MPDS Editor Team

Pierre Villars, as editor-in-chief, is collaborating with the following section editors:


Dr. Karin Cenzual

graduated in chemistry. After having had two children, she returned to science and obtained a Ph.D. in Crystallography at Geneva University (1988) for the thesis "Crystal Chemical Concepts Applied to a Series of New Intermetallic Structures". From 1988 to 1995 she collaborated on Gmelin Handbook: "TYPIX, Standardized Data and Crystal Chemical Characterization of Inorganic Structure Types" (1993/1994) and prepared the database "TYPIX95" (Gmelin Institute). Since 1996, she is employed by the Department of Inorganic, Analytical and Applied Chemistry, Geneva University, to work on the Pauling File project. Co-author of some 30 publications, among which two papers on corrections of crystal structures described in wrong space groups and a review paper in "Handbook of Superconductivity" (Academic Press, 2000).

Jo L. C. Daams

Started in the Structure Analysis Department of the Philips Research Laboratories Eindhoven in 1964, where he was concerned with transmission and scanning electron microscopy. He studied chemistry at various levels and since 1976, after changing to the X-ray diffraction group, has worked on a wide range of applied chemistry subjects. In 1983 he joined the Metals Department as a research scientist especially for crystal- and microstructure analysis from X-ray diffraction experiments. In 1986 he began a cooperative effort with Dr. Villars, aiming at finding systematic relations between crystal structures (atomic environments) and physical properties of intermetallic compounds. This cooperation resulted a.o. in 1991 in the publication of the "Atlas of Crystal Structure Types for Intermetallic Phases" (published by ASM International). Since his retirement from Philips Research Laboratories Eindhoven, in 1999, he is working as an independent consultant on crystal structure data and as such involved in the PAULING FILE materials design system.

Dr. Fritz Hulliger

physicist; thesis on "Magnetism and electrical Conductivity in Transition-Element Compounds" under Professor G. Busch (1959), worked on transition-element and rare-earth compounds with Cyanamid European Research Institute, Geneva, 1961-1968, and Solid-State Physics Laboratory, ETH, Zurich, until 1997: author or co-author of about 200 publications, among them a book on "Structural Chemistry of Layer-Type Phases" (Reidel 1976) and two review papers (in Structure and Bonding, vol. 4., 1986, and in Handbook on Physics and Chemistry of Rare Earth, vol. 4, 1979) as well as three contributions to Landolt and Börnstein.

Prof. Hiroaki Okamoto

Is professor at Asahi University, Hozumi-cho, Gifu, Japan. Co-editor of ASM's primary binary phase diagrams reference work, the 3-volume set Binary Alloys Phase Diagrams, Second Edition , and the electronic edition of this work, Binary Alloy Phase Diagrams, Second Edition, Plus Updates, on CD-ROM. Dr. Okamoto has also published classic articles on common mistakes made in drawing phase diagrams. He is Supplemental Literature Review Editor for Journal of Phase Equilibria since 1991. He was senior technical editor, Alloy Phase Diagram Program, ASM International, from 1987 through 1993. He obtained his master's degree in applied physics from Nagoya University in 1965, and his doctorate in metallurgy from the University of Illinois in 1971. Earlier in his career, he worked on the evaluation of binary gold systems at Carnegie-Mellon University in Pittsburgh and on the evaluation of beryllium alloy systems at the Lawrence Berkeley Laboratory in California. He was editor of Phase Diagrams of Binary Iron Alloys and Desk Handbook: Phase Diagrams for Binary Alloys (ASM International, 1993 and 2000), and co-editor of Phase Diagrams of Binary Gold Alloys, Phase Diagrams of Binary Beryllium Alloys, and Phase Diagrams of Binary Indium Alloys and Their Engineering Applications (ASM International, 1987, 1987, and 1991, respectively). He was also a co-editor of the 10-volume Handbook of Ternary Alloy Phase Diagrams (ASM International, 1995).

Dr. Kenji Osaki

Professor Emeritus, Structural Chemistry Department, Faculty of Pharmaceutical Sciences, Kyoto University. Dsc, Osaka University, 1958. Started crystal structure work in 1943 at the laboratory of structural chemistry, headed by Professor I. Nitta. Served as referee in this field for more than 20 years. Engaged in creation, checking, retrieval and application of crystal structure data since 1975. Permanent member of the Committee for Crystallographic Information, Crystallographic Society of Japan.


Dr. Alan Prince

was associate professor in the Department of Materials Technology, Brunel University, England. He read metallurgy at Sheffield University and graduated in 1948. He joined Imperial Chemical Industries to work at plants in Widnes and Billingham, then became lecturer in metallurgy at the University of Southampton in 1953. Three years later, he joined The General Electric Company, Simon Carves Atomic Energy Group. In 1961, as chief metallurgist with GEC, Histon Research Centre, Wembley, he and colleague Dr. Dain Evans formed a research group to study ternary phase diagrams. He retired from GEC in 1987. In 1991, he received a doctorate of metallurgy from the University of Sheffield. As editor-in-chief of the Higher-Order Alloy Phase Diagram Programme of the Alloy Phase Diagram International Commission, he was intimately concerned with the international collaborative effort to critically assess ternary phase diagram data.

Alan Prince died in autumn 1999.
