Road asphalt is made from aggregate (rocks) mixed with a "binder” from the residue remaining after extraction of gasoline and oils from petroleum crude oil. Until recently, this binder was thought to be chemically unreactive. Maglab scientists subjected a thin film of asphalt binder to simulated sunlight in the laboratory and used ultrahigh resolution mass spectrometry to reveal thousands of new, water-soluble chemicals that could be released into the environment by rainfall.

MagLab researchers use 21 tesla ion cyclotron resonance (ICR) mass spectrometry to identify the best way to produce carbon fibers from petroleum waste products. The best carbon fibers are made from molecules that don’t contain sulfur or large polycyclic aromatic hydrocarbon structures, and these bad molecules can be converted to better precursors by mild thermal treatment.
Wildfires change the chemical composition of molecules in soil, and only the 21T FT-ICR mass spectrometer can assess the molecular composition to understand the long term impact of wildfires on soil chemistry.
These include biological, environmental and petrochemical applications as well as analytical method development for FT-ICR mass spectrometry.
Combining high-field NMR with infrared microscopy, scientists learned more about how gas diffuses in a novel class of molecular sieves that could one day be used for gas separation.
For the first time, NMR diffusion measurements have been successfully used in a metallic catalyst, examining gas exchange rates in nanoporous gold. These findings helped determine an optimal process for efficiently catalyzing CO to CO2 and may help make the catalyst more effective for industrial applications that reduce waste from power plants and refineries.
Solid oxide fuel cells generate clean energy by oxidizing green fuels like hydrogen and reducing atmospheric oxygen, without recharging or emissions that contribute to climate change. They use a fast ion conductor electrolyte to move oxygen ions between electrodes, converting chemical energy to power. Our research uses 71Ga solid-state NMR spectroscopy on the highest-field magnet in the world to study the numbers of oxygen ions near gallium atoms – this will inform the design of better electrolyte materials for fuel cells.
