23. New Insights into Manganese Local Environment in MnS-1NanocrystalsAlenka Ristić, Matjaž Mazaj, Iztok Arčon, Nina Daneu, Nataša Zabukovec Logar, Roger Glaser, Nataša Novak Tušar, 2019, original scientific article Abstract: Manganese plays an important role in redox catalysis using zeolites as inorganic support materials, but the formation of the preferred redox manganese species (framework or extraframework) is still not well understood. Herein, the influence of the amount of manganese together with conventional and microwave-assisted hydrothermal synthesis paths on the formation of manganese species within the zeolite silicalite-1 (S-1) with MFI structure was investigated. It was found out that both synthesis procedures led to the formation of framework and extraframework manganese species, but in different molar ratios. However, the conventional synthesis procedure with all Mn/Si molar ratios generates more framework Mn in comparison to the microwave procedure. Additionally, the diminution of the zeolite crystals to nanoscale from 100 to 200 nm was achieved via the conventional procedure for the first time. UV–vis, Raman, and X-ray absorption spectroscopic analyses revealed different local environments of manganese: Mn3+ incorporated into the silicalite-1 framework as “framework manganese” and Mn2+/3+ present as “extraframework manganese” (Mn2O3, Mn3O4). TEM reveals the presence of Mn3O4 nanorods. Both framework manganese and extraframework manganese exhibit good catalytic activity for styrene epoxidation. Catalytic results suggest that, in oxidation reactions of hydrocarbons, framework manganese is more active at lower Mn contents (Mn/Si < 0.015), whereas extraframework manganese is more active at higher loadings (Mn/Si > 0.015).

29. PRIMERJAVA TREH MEDIJSKIH URESNIČITEV BALADE O TROBENTI IN OBLAKU CIRILA KOSMAČA (KNJIGA, FILM IN RADIJSKA IGRA)Nina Pušnar, 2016, undergraduate thesis Abstract: Diplomska naloga je osnovana na primerjavi treh medijskih uresničitev Balade o trobenti in oblaku: noveli Cirila Kosmača, filma režiserja Franceta Štiglica in radijske igre po radijski dramatizaciji Mitje Mejaka. V prvem delu najprej predstavim avtorje vseh treh uresničitev in izpostavim nekaj splošnih razlik med vsemi tremi različicami dela. Predstavim tudi glavne značilnosti obdobja, v katerem je nastala literarna predloga, in se dotaknem primerjave med bralcem, gledalcem in poslušalcem. V nadaljevanju primerjam vse tri medije in predstavim adaptacijo literarnega dela. Sledi tipologija pripovedovalca, nazadnje pa predstavim še vsebino vseh treh medijskih uresničitev. V drugem delu naloge primerjam vse tri medijske uresničitve, pri čemer se osredotočam na vsebino, pripovedovalca, simboliko, like, tematiko in motiviko, kompozicijo ter kraj in čas dogajanja. Na osnovi primerjave ugotovim, da med uresničitvami obstajajo pomembne razlike in zaključim, da je najboljša izmed vseh treh uresničitev Kosmačeva novela.
