Abstract: This thesis investigates the use and the interpretation of three alleged definite articles in Macedonian from a formal perspective. It is concerned with the following questions: (i) does Macedonian indeed have a definite article? (ii) are all three articles in Macedonian definite articles or demonstratives? (iii) what are the formal features that distinguish among these items and how are they licensed in different semantic contexts? The thesis provides evidence that Macedonian has only one definite article – the t-root one – as it presupposes uniqueness and does not have a deictic feature. The other two items – the v- and n-root articles – are at the intersection of a definite article and a demonstrative: they have a deictic feature but do not presuppose uniqueness or non-uniqueness. In addition, it is demonstrated that Macedonian has a set of three demonstratives that have a deictic feature and presuppose non-uniqueness.

Abstract: Razstava z naslovom Od blizu - Moderna galerija, Ljubljana, 22. 12. 2022-2. 4. 2023 - je drugačna od običajnih razstav v Moderni galeriji, od razstav v galerijah nasploh, saj na njej niso predstavljena samo umetniška dela, ampak predvsem postopki ohranjanja teh del v muzejih. Slike, kipi, tudi videi in prostorske postavitve, vse to se sčasoma spreminja ali celo poškoduje. Pose- bej usposobljene strokovnjakinje in strokovnjaki z zelo širokega področja umetniških, humanističnih in naravoslovnih disciplin si zato s svojim raziskovalnim in zahtevnim strokovnim delom pri- zadevajo ta dela čim dlje ohraniti v stanju, da jih lahko gledamo in doživljamo na razstavah.

Abstract: In a bifunctional Ni/ZSM-5 zeolite type catalyst, catalytic properties are usually tuned via varying Al and Ni contents [1]. Here we present a systematic structural study of the Ni/ZSM-5 materials by Ni K-edge XANES and EXAFS analyses, to monitor the changes of local structure and chemical state of Ni species in the catalysts as a function of Al and Ni content. A series of Ni/ZSM-5 type zeolites with different Al to Si and Ni to Si molar ratios were synthesized by a “green”, template free technique [2]. With a combination of XAS, XRD and TEM we resolved the changes in the local environment of Ni species induced by the different Al contents in the Ni/ZSM-5 catalysts. Ni species in Ni/ZSM-5 exist as NiO nanocrystals and as charge compensating Ni2+ cations. The Ni K-edge XANES and EXAFS results enabled the quantification of Ni-containing species. At a low Al to Si ratio (nAl/nSi < 0.04), the NiO nanoparticles predominate in the samples and account for over 65% of Ni phases. However, NiO is outnumbered by Ni2+ cations attached to the zeolite framework in ZSM-5 with a high Al to Si ratio (nAl/nSi = 0.05) due to a higher number of framework negative charges imparted by Al. The obtained results show that the number of highly reducible and active NiO nanocrystals is strongly correlated with the framework Al sites present in Ni/ZSM-5 zeolites.
