Engineering faculty and students at the University of Colorado Boulder have produced the first experimental results showing that atomically thin graphene membranes with tiny pores can effectively and efficiently separate gas molecules through size-selective sieving.

The findings are a significant step toward the realization of more energy-efficient membranes for natural gas production and for reducing carbon dioxide emissions from power plant exhaust pipes.

Mechanical engineering professors Scott Bunch and John Pellegrino co-authored a paper in Nature Nanotechnology with graduate students Steven Koenig and Luda Wang detailing the experiments. The paper was published Oct. 7 in the journal’s online edition. (more…)

*Device could save time and money for oil/gas industry*

Mechanical engineering professor David Sinton and his research team have developed a process to analyze the behaviour of bitumen in reservoirs using a microfluidic chip, a tool commonly associated with the field of medical diagnostics. The process may reduce the cost and time of analyzing bitumen-gas interaction in heavy oil and bitumen reservoirs.

Sinton and post-doctoral researcher Hossein Fadaei are using the chips to examine the way highly pressurized carbon dioxide (CO₂) behaves when injected into bitumen, which is a type of petroleum. The new method, reported in the journal Energy & Fuels, could streamline the way fossil energy companies measure how gases move within heavier oils like bitumen. (more…)
