My dissertation about chemical investigations of ruthenium, osmium and hassium and the CALLISTO project has been published in November/December 2003 by the ibidem-Verlag (ISBN 3-89821-315-3, 156 pages, format 30 cm x 21 cm, many coloured illustrations, in German language). It should be available in the local bookstores upon special request. Thus, an additional electronic publication on this website is not foreseen at the moment.
