Prof. Mamdouh A. Ahmed from Department of Physics, Faculty of Science, Al Azhar University, Egypt, was invited to visit MEDC/DICP from 10th September to 1st October, 2014. During his visit, Prof. Mamdouh A. Ahmed presented a lecture with the title "Mössbauer spectroscopy of some fuel materials" at the laboratory of catalysis & new materials for aerospace. This lecture was presided over by Prof. Junhu Wang.

Prof. Mamdouh A. Ahmed has published over than 20 articles concerning the application of Mössbauer spectroscopy in coal characterization, desulphurization, pyrolysis as well as hot coal gas desulphurization. He is now starting an interesting project with Prof. Junhu Wang, MEDC-DICP, and it is dealing with the ultra-deep desulphurization via reactive adsorption.
