Magnetic Properties of Epitaxial CoCr Films with Depth-Dependent Exchange-Coupling Profiles

April 27, 2017
Author(s)
Lorenzo Fallarino, Brian Kirby, Matteo Pancaldi, Patricia Riego, Andrew L. Balk, Casey W. Miller, Paolo Vavassori, A. Berger
We present a study of the compositional and temperature dependent magnetic properties of epitaxial CoCr thin films whose composition has a bathtub-like depth profile Co/Co 1→1- x cCr 0→x c/Co 1-x cCr xc /Co 1-x c→1Cr x c→0^/Co with the highest Cr

Rapid Detection of Fentanyl, Fentanyl Analogues, and Opioids for on-Site or Laboratory Based Drug Seizure Screening using Thermal Desorption DART-MS and Ion Mobility Spectrometry

April 27, 2017
Author(s)
Edward Sisco, Jennifer R. Verkouteren, Jessica L. Staymates, Jeffrey Lawrence
Fentanyl and fentanyl analogues represent a current and emerging threat in the United States as pure illicit narcotics and as cutting agents with heroin. Because of their extreme potency, methods to safely and rapidly detect these compounds are of high

Indicator frameworks

April 26, 2017
Author(s)
Sokwoo Rhee, Christine Kendrick, Abhishek Dubey, Joshua Tan
We develop a diagrammatic tool for constructing correlations between random variables, called an abstract indicator framework. Abstract indicator frameworks are modeled off operational (key performance) indicator frameworks as they are used in city

Towards a Foundation for a Collaborative Replicable Smart Cities IoT Architecture

April 26, 2017
Author(s)
Sokwoo Rhee, Cuong Nguyen, Alexander Nelson, Daniel Hoffman, Greg Toth
The pervasive instrumentation of the physical world with sensors and actuators grants an unprecedented level of information granularity that is useful in decision-making processes. As municipalities and the public sector at large begin to leverage the

Effect of Phosphorylation on a Human-like Osteopontin Peptide

April 25, 2017
Author(s)
Samuel Lenton, Marco Grimaldo, Felix Roosen-Runge, Frank Schreiber, Tommy Nylander, Roger Clegg, Carl Holt, Michael Hartlein, Victoria Garcia Sakai, Tilo Seydel, Susana C. Marujo Teixeira
Osteopontin is a disordered phosphoprotein that is expressed in many species and tissues and has a range of distinct functions. A notable property of more highly phosphorylated isoforms of osteopontin is their ability to sequester nanoclusters of calcium

Photometry (Chapter of Handbook of Visual Optics)

April 25, 2017
Author(s)
Yoshihiro Ohno
The fundamental concept of photometry, the definition of the photometric base unit candela, and the spectral luminous efficiency function V(lambda) are first introduced. Then definitions of important photometric quantities and units, such as luminous flux

Performance of van der Waals Corrected Functionals for Guest Adsorption in the M 2 (dobdc) Metal-Organic Frameworks

April 24, 2017
Author(s)
Bess Vlaisavljevich, Johanna Huck, Zeric Hulvey, Kyuho Lee, Jarad A. Mason, Jeffrey B. Neaton, Jeffrey R. Long, Craig Brown, Dario Alfe, Angelos Michaelides, Berend Smit
Small molecule binding in metal-organic frameworks (MOFs) can be accurately studied both experimentally and computationally, provided the proper tools are employed. Herein, we compare and contrast properties associated with guest binding with density

Using Terahertz Waves to Identify the Presence of Goethite via Antiferromagnetic Resonance

April 24, 2017
Author(s)
Edward J. Garboczi, David F. Plusquellic, Robert D. McMichael, Virgil Provenzano, Paul E. Stutzman, Jack T. Surek, Shin G. Chou, Shuangzhen Wang
Virtually every corrosion detection method reports only the presence of a material phase denoting probable corrosion, not its spectral signature. A signature specific to the type of iron oxide corrosion would not only confirm the presence of corrosion but

LOW-GWP REFRIGERANTS: PERFORMANCE ASSESSMENT AND SELECTION TRADEOFFS

April 23, 2017
Author(s)
Piotr A. Domanski, Riccardo Brignoli, J S. Brown, Andrei F. Kazakov, Mark O. McLinden
The merits of an alternative refrigerant are established based on many attributes including environmental acceptance, chemical stability in the refrigeration system, low toxicity, flammability, efficiency and volumetric capacity. In an earlier work, these

Trace Element Biodistribution in the American alligator (Alligator mississippiensis)

April 23, 2017
Author(s)
Frances Nilsen, Brittany L. Kassim, Patrick Delaney, Ted Lange, Arnold Brunell, Stephen E. Long, Tracey B. Schock, Louis J. Guillette Jr.
Routine monitoring of contaminant levels in wildlife is an important measure of ecosystem health and also can identify potential human health implications. This is particularly important when the monitored species is recreationally hunted for human

Cements in the 21st Century: Challenges, Perspectives, and Opportunities

April 21, 2017
Author(s)
Joseph J. Biernacki, Jeffrey W. Bullard, Gaurav Sant, Nemkumar Banthia, Frederik P. Glasser, Scott Jones, Tyler Ley, Richard A Livingston, Luc Nicoleau, Jan Olek, Florence Sanchez, Rouzbeh Shahsavari, Paul E. Stutzman, Sobolev Konstantin, Tracie Prater
In a book published in 1906, Richard Meade outlined the history of portland cement up to that point1. Since then there has been great progress in portland cement-based construction materials technologies brought about by advances in the materials science

Detector-Independent Verification of Quantum Light

April 21, 2017
Author(s)
Jan Sperling, W.R. Clements, Andreas Eckstein, Meritt Moore, Jelmer Renema, Steven Kolthammer, Sae Woo Nam, Adriana Lita, Thomas Gerrits, Wolfgang Vogel, G.S. Agarwal, Ian Walmsley
We introduce a method for the verification of nonclassical light which is independent of the complex interaction between the generated light and the material of the detectors, which are in our work superconducting transition-edge sensors. This is achieved

Diffusion of water in silica in the absence of stresses

April 21, 2017
Author(s)
Sheldon M. Wiederhorn
In this paper we consider the diffusion of water vapour into silica glass at relatively low temperatures, 25°C to ≈500°C. Extensive studies of such diffusion by others have shown that water diffusion from inert gases behaves differently than diffusion from

The 2016 edition of the Art in Science of MicroTAS

April 21, 2017
Author(s)
Darwin R. Reyes-Hernandez
Dublin, Ireland beheld The 20th International Conference of Miniaturized Systems for Chemistry and Life Sciences (MicroTAS 2016) from October 23 to 27, 2016. The conference not only included a great technical program, but also outreach activities, an
