“Magnetism, as you recall from physics class, is a powerful force that causes certain items to be attracted to refrigerators.” -- Dave Barry (American Writer and Humorist, b.1947)
So many technologies, so little time … Magnetic resonance is one of the technologies being used to explore the desulfurization problem. Accordingly, Montana State University’s Magnetic Resonance Lab (http://www.coe.montana.edu/mrm/) is one of the organizations worth visiting from time to time. Here is some information from its Web …

Ceramics and Foams
These modern materials are invaluable to the alternative energy industry, food industry and medical industry. Our ability to increase the range of application of fuel-cells, or design next generation filtration systems for industry and medicine, depends on our ability to improve our understanding of transport in the complex structures of designed porous media such as new ceramics and foams.
Porous Media
The underlying physics of transport in porous media is relevant to the aforementioned ceramics and foams as well as a plethora of other applications like industrial packed bed chemical reactors, transport in gels and tissues for drug delivery, storage of supercritical CO2 in natural formations and in sub-surface transport of environmental contaminants in the earth’s subsurface. Many porous media of interest have structures that generate complex dynamics which can be modeled by fractal and percolation theory concepts. MR methods provide unique data for scale dependent transport in porous media since most are opaque and not amenable to analysis by other methods. Modeling the impact on transport dynamics of biological and chemical reactions in porous media presents a significant challenge for design of environmental remediation strategies and new materials.

Sarah Codd is co-director of the Magnetic Resonance Lab and an Associate Professor in the Department of Mechanical and Industrial Engineering at Montana State University. Her research focuses on technique development, spatially resolved studies of gas in ceramics, flow and diffusion studies in porous media, and investigation of fluid dynamics in hydrogels, biofilms, cellular suspensions and polymer electrolyte membranes.

Joe Seymour is co-director of the Magnetic Resonance Lab and an Associate Professor in the Department of Chemical and Biological Engineering at Montana State University. His primary area of research interest is in transport imaging using MRM. Prior and future research includes laboratory and field studies of transport phenomena using MRM's ability to measure both coherent motion, or velocity, and random motion, or diffusion. During a postdoctoral stay in New Zealand with Prof. Paul Callaghan research was conducted in Antarctica in 1995 and 1997 to study the structure of sea ice using NMR in the Earth's magnetic field. The opportunity to combine science, outdoor adventure and the history of Antarctic exploration, was a unique and rewarding experience. Here is a photo (lower right) taken at Cape Evans on McMurdo Sound by the hut used in Robert Falcon Scott's ill fated British Antarctic Expedition of 1910-1913, the Terra Nova Expedition, during which Scott and his companions died on their return from the South Pole.
