114. Empirical observations on the interpretation of the Macedonian articles : master's thesisMetodi Efremov, 2024, magistrsko delo Opis: 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.

118. Kako se približati umetninam, umetnicam in umetnikom, umetnosti?Aleš Vaupotič, 2023, samostojni strokovni sestavek ali poglavje v monografski publikaciji Opis: 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.
Ključne besede: Moderna galerija, dostopnost razstav, restavratorstvo, konservatorstvo

120. XAS analysis of bifunctional Ni/ZSM-5 catalystsIztok Arčon, Hue-Tong Vu, Goran Dražić, Janez Volavšek, Gregor Mali, Nataša Zabukovec Logar, Nataša Novak Tušar, 2024, objavljeni povzetek znanstvenega prispevka na konferenci Opis: 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.
