High-Throughput Measurements of Polymer Adhesion and Mechanical Properties

September 1, 2003
Author(s)
Christopher Stafford, Aaron M. Forster, C Harrison, Cher H. Davis, Eric J. Amis, Alamgir Karim
Polymer adhesion is important to numerous technologies including electronic packaging, coatings and paints, biomedical implants, and pressure-sensitive adhesives. The challenge is to understand the fundamental driving forces for the development of adhesive

High-Throughput Milli-Fluidic Platform for Polymer Formulations

September 1, 2003
Author(s)
Kathryn L. Beers, J Cabral, H J. Walls, Alamgir Karim, Eric J. Amis, C Harrison
Rapid prototyping of microfluidic handling devices has gained in popularity due to the ability to quickly test and modify new design features several times in one day.8-13 While elastomer-based methods have dominated the literature and are remarkably well

Immersive Virtual Reality for Steel Structures

September 1, 2003
Author(s)
Robert R. Lipman
This paper describes an immersive virtual reality system for steel structures. The system integrates standard models and formats for representing structural steel and three-dimensional graphic objects with a framework for device independent virtual

Influence of analysis Algorithms on the Value of Distorted Step Height Data

September 1, 2003
Author(s)
Ndubuisi G. Orji, Jayaraman Raja, Son H. Bui, Theodore V. Vorburger
One of the most important aspects of step height evaluation are the analysis algorithms used. There algorithms assume that the profiles and images being analyzed are ideal, but real step profiles are not ideal and the analysis algorithms can influence the

Influence of Roughness on Wear Transition in Glass-Infiltrated Alumina

September 1, 2003
Author(s)
Sergei Kalinin, S Jahanmir
The wear behavior of glass-infiltrated alumina was evaluated in sliding against a high purity alumina in water using a pin on disk tribometer. Three disk surface roughness values were used, i.e., 14 nm, 146 nm and 649 nm Ra. The wear rate of both the

Intelligent Systems for Urban Search and Rescue: Challenges and Lessons Learned

September 1, 2003
Author(s)
Adam S. Jacoff, Elena R. Messina, Brian A. Weiss
Urban search and rescue (USAR) is one of the most dangerous and time-critical non-wartime activities. Researchers have been developing hardware and software to enable robots to perform some search and rescue functions so as to minimize the exposure of

Interdiffusion in Polystyrene and End-Functional Polystyrene Thin Films Near a Solid Surface

September 1, 2003
Author(s)
C M. Wang, Vivek Prabhu, Christopher Soles, B D. Vogt, Wen-Li Wu, Eric K. Lin, Sushil K. Satija
Polymer interdiffusion near the polymer/solid interface is studied using neutron reflectometry. Bilayers of hydrogenated polystyrene (hPS) and deuterated polystyrene (dPS) or hydrogenated dicarboxy terminated polystyrene (hPS(COOH)2) and dPS are prepared

Knowledge Intensive Collaborative Decision Support for Design Process

September 1, 2003
Author(s)
XuanFang Zha, Ram D. Sriram, W F. Lu
Engineering design is essentially a collaborative decision making process that requires rigorous evaluation, comparison and selection of design alternatives and optimization from a global perspective on the basis of different classes of design criteria

Measurement of Gate-Oxide Film Thickness by X-ray Photoelectron Spectroscopy

September 1, 2003
Author(s)
Cedric J. Powell, Aleksander Jablonski
X-Ray Photoelectron Spectroscopy (XPS) is being used to an increasing extent for the characterization of new gate-oxide materials, particularly for the determination of film composition, uniformity, and thickness. A key parameter for film-thickness

NEXAFS Measurements of the Surface Chemistry of Chemically Amplified Photoresists

September 1, 2003
Author(s)
E Jablonski, M Angelopoulos, H Ito, Joseph~undefined~undefined~undefined~undefined~undefined Lenhart, S Sambasivan, Daniel A. Fischer, Ronald L. Jones, Eric K. Lin, Wen-Li Wu, D L. Goldfarb, K Temple
Near edge x-ray absorption fine structure (NEXAFS) spectroscopy was used to quantify the surface composition profile (top 1 nm to 6 nm) of model chemically amplified photoresists with various photo-acid generators. These materials are prone to interfacial

NIST 2003 Language Recognition Evaluation

September 1, 2003
Author(s)
Alvin F. Martin, Mark A. Przybocki
The 2003 NIST Language Recognition Evaluation was very similar to the last such NIST evaluation in 1996. It was intended to establish a new baseline of current performance capability for language recognition of conversational telephone speech and to lay

Novel Chemical Detection Strategies for TCE and PCE

September 1, 2003
Author(s)
A C. Pipino
Novel applications of cavity ring-down spectroscopy (CRDS) to chemical detection are described. Using a linear optical resonator with an intra-cavity double-Brewster-window flow cell, CRDS is employed to probe the optical response to adsorption of the

Optical Manipulation and Fusion of Liposomes as Microreactors

September 1, 2003
Author(s)
S Kulin, N Kishore, Kristian Helmerson, Laurie E. Locascio
We present an all optical method to manipulate and fuse giant liposomes, typically 10 nm in diameter. Optical tweezers are used to trap two individual liposomes, which are then brought into contact. A single pulse of ultraviolet laser light focused on the
