53. Unraveling the arrangement of Al and Fe within the framework explains the magnetism of mixed-metal MIL-100(Al,Fe)Gregor Mali, Matjaž Mazaj, Iztok Arčon, Darko Hanžel, Denis Arčon, Zvonko Jagličić, 2019, original scientific article Abstract: Properties of mixed-metal MOFs depend on the distribution of different
metals within their frameworks. Determination of this distribution is often very
challenging. Using an example of aluminum- and iron-containing MIL-100, we
demonstrate that 27Al NMR spectroscopy, when combined with first-principles
calculations and magnetic, X-band electron paramagnetic resonance, Fe K-edge extended
X-ray absorption fine structure, and Mössbauer measurements, enables one to accurately
determine the arrangement of Al and Fe within the metal trimers, which are the basic
building units of MIL-100. In this particular material, the incorporation of Fe and Al on
the framework metal sites is random. Crucial for deciphering the arrangement is detecting
NMR signals, shifted because of the strong hyperfine interaction between the 27Al nuclei
and the unpaired electronic spins of Fe3+ ions, assigning the shifted signals aided by first-principles calculations of hyperfine
couplings, and quantitatively evaluating the NMR intensities and the measured effective magnetic moment.

54. Oprema za izboljšanje snemanjaGregor Dvornik, 2019, undergraduate thesis Abstract: Diplomsko delo predstavlja tehnologijo in pripomočke, ki se uporabljajo pri snemanju.
V nalogi so tako predstavljeni nekateri najbolj uporabljeni pripomočki pri snemanju, kot so žerjav, voziček, helikopter, gimbal in drugi. Vsak pripomoček ima tudi predstavljeno kratko zgodovino nastanka ter opisano njegovo uporabo.
Zgodovina teh pripomočkov je zelo slabo ohranjena. V večini primerov se oprema kar pojavi pri snemanju. Temu lahko pripišemo hiter razvoj filmske industrije in potrebi po izboljšanju vizualnega doživetja gledalcev.
V diplomski nalogi je predstavljena uporaba in delovanje pripomočkov ter domača ali DIY izdelava in nasveti, zakaj da in zakaj ne pripomoček narediti doma.
Keywords: Oprema, pripomočki snemanja, zgodovina propomočkov, tehnologija, delovanje

59. High-temperature stabilization of bulk amorphous Al2O3Andraž Mavrič, Mattia Fanetti, Gregor Mali, Matjaž Valant, 2018, original scientific article Abstract: We present a method for high temperature stabilization of bulk amorphous aluminium oxide. The stabilization is achieved by dispersing polysilane dendritic molecules in aluminium hydroxide gel, which upon thermal treatment gives amorphous aluminium oxide stable up to 900 °C. The dispersed macromolecules covalently bind to the alumina matrix and induce homogeneously distributed strain fields that keep the alumina amorphous. The thermal conversion of the precursor system was followed by thermogravimetry with an evolved gas analysis, infrared spectroscopy and 29Si NMR. The amorphous structure of aluminium oxide was confirmed with an X-ray and electron diffraction. Additionally, the amorphous state was supported by presence of penta-coordinated aluminium detected by 27Al NMR and a low bandgap measured by a UV–visible absorption spectroscopy.

60. Primjena pivskog tropa u proizvodnji bioplinaMario Panjicko, Gregor Drago Zupančič, Marina Tišma, Bruno Zelić, 2017, independent scientific component part or a chapter in a monograph Abstract: Pivarska industrija je veliki generator otpadnih tokova. Pivski trop, kao jedan od tri glavna otpada toka, po kemijskom je sastavu lignocelulozni materijal. Zbog sve većeg porasta cijena energije i povećane brige za očuvanjem okoliša, u zadnje vrijeme se provode brojna istraživanja procesa anaerobne razgradnje (anaerobne digestije) pivskog tropa u svrhu proizvodnje bioplina.
Bioplin proizveden prilikom procesa anaerobne razgradnje sastoji se najvećim dijelom od metana (CH4) i ugljikovog dioksida (CO2), s malim udjelima sumporovodika (H2S) i amonijaka (NH3) te plinova koji se mogu naći u tragovima, kao što su vodik (H2), dušik (N2), ugljikov monoksid (CO), zasićeni ili halogenirani ugljikovodici te kisik (O2).
Osnovni problem primjene pivskog tropa u procesu anaerobne razgradnje u svrhu proizvodnje bioplina je njegov složen kemijski sastav. Strukturna kompleksnost lignina, njegova kemijska stabilnost i netopljivost posebice otežavaju proces anaerobne razgradnje.
U ovom pregledu prikazane su osnove procesa anaerobne razgradnje, vrste reaktora za provedbu procesa anaerobne razgradnje te su opisane mogućnosti primjene pivskog tropa u procesu anaerobne razgradnje.
Keywords: anaerobna razgradnja, bioreaktori, lignoceluloza, bioplin, pivski trop
