A METHOD FOR DETERMINING THE ENVIRONMENTAL FOOTPRINT OF INDUSTRIAL PRODUCTS USING SIMULATION

December 14, 2011
Author(s)
Erik Lindskog, Linus Lundh, Jonatan K. Berglund, Yung-Tsun Lee, Anders Skoogh, Bjorn Johansson
Effective assessment and communication of environmental footprint is increasingly important to process development and marketing purposes. Traditionally, static methods have been applied to analyze the environmental impact during a product's life cycle

Energy Efficiency Analysis for a Casting Production System

December 14, 2011
Author(s)
Jonatan K. Berglund, John L. Michaloski, Swee K. Leong, Guodong Shao, Frank H. Riddick, Jorge Arinez, Stephan Biller
A growing number of manufacturing industries are initiating efforts to address sustainability issues. A study by the National Association of Manufacturers indicated that the manufacturing sector currently accounts for over a third of all energy consumed in

Electrochemical Micromachining of NiTi Shape Memory Alloys with Ultrashort Voltage Pulses

December 8, 2011
Author(s)
Joseph Maurer, John Hudson, Steven E. Fick, Thomas P. Moffat, Gordon A. Shaw
Electrochemical micromachining (ECMM) with ultrashort voltage pulses has been used to fabricate microstructures on a NiTi shape memory alloy (SMA). Because of its unique properties, NiTi is a desirable material for use in various applications including

NON-CONTACT DIMENSIONAL MEASUREMENTS OF BIPOLAR FUEL CELL PLATES

November 15, 2011
Author(s)
Balasubramanian Muralikrishnan, Wei Ren, Dennis S. Everett, Eric S. Stanfield, Theodore D. Doiron
Non-contact dimensional measurement of fuel cell plates is critical to the eventual rapid manufacture by supporting in-process measurement and control. This need has been identified by the Department of Energy’s Hydrogen Program, and by numerous

Capacitive readout technique for studies of dissipation in GaN nanowire mechanical resonators

November 11, 2011
Author(s)
Kristine A. Bertness, Joshua R. Montague, Norman A. Sanford, Victor Bright, Charles T. Rogers
A variable-temperature, homodyne reflectometry measurement technique for detecting nanoscale mechanical motion has recently been developed. We have extended this technique to make the first all-electrical measurements of an ensemble of as-grown, c-axis

Metamodels towards Improved Domain Modeling for Semantic Inferencing

October 3, 2011
Author(s)
Paul W. Witherell, Anantha Narayanan Narayanan, Jae H. Lee, Sudarsan Rachuri
As information requirements have increased, domain models have become increasing complex and difficult to manage. Though domain-specific languages have been developed for domain experts, increasing their expressivity and decreasing their complexity, their

ROADMAPPING MANUFACTURING NEEDS FOR MEMS TECHNOLOGIES

September 30, 2011
Author(s)
Michael Gaitan, Karen Lightman
This report summarizes issues in manufacturing from the 2011 iNEMI MEMS Technology Roadmap, and shares the authors’ observations from the 2011 MEMS Industry Group’s (MIG) Workshop on Device Testing and the 2012 ITRS MEMS Technology Working Group’s (TWG)

Development of the Metrology and Imaging of Cellulose Nanocrystals

September 19, 2011
Author(s)
Michael T. Postek, Andras Vladar, John A. Dagata, Natalia Farkas, Bin Ming, Ryan Wagner, Arvind Raman, Robert J. Moon, Ronald Sabo, Theodore H. Wegner, James Beecher
The development of metrology for nanoparticles is a significant challenge. Cellulose nanocrystals (CNC) are one group of nanoparticles that have high potential economic value but present substantial challenges to the development of the measurement science

Review of Current Progress in Nanometrology with Helium Ions

September 19, 2011
Author(s)
Michael T. Postek, Andras Vladar, Bin Ming, Charles Archie
Scanning electron microscopy has been employed as an imaging and measurement tool for more than 50 years and it continues as a primary tool in many research and manufacturing facilities across the world. A new challenger to this work is the helium ion
