Lives and work of the Serbian scientists

The Board for the study of lives and work of Serbian scientist and scientists of Serbian origin, established by the Serbian Academy of Sciences and Arts in 1992, has been publishing the edition entitled The Lives and Work of Serbian Scientists for 15 years now. The first volume was published in 1996. The 15 volumes that have been published so far portray the lives of over 150 scientific experts on nature, mathematics, medicine and technical sciences all of whom have leaf indelible mark on the world of science itself and the on Serbian culture in general both of which are greatly indebted to them and proud of their achievements. Following Volume 10, the Board published a special book in 2006 which contained English translation of the work summaries and biographies of 125 scientists mentioned in earlier editions. This special edition also contained a great deal of useful appendices in which scientists are classified according to the years of their birth, field of expertise, and the like. Basic information about the authors of the summaries has also been included. Readers now have before them Volume 13 of the Edition which contains biographies of 11 new scientists: 1 engineer (Jovan Surutka), 2 chemists (Dragutin Dražić and Milenko Ćelap), 3 physicists (Milenko Šušić, Stevan Koički and Milan Kurepa), 2 physicians (Bogdan Kosanović and Ivan Spužić), 2 biologists (Vladimir Pantić and Vojislav Petrović) and 1 geologist (Nikola Pantić). We are very pleased to once again express our appreciation to all Board members for their efforts on selecting competent authors and reviewers. We also welcome all of their comments and suggestions which helped this book maintain the same quality that the earlier editions are credited with. Acknowledgements are also extended to Mrs Vera Batina, Board Secretary, and the authors of particular articles, reviewers, benefactors, technical staff at the Serbian Academy and the people of the publishing company „Službeni glasnik".Биографије и библиографије / Српска академија наука и уметности : књ. 13.

Study of the reaction of hexanitrocobaltates(III) with amino acids. IV. The reations with DL-alanine, D-alanine, L-alanine, and β-alanine

The reactions of alkali hexanitrocobaltates(III) with DL-alanine, D-alanine, L-alanine, and β-alanine have been investigated. Thereby new classes of alkali dinitro-bis (aminoacido)cobaltates(III), M[CoAm2(NO2)2] were obtained. It was established that the products obtained contain two nitro groups in the cis position

Study of the reactions of hexanitrocobaltates(III) with amino acids. II. Determination of the configuration of dinitrobis(glycinato)cobaltate(III) ions

In a previously published paper1 we have undertaken a study of the reactions of hexanitrocobaltate(III) with amino acids. The first reaction we studied was that of glycine with potassium and sodium hexanitrocobaltate( III). In such a way the synthesis of a new class of complex compounds, dinitrobis (glycinato)- cobaltates(III) (MI[Co(H2NCH2COO)2(N02)2]), was given

Study of the reactions of hexanitrocobaltates(III) with amino acids. VII. Geometrical isomerism and absolute configuration of dinitrobis(aminoacidato)cobaltate(III) ions

Dinitrobis(aminoacidato)cobaltate(III) salts with L-α-aminobutyric acid, aminoisobutyric acid, L-valine, L-norvaline, L-leucine, L-norleucine, and L-isoleucine were prepared and resolved into optical isomers. We report their electronic absorption, circular dichroism and infra-red spectra, and some PMR spectra. The date confirm our earlier assumption of the geometrical isomerism and absolute configuration of analogous ions with glycine, alanine, and β-alanine. The only geometrical isomer found in our preparations is the cis dinitro complex with amino groups trans. The (+)589-optical isomers are assigned the P(C2) absolute configuration
