Understanding How Ligand Functionalization Influences CO 2 and N 2 Adsorption in a Sodalite Metal-Organic Framework

February 25, 2020
Author(s)
Mehrdad Asgari, Rocio Semino, Pascal A. Schouwink, Ilia Kochetygov, Jacob D. Tarver, Olga Trukhina, Rajamani Krishna, Craig Brown, Michele Ceriotti, Wendy L. Queen
In this work, a detailed study is conducted to understand how ligand substitution influences the CO 2 and N 2 adsorption properties of two highly crystalline sodalite MOFs known as Cu-BTT (BTT -3= 1,3,5-benzenetristetrazolate) and Cu-BTTri (BTTri -3 = 1,3

Understanding Superionic Conductivity in Lithium and Sodium Salts of Weakly Coordinating Closo-Hexahalocarbaborate Anions

February 25, 2020
Author(s)
Mathias Jorgensen, Patrick T. Shea, Anton W. Tomich, Joel B. Varley, Marnik Bercx, Sergio Lovera, Radovan Cerny, Wei Zhou, Terrence J. Udovic, Vincent Lavallo, Torben R. Jensen, Brandon C. Wood, Vitalie Stavila
Solid-state ion conductors based on closo-polyborate anions combine high ionic conductivity with a rich array of tunable properties. Cation mobility in these systems is intimately related to the strength of the interaction with the neighboring anionic

Atomic flux circuits

February 23, 2020
Author(s)
Douglas Bopp, Ellyse Taylor, Khoa Le, Susan Schima, Matthew Hummon, John Kitching
Atomic vapors are a crucial platform for precision metrology but in their simplest implementation, a thermal vapor, the intrinsic optical resonances are broadened due to the random and isotropic thermal motion of the atoms. By structuring the container of

Defining Near-term to Long-term Research Opportunities to Advance Metrics, Models, and Methods for Smart and Sustainable Manufacturing

February 21, 2020
Author(s)
Arvind Shankar Raman, Karl Haapala, Kamyar Raoufi, Barbara S. Linke, William Z. Bernstein, KC Morris
Over the past century, research has focused on continuously improving the performance of manufacturing processes and systems - often measured in terms of cost, quality, productivity, and material and energy efficiency. With the advent of smart

Emerging Standards for Nanotechnology-Enabled Medical Products

Alec Weiss, Joshua Kast, Rob Jones, Jeanne Quimby, Rodney Leonhardt, Benjamin Jamroz, Peter Vouras, Dylan Williams, Kate Remley
We provide the frequency response of a high multipath propagation channel using a narrow beamwidth synthetic aperture measurement technique from 26.5 - 40 GHz.

Protecting Controlled Unclassified Information in Nonfederal Systems and Organizations

February 21, 2020
Author(s)
Ronald S. Ross, Victoria Y. Pillitteri, Kelley L. Dempsey, Mark Riddle, Gary Guissanie
The protection of Controlled Unclassified Information (CUI) resident in nonfederal systems and organizations is of paramount importance to federal agencies and can directly impact the ability of the federal government to successfully conduct its essential

A Predictive Modeling Approach to Estimating Seismic Retrofit Costs

February 20, 2020
Author(s)
Juan F. Fung, Siamak Sattar, David T. Butry, Steven L. McCabe
This paper presents a methodology for estimating seismic retrofit costs from historical data. In particular, historical retrofit cost data from FEMA 156 is used to build a predictive model to estimate retrofit costs as a function of building

Practical Guide for Inelastic Mean Free Paths, Effective Attenuation Lengths, Mean Escape Depths, and Information Depths in X-ray Photoelectron SpectroscopyInformation Depths in X-ray Photoelectron Spectroscopy

February 20, 2020
Author(s)
Cedric J. Powell
Information is provided on four terms that are used for different purposes in X-ray photoelectron spectroscopy (XPS): the inelastic mean free path (IMFP), the effective attenuation length (EAL), the mean escape depth (MED), and the information depth (ID)

Sphere Diameter Interferometry with Nanometer Uncertainty

February 20, 2020
Author(s)
Eric S. Stanfield, John R. Stoup, Michael P. Braine, Theodore D. Doiron
In this paper we present both the design details and uncertainty budget for a National Institute of Standards and Technology (NIST)-developed high-accuracy Fizeau-type interferometer specifically adapted to measurement sphere diameter. To do this, we

Grand Canonical Inverse Design of Multicomponent Colloidal Crystals

February 19, 2020
Author(s)
Nathan Mahynski, Evan Pretti, Runfang Mao, Vincent K. Shen, Jeetain Mittal
Inverse design methods are powerful computational approaches for creating colloidal systems which self-assemble into a target morphology by reverse engineering the Hamiltonian of the system. Despite this, these optimization procedures tend to yield

New Insights into Female Humpback Whale (Megaptera novaeangliae) Reproductive Endocrinology Revealed by Steroid Hormone Profile Analysis

February 19, 2020
Author(s)
Greta Dalle Luche, Ashley Boggs, John Kucklick, Jasmin Gross, Darryl Hawker, Susan Bengston Nash
The blubber steroid hormone profiles of 52 female humpback whales migrating along the east coast of Australia were investigated for possible seasonal endocrinological changes associated with reproduction. Individuals were randomly sampled in southeast
