Nicholas Geitner, Christine O. Hendren, Geert Cornelis, Ralf Kaegi, Jamie Lead, Gregory Lowry, Iseult Lynch, Bernd Nowack, Elijah Petersen, Emily Bernhardt, Scott Brown, Warren Chan, Camille de Garidel-Thoron, Jaydee Hanson, Stacey Harper, Kim Jones, Frank von der Kammer, Alan Kennedy, Justin Kidd, Cole Matson, Christopher Metcalf, Joel Pedersen, Willie Peijnenburg, Joris Quik, Sonia Rodriguez, Jerome Rose, Phil Sayre, Marie Simonin, Claus Svendsen, Robert Tanguay, Nathalie Tukenji, Tom van Teunenbroek, Gregory Thies, Yuan Tian, Jacelyn Rice, Jie Liu, Jason Unrine, Marina Vance, Jason White, Mark Wiesner
The chemical composition and properties of environmental media play defining roles in determining nanomaterial (NM) transport, fate, biouptake, and even organism response. To compare and interpret experimental data, it is essential that sufficient context

Optimal Series Resistors for On-Wafer Calibrations

November 8, 2019
Author(s)
Jasper A. Drisko, Richard A. Chamberlin, James C. Booth, Nathan D. Orloff, Christian J. Long
The series resistor is a common on-wafer device typically used in the series-resistor calibration and for estimating the capacitance per unit length of coplanar waveguide transmission lines. While much work has been done using series resistors, this paper

A SDN-based Network Layer for Edge Computing

November 7, 2019
Author(s)
An Wang, Zili Zha, Yang Guo, Songqing Chen
The advanced big data analytical technologies and ever-expanding Internet-of-Things (IoT) devices and applications drive the new computing paradigm, Edge Computing. It significantly improves network performance by collecting and processing data locally or

ENTHALPY OF FORMATION OF AQUEOUS HYDROFLUORIC ACID: REVISION NEEDED?

November 7, 2019
Author(s)
Yauheni Paulechka, Andrei F. Kazakov
Accurate enthalpies of formation of hydrofluoric acid in the gas and liquid states as well as in aqueous solutions are critical for reduction and interpretation of combustion calorimetry data for fluorinated compounds. Analysis of current recommendations

Metabolomics Test Materials for Quality Control: A Study of a Urine Materials Suite

November 7, 2019
Author(s)
Dan Bearden, David A. Sheen, Yamil Simon, Bruce A. Benner Jr., Werickson Fortunato de Carvalho Rocha, Niksa Blonder, Katrice A. Lippa, Richard Beger, Laura Schnackenberg, Jinchun Sun, Khyati Mehta, Amrita Cheema, Haiwei Gu, Ramesh Marupaka, Nagana Gowda, Daniel Raftery
There is a lack of experimental reference materials and standards for metabolomics measurements, such as urine, plasma, and other human fluid samples. Reasons include difficulties with supply, distribution, and dissemination of information about the

Throughput Analysis between Unicast and MBSFN from Link Level to System Level

November 7, 2019
Author(s)
Chunmei Liu, Chen Shen, Jack Chuang, Richard A. Rouil, Hyeong-Ah Choi
Public safety incidents typically involve significant amount of group traffic. This paper initializes our study in exploring the potential spectrum savings and improvement in first responders experience by using Multicast Broadcast Single Frequency Network

Anomaly in the Virial Expansion of IAPWS-95 at Low Temperatures

November 6, 2019
Author(s)
Allan H. Harvey
In the standard reference equation of state for the thermodynamic properties of water, known as IAPWS-95, the fourth virial coefficient D(T) becomes abnormally large in magnitude at temperatures below approximately 300 K. At conditions where a virial

Options for Low-GWP Refrigerants

November 6, 2019
Author(s)
Mark O. McLinden, Andrei F. Kazakov, J S. Brown, Riccardo Brignoli, Ian H. Bell, Piotr A. Domanski
We summarize a systematic examination of possible low-GWP (global warming potential) replacements for the HFC (hydrofluorocarbon) refrigerants currently used in small air-conditioning systems. The methodology identified the optimal thermodynamic parameters

Contactless Resonant Cavity Dielectric Spectroscopic Studies of Recycled Office Papers

November 5, 2019
Author(s)
Mary Kombolias, Jan Obrzut, Michael T. Postek, Dianne L. Poster, Yaw S. Obeng
Current product composition and quality test methods for the paper and pulp industry are rooted in wet-bench chemistry techniques which are highly subjective. These techniques have rather limited utility and cannot be used to distinguish between virgin and

Flow Resistance & Structures in Viscoelastic Channel Flows at Low Re

November 5, 2019
Author(s)
Boyang Qin, Paul Salipante, Steven Hudson, Paulo E. Arratia
The flow of viscoelastic fluids in channels and pipes remain poorly understood, particularly at low Reynolds numbers. Here, we investigate the flow of polymeric solutions in straight channels using pressure measurements and particle tracking. The law of

Ross H. Colman, H. Esma Okur, Winfried Kockelmann, Craig Brown, Annette Sans, Claudia Felser, Martin Jansen, Kosmas Prassides
Cs 4O 6 is a mixed valence molecular oxide with a cubic structure, comprising valency-delocalized O 2 4/3- units and with properties highly sensitive to cooling protocols. Here we use neutron powder diffraction to authenticate that, while upon deep

Human Factors in Smart Home Technologies Workshop Summary
