Effect of oxygen pressure on structure and ionic conductivity of epitaxial Li0.33La0.55TiO3 solid electrolyte thin films produced by pulsed laser deposition

December 16, 2016
Author(s)
Leonid A. Bendersky, Bharathi Kamala, Haiyan Tan, Saya Takeuchi, Haoting Shen, Jongmoon Shin, I. Takeuchi
We report on the ionic conductivity and the effect of oxygen partial pressure during the growth of Li0.33La0.55TiO3 (LLTO) epitaxial films grown on SrTiO3 (STO) (100) and (111) substrates and explore some distinct conductivity behavior. The films are

Floating Zone Growth of a-Na 0.90 MnO 2 Single Crystals

December 16, 2016
Author(s)
Rebecca Dally, Raphaele Clement, Robin Chisnell, Stephanie Taylor, Megan Butala, Vicky Doan-Nguyen, Mahalingam Balasubramanian, Jeffrey W. Lynn, Clare P. Grey, Stephen D. Wilson
Single crystal growth of α-Na xMnO 2 (x=0.90) is reported via the floating zone technique. The conditions required for stable growth and intergrowth-free crystals are described along with the results of trials under alternate growth atmospheres. Chemical

Measurements and Scoring Procedures for Footwear Impression Comparisons

December 16, 2016
Author(s)
Martin Herman
A software system under development at NIST, called SHOECALC, will be described. It is designed to help both researchers and footwear examiners in the assessment of metrics or scoring procedures that provide objective characterizations of correspondences

Separation, Sizing, and Quantitation of Engineered Nanoparticles in an Organism Model Using Inductively Coupled Plasma Mass Spectrometry and Image Analysis

December 16, 2016
Author(s)
Monique E. Johnson, Shannon Hanna, Antonio R. Montoro Bustos, Christopher M. Sims, Lindsay C. Elliott, Babak Nikoobakht, John T. Elliott, Richard D. Holbrook, Keana C. Scott, Karen E. Murphy, Elijah J. Petersen, Lee L. Yu, Bryant C. Nelson, Akshay Lingayat, Adrian C. Johnston
For environmental studies assessing uptake of orally ingested engineered nanoparticles (ENPs), a key step in ensuring accurate quantification of ingested ENPs is efficient separation of the organism from ENPs that are either nonspecifically adsorbed to the

A better-than-3n lower bound for the circuit complexity of an explicit function

December 15, 2016
Author(s)
Magnus G. Find, Alexander Golovnev, Edward Hirsch, Alexander Kulikov
We consider Boolean circuits over the full binary basis. We prove a $(3+\frac{1}{86})n-o(n)$ lower bound on the size of such a circuit for an explicitly defined predicate, namely an affine disperser. This improves the $3n-o(n)$ bound of Norbert Blum (1984)

Contour Metrology using Critical Dimension Atomic Force Microscopy

December 15, 2016
Author(s)
Ndubuisi G. Orji, Ronald G. Dixson, Boon Ping Ng, Andras Vladar, Michael T. Postek
The critical dimension atomic force microscope (CD-AFM) has been proposed as an instrument for contour measurement and verification – since its capabilities are complementary to the widely used scanning electron microscope (SEM). Although data from CD-AFM

Network Charter: Manufacturing USA

December 15, 2016
Author(s)
Michael F. Molnar
Under the authority of the Revitalize American Manufacturing and Innovation Act of 2014, the Secretary of Commerce shall establish the Network for Manufacturing Innovation, generally called the Manufacturing USA network. The network, along with its

Online Airtightness Calculator for the US, Canada and China

December 15, 2016
Author(s)
Som Shrestha, Lisa Ng, Steven Emmerich, Diana Hun, Laverne Dalgleish
The contribution of air leakage to heating and cooling loads has been increasing as the thermal resistance of building envelopes continues to improve. Easy-to-access data are needed to convince building owners and contractors that enhancing the

Real space mean-field theory of a spin-1 Bose gas in synthetic dimensions

December 15, 2016
Author(s)
Ian B. Spielman, Justin H. Wilson, Hilary Hurst, Jed Pixley, Stefan Natu
The internal degrees of freedom provided by ultracold atoms give a route for realizing higher dimensional physics in systems with limited spatial dimensions. Non-spatial degrees of freedom in these systems are dubbed “synthetic dimensions”. This connection

Transactive Energy Application Landscape Scenarios

December 15, 2016
Author(s)
David G. Holmberg, David Hardin, Ronald Melton, Ron Cunningham, Steve Widergren
This paper presents an analysis of the transactive energy (TE) application landscape, specifically examining the transactive process, business functions, actors in different smart grid (SG) application domains, and time scales. These process steps

60 Year Anniversary of Applied Radiation and Isotopes

December 14, 2016
Author(s)
Bert M. Coursey
Those readers who have a library with the first bound copies of ARI may find it enjoyable to compare Volume 1, No.1 from 1956 with an issue from Volume 118 in 2016. The range of applications has shifted away from agricultural and industrial uses of

Trapping States of Mixed-Isomer Organic Semiconductors within Organic Field-Effect Transistors

December 14, 2016
Author(s)
Peter Diemer, Jacori Hayes, Evan Welchman, Rawad Hallani, Sujitra Pookpanratana, Christina Hacker, Curt A. Richter, Timo Thonhauser, Oana Jurchescu
Organic field effect transistor (OFET) performance is dictated by the composition and geometry of the device, as well as the quality of the organic semiconductor (OSC) film, which strongly depends on the purity and structural defects. When present, these

Guide Brief 5: Assessing Energy System Dependencies

December 13, 2016
Author(s)
Community Resilience Program NIST
A major aspect of characterizing the built environment is identifying key infrastructure dependencies that may exist. Some of these dependencies are obvious; others are not. This Guide Brief focuses on Step 2, understanding the built environment, and

In situ Atomic-Scale Probing of Reduction Dynamics of 2-Dimensional Fe2O3 Nanostructures

December 13, 2016
Author(s)
Wenhui Zhu, Jonathan P. Winterstein, Wei-Chang Yang, Lu Yuan, Renu Sharma, Guangwen Zhou
Atomic-scale structure dynamics and phase transformation pathway was probed, in situ, during the reduction of bi-crystalline Fe2O3 nanostructures in H2 by using an environmental transmission electron microscope. It was found that the reduction commenced
