Formation of a crack-free, hybrid skin layer with tunable surface topography and improved gas permeation selectivity on elastomers using gel-liquid infiltration polymerization

September 11, 2017
Author(s)
Justin Gorham, Jason Killgore, Maryam Omidvar, Haiqing Lin, Frank W. DelRio, Lewis M. Cox, Zheng Zhang
Liquid-liquid interfacial polymerization (ll-IP) is conventionally used for manufacturing bulk polymers like nylon, as well as forming barrier layers for reverse osmosis membranes. In this work, we explore the use of gel-liquid infiltration polymerization

New measurement of the Boltzmann constant k by acoustic thermometry of helium-4 gas

Author(s)
Laurent Pitre, Fernando Sparasci, Michael R. Moldover, Cecile Guianvarch, Catherine Martin, Martin Himbert, Mark Plimmer, James B. Mehl, Giuliano Albo, Bo Gao, Lara Risegari
The SI unit of temperature will soon be redefined in terms of a fixed value of the Boltzmann constant k derived from an ensemble of measurements worldwide. We report on a new determination of k using acoustic thermometry of helium-4 gas in a 3-litre quasi

The Cytosolic Domain of T Cell Receptor z Associates with Membranes in a Dynamic Equilibrium and and Deeply Penetrates the Bilayer

September 11, 2017
Author(s)
Kerstin Zimmermann, Rebecca Eells, Frank Heinrich, Stefanie Rintoul, Brian Patrick Josey, Prabhanshu Shekhar, Mathias Loesche, Lawrence J. Stern
Interactions between lipid bilayers and the membrane-proximal regions of membrane-associated proteins play important roles in regulating membrane protein structure and function. The T cell antigen receptor (TCR) is an assembly of eight single-pass membrane

Cybersecurity Framework Manufacturing Profile

Keith A. Stouffer, Timothy A. Zimmerman, CheeYee Tang, Joshua Lubell, Jeffrey A. Cichonski, John McCarthy
[Superseded by NISTIR 8183 (September 2017, Includes updates as of May 20, 2019)]This document provides the Cybersecurity Framework (CSF) implementation details developed for the manufacturing environment. The "Manufacturing Profile" of the Cybersecurity

Under-Reporting of Wildland Fires in NFIRS: California

September 8, 2017
Author(s)
David T. Butry, Douglas S. Thomas
The absence of a comprehensive database on fire occurrence along with the possibility of inaccurate data entry in current datasets means that some proportion of wildfires is not reported and the damage they cause is to some extent unknown. Without this

Business Process Context for Message Standards

September 7, 2017
Author(s)
Nenad Ivezic, Miroslav Ljubicic, Marija Jankovic, Boonserm Kulvatunyou, Scott Nieman, Garret Minakawa
Despite unrelenting increase in complexity of message standards for enterprise systems integrations, there are no effective means to address this complexity issue in practice. We describe an effort to address the issue by advancing message standards
