Probing the Interfacial Structure of Bilayer Plasma Polymer Films via Neutron Reflectometry

May 1, 2016
Author(s)
Yali Li, Andrew Nelson, Christopher D. Easton, David R. Nisbet, John S. Forsythe, Benjamin Muir, Dan A. Neumann
Bilayer plasma polymer (PP) films were examined using a combination of X-ray and neutron reflectometry and X-ray photoelectron spectroscopy to gain an understanding of the interfacial structures that form between the films. Three different PP films were

Analysis and Optimization based on Reusable Knowledge Base of Process Performance Models

April 29, 2016
Author(s)
Alexander Brodsky, Guodong Shao, Mohan Krishnamoorthy, Anantha Narayanan Narayanan, Daniel Menasce?, Ronay Ak
In this paper, we propose an architectural design and software framework for fast development of descriptive, diagnostic, predictive, and prescriptive analytics solutions for dynamic production processes. The proposed architecture and framework will

Diagnostics for geometric performance of machine tool linear axes

April 29, 2016
Author(s)
Gregory W. Vogl, M A. Donmez, Andreas Archenti
Machine tools degrade during operations, yet knowledge of degradation is elusive; accurately detecting degradation of linear axes is mainly a manual and time-consuming process. Thus, manufacturers need automated and efficient methods to diagnose the

Intensity Ratio of Resonant Raman Modes for (n,m) Enriched Semiconducting Carbon Nanotubes

April 29, 2016
Author(s)
Yanmei Piao, Jeffrey R. Simpson, Jason K. Streit, Geyou Ao, Ming Zheng, Angela R. Hight Walker
Relative intensities of resonant Raman spectral features, specifically the radial breathing mode (RBM) and G modes, of eleven chirality-enriched single-wall carbon nanotube (SWCNT) species were established under second-order optical transition excitation

Bottom-Up Colloidal Crystal Assembly with a Twist

April 28, 2016
Author(s)
Nathan Mahynski, Lorenzo Rovigatti, Christos Likos, Athanassios Panagiotopoulos
Globally ordered colloidal crystal lattices have broad utility in a wide range of optical and catalytic devices, for example, as photonic bandgap materials. However, the self-assembly of stereospecific structures is often confounded by polymorphism. Small

Hardware Security Thorough Supply Chain Assurance

April 28, 2016
Author(s)
Yaw S. Obeng, David A. Brown, Colm Nolan
This paper examines the current issues pertaining to the hardware security and how they could affect the overall security of applications such as the internet of things. Specifically, we review the ongoing industry-led activities aimed at mitigating the

Optical Fluorescence Microscopy for Spatially Characterizing Electron Transfer across a Solid-Liquid Interface on Heterogeneous Electrodes

April 28, 2016
Author(s)
Eric A. Choudhary, Jeyavel Velmurugan, James M. Marr, James A. Liddle, Veronika A. Szalai
Heterogeneous catalytic materials and electrodes are used for (electro)chemical transformations, including those important for energy storage and utilization. Due to the heterogeneous nature of these materials, activity measurements with sufficient spatial
