Ion Cyclotron Resonance Facility (ICR)

World-record 21 tesla ICR magnet. World-record 21 tesla ICR magnet.

This facility is charged with developing and exploiting the unique capabilities of Fourier Transform Ion Cyclotron Resonance (FT-ICR) mass spectrometry, and leads the world in instrument and technique development as well as novel applications of FT-ICR mass spectrometry.

The facility features directors for instrumentation, biological applications, environmental, petrochemical applications, and user services as well as a machinist, technician and numerous rotating postdocs who are available to collaborate and/or assist with projects.

The facility provides service operations for sample analysis that requires the ultrahigh resolution and high mass accuracy of FT-ICR. Research falls in the areas of biomolecular analysis, hydrogen-deuterium exchange and environmental and petrochemical analysis. The facility's four FT-ICR mass spectrometers feature high magnetic fields – including the world-record 21 tesla – and are compatible with multiple ionization and fragmentation techniques.

    Endohedral Metallofullerenes are Formed by Directed by Charge Transfer

    An understanding of the formation mechanism of endohedral metallofullerenes may pave the way towards targeted synthesis of these nanomaterials, which are attractive for use in biomedicine and renewable energy. Their bottom-up synthesis is investigated and charge transfer from the encapsulated metal to carbon cage is determined to play a key role in formation.
