Helge Willner

from Wikipedia, the free encyclopedia

Helge Willner (born March 7, 1947 in Hamm ) is a German chemist . He is emeritus professor for inorganic chemistry at the University of Wuppertal , North Rhine-Westphalia .

Life

From 1963 to 1966, Helge Willner did an apprenticeship as a chemical laboratory assistant at Schering AG in Bergkamen . He then attended the state engineering school in Essen and graduated from university in 1969 . Helge Willner studied chemistry from 1969 to 1971 at the Westfälische-Wilhelms-Universität in Münster , where he then worked with H.-J. Becher did his doctorate on matrix influences on the internal vibrations of terahedral anions and molecules . He then worked as a research assistant at the Ruhr University Bochum at A. Haas and completed his habilitation in 1981 at the Ruhr University Bochum on binary sulfur and selenium fluorides in low oxidation states . In 1982 he was appointed to the University of Hanover (C3-Professorship for Inorganic Chemistry), in 1998 he moved to the University of Duisburg as the successor to P. Sartori (C4-Professorship for Inorganic Chemistry) and from 2003 was at the University of Wuppertal as the successor to H. . Citizens active. Willner was awarded the “Dr. Luis Federico Leloir ”award and in 2013 retired .

Scientific work

Willner's main research interests were synthetic chemistry , molecular spectroscopy and matrix isolation.

Young talent was also important to Helge Willner. His experimental lectures at the Children's Research Days at the University of Wuppertal were legendary. In addition, between 2005 and 2009 he and Prof. Per Jensen participated in the Marie Curie Research Training Network , a European Union network for young chemists. Helge Willner was strongly committed to the international exchange of scientists and students. For 20 years he worked closely with Friedhelm Aubke ( Canada ) and with colleagues at the universities of La Plata and Córdoba ( Argentina ), initiated and organized an exchange of doctoral students, young scientists and professors between the participating institutes and supported communication with numerous scientific projects between cultures. On the Argentine side, the cooperation was u. a. financed by the National Council of Sciences (CONICET), on the German side by the German Academic Exchange Service (DAAD), the Alexander von Humboldt Foundation and the VW Foundation .
