Silicon Nanowire Electromechanical Switches for Logic Device Application

July 6, 2007
Author(s)
Qiliang Li, Sang-Mo Koo, Monica D. Edelstein, John S. Suehle, Curt A. Richter
Electromechanical switches consisting of chemical-vapor-deposition grown silicon nanowires suspended over metal electrodes have been fabricated successfully by using single nanowires manipulation and compatible photolithographic processes. The switches are

Correction of Stray Light In Spectroradiometers and Imaging Instruments

July 4, 2007
Author(s)
Yuqin Zong, Steven W. Brown, Keith R. Lykke, Yoshihiro Ohno
Measurement errors from stray light, spectral or spatial, are inevitable and are often the dominant source of error in spectroradiometers and imaging radiometers/photometers. We have developed a simple matrix method for correcting spatial stray light in

Differential Atomic Magnetometry Based on a Diverging Laser Beam

July 3, 2007
Author(s)
Eleanor Hodby, Elizabeth A. Donley, John E. Kitching
We demonstrate a novel atomic magnetometer that uses differential detection of the spatially diverging components of a light field to monitor the Larmor precession frequency of atoms in a thermal vapor. The design is implemented in compact form with a

A Lingua Franca for Trade UN/CEFACT and ISO Jointly Developed Standards

July 2, 2007
Author(s)
Mark E. Palmer
The United Nations Centre for Trade Facilitation and Electronic Business (UN/CEFACT) has as its primary objective the delivery of simple, transparent processes for international trade, thereby making the activities between the buyer, the seller and the

Development of Database on Gas-Chromatographic Retention Properties of Organic Compounds

July 2, 2007
Author(s)
Valeri I. Babushok, Peter J. Linstrom, J J. Reed, I G. Zenkevich, Robert L. Brown, William G. Mallard, Stephen E. Stein
A comprehensive database of gas chromatographic properties of chemical compounds has been developed using multiple literature sources. The collection of retention data for non-polar and polar stationary phases currently contains 292,924 data records for 42

Electrodeposition of Ni in Sub-Micrometer Trenches

July 2, 2007
Author(s)
S D. Kim, John E. Bonevich, Daniel Josell, Thomas P. Moffat
A survey of the effect of cationic, anionic and non-ionic surfactants on the rate and morphological evolution of nickel electrodeposition from a Watts-type bath is presented. Particular attention is given to the prospect for void free filling of sub

Semiconductor Microelectronics and Nanoelectronics Programs

July 2, 2007
Author(s)
Stephen Knight, Joaquin (. Martinez, Michele L. Buckley
The microelectronics industry supplies vital components to the electronics industry and to the U.S. economy, enabling rapid improvements in productivity and in new high technology growth industries such as electronic commerce and biotechnology. The

A Pilot Implementation of the Core Manufacturing Simulation Data Information Model

July 1, 2007
Author(s)
Yung-Tsun T. Lee, Swee K. Leong, Frank H. Riddick, Marcus Johansson, Bjoern J. Johansson
Interoperability between manufacturing software applications and simulation is currently extremely limited, and it has been recognized that there is a great need for methods to improve interoperability. The Core Manufacturing Simulation Data (CMSD)

A Test Implementation of the Core Manufacturing Simulation Data Specification

July 1, 2007
Author(s)
Marcus Johansson, Swee K. Leong, Yung-Tsun T. Lee, Frank H. Riddick, Guodong Shao, Bjoern J. Johansson, Anders Skoogh, P Klingstam
This paper describes an effort of testing the Core Manufacturing Simulation Data (CMSD) information model as a neutral data interface for a discrete event simulation model developed using Enterprise Dynamics. The implementation is based upon a model of a

Air Blast Loading of Cellular Media

July 1, 2007
Author(s)
George A. Gazonas, Joseph Main
Motivated by recent efforts to mitigate blast loading using energy-absorbing materials, this paper investigates the mechanics of uniaxial crushing of cellular sandwich plates under air blast loading using analytical and computational modeling. This model

An Ontology for Assembly Representation

July 1, 2007
Author(s)
Xenia Fiorentini, Iacopo Gambino, V.C. Liang, Sebti Foufou, Sudarsan Rachuri, Mahesh Mani, Conrad E. Bock
Mechanical assemblies are systems composed of modules that are either subassemblies or parts. Traditionally an assembly information model contains information regarding parts, their relationships, and its form. But it is important that the model also

Collaborative Augmented Reality for Better Standards

July 1, 2007
Author(s)
Matthew L. Aronoff, John V. Messina
Concurrent engineering depends on clear communication between all members of the development process. As that communication becomes more and more complex, the quality of the standards used to move and understand that information likewise becomes more and

Data Exchange of Parametric CAD Models Using ISO 10303-108

July 1, 2007
Author(s)
Junhwan Kim, Mike Pratt, Raj G. Iyer, Ram D. Sriram
Modern CAD systems generate feature-based product shape models with parameterization and constraints. Until recently, standards for CAD data exchange among different CAD systems were restricted to the exchange of pure shape information. These standards

Distributed Simulation for Interoperability Testing Along the Supply Chain

July 1, 2007
Author(s)
Sanjay Jain, Frank H. Riddick, Andreas Craens, Deogratias Kibira
The need for interoperability of information systems among supply chain partners has been recognized. A number of standards have been or are being developed to ensure interoperability of applications used along the sup-ply chain. An associated need for

Energy-Level Alignment and Work Function Shifts for Thiol-Bound Monolayers of Conjugated Molecules Self-Assembled on Ag, Cu, Au, and Pt

July 1, 2007
Author(s)
Christopher D. Zangmeister, Laura B. Picraux, Roger D. van Zee, Yuxing Yao, J M. Tour
Photoemission spectra have been used to determine the energy-level alignment and work function of monolayers of 4,4'-bis-(phenylethynyl)benzenethiol, 2 naphthalene thiol, and 3-(naphthalen-2-yl)propane-1-thiol self-assembled on Ag, Cu, Au, and Pt. For each
