Magnetic Nanoparticles

There is a great technological interest in the synthesis of maghemite nano-composites due to their magnetic and catalytic properties. These materials are expected to find applications in magnetic recording, magnetic refrigeration, magneto-optical solid devices, magnetic resonance imaging. The group has been conducting research on magnetic materials and they intend to expand their research activities in the coming years. The group has a good international connections and a strong interaction with the other Turkish universities.

Prof. Dr. Macit Ozenbas has Ph.D. in Metallurgical Engineering from METU (1981). He received Max Planck Gesellschaft Scholarship and worked at Max-Planck-Institute für Metallforschung in Germany in 1985-1987. He received NATO Research Fellowship and worked in Princeton University in USA in 1997-1998 as visiting scientist. He visited the same place in 1999, 2001, and 2003 for short time stays. He conducted 1 Ph,D, and 17 M.Sc. thesis. He is currently leading 4 M.Sc. and 2 Ph.D. students. Three of these students are working on a thesis which is directly related to nanotechnology. He participated in the COST 514 project on ferroelectric thin films in 1994-1998. He was the Turkish representative in the management committee of this action. He has also conducted a USA-NSF project on micropatterning of ferroelectric thin films and size effect. He was one of the organizers of the Chemical Engineering Conference for Collaborative Research in Eastern Mediterranean in 2001, and National Workshop on Nanotechnology in 2002. He was the Scientific Committee member for the 8th European Ceramic Society Meeting held in Istanbul in 2003.

Prof. Dr. Mürvet Volkan has Ph.D. in Chemistry from METU (1985). She received British Council Scholarship and worked at University of Manchester-Department of Instrumentation and Analytical Science (UMIST) England in 1981. She went to University of Southampton, England in 1983 to perform part of her Ph.D studies. She was a visiting scientist at University of California Davis, USA in 1988-1989. She received NATO Research Fellowship in 1997 and carried out research for 2 years at Oak Ridge National Laboratory , USA. She conducted 10 M.Sc. thesis. She was one of the organizers of the Colloquium Spectroscopicum Internationale XXXI, Ankara, Turkey, September 5-10, 1999. She had participated in FP6-2002-NMP-1 projects acronymed as OPTOSENSORS. Although the project proposal didn't reach the minimum thresholds, it was a suitable experience in the joint work with several European partners.
