NMR Spectroscopy and Multiscale Modeling Shed Light on Ion-Solvent Interactions and Ion Pairing in Aqueous NaF Solutions

September 10, 2024
Author(s)
Gosia Musial, Demian Riccardi, Chris Suiter, Ethan Sontarp, Samantha Miller, Robert Lirette, Kyle Covington-Rehmeier, Avik Mahata, Chris Muzny, Angela Stelson, Kathleen Schwarz, Jason A. Widegren
The balance between ion solvation and ion pairing in aqueous solutions modulates chemical and physical processes from catalysis to protein folding. Yet, despite more than a century of investigation, quantitative determination of the distribution of ion

High-Pressure Vapor-Liquid Equilibrium Measurements of Methane + Water Mixtures by Nuclear Magnetic Resonance Spectroscopy

Samantha Miller, Chris Suiter, Mark O. McLinden, Jason A. Widegren, Nancy Levinger, Bret Windom, Michael Sartini
Accurate vapor-liquid equilibrium (VLE) data are required to predict the condensation of low-volatility components in natural gas pipelines. Here we apply 1H nuclear magnetic resonance (NMR) spectroscopy to measure the VLE of methane + water mixtures at

Dynamic vapor microextraction (DVME) is a headspace concentration method that can be used to collect ignitable liquid (IL) from fire debris onto chilled adsorbent capillaries. Unlike passive headspace concentration onto activated carbon strips (ACSs) that

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

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
