Science

On these pages I want to introduce details about my scientific work.

Career

In 1999 I started to study Chemistry at the Technische Universität Darmstadt (TUD). In the following years my interest for Physical Chemistry and particularly for magnetic resonance spectroscopy grew stronger. I graduated in February 2005 (German diploma) on the preparation and EPR characterization of endohedrally and paramagnetically doped fullerene peapods N@C60@SWNT and N@C70@SWNT (Diploma thesis in German language: "Präparation und EPR-Untersuchung von endohedral paramagnetisch dotierten Fulleren-Peapods N@C60@SWNT und N@C70@SWNT"). The diploma studies have been carried out in the group of Prof. Dr. Klaus-Peter Dinse at the Eduard-Zintl-Institut für Anorganische und Physikalische Chemie at TUD.

I started my doctoral studies in the same group in March 2005. After three years of intense research I was able to submit my thesis "Electromagnetic properties of single-walled carbon nanotubes investigated by microwave absorption" and graduate as Ph.D. (German Dr.-Ing.) in June 2008.

Since January 2009 I am working as a postdoctoral fellow at the Francis Bitter Magnet Laboratory at Massachusetts Institute of Technology. There I am working on time-domain (pulsed) dynamic nuclear polarization (DNP). The funding for this stay is generously provided by the Deutsche Forschungsgemeinschaft (DFG) within a research fellowship (grant CO802/1-1).

Topics of research

During my studies I examined single-walled carbon nanotubes (SWNT) and the related intercalation compounds with fullerenes (i.e., the so-called peapods) using electron paramagnetic resonance (EPR) spectroscopy [1-9]. I also synthesized the peapod material using endohedral fullerenes N@C60 und N@C70 as paramagnetic spin-probes [1-3,6,7]. Besides EPR, I also applied different analytical methods, for example non-resonant microwave absorption [4-6,8,9], high-resolution transmission electron microscopy (HR-TEM), thermogravimetry (TG), differential thermal analysis (DTA), high-perfomance liquid chromatography (HPLC), and magnetometry [6].

I also contributed to the solution of several actual problems in Chemistry by applying modern EPR. These problems include the dissolving of the structure of Cu(II)-hemicarcerand compounds [10], the investigation of the electronic and spin properties of a Co(II)-tetraphenylporphyrin-C60 diade and their derivatives [11], and also theoretical work regarding the analysis of 14N-HYSCORE spectra [12].
