Carbon Capture and Storage Properties of Porous Octahedral Molecular Sieve

March 7, 2019
Author(s)
Matthew Lawson, Jarod C. Horn, Winnie Wong-Ng, Laura Espinal, Huong Giang Nguyen, James A. Kaduk, Saul H. Lapidus, Yongtao Meng, Steven L. Suib, Lan Li
Based on the experimentally determined framework structure of porous MnO2 octahedral molecular sieve (OMS)-5, we used density functional theory-based calculations to evaluate the effect of Na+ cation on pore dimensionality and structural stability, and the

Cyber-Physical Systems and Internet of Things

March 7, 2019
Author(s)
Christopher Greer, Martin J. Burns, David Wollman, Edward Griffor
This NIST Special Publication describes the relationship between the phrases "cyber-physical systems" and "Internet of Things." CPS and IoT both refer to trends in integrating digital capabilities, including network connectivity, with physical devices and

Domain-wall motion and interfacial Dzyaloshinskii-Moriya interactions in Pt/Co/Ir(tIr)/Ta multilayers

March 7, 2019
Author(s)
Kowsar Shahbazi, Joo-Von Kim, Hans Nembach, Justin Shaw, Andreas Bischof, Marta Rossell, Vincent Jeudy, Thomas A. Moore, Christopher H. Marrows
The interfacial Dzyaloshinskii-Moriya interaction (DMI) is important for chiral domain walls (DWs) and for stabilizing magnetic skyrmions. We study the effects of introducing increasing thicknesses of Ir, from zero to 2 nm, into a Pt/Co/Ta multilayer

Hydrogen Isotope Effect in Embrittlement and Fatigue Crack Growth of Steel

March 7, 2019
Author(s)
Matthew J. Connolly, Andrew J. Slifka, Robert L. Amaro, Elizabeth S. Drexler, May L. Martin
The corrosive effect of hydrogen on steel is a long-standing problem. Corrosion in the presence of hydrogen is, in part, a consequence of the fast diffusion of hydrogen in ferritic steels. Because of the identical chemical properties but large differences

Lipidomics for wildlife disease etiology and biomarker discovery: a case study of pansteatitis outbreak in South Africa

March 5, 2019
Author(s)
John Bowden, Jeremy P. Koelmel, Candice Z. Ulmer, Susan Fogelson, Hannes Botha, Christina M. Jones, Jackie T. Bangma, Theresa M. Cantu, Matthew P. Guillette, Wilmien Luus-Powell, Joseph Sara, Willem J. Smit, Korin Albert, Harmony Miller, Berkley Olsen, Jason A. Cochran, Timothy J. Garrett, Richard A. Yost
Lipidomics is a promising tool to determine biomarkers and elucidate mechanisms associated with anthropogenic-induced stress in wildlife. Therefore, we examine the application of lipidomics for in situ studies on Mozambique tilapia (Oreochromis mossambicus

Measurement Uncertainty of the Air System in the IBAL

March 5, 2019
Author(s)
Amanda J. Pertzborn
The Intelligent Building Agents Laboratory (IBAL) has been designed and constructed to demonstrate the potential for distributed, intelligent software agents to perform optimization of control systems in commercial buildings. This technical note presents

Methanol Accelerates DMPC Flip-Flop and Transfer: A SANS Study on Lipid Dynamics

March 5, 2019
Author(s)
Michael H. L. Nguyen, Mitchell DiPasquale, Brett W. Rickeard, Christopher B. Stanley, Elizabeth Kelley, Drew Marquardt
Methanol is a common solubilizing agent used for the study of transmembrane proteins/peptides in biological and synthetic membranes. Using small angle neutron scattering (SANS) and a strategic contrast matching scheme, we show that methanol has a unique

Channel Characterization and Delay Optimization for Industrial Wireless Control Systems

March 4, 2019
Author(s)
Xiaolin Jiang, Zhibo Pang, Rick Candell, Dacfey Dzung, Michele Luvisotto, Carlo Fischione
Wireless communication is gaining popularity in industry for its simple deployment, mobility and low cost. Ultra low latency and high reliability requirements of mission critical industrial applications are highly demanding for wireless communication, and

COMPOSITION DETERMINATION OF LOW-PRESSURE GAS-PHASE MIXTURES BY 1H NMR SPECTROSCOPY

March 4, 2019
Author(s)
Chris Suiter, Mark O. McLinden, Thomas J. Bruno, Jason A. Widegren
1H NMR spectroscopy was used to analyze vapor-phase mixtures of methane and propane at low to moderate pressures. The mixtures were prepared gravimetrically and had low uncertainty in their composition. The primary mixture used for this work had a methane

Exploring Interfacial Exchange Coupling and Sublattice Effect in Heavy Metal/Ferrimagnetic Insulator Heterostructures using Hall Measurements, X-Ray Magnetic Circular Dichroism, and Neutron Reflectometry

March 4, 2019
Author(s)
Qiming Shao, Alexander Grutter, Yawen Liu, Guoqiang Yu, Chao-Yao Yang, Dustin A. Gilbert, Elke Arenholz, Padraic Shafer, Xiaoyu Chi, Chi Tang, Mohammed Aldosary, Aryan Navabi, Qing Lin He, Brian Kirby, Jing Shi, Kang L. Wang
Ferrimagnetic insulators (FMIs), such as rare-earth iron garnets, are of considerable interest for low-power spintronics due to low Gilbert damping and the absence of free charge carriers. FMIs are also promising candidate materials for high-frequency

Structural basis of CO2 adsorption in a flexible metal organic framework material

March 4, 2019
Author(s)
Andrew J. Allen, Winnie K. Wong-Ng, Eric J. Cockayne, Jeffrey T. Culp, Christopher Matranga
This paper reports the structural basis of CO2 adsorption in a representative model flexible metal organic framework (MOF) material, Ni(1,2-bis(4-pyridyl)ethylene)[Ni(CN)4] (NiBpene or PICNIC-60). NiBpene exhibits a CO2 sorption isotherm with

Use of Transition Models to Design High Performance TESs for the LCLS-II Soft X-Ray Spectrometer

March 4, 2019

Kelsey M. Morgan, Daniel T. Becker, Douglas A. Bennett, William B. Doriese, Johnathon D. Gard, K D. Irwin, Sang-Jun Lee, Dale Li, John A. Mates, Christine G. Pappas, Daniel R. Schmidt, Charles Titus, Daniel Van Winkle, Joel N. Ullom, Abigail L. Wessels, Daniel S. Swetz
We are designing an array of transition-edge sensor (TES) microcalorimeters for a soft X-ray spectrometer at the Linac Coherent Light Source at SLAC National Accelerator Laboratory to coincide with upgrades to the free electron laser facility. The complete

Improved Calculation Method for Insulation-based Fire Resistance of Composite Slabs
