Autorenporträt

Nobuo Tanaka studied chemistry at Kyoto University, Japan. After his postdocs in the US at the Universities of Pennsylvania, Washington and Northeastern University, he came back to Kyoto, where he is Professor at the Institute of Technology. His research interests include development of chromatographic columns and stationary phases, separation of isotopes, isomers and environmental contaminants on solid surfaces. He is editor of Wileys Journal of Separation Science as well as others. He received several awards as the Environmental Award (1994), Award from the Society for Chromatographic Sciences (1998), the Jubilee Silver Medal of the UK Chromatographic Society (2002) and the Japan Society for Analytical Chemistry Award (2004).

Klaus K. Unger started his research career at the Technical University of Darmstadt, Germany, before he moved to the University of Mainz, Germany. He is one of the pioneers in the development of silica based materials for HPLC. He published many scientific papers as well as successful books.

Egidijus Machtejevas is postdoc in the research group of Klaus K. Unger and co-authored already many research papers.
