COMPOSITION DETERMINATION OF LOW-PRESSURE GAS-PHASE MIXTURES BY 1H NMR SPECTROSCOPY

March 4, 2019
Author(s)
Chris Suiter, Mark O. McLinden, Thomas J. Bruno, Jason A. Widegren
1H NMR spectroscopy was used to analyze vapor-phase mixtures of methane and propane at low to moderate pressures. The mixtures were prepared gravimetrically and had low uncertainty in their composition. The primary mixture used for this work had a methane

Evaluating smoldering behavior of fire-blocking barrier fabrics

January 29, 2015
Author(s)
Shonali Nazare, William M. Pitts, Szabolcs Matko, Rick D. Davis
This study reports on the smoldering propensity of commercially available barrier fabrics (BFs) in a small-scale mock-up configuration. Most BFs are smolder resistant when tested alone over a standard flexible polyurethane foam (FPUF). However, when
