fringing electric field. Two sensor geometries with

Energetic Electrons Driven in the Polarization Direction of an Intense Laser Beam Incident Normal to a Solid Target

June 1, 2016
Author(s)
Lawrence T. Hudson, John F. Seely, Nino R. Pereira, H. Chen, G.J. Williams, R.P. Drake, C.C. Kuranz, C.A. Di Stefano, J. Park
Experiments were performed at the LLNL Titan laser to measure the propagation direction of the energetic electrons that were generated during the interaction of the polarized laser beam with solid targets in the case of normal incidence. The energetic

In Situ Structural Characterization of Ageing Kinetics in Aluminum Alloy 2024 across Angstrom-to-Micrometer Length Scales

June 1, 2016
Author(s)
Fan Zhang, Lyle E. Levine, Andrew J. Allen, Carelyn E. Campbell, Adam Abel Creuziger, Nataliya Kazantseva, Jan Ilavsky
The precipitate structure and precipitation kinetics in an Al-Cu-Mg alloy (AA2024) aged at 190 °C, 208 °C, and 226 °C have been studied using ex situ TEM and in situ synchrotron-based, combined ultra-small angle X-ray scattering, small angle X-ray

LABORATORY FILTER MEDIA

June 1, 2016
Author(s)
Thomas J. Bruno
Filtration is the physical separation of a component or components (which may be solid, liquid, gel, etc.) from a matrix stream (which is usually a fluid), without causing any other changes such as chemical reactions. In the laboratory, filtration is most

Premixed flame inhibition by CF3Br and C3H2F3Br (2-BTP)

June 1, 2016
Author(s)
John Pagliaro, Gregory T. Linteris, Nicolas Bouvet
The un-stretched burning velocities and Markstein lengths of premixed CH4- and C3H8-air flames with added C3H2F3Br (2-BTP) or CF3Br (Halon 1301), have been studied experimentally and numerically. The predicted un-stretched burning velocities, using a

Removing divergence of JCGM documents from the GUM (1993)

June 1, 2016
Author(s)
Raghu N. Kacker
The stated mission of the Joint Committee for Guides in Metrology (JCGM) is to maintain and promote the use of the Guide to the Expression of Uncertainty in Measurement (GUM) and the International Vocabulary of Metrology (VIM, 2nd edition). The JCGM has

Strategies for Achieving Measurement Assurance for Cell Therapy Products

June 1, 2016
Author(s)
Carl G. Simon Jr., Anne L. Plant, Sumona Sarkar, John T. Elliott, Sheng Lin-Gibson
Cell therapy products (CTPs) need quantitative, validated, and robust assays to support informed decision making during their development, manufacturing, and regulation. These products, the materials involved in their production and the methods for

Ultra-Small-Angle Neutron Scattering with Azimuthal Asymmetry

June 1, 2016
Author(s)
X. Gu, David F. Mildner
Small-angle neutron scattering (SANS) measurements from thin rock samples such as shales demand as great a scattering vector range as possible because the pores cover a wide range of sizes. The limitation of the scattering vector range for pinhole SANS

Minority-carrier dynamics in semiconductors probed by two-photon microscopy

May 31, 2016
Author(s)
Benoit H. Gaury, Paul M. Haney
Two-photon time-resolved photoluminescence has been recently applied to various semiconductor devices to determine carrier lifetime and surface recombination velocities. So far the theoretical modeling activity has been mainly limited to the commonly used

MPInterfaces: A Materials Project based Python Tool for a High Throughput Computational Screening of Interfacial Systems

May 31, 2016
Author(s)
Arunima Singh, Kiran Mathew, Joshua Grabriel, Kamal Choudhary, Susan B. Sinnott, Albert Davydov, Francesca M. Tavazza, Richard G. Hennig
A Materials Project based open-source python tool, MPInterfaces, has been developed to automate the high throughput computational screening and study of interfacial systems. The framework encompasses creation and manipulation of interface structures for
