Calculations of the Energy of Mixing Carbon Nanotubes With Polymers

February 19, 2017
Author(s)
Marc R. Nyden, Stanislav Stoliarov
A method for estimating the free energy of mixing CNTs with polymers is presented. The formation of the nanocomposite is analyzed in terms of a simple path in which the nanotubes are exfoliated from a bundle and dispersed in a distorted polymer with

CD ROM Guide for NIST Crystal Data NIST Standard Reference Database 3

February 19, 2017
Author(s)
Vicky L. Karen, S L. Young, Alan D. Mighell
The NIST Crystallographic Data Center collects, evaluates and disseminates data on solid-state materials. NIST Crystal Data is a comprehensive database with chemical, physical and crystallographic information on all classes of well-characterized substances

CFD-Based Modeling of Combustion and Suppression in Compartment Fires

February 19, 2017
Author(s)
Arnaud Trouve, Andre Marshall
This chapter is aimed at illustrating contemporary Computational Fluid Dynamics (CFD) capabilities for compartment fire applications. We choose to use the Fire Dynamics Simulator (FDS) for illustration purposes. FDS is developed by the National Institute

Chapter 48: Robotics in Construction

February 19, 2017
Author(s)
Kamel S. Saidi, Jonathan O'Brien, Alan M. Lytle
This chapter introduces the various construction automation concepts that have been developed over the past few decades and presents examples of construction robots that are in current use (as of 2006) and/or in various stages of research and development.

Characterization of the Mirror Region With Atomic Force Microscopy

February 19, 2017
Author(s)
Sheldon M. Wiederhorn, Jose Lopez-Cepero, Jay S. Wallace, Jean-Pierre Guin, Theo Fett
In this paper we use atomic force microscopy to investigate the roughness of the mirror region in silica glass. We demonstrate a decrease in surface RMS Roughness from about 0.5 nm to about 0.4 nm with increasing stress intensity factor (0.5KIc to about 0

Combinatorial Tools for Inorganic Thin Films

February 19, 2017
Author(s)
Peter K. Schenck, Debra L. Kaiser
We report the deveopment of a novel dual beam - dual target pulsed laser deposition (PLD) system for the production of compositionally-graded library films for combinatorial thin film materials research. In-situ process monitoring, including high-speed

Contact Area Correction for Random Surface Roughness on Nanoadhesion

February 19, 2017
Author(s)
Seung H. Yang, Huan Zhang, Stephen M. Hsu
Atomic force microscopes (AFM) have been used to measure adhesion at nanoscale between two surfaces. Colloidal probes are often utilized for such measurements because they provide much lower contact pressures and controlled contact geometry, facilitating

Contact Damage Produced in Si and MgO by Nanoindentation

February 19, 2017
Author(s)
B Hockey
TEM has been used to characterize the defect structures produced in Si and Mgo by Berkovich indentation at loads ranging from 0.1 mN to 5 mN. Plane-section observations are used to describe the nature of the defects and their spatial distribution about the

Continuous Monitoring of Particles in an Occupied Home for the Year 2000

February 19, 2017
Author(s)
L A. Wallace, Cynthia H. Reed
Continuous monitors were employed for one year in an occupied townhouse to measure ultrafine, fine and coarse particles, air change rates, wind speed and direction, temperature and relative humidity. A main objective was to document long-term variation in

Controlled Synthesis of Single-Crystalline InN Nanorods

February 19, 2017
Author(s)
Igor Levin, Albert Davydov, O M. Kryliouk, Hyun Jong Park, YongSun Won, T J. Anderson, J P. Kim, J A. Freitas
Single-crystalline InN nanorods were successfully grown on c-Al203, GaN, and Si substrates by non catalytic, template-free hydride metal-organic vapor phase epitaxy (H-MOVPE). Stable gas-phase oligomer formation is proposed as the nucleation mechanism for
