Time-Resolved Infrared Spectroscopy of an [FeFe]-Hydrogenase Model Compound

March 26, 2012
Author(s)
Edwin J. Heilweil
Naturally occurring hydrogenases catalyze the reaction of H+ to form H2 gas. To develop a hydrogen source that is not reliant on fossil fuels, synthetic [FeFe]-hydrogenase model species are being studied. These compounds have a wing-like structure with a

In Situ Raman Monitoring of Ring-Opening Copolymerizations

March 25, 2012
Author(s)
Matthew T. Hunley, Santanu S. Kundu, Peter M. Johnson, Kathryn Beers
Recent advances in enzyme, metal, and organic catalysts have enabled the development of advanced functional polymers from cyclic ester and cyclic carbonate monomers. In this work, we present an in situ technique to monitor ring-opening polymerization using

Flexible polyurethane foam with well characterized and reproducible smoldering

March 24, 2012
Author(s)
Mauro Zammarano, Szabolcs Matko, Rick D. Davis, Roland H. Kraemer
Smoldering is a self-sustaining heterogeneous oxidation reaction that induces a slow, low temperature, flameless combustion.1 Flexible polyurethane foams (PUF) are particularly prone to smoldering due to their high air permeability and low density. In this

Modeling the effects of acid amplifiers on photoresist stochastics

March 23, 2012
Author(s)
Gregg M. Gallatin, Patrick Naulleau, Robert Brainard
The tradeoff between Resolution, Line Edge Roughness (LER) and Sensitivity, the so called RLS tradeoff, continues to be a difficult challenge, especially for EUV lithography. Acid amplifiers have recently been proposed as a method to improve upon the

2011 Solutions in Perception Challenge Performance Metrics and Results

March 22, 2012
Author(s)
Jeremy Marvel, Tsai H. Hong, Elena R. Messina
The 2011 Solutions in Perception Challenge (SPC) presented an international collection of teams with the opportunity to develop algorithms that could positively identify and accurately locate in space an arbitrary collection of artifacts. Researchers at

A Keyed Sponge Construction with Pseudorandomness in the Standard Model

March 22, 2012
Author(s)
Donghoon Chang, Morris Dworkin, Seokhie Hong, John M. Kelsey, Mridul Nandi
The sponge construction, designed by Bertoni, Daemen, Peeters, and Asscheis, is the framework for hash functions such as Keccak, PHOTON, Quark, and spongent. The designers give a keyed sponge construction by prepending the message with key and prove a

An IEEE 1588 Performance Testing Dashboard for Power Industry Requirements

March 22, 2012
Author(s)
Julien M. Amelot, YaShian Li-Baboud, Clement Vasseur, Jeffrey Fletcher, Dhananjay Anand, James Moyne
The numerous time synchronization performance requirements in the Smart Grid entails the need for a set of common metrics and test methods to verify the ability of the network system and its components to meet the power industry�s accuracy, reliability and
