Fast Formation of Low-Defect-Density Tethered Bilayers by Fusion of Multilamellar Vesicles

January 10, 2017
Author(s)
Tadas Ragaliauskas, Mindaugas Mickevicius, Bozena Rakovska, Tadas Penkauskas, Frank Heinrich, Gintaras Valincius
Multilamelar vesicles fuse to molecular-anchor-grafted surfaces yielding low defect density, tethered bilayer membranes. Continuous bilayers are formed within 10 min, while the electrically insulating bilayers with less than 0,1 υmu-1} defect density can

Gapped Excitation in Dense Kondo Lattice CePtZn

January 10, 2017
Author(s)
Leland Weldon Harriger, Steven M.T. Disseler, J. Gunasekera, Jose A. Rodriguez, J. Pixley, P. Manfrinetti, S. K. Dhar, D. K. Singh
We report on neutron υSR scattering studies of dense Kondo lattice CePtZn. The system develops long range incommensurate magnetic order as the temperature is reduced below T N = 1.75 K. Interesting, a Q-indpenedent characteristic and its persistence to

LipidPioneer: Comprehensive User-Generated Exact Mass Templates for Lipidomics

January 10, 2017
Author(s)
Candice Z. Ulmer, John Bowden, Jared M. Ragland, Timothy J. Garrett, Jeremy P. Koelmel
Lipidomics, the comprehensive measurement of lipid species in a biological system, has promising potential in biomarker discovery and elucidating disease etiology. Advances in separation, mass spectrometric techniques, and applications to novel substrates

Retention behavior of alkyl-substituted polycyclic aromatic sulfur heterocycle isomers in gas chromatography on stationary phases of different selectivity

January 10, 2017
Author(s)
Walter B. Wilson, Lane C. Sander, Jorge O. Ona Ruales, Stephanie Mossner, Leonard M. Sidisky, Milton Lee, Stephen A. Wise
Retention indices for 10 sets of alkyl-substituted polycyclic aromatic sulfur heterocycles (PASHs) isomers (total of 80 PASHs) were determined using gas chromatography with three different stationary phases: a 50% phenyl phase, a 50% liquid crystalline

Retention behavior of isomeric polycyclic aromatic sulfur heterocycles in gas chromatography on stationary phases of different selectivity

January 10, 2017
Author(s)
Walter B. Wilson, Lane C. Sander, Jorge O. Ona Ruales, Leonard M. Sidisky, Milton Lee, Stephen A. Wise
Retention indices for 70 polycyclic aromatic sulfur heterocycles (PASHs) were determined using gas chromatography with three different stationary phases: a 50% phenyl phase, a 50% liquid crystalline dimethylpolysiloxane (LC-DMPS) phase, and an ionic liquid

Coherent UV-to-Visible Light Arrays

January 9, 2017
Author(s)
Dong Yoon Oh, Scott Diddams, Ki Youl Yang, Kerry J. Vahala, Connor Fredrick, Gabriel Ycas
Short duration, intense pulses of light can experience dramatic spectral broadening when propagating through lengths of optical fiber. This continuum generation process is caused by a combination of nonlinear optical effects including the formation of so

Origins and Demonstrations of Electrons with Orbital Angular Momentum

January 9, 2017
Author(s)
Benjamin McMorran, Amit Agrawal, Peter Ercius, Vincenzo Grillo, Andrew Herzing, Tyler R. Harvey, Martin Linck
The surprising message of the 1992 paper of Allen, Beijersbergen, Spreeuw, and Woerdman (ABSW) was that photons could exhibit orbital motion in free space, which subsequently launched advancements in optical manipulation, microscopy, quantum optics

Preflight Radiometric Calibration of Orbiting Carbon Observatory 2

January 9, 2017
Author(s)
Stephen Maxwell, B. Carol Johnson, Robert Rosenberg, Lars Chapsky, Richard A. Lee, Randy Pollock
This paper describes the prelaunch radiometric calibration of the imaging spectrometers used on the second Orbiting Carbon Observatory (OCO-2). The gain and dark response were characterized for each focal plane array detector element. An integrating sphere

ASCE/SEI 41 Predicted Performance of Newly Designed BRBFs

January 8, 2017
Author(s)
Matthew Speicher, John Harris
Structural engineers in the United States have turned to performance-based design methodologies for design of new buildings in order to find improved design solutions as compared to those obtained using prescriptive design provisions of current model

EVALUATION OF STRUCTURAL PERFORMANCE BASED ON AN ENERGY BALANCE APPROACH

January 8, 2017
Author(s)
Kevin K F Wong, Steven McCabe
An analytical method is developed to investigate the potential energy of fully nonlinear framed structures and other energy characteristics due to earthquake ground motions. Since the potential energy relates to the stiffness of the structure, it consists

Impact of timing on the Proximity Services (ProSe) synchronization function

January 8, 2017
Author(s)
Samantha Gamboa Quintiliani, Fernando Cintron, David W. Griffith, Richard A. Rouil
Long Term Evolution Advanced (LTE-A) introduces a new feature called Proximity Services (ProSe), which enables device-to-device (D2D) communication between User Equipment (UE) and the capability to operate out-of-network. In order to establish a D2D

Data Resources for Thermophysical Properties of Metals and Alloys, Part 1: Structured Data Capture from the Archival Literature

January 7, 2017
Author(s)
Boris Wilthan, Erik A. Pfeif, Vladimir Diky, Robert D. Chirico, Ursula R. Kattner, Kenneth G. Kroenlein
In support of the continuous scientific and industrial need for accessible and high-quality thermophysical property data for metals and alloy systems, NIST/TRC is expanding its data archiving and critical evaluation activities to include this area. As part

An Introduction to Privacy Engineering and Risk Management in Federal Information Systems

January 5, 2017
Author(s)
Sean W. Brooks, Michael E. Garcia, Naomi B. Lefkovitz, Suzanne Lightman, Ellen M. Nadeau
This document provides an introduction to the concepts of privacy engineering and risk management for federal information systems. These concepts establish the basis for a common vocabulary to facilitate better understanding and communication of privacy

Limestone and Silica Powder Replacements for Cement: Early-Age Performance

January 5, 2017
Author(s)
Dale P. Bentz, Chiara F. Ferraris, Scott Z. Jones, Didier Lootens, Franco Zunino
Developing functional concrete mixtures with less ordinary portland cement (OPC) has been one of the key objectives of the 21st century sustainability movement. While the supply of many alternatives to OPC (such as fly ash or slag) may be limited, those of
