Traceable Dynamic Calibration of Force Transducers by Primary Means

July 8, 2016
Author(s)
Nicholas Vlajic, Akobuije Chijioke
We describe an apparatus for traceable, dynamic calibration of force transducers using harmonic excitation, and report calibration measurements of force transducers using this apparatus. In the apparatus, the force applied to the transducer is produced by

Adsorption of Two Gas Molecules at a Single Metal Site in a Metal-Organic Framework

July 7, 2016
Author(s)
Tomce Runcevski, Matthew T. Kapelewski, Rodolfo M. Torres-Gavosto, Jacob Daniel Tarver, Craig Brown, Jeffrey R. Long
One strategy to markedly increase the gas storage capacity of metal-organic frameworks, is to introduce coordinatively-unsaturated metal centers capable of binding multiple gas molecules. Herein, we provide an initial demonstration that a single mental

Advancing X-Ray Scattering Metrology Using Inverse Genetic Algorithms

July 7, 2016
Author(s)
Adam F. Hannon, Daniel F. Sunday, Donald A. Windover, Regis J. Kline
We compare the speed and effectiveness of two genetic optimization algorithms to the results of statistical sampling via a Markov Chain Monte Carlo algorithm to find which is the most robust method for determining real space structure in periodic gratings

Design of 280 GHz feedhorn-coupled TES arrays for the balloon-borne polarimeter SPIDER

July 7, 2016
Author(s)
Johannes Hubmayr, Jason E. Austermann, James A. Beall, Daniel T. Becker, Shannon M. Duff, Arpi L. Grigorian, Gene C. Hilton, Joel N. Ullom, Michael R. Vissers
We describe 280 GHz bolometric detector arrays that instrument the balloon-borne polarimeter spider. A primary science goal of spider is to measure large-scale B-mode polarization of the cosmic microwave back-ground (cmb) in search of the cosmic-inflation

Dynamic Signature of Molecular Association in Methanol

July 7, 2016
Author(s)
Christopher E. Bertrand, Jeffrey L. Self, John R. Copley, Antonio Faraone
Quasielastic neutron scattering measurements and molecular dynamics simulations were combined to investigate the collective dynamics of deuterated methanol. A slow, non-Fickian mode was observed in addition to the standard heat mode. The qualitative

Influence of Hydrocarbon Moiety of DMMP on Flame Propagation in Lean Mixtures

July 7, 2016
Author(s)
Gregory T. Linteris, Valeri I. Babushok, Viswanath R. Katta, Fumiaki Takahashi
Phosphorus-containing compounds (PCCs) have been found to be significantly more effective than CF3Br for reducing burning velocity when added to stoichiometric hydrocarbon-air flames. However, when added to lean flames, DMMP (dimethylmethylphosphonate) is

Interconversion of Peptide Mass Spectral Libraries Derivatized with iTRAQ or TMT Labels

July 7, 2016
Author(s)
Zheng Zhang, Xiaoyu Yang, Yuri A. Mirokhin, Dmitrii V. Tchekhovskoi, Weihua Ji, Sanford P. Markey, Pedatsur Neta, Bowen A. Michael, Stephen E. Stein
Derivatizing peptides with isobaric tags such as iTRAQ and TMT is widely employed in proteomics due to their ability to multiplex quantitative measurements. We recently made publicly available a large peptide library derived from iTRAQ 4-plex labeled

Local coexistence of VO2 phases revealed by deep data analysis

July 7, 2016
Author(s)
Evgheni Strelcov, Anton Ievlev, Alex Belianinov, Alexander Tselev, Andrei A. Kolmakov, Sergei Kalinin
We report a synergistic approach of micro-Raman spectroscopic mapping and deep data analysis to study the distribution of crystallographic phases and ferroelastic domains in a defected Al-doped VO2 microcrystal. Bayesian linear unmixing revealed an uneven

An Informatics Infrastructure for the Materials Genome Initiative

July 6, 2016
Author(s)
Alden A. Dima, Sunil K. Bhaskarla, Chandler A. Becker, Mary C. Brady, Carelyn E. Campbell, Philippe J. Dessauw, Robert J. Hanisch, Ursula R. Kattner, Kenneth G. Kroenlein, Adele P. Peskin, Raymond L. Plante, Guillaume Sousa Amaral, Zachary T. Trautt, James A. Warren, Sharief S. Youssef, Sheng Yen Li, Pierre Francois Rigodiat, Marcus W. Newrock
A materials data infrastructure that enables the sharing and transformation of a wide range of materials data is an essential part of achieving the goals of the Materials Genome Initiative. We describe two high-level requirements of such an infrastructure
