Ravikiran Attota, Michael T. Stocker, Richard M. Silver, Nathanael A. Heckert, Hui Zhou, Richard J. Kasica, Lei Chen, Ronald G. Dixson, Ndubuisi G. Orji, Bryan M. Barnes, Peter Lipscomb
In this paper we present overlay measurement techniques that use small overlay targets for advanced semiconductor applications. We employ two different optical methods to measure overlay using modified conventional optical microscope platforms. They are

Thermal Decomposition Kinetics of the Aviation Turbine Fuel Jet-A

July 2, 2008
Author(s)
Jason A. Widegren, Thomas J. Bruno
As part of a larger-scale thermophysical and transport property measurement project, the global decomposition kinetics of the aviation turbine fuel Jet-A was investigated. Decomposition reactions were performed at 375, 400, 425, and 450 °C in stainless

Properties of a 50/50 Mixture of Jet-A + S-8

Thomas J. Bruno, Arno D. Laesecke, Stephanie L. Outcalt, Hans-Dieter Seelig, Beverly L. Smith
This report describes measurement efforts performed on the mixture of aviation fuels: Jet-A + S-8*. The primary mixture is a 50/50 (vol/vol) combination of the two fuels. Measurements include chemical analysis, density, viscosity, speed of sound and vapor

Development of an Experimental Database and Kinetic Models for Surrogate Jet Fuels

March 1, 2007

M Colket, T Edwards, S Williams, N Cernansky, D L. Miller, Fokion N. Egolfopoulos, P Linstedt, Ram Seshadri, F L. Dryer, C K. Law, Daniel G. Friend, David Lenhert, Heinz Pitsch, A Sarofim, M Smooke, Wing Tsang
The engineering and scientific community ha been searching for the identification of surrogate fuels that can reasonably represent the performance and emissions behavior of jet fuels (e.g. Jet A and JP-8) in engines. Many proposals exist in the literature
