Jörg Kärger (born 3 October 1943) is a German physicist.

Life and work

Jörg Kärger was born in Erfurt. After attending school in Erfurt and Leipzig, he studied physics at the University of Leipzig, whose member he remained in the subsequent years, interrupted by guest stays in Prague, Leningrad, Moscow, Paris and Fredericton/Canada. His doctorate in 1970 with the dissertation "The diffusion of water at 13X zeolites: investigated by the method of nuclear magnetic resonance with the aid of pulsed field gradients" under the supervision of Harry Pfeifer was followed in 1978 by his doctorate B (1991 with conversion to habilitation) as well as the appointment to an extraordinary professorship in 1989 and a full professorship for experimental physics / interface physics in 1994.

His scientific career was determined by his work on the use of NMR spectroscopy to measure molecular diffusion in nanoporous materials (zeolites), which he had already begun during his doctorate. After his measurements, existing ideas had to be corrected by orders of magnitude, which led to a paradigm shift in the understanding of molecular mass transport in such systems. The mechanism of two-range diffusion he applied became a widely used model for NMR diffusion measurements in complex systems, including their use for magnetic resonance imaging. His monographs Diffusion in Zeolites and Other Microporous Solids (Wiley, 1992, together with D. M. Ruthven)[1] and Diffusion in Nanoporous Materials (together with D. M. Ruthven and D. N. Theodorou) became core literature in sorption research, i.e. in the investigation of the behavior of molecules in interaction with interfaces. His work was recognized with the award of the Gustav Hertz Prize of the GDR Physical Society (1978, together with Harry Pfeifer), the Breck Award of the International Zeolite Association (1986, together with Harry Pfeifer, Dieter Freude and Martin Bülow) and the Max Planck Research Award (1993, together with Douglas M. Ruthven). He is the author of over 500 papers in periodicals, author/editor of 10 books.

Together with Paul Heitjans, he initiated the Diffusion Fundamentals conference series, which is devoted to the phenomena of random movement and propagation in their entirety.[2] The objects considered can thus be of a material or immaterial nature and range from atoms and molecules as the traditional objects of diffusion research to new species in the animal and plant world and new words in our vocabulary. Since the 6th conference 2015 in Dresden the conference series with the accompanying Diffusion-Fundamentals-Online-Journal[3] has been under the auspices of the Saxon Academy of Sciences and Humanities in Leipzig.

The Dresden conference gave rise to the edition of a book on "Diffusive Spreading in Nature, Technology and Society", for which he, together with Armin Bunde, Jürgen Caro and Gero Vogl, was awarded the Literature Prize of the Fonds der Chemischen Industrie in 2019.[4]

In 2020 he and Jürgen Caro, his first doctoral student, received the ENI award in the “Advanced Environmental Solutions” category for their work, which led to the development of micro-imaging methods for the observation of diffusive molecular flows in nanoporous materials.[5] In 2022, Jörg Kärger was awarded the Otto Stern Prize by the Magnetic Resonance Division of the German Chemical Society, in recognition of his fundamental contributions to the application of nuclear magnetic resonance (NMR) spectroscopy.

In 2005, Kärger was awarded the Theodor Litt Prize of the University of Leipzig for his merits in teaching.[6] His Sunday lectures at the Faculty of Physics and Earth Sciences with up to 500 listeners had a special impact on the media. In one of them, with coordinated bicycle bells, the lecture visitors formed the world's largest bicycle bell orchestra for entry in the Guinness Book of World Records.[7]

Jörg Kärger has been married to the dentist Birge Kärger, née Koch, since 1971. The marriage produced four children (Sebastian 1976, Wieland and Luise 1978 and Philipp 1981).
