Prof.Dr.ir. Gustaaf Schoukens was professor of polymer technology at the Ghent University (Belgium), faculty of Engineering, retired since October 1, 2014. He received his degree in Chemical Engineering from the K.U. Leuven (Belgium) in 1971 where he also obtained his Ph.D. in 1978. The subject of his Ph.D. research was "Non-linear viscoelastic behavior of dispersions". This subject has a renewed interest due to the presence of nanoparticles in the air (pollution) and even in blood and longs and their possibility to form gel-like structures. He worked as senior researcher from 1978 till 2004 in the private industry (Solvay; Central Research Laboratory) in the field of polymerization and polymer processing. In 1994 he obtained the part-time position of lecturer at the Ghent University, teaching "polymer processing". In 2004 he obtained the fulltime position of professor at the Ghent University teaching all courses concerning polymer technology, including processing and polymerization processes. He is also involved in the courses concerning "environment and sustainable development" in general and teaching the course of "rational use of materials" in particular.

Karl-Heinz Gresslehner was born on 27.03.1948 in Linz / Austria. After graduating from secondary school and higher technical educational school he studied Physics at the Technical University in Graz / Austria with a focus on electrodynamics. He finished his diploma in 1976 and the title of the master thesis was 'Theory of bending at the elliptical cylinder'. After that he started his dissertation at the Johannes Kepler University in Linz / Austria with a focus on experimental and theoretical physics on IV-VI compounds. He finished his PhD in 1981 and the title of the doctoral thesis was 'Electronic structure of defects in ion-implanted Pb(x)Sn(1-x)Te thin films'. More than 10 years he was working in the industry (semiconductor industry, environmental protection at the state government Upper Austria) and 24 years as a teacher at a school for higher technical education (HTL). Since 2016 he is a Professor at the University of Applied Sciences in Upper Austria teaching technical subjects such as measurement technique, physics, electrodynamics, quantum mechanics, mathematical methods for physicists, etc. and is the head of the research group Thermoelectricity.
