Investigation of Residential Cooktop Ignition Prevention Technologies

May 31, 2018
Author(s)
Sung Chan Kim, Anthony Hamins, Matthew Bundy
Several international standards and regulations regarding residential cooktop ignition prevention have existed for as long as a decade. A series of cooking experiments were conducted by National Institute of Standards and Technology (NIST) to examine the

Navigating Unmountable Media with the Digital Forensics XML File System

May 31, 2018
Author(s)
Alexander J. Nelson, Alexandra Chassanoff, Alexandra Holloway
Some computer storage is non-navigable by current general-purpose computers. This could be because of obsolete interface software, or a more specialized storage system lacking widespread support. These storage systems may contain artifacts of great

Chen, B Caja, H Yi, A Boury, S Lorcy, M C. Asensio, T Gans, D O?Connell, F Reniers, A Vincze, M Anderle
Nanometer-sized structures, surfaces and sub-surface phenomena have played an enormous role in science and technological applications and represent a driving-force of current interdisciplinary science. Recent developments include the atomic-scale

Resonator Stabilization Architecture to Suppress Switching Transient Crosstalk in I-CDM

May 30, 2018
Author(s)
Malcolm S. Durkin, Joel C. Weber, William B. Doriese, Gene C. Hilton, Daniel S. Swetz, Joel N. Ullom
The ever-increasing sizes of transition-edge sensor (TES) microcalorimeter arrays motivates improved multiplexed readout with large multiplexing factors, low power dissipation, and low levels of crosstalk. Current-summed code division multiplexing (I-CDM)

Bang-bang shortcut to adiabaticity in the Dicke model as realized in a Penning trap experiment

May 29, 2018
Author(s)
J. Cohn, Arghavan Safari-Naini, R. J. Lewis-Swan, Justin G. Bohnet, M. Garttner, Kevin Gilmore, Elena Jordan, Ana Maria Rey, John Bollinger, James K. Freericks
We introduce a bang-bang shortcut to adiabaticity for the Dicke model, which we implement via a two-dimensional array of trapped ions in a Penning trap with a spin-dependent force detuned close to the center-of-mass drumhead mode. Our focus is on employing

Educational commitment and social networking: The power of informal networks

May 29, 2018
Author(s)
Justyna Zwolak, Michael P. Zwolak, Eric Brewe
Prior studies found that the lack of an engaging pedagogy and the highly competitive atmosphere in introductory science courses tend to discourage students from pursuing STEM (science, technology, engineering, and mathematics) majors. Once in a STEM field

Reduction of Short Wavelength Reflectance of Multi-wall Vertically Aligned Carbon Nanotubes Through UV Laser Irradiation

May 29, 2018
Author(s)
Michelle S. Stephens, Brian J. Simonds, Christopher S. Yung, Davis R. Conklin, David J. Livigni, Alberto R. Oliva, John H. Lehman
Multi-wall carbon nanotube coatings are used as broadband, low-reflectance absorbers for bolometric applications, blackbody radiators, and for stray light control. Irradiation of single wall carbon nanotubes with UV laser light has been shown to remove

An Experimental and Computational Study of CO 2 Adsorption in the Sodalite-Type M-BTT (M = Cr, Mn, Fe, Cu) Metal-Organic Frameworks Featuring Open Metal Sites

May 28, 2018
Author(s)
Mehrdad Asgari, Sudi Jawahery, Eric D. Bloch, Matthew R. Hudson, Roxana Flacau, Bess Vlaisavljevich, Jeffrey R. Long, Craig Brown, Wendy L. Queen
We present a comprehensive investigation of the CO 2 adsorption properties of the isostructural series of metal-organic frameworks M-BTT (M =Cr, Mn, Fe, Cu, BTT 3- = 1,3,5-benzenetristetrazolate), which exhibit a high density of open metal sites capable of

What Causes the Anomalous Aggregation in Pluronic Aqueous Solutions?

May 28, 2018
Author(s)
Kuo-Chih Shih, Zhiqiang Shen, Ying Li, Martin Kroger, Shing-Yun Chang, Yun Liu, Mu-Ping Nieh, Hsi-Mei Lai
Pluronic (PL) block copolymers has been widely used as delivery carriers, molecular templates for porous media, process additive of affecting rheological behavior. Unlike most surfactant systems, where unimer transforms into micelle with increased

Materials and Processes for CO2 Capture, Conversion and Sequestration

May 26, 2018
Author(s)
Winnie K. Wong-Ng, Lan Li, Lawrence P. Cook, Kevin Huang
The book “Materials and Processes for CO2 Capture, Conversion and Sequestration (CCS)” which will be published by John Wiley & Sons, Inc., is a result of the symposium of the same title which took place in 2014 during the MS&T (Materials Science and

Metrology for stable isotope reference materials: 13C/12C and 18O/16O isotope ratio value assignment of pure carbon dioxide gas samples on the Vienna PeeDee Belmnite-CO2 scale using dual-inlet mass spectrometry

May 25, 2018
Author(s)
Abneesh Srivastava, R M. Verkouteren
Isotope ratio measurements have been conducted on a series of isotopically distinct pure CO2 gas samples using the technique of dual-inlet isotope ratio mass spectrometry (DI-IRMS). The influence of instrumental parameters, data normalization schemes on

Performance Testing of Hydraulic Cements: Measuring Sulfate Resistance

May 25, 2018
Author(s)
Chiara F. Ferraris, Paul E. Stutzman, Max A. Peltz
The sulfate resistance of cements used in the construction industry is traditionally assessed by measuring the expansion of a prism of 280 mm (11inch) length and 25 mm (1 inch) square cross section immersed in a sodium sulfate solution for at least one
