Jan Reedijk Jan Reedijk is emeritus Professor of Chemistry at Leiden University. He has authored and co-authored over 1100 research papers in molecular inorganic chemistry areas, like coordination chemistry, biomimetic chemistry, anticancer metal compounds and homogeneous catalysis. His work has been honored by a Max Planck Award, and a Royal Knighthood to the order of the Dutch Lion. He is also an elected Member of the Royal Netherland Academy of Sciences, the Academia Europaea and the Finnish Academy of Sciences. In 2023 he received a doctorate honoris cause from the Nicolaus Copernicus University in Torun, Poland. He has been a founding editor of the European Journal of Inorganic Chemistry and served on the editorial board of a number of scientific journals. He has been the Executive Secretary of the International Conferences on Coordination Chemistry (1988-2012) and served as chair or on organizing committees of many other international conferences. He has been President of the inorganic Chemistry Division of the International Union of Pure and Applied Chemistry (IUPAC) and has been serving on several IUPAC Committees, most recently as co-chair of the management of the International Years of the Periodic Table, 2019. He has also been and is still active in a number of European COST actions in Chemistry. For the Royal Netherlands Chemical Society he acted as vice-president and president and has been an honorary member since 2003. He has also served the Netherlands Foundation of Chemical Research. During his career he spent sabbatical periods in Cambridge, Strasbourg, Louvain, Münster, Dunedin and Torun. He has been the Director of the Leiden Institute of Chemistry from 1993-2005. Kenneth Poeppelmeier Kenneth Poeppelmeier studied chemistry at the University of Missouri-Columbia from 1967 to 1971 (B.S. Chemistry). From 1971 to 1974, he was an Instructor in Chemistry at Samoa College in Western Samoa as a United States Peace Corps volunteer. He joined the research group of John Corbett at Iowa State University after leaving the Peace Corps and received his Ph.D. in 1978. He then joined the research staff of Exxon Research and Engineering Company, Corporate Research Science Laboratory, where he worked with John Longo and Allan Jacobson on the synthesis and characterization of mixed metal oxides and their application in heterogeneous catalysis. He joined the chemistry faculty of Northwestern University in 1984 where he is now the Charles E. and Emma H. Morrison Professor of Chemistry at Northwestern University and a NAISE Fellow joint with Northwestern University and the Chemical Sciences and Engineering Division-Argonne National Laboratory. He has published over 500 papers (1971-2023) and supervised over 200 undergraduates, PhD students, postdocs and visiting scholars. Leadership positions held include Director, Center for Catalysis and Surface Science Northwestern University, Associate Division Director for Science, Chemical Sciences and Engineering Division-Argonne National Laboratory, president of the Chicago Area Catalysis Club, Associate Director- NSF Science and Technology Center for Superconductivity, and Chairman of the ACS Solid State Subdivision of the Division of Inorganic Chemistry. His major research activities have been in Solid State and Inorganic Materials Chemistry focusing on heterogeneous catalysis, solid state chemistry and materials chemistry. His awards include National Science Council of Taiwan Lecturer (1991) , Dow Professor of Chemistry (1992–1994), AAAS Fellow, the American Association for the Advancement of Science (1993), JSPS Fellow Japan Society for the Promotion of Science (1997) , Natural Science Foundation of China Lecturer (1999), National Science Foundation Creativity Extension Award (2000 and 2022), Institut Universitaire de France Professor (2003), Chemistry Week in China Lecturer (2004), Lecturer in Solid State Chemistry, China (2005), Visitantes Distinguidos, Universid Complutenses Madrid (2008), Visiting Professor, Chinese Academy of Sciences (2011), twenty years of Service and Dedication Award to Inorganic Chemistry (2013) , Elected foreign member of Spanish National Academy: Real Academia de Ciencia, Exactas, Fisicas y Naturales (2017) , Elected Honorary Member of the Royal Society of Chemistry of Spain (RSEQ) (2018), and the TianShan Award Xinjiang Uygur Autonomous Region of China (2021). He has organized numerous symposia and conferences including the Chicago Great Lakes Regional ACS Symposium on Synthesis and Processing of Advanced Solid State Materials (1987), the New Orleans National ACS Symposium on Solid State Chemistry of Heterogeneous Oxide Catalysis, Including New Microporous Solids (1987), the Gordon Conference on Solid State Chemistry (1994) and the First European Gordon Conference on Solid State Chemistry (1995), the Spring Materials Research Society Symposium on Environmental Chemistry (1995), the Advisory Committee of Intense Pulsed Neutron Source (IPNS) Program (1996–1998), the Spring Materials Research Society Symposium on Perovskite Materials (2003), the 4th International Conference on Inorganic Materials-University of Antwerp (2004), and the Philadelphia National ACS Symposium on Homogeneous and Heterogeneous Oxidation Catalysis (2004). He has served on numerous Editorial Boards including Chemistry of Material, Journal of Alloys and Compounds, Solid State Sciences, Solid State Chemistry, and Science China Materials. In addition he as served on various Scientific Advisory Boards including for the World Premier International Research Center Initiative and Institute for Integrated Cell-Material Sciences Kyoto University, the European Center SOPRANO on Functional Electronic Metal Oxides, the Kyoto University Mixed-Anion Project, and the Dresden Max Planck Institute for Chemsitry and Physics.
