Preface The year 2006 of the Department of Materials- and Geo-Sciences was characterized by a stabilisation of the Geo-Sciences and a shift of severe structural changes to the Institute of Materials Science. In addition, our Dean Prof. Heinz von Seggern resigned due to health problems on March 31 and was succeeded by Prof. W. Jaegermann. We all would like to thank Prof. v. Seggern for his efforts. Finally, the target agreement was signed mid of 2006; however some different opinions on the future of the departments were still not settled at this time. The development of students’ and graduate numbers for Materials- and Geo-Science are shown in Fig. 1. Fig. 1 Number of graduates (diplomas and doctorates) in Materials- and Geo-Sciences at Darmstadt University of Technology over the last 7 years After the appointment of Prof. Hans-Joachim Kleebe in January 2006 as head of the Geomaterials Group following Prof. Wolfgang Müller, all chairs of the Institute of Geo- Science are now assigned. The new crew has defined new directions in research and education at the TU Darmstadt. More information about the achievements of the year 2006 are given below. In Materials Science the reoccupation of professorships substituting the first founding generation after retirement or appointment to other institutions is still a major challenge. Hartmut Fuess who was the first professor of the newly founded Department of Materials Science in 1989 was retired in Oct. 2006. Prof. Dr. Dr. h. c. Fuess was head of the Structural Research Division and succeeded to built-up a nationally and internationally - 4 -
highly recognized research lab on structural research. Especially, the powder diffraction facilities located at national laboratories in Hamburg and Munich (DESY and FRM II) were used in cooperation by many guests from Germany and other institutions abroad. In addition, Prof. Fuess served for several years as dean of the Department of Materials Science and after unification with Geoscience of the Department of Materials- and Geo- Sciences. He has strongly contributed to the excellent scientific profile of the department by his outstanding scientific contributions, but also by his visionary ideas and admirable management qualities. We will have to struggle hard to find qualified successors. Fortunately Prof. Fuess has agreed to continue to lead his research group for the next future until a successor has joined the department. Therefore we still profit from his experience and knowledge. In September 2006 Prof. Jürgen Eckert followed an offer of the Institute of for Solid State and Materials Research in Dresden as head of the Department of Complex Solids. We would like to thank him for his contributions in Darmstadt and wish all the best for his new appointment. Some of the very qualified junior scientist who have obtained their habilitation at TU Darmstadt have also left the department: Dr. Doru Lupascu moved to TU Dresden where he was appointed as professor of functional ceramics; Dr. Roland Schmechel was appointed as a professor in electrical engineering at University of Duisburg-Essen on nanostructuring techniques (unfortunately we were not successful to keep him at our institute with a combined effort of TUD and FZK); Dr. Helmut Ehrenberg has moved to the IFW Dresden together with Prof. Eckert. We want to thank our younger colleagues for their valuable contributions to the success of the department and hope for similarly qualified Post-Docs in the future to secure the high level of our scientific and educational efforts. A large fraction of time was devoted during 2006 to join the national excellence initiative with the final application of a cluster of excellence MECAD aiming at multi-functional materials based on composites for advanced devices. During the first months of the year regular extended discussions on the scientific content and organisational and structural demands were held together with our colleagues from the departments of chemistry, physics, biology, electrical engineering and mechanical engineering. Finally, thanks to the perfect management of Prof. J. Rödel a very promising research proposal was submitted, which unfortunately did not receive funding at the end. However, as we have obtained encouraging referee reports on the scientific content of our research proposal we intend to follow this interesting topic as one of our maior scientific subjects of the future. Fortunately, another major research program in Materials Science, the collaborative research centre on “Electric fatigue in functional materials”, was positively evaluated in Oct. 2006 and will continue in its second funding period. This activity is also directed by Prof. Rödel and a special thanks goes also to Dr. Kinski who provided substantial support in preparing the proposal consisting of more than 750 printed pages. The proposal was rated close to excellent by the referees and will be continued nearly without any deductions. In result, a strong support of the Materials Science research activities was successfully realized, which will help to keep us in action for the next four years. The annual event “Materialwissenschaftlicher Tag” in 2006 was devoted to the 60 th anniversary of Prof. Rauh. At this occasion the research activities in Theoretical Materials Science at our department were presented. Since Prof. Rauh is not only interested in theoretical physics, but also in classical music, well balanced contributions of talks, posters and musical performances of the Rauh family stimulated inspiring discussions on the - 5 -
