Functionalized MoS2 nanorribon as a capacitive displacement sensor for DNA sequencing

September 13, 2016
Author(s)
Alex Smolyanitsky, Tsjerk A. Wassenaar, Eugene Paulechka, Kenneth Kroenlein
We propose an aqueous functionalized molybdenum disulfide nanoribbon suspended over a solid electrode as a capacitive displacement sensor aimed at determining the DNA sequence. The detectable sequencing events arise from the combination of Watson–Crick

The Origin and Application of Leakage-Infiltration Ratios

September 13, 2016
Author(s)
Andrew Persily, Max Sherman, Benjamin Jones
Infiltration is the ingress of outdoor air under normal operating conditions through adventitious openings located in the façade of a building. The importance of reducing infiltration to save energy is highlighted by standards and building codes in many

Three-Dimensional Protonic Conductivity in Porous Organic Cage Solids

September 13, 2016
Author(s)
Ming Liu, Linjiang Chen, Scott Lewis, Samantha Y. Chong, Marc A. Little, Tom Hasell, Iain M. Aldous, Craig Brown, Martin W. Smith, Carole A. Morrison, Laurence J. Hardwick, Andrew I. Cooper
Proton conduction is a fundamental process in biology and in devices such as proton exchange membrane fuel cells. To maximize proton conduction, 3-D conduction pathways are preferred over 1-D pathways, which prevent proton conduction in two-dimensions

Monochromatic Measurements of the JPSS-1 VIIRS Polarization Sensitivity

September 12, 2016
Author(s)
Steven W. Brown, Keith R. Lykke, Jeff McIntire, David Moyer, Eugene Waluschka, Hassan Oudrari, Xiaoxiong Xiong
The polarization sensitivity is a critical parameter that must be characterized for spaceborne remote sensing instruments designed tomeasure reflected solar radiation such as the first Joint Polar-orbiting Satellite System (JPSS-1) Visible Infrared Imaging

OpenCalphad thermodynamic software interface including parallelization

September 12, 2016
Author(s)
Bo Sundman, Ursula R. Kattner, Christophe Sigli, Matthias Stratmann, Romain Le Tellier, Mauro Palumbo, Suzana G. Fries
Thermodynamic data are needed for all kind of simulations of materials processes. For example, for kinetic models thermodynamic quantities, such as chemical potentials, driving forces for precipitation, thermodynamic factors for converting mobilities to

Results of The 2015 NIST Language Recognition Evaluation

September 12, 2016
Author(s)
Hui Zhao, Desire Banse, G R. Doddington, Craig Greenberg, Audrey N. Tong, John M. Howard, Alvin F. Martin, Jaime Hernandez-Cordero, Lisa Mason, Douglas A. Reynolds, Elliot Singer
In 2015, NIST conducted the most recent in an ongoing series of Language Recognition Evaluations (LRE) meant to foster research in language recognition. The 2015 Language Recognition Evaluation (LRE15) featured 20 target languages grouped into 6 language

Conformational Nature of DNAGrafted Chains on Spherical Gold Nanoparticles

September 10, 2016
Author(s)
Jack F. Douglas, Fernando Vargas-Lara
We investigate the conformational state of a simple, coarse–grained molecular model for single–stranded DNA chains (ss-DNA) grafted onto spherical symmetric gold nanoparticles (NPs) and of the grafted layer as a whole by molecular dynamic simulations. In

Effective Field Theory for Rydberg Polaritons

September 9, 2016
Author(s)
Michael Gullans, Yidan Wang, Jeff D. Thompson, Qiyu Liang, Vladan Vuletic, Mikhail D. Lukin, Alexey V. Gorshkov
We develop an effective field theory (EFT) to describe the few- and many-body propagation of one- dimensional Rydberg polaritons. We show that the photonic transmission through the Rydberg medium can be found by mapping the propagation problem to a

Development of Potential Organic-Molecule-Based Hydrogen Storage Materials: Converting C-N Bond-Breaking Thermolysis of Guanidine to N-H Bond-Breaking Dehydrogenation

September 8, 2016
Author(s)
Xiuquan Zhou, Wei Zhou, Terrence J. Udovic, Taner N. Yildirim, John J. Rush, Efrain E. Rodriguez, Hui Wu
The small organic molecule guanidine CN 3H 5 can be anionized via a facile reaction with alkali-metal hydrides or amides with the formation of metal guanidinates (MCN 3H 4) and their guanidine adducts. They crystal structures and thermal decomposition

Magnetic Yoking and Tunable Interactions in FePt-Based Hard/Soft Bilayers

September 8, 2016
Author(s)
Dustin Allen Gilbert, Jung-Wei Liao, Brian J Kirby, Michael Winklhofer, Chih-Huang Lai, Kai Liu
Assessing and controlling magnetic interactions in magnetic nanostructures are critical to nanomagnetic and spintronic explorations, such as magnetic recording media, permanent magnets, magnetic memory and logic devices, etc. Here we demonstrate an

Mechanical characterization of sequentially layered photo-clickable thiol-ene hydrogels

September 8, 2016
Author(s)
Aaron Aziz, Joseph Wahlquist, Aaron Sollner, Virginia L. Ferguson, Frank W. DelRio, Stephanie Bryant
Multi-layer hydrogels formed from crosslinked poly(ethylene glycol) (PEG) have shown promise for applications in tissue engineering ranging from vasculature to musculoskeletal tissues. The objective of this work was to characterize the interface resulting

Networked Engineering Notebooks for Smart Manufacturing

September 8, 2016
Author(s)
Peter O. Denno
A goal of the industrial internet is to make information about manufacturing processes and resources available wherever decision making may be required. Agile use of information is a cornerstone of data analytics, but analytical methods more generally

Atom Probe Tomography Analysis of Ag Doping in 2D Layered Material (PbSe)5(Bi2Se3)3

September 7, 2016
Author(s)
Arunima Singh, Albert Davydov, Francesca M. Tavazza, Lincoln J. Lauhon, Xiaochen Ren, Mercouri G. Kanatzidis, Lei Fang
Impurity doping in two-dimensional (2D) materials can provide a route to tuning electronic properties, so it is important to be able to determine the distribution of dopant atoms within and between layers. Here we report the tomographic mapping of dopants
