In Situ Nanoscale Characterization of Water Penetration through Plasma Polymerized Coatings

August 1, 2018
Author(s)
Yang Zhou, Brian Patrick Josey, Emmanuel Anim-Danso, Brian B. Maranville, Jenia Karapetrova, Zhang Jiang, Qixin Zhou, Ali Dhinojwala, Mark D. Foster
The search continues for means of making quick determinations of the efficacy of a coating for protecting a metal surface against corrosion. One means of reducing the time scale needed to differentiate the performance of different coatings is to draw from

Progress in Ground-source Heat Pumps Using Natural Refrigerants

August 1, 2018
Author(s)
Wei Wu, Harrison Skye, Lingnan Lin
Hydrofluorocarbon (HFC) and hydrochlorofluorocarbon (HCFC) refrigerants with high Global Warming Potential (GWP) will be phased down significantly under the Montreal Protocol. Natural refrigerants have a very low GWP and are inexpensive, and therefore are

Stone-Cold Low Temperature Cathodoluminescence Spectrometry of Quartz (SiO2)

August 1, 2018
Author(s)
Edward P. Vicenzi, Scott A. Wight
Cathodoluminescence (CL) studies of quartz have been useful in Earth sciences for understanding geological cycling, quantitative trace element concentrations and thermal properties of crystallization, as well as serving as a petrographic aid to interpret

Aggregation and Solubility of a Model Conjugated Donor-Acceptor Polymer

July 31, 2018
Author(s)
Daniel R. Reid, Nicholas E. Jackson, Alexander J. Bourque, Chad R. Snyder, Ronald L. Jones, Juan de Pablo
In organic semiconductors, solution-phase polymer structure and aggregation have a strong influence on device morphology and performance. Thus, understanding solubility of conjugated polymers is crucial for their rational design. Using a combination of

Cybertrust in the IoT Age

July 31, 2018
Author(s)
Jeff Voas, D. Richard Kuhn, Constantinos Kolias, Angelos Stavrou, Georgios Kambourakis
The Internet of Things generates new opportunities but creates new challenges with respect to trustworthiness. Computing, architecture, and verification changes are inevitable to meet these challenges, particularly if predictions of 20 billion to 50

Reasoning about Smart City

July 31, 2018
Author(s)
Edward R. Griffor, Martin J. Burns, David A. Wollman, Marcello Balducinni, Claire Vishik, Michael Huth
Smart Cities are complex environments, comprising diverse cyber-physical systems (CPS), including Internet of Things (IoT). Smart Cities pose challenges of scale, integration, interoperability, sophisticated processes, governance, human elements

Using the IES-City Framework

July 31, 2018
Author(s)
Martin J. Burns, Joe Manganelli
This paper introduces a use case for using the IES-City Framework artifacts and methodology in the acquisition of a new smart city feature. Involving city management and potential service providers, it shows how this new feature can be acquired with

Voices of First Responders - Identifying Public Safety Communication Problems: Findings from User-Centered Interviews, Phase 1, Volume 1

July 31, 2018
Author(s)
Yee-Yin Choong, Shanee T. Dawkins, Susanne M. Furman, Kristen Greene, Sandra S. Prettyman, Mary F. Theofanos
The public safety community is in the process of transitioning from the use of land mobile radios to a technology ecosystem including a variety of broadband data sharing platforms. Successful deployment and adoption of new communication technology relies
