Klaus Müllen
Klaus Müllen (born 2 January 1947) is a German chemist working in the fields of polymer chemistry, supramolecular chemistry and nanotechnology. He is known for the synthesis and exploration of the properties of graphene-like nanostructures and their potential applications in organic electronics. Early life and education Müllen was born in Cologne. He studied chemistry there and was awarded a PhD in 1971 under the supervision of Fabian Gerson at the University of Basel. He specialized in electron spin resonance (ESR) spectroscopy and his dissertation was on nuclear resonance and electron spin resonance spectroscopic studies on bridged annulenes. He completed post-doctoral studies at the ETH Zurich under Jean François Michel Oth (1926–2003) and received his habilitation in 1977 with a thesis on dynamic NMR spectroscopy and electrochemistry. Research career In 1979, he became professor of organic chemistry at the University of Cologne, and in 1983, he went to the Universit ...

Superphenalene
Superphenalene is a very large, synthetic polycyclic aromatic hydrocarbon (PAH) with chemical formula C96 H30. It can be formally considered to consist of three fused superbenzenes ( hexa-''peri''-hexabenzocoronene). It can be considered as an overlapping structure of three hexa-''peri''-hexabenzocoronenes arranged symmetrically around a center. These have also been known as building blocks of molecular electronics since 2004 as they form self-assembling columns and nanotubes. It and its hexa-''tert''-butyl derivative were first prepared in 1997, along with a collection of other very large PAHs. Due to the low solubility of these compounds, they could only be characterized by mass spectrometry when they were first synthesized, as neither NMR nor UV-Vis data could be collected. Properties Superphenalene has a planar geometry. With 540,000 mesomeric boundary structures, it has significantly more than hexabenzocoronene (250), supernaphthalene (16,100) and also buckminste ...

Academia Europaea
The Academia Europaea is a pan-European Academy of humanities, letters, law, and sciences. The Academia was founded in 1988 as a functioning Europe-wide Academy that encompasses all fields of scholarly inquiry. It acts as co-ordinator of European interests in national research agencies. History The concept of a 'European Academy of Sciences' was raised at a meeting in Paris of the European Ministers of Science in 1985. The initiative was taken by the Royal Society (United Kingdom) which resulted in a meeting in London in June 1986 of Arnold Burgen (United Kingdom), Hubert Curien (France), Umberto Colombo (Italy), David Magnusson (Sweden), Eugen Seibold (Germany) and Ruurd van Lieshout (the Netherlands) – who agreed to the need for a new body. The meeting also included Brian Flowers and John Kendrew.

Karlsruhe Institute Of Technology
The Karlsruhe Institute of Technology (KIT; ) is both a German public research university in Karlsruhe, Baden-Württemberg, and a research center of the Helmholtz Association. KIT was created in 2009 when the University of Karlsruhe (), founded in 1825 as a public research university and also known as the "Fridericiana", merged with the Karlsruhe Research Center (), which had originally been established in 1956 as a national nuclear research center (, or KfK). KIT is thus the first and only institution in Germany to overcome the division of the German scientific and research landscape into academic and non-academic institutions in the form of a merger of two different types of institutions. KIT is a member of the TU9, an incorporated society of the largest and most notable German institutes of technology. As part of the German Universities Excellence Initiative KIT was one of three universities which were awarded excellence status in 2006. In the following "German Excellence ...
