Diffusive Spreading in Nature, Technology and Society

Armin Bunde studied Physics at the universities in Giessen and Stuttgart (PhD 1974). After postdoc periods in Saarbrücken, Antwerp, and Konstanz he was awarded a Heisenberg fellowship in 1983. In 1984 he received the Carl-Wagner prize.  After extended research stays in Boston, Paris, and Ramat-Gan he became professor for Theoretical Physics at Hamburg University in 1987 and full chair of Theoretical  Physics  at Giessen University in 1993. His research activities have been dedicated to many facets of  interdisciplinary research, including diffusion in disordered materials, long-range correlations in nature, extremes in financial markets, and climate variability, and he co-authored several books on these topics.
Jürgen Caro graduated in Chemistry at Leipzig University (PhD 1977, supervised by Jörg Kärger, Habilitation 1992). After PhD he joined the Academy of Sciences of GDR in Berlin-Adlershof. In 2001 he became professor of PhysicalChemistry at Leibniz University Hannover working in porous materials as membrane, catalyst and adsorbent. He is author of about 400 publications and 43 patents. In 2013 he got together with M. Tsapatsis the Donald W. Breck Award, in the same year the Ostwald Medal of the Saxon Academy of Sciences and in 2020 the Eni Award for “Advanced Environmental Solutions” together with J. Kärger. In 2016 Caro became Corresponding Member of the Saxon Academy of Sciences.

Christian Chmelik graduated in Physics at Leipzig University (PhD 2008, supervised by Jörg Kärger). As part of his dissertation, he established IR micro-imaging as a new method for diffusion measurement in nanoporous materials. As postdoc he continued to chair the development of microimaging methods for diffusion measurements. He is an editor of the online journal ‘‘Diffusion Fundamentals’’ and chaired the eponymous conference in 2009 (Athens) and in 2015 (Dresden). Since 2014 he is member of the structure-related commission “Spreading in Nature, Technology and Society” of the Saxonian Academy of Sciences. He is author of more than 80 publications, two edited books and several book chapters.

Jörg Kärger is emeritus professor of physics at Leipzig University. His research focuses on the development of new experimental techniques for studying diffusion in nanoporous materials. He has (co)-authored several books on the topics of diffusion and nanoporous materials and, together with Paul Heitjans, established the online journal and conference series Diffusion Fundamentals. His work has been widely recognized via e.g. the Donald W. Breck Award for zeolite research, the Max Planck Research Prize, and election to the Saxon Academy of Sciences. He holds an entry in the Guinness book of records for the largest orchestra of bicycle bells, awarded during the Physics Sunday Lectures at Leipzig University.

Gero Vogl received his habilitation from the Physik-Department of Technische Universität München, then moved to Freie Universität Berlin as professor of experimental physics. From 1985 till 2009 he was full professor of physics at Universität Wien and from 1999 till 2001 acted as chairman of the Department of Structural Research at the Hahn-Meitner-Institut Berlin. His scientific interests were centered on the dynamics of solid matter. He introduced several new methods based on the application of nuclear physics to materials science. After 2005 Vogl devoted much of his capacity to interdisciplinary research in the field of spread and diffusion publishing some booklets on that subject.
