Look Who's at the Lab: Klaus-Peter Dinse (June 2009)
In Look Who's at the Lab, we profile some of the hundreds of scientists who visit our lab every year.
Klaus-Peter Dinse in the EMR lab.
Title: Professor, Free University of Berlin
Mag Lab user since: 2003
Number of visits to the lab: 6
Dates of most recent experiment:
June 1-12, 2009
Distance traveled: 4,829 miles / 7,757 km (Berlin to Tallahassee)
Research Interests:
"I am interested in a wide variety of nanoscopic materials such as buckyballs, nanotubes and catalysts. These compounds are used as 'spies' exploring the immediate neighborhood, used as electrical conductors, or are actively involved in chemical reactions, like the hydrogenation of fossil fuels."

Title: High-frequency EPR investigation of vanadium supported on SBA-15 and gamma-alumina
Other Participants: Hans van Tol and Andrew Ozarowski, National High Magnetic Field Laboratory.
Synopsis: "Carbon nanotubes have become quite popular because of their unique mechanical and electrical properties, suggesting their use as building material for a 'space elevator' and as superconducting leads for the next generation of electronic devices. Both features are controlled by the presence of defects, which will spoil the one-dimensional properties that are essential for these properties. The use of Electron Paramagnetic Resonance (EPR) under conditions of the extreme magnetic fields available at the Mag Lab is a powerful method not only for the detection of these defects, but also essential for their verification. In catalysis the active sites participate in electron storage and release during the chemical reaction. As a result, the magnetic ('spin') properties change. The lab's high magnetic fields are extremely useful for monitoring these anticipated changes."
Facility: EMR Facility, Tallahassee.
Equipment: Superconducting magnets
Techniques: High frequency EMR spectrometers working in continuous and pulsed mode, using frequencies up to 400 GHz.
