On the activity of the LIMOS R&D Group in the field of ‘materials world’
G.Kaptay University of Miskolc, Department of Physical
Chemistry, LIMOS R&D As a guest editor of this issue of the e-journal “Materials World” let me introduce the readers to the R&D group called LIMOS, established by me about a decade ago. LIMOS is an acronym for “Liquid Metals and Molten Salts”, indicating the two main types of phases our work has been concentrated on. At least, four other types of phases should be mentioned, involved in our studies: ceramics (including oxides, borides, nitrides, carbides and carbon in different forms), solid metals, molten slags and of-course the gas/vapour phase. These six phase-types altogether in different combinations cover all materials systems studied by us so far, and this situation is not likely to change… Regarding the methods applied, ‘physical chemistry’ is the key word for our studies, in its very different aspects, including micro- and macromodelling, measurements of physical properties and synthesis of materials in laboratory scale. In the very wide aspects of physical chemistry the main emphasis is on thermodynamics, interfacial physical chemistry and electrochemistry. LIMOS is nor a cooperation, neither an official part of a university. LIMOS is rather a group of people connected by the desire to make research. Some members do fundamental research just for “fun”, to find out more about mother-nature, but some (usually more experienced) members do applied R&D. As a rule, students join us during their 2nd or 3rd under-graduate year, while studying Physical Chemistry as part of their curriculum of Metallurgical Engineering or Materials Engineering. They always start with “small” problems, usually connected with some measurements, but it becomes soon or later obvious for everyone that in any “small” problem always the whole complexity of the matter is involved. In this way particular subjects become inter-connected within the group both horizontally and vertically. Students usually move from more basic questions towards some more applied problems. The best of them do this journey repeatedly in inter-connected areas, increasing their capabilities. The driving force for a student to join our group is to find a solid basis to prepare his or her first “student research work”, participate on student conferences, and further to prepare a Diploma Work for MSc, maybe to be enrolled on the PhD course, and to get the PhD degree. Some of the students make only the first steps with us, and on higher years join some other groups of the Faculty. Some make the opposite – start with some other professors and join us at later stages. Some members joined us already being engineers or even PhD-s. We are opened to everyone and are also opened to cooperation with other groups both inside and outside our Faculty, both in this country and also at the international level. The official language of LIMOS is English. We speak different versions of English, mainly Hungarian-style, but some Persian and Russian accent is present, as well. All total 27 past and present members of LIMOS are shortly presented in Appendix 1. In early years LIMOS was financed mainly from personal founds. Today we have a good balance of academic, government and industrial founding, covering the costs of our personal needs, research equipment and materials and the costs of communication with the international scientific community, including extensive participation on conferences. The main results of our activity can be measured in the number and level of publications. In Appendix 2 our main research topics are summarised with key words. All research topics dealt by us so far can be divided into the following four large areas: Chemical Thermodynamics, Interfacial Science, Electrochemistry and Industrial Applied Research. Journal papers, and selected proceedings papers are collected in Appendix 3, together with major manuscripts of different levels (student research works, student diploma works, MSc Diploma Works, PhD Thesis, and a dr.habil thesis). Although the field of metallurgy is not very rich in impact factors (for instance BKL Kohászat, the Hungarian metallurgical journal is even not listed by ISI), nevertheless, the cumulative impact factor of LIMOS at the moment is about 22. The more important characteristics of our impact is that about 80 LIMOS-independent references have been obtained for our publications (see Appendix 3). The dynamics of our publications and that of LIMOS-independent references is presented in Fig.1. (for end of 2000). It is worth to mention that in addition to written works opened to public we have written 160 manuscripts (including industrial reports, reviews, etc), have delivered 150 oral and poster presentations on conferences and 100 presentations on scientific workshops and seminars. Fig.1. Cumulative publications of LIMOS and references obtained (for end of 2000) top: publications (journal + proceedings + manuscripts – see Appendix 3) bottom: references obtained on the above (see Appendix 3) In the present issue of this e-journal we are going to present some of our very recent results. In this way we intend to give a cross-section of subjects and ideas we are currently working on. We would appreciate any comments from the visitors of this web-site to our central e-mail address: fkmkap@ gold.uni-miskolc.hu. Let us say to you good by with our traditional Jó szerencsét, Glück auf, Good luck, Yours, LIMOS LIMOS LIMOS LIMOS LIMOS LIMOS LIMOS LIMOS LIMOS LIMOS LIMOS Acknowledgements The author is grateful for his first professors at the Leningrad Polytechnic, Russia, prof. M.M.Vetyukov, Ju.V.Borisoglebskii and A.G.Morachevskii, who helped to make my first steps in science. Great thanks are due to prof. E.Berecz, who honoured me by a position in 1997, after my return from Russia, at the department of Physical Chemistry. All colleagues and students of the Faculty of Materials and Metallurgical Engineering of the University of Miskolc are also acknowledged for their inspiration – the majority of subjects of our study raised from the cooperation with them. Thanks are due of-course to now more than 100 of our co-authors from different institutions and countries.
Appendix 1. Past, Present, and Honoris Causa Members of the LIMOS R&D Group
Before starting the list of LIMOS members, we first should mention prof. Dr. h.c. Dr. Endre BERECZ as our ”LIMOS Member Honoris Causa”. Without his support LIMOS would have never been founded. He graduated as chemist (1949) at Pázmány Péter University (Budapest). Got his dr.rer.nat. in 1960 from the same University (renamed by that time as Eötvös Lóránt University). Got his CSc from the University of Leningrad in 1954, and his DSc in 1974 from the Hungarian Academy of Sciences. In the period between 1963 and 1990 he was a Head of Department of Physical Chemistry of the University of Miskolc. Today he is a Professor Emeritus of this University. He worked in the fields of thermodynamics and electrochemistry of electrolytes, solutions and molten salts and established the subject of environmental chemistry at this University. The ordinary LIMOS-members are as follows:
At this point this list seems to terminate. In fact, this point is just the beginning of the next line. Our minds and hearts are open to involve anyone who REALLY wants to JOIN us and who REALLY wants to WORK with us.
