David R. Schultz, Heman Gharibnejad, Thomas Cravens, Stephen Houston
To improve the physical completeness of the data previously calculated [Schultz et al. ADNDT 113, 1 (2016)] to enable modeling of the effects of secondary electrons produced by energetic ion precipitation at Jupiter, we extend the treatment to include

interlab: A Python module for analyzing interlaboratory comparison data

March 15, 2019

David A. Sheen
interlab was developed as a software tool to perform consensus analysis on spectral data from interlaboratory studies. It is designed to estimate the spread in the spectral data and to identify possible outliers among both spectral populations and

Bubble Point Measurements of Neopentane + Ethane Mixtures

March 14, 2019
Author(s)
Elisabeth Mansfield, Vladimir Diky
Bubble point measurements have been taken on three compositions of neopentane + ethane systems. The results are modeled with a Peng-Robinson equation with symmetrical mixing rule and a Helmholtz-energy based 4-parameter model. Interaction parameters for

Hao Li, Libo Li, Rui-Biao Lin, Giorgio Ramirez, Wei Zhou, Rajamani Krishna, Zhangjing Zhang, Shengchang Xiang, Banglin Chen
Separating acetylene from light hydrocarbon mixtures like ethylene is a very important process for downstream industrial applications. Herein, we report a new MOF [CuL 2(SiF 6)](UTSA-220, L = 1E,2E)-1,2-bis(pyridin-4-ylmethylene)hydrazine) with dual

Multi-Energy X-Ray Tomography of an Optical Fiber: The Role of Spatial Averaging

March 14, 2019
Author(s)
Zachary H. Levine, Adele P. Peskin, Edward J. Garboczi, Andrew Holmgren
Using a commercial X-ray tomography instrument, we have obtained reconstructions of a graded-index optical fiber with voxels of edge length 1.05 µm at 12 tube voltages. The fiber manufacturer created a graded index in the central region by varying the

Pore Space Partition within a Metal-Organic Framework for Highly Efficient C 2 H 2 /CO 2 Separation

Yingxiang Ye, Zhenlin Ma, Rui-Biao Lin, Rajamani Krishna, Wei Zhou, Quanjie Lin, Zhangjing Zhang, Shengchang Xiang, Banglin Chen
The pore space partition (PSP) approach has been employed to realize a novel porous MOF (FJU-90) with dual functionalities for the challenging C 2H 2/CO 2 separation under ambient conditions. By virtue of a triangular ligand (Tripp = 2,4,6-tris-(4-pyridyl

Probing Membrane Association of a-Synuclein Domains with VDAC Nanopore Reveals Unexpected Binding Pattern

March 14, 2019

The Intelligent Building Agents Laboratory (IBAL) at the National Institute of Standards and Technology (NIST) will be used to develop and evaluate advanced control systems for commercial building heating, ventilation, and air conditioning (HVAC)

Influence of Knot Complexity on Glass-Formation in Ring Polymer Melts

March 13, 2019
Author(s)
Luis F. Vargas Lara, Beatriz Pazmino, Jack F. Douglas
We perform molecular dynamic simulations on a coarse-grained polymer melt to study the dynamics of glass-formation in ring polymer melts of variable knot complexity. After generating melts of non-concatenated polymeric rings having a range of minimum
