42. Can we explain strict ordering restrictions with extralinguistic properties?Franc Marušič, Petra Mišmaš, Rok Žaucer, Luka Komidar, Gregor Sočan, unpublished conference contribution Abstract: Cartographic approach to syntax models strict universal word orders with a universal hierarchy of functional projections. For example, universal order of adjectives [Adjs]
(cf. Hetzron 1978, Sproat & Shih 1991, etc.), supposedly comes from a universal hierarchy of
FPs which host specific types of Adjs (Scott 2002). Adopting this as a premise, we explore the
origin of this hierarchy, i.e., the origin of the specific ordering of individual FPs in the
functional hierarchy and thus the origin in which Adjs end up being linearized.
Keywords: adjectives, cartography, universal hierarchy of functional projections, general cognition, experimental syntax, cognitive foundations of syntax

44. Ceramic synthesis of disordered lithium rich oxyfluoride materialsJean-Marcel Ateba Mba, Iztok Arčon, Gregor Mali, Elena Tchernychova, Ralf Witte, Robert Kruk, Miran Gaberšček, Robert Dominko, 2020, original scientific article Abstract: Disordered lithium-rich transition metal oxyfluorides with a general formula Li1þxMO2Fx (M being a transition
metal) are gaining more attention due to their high specific capacity which can be delivered from the facecentered
cubic (fcc) structure. The most common synthesis procedure involves use of mechanosynthesis. In
this work, ceramic synthesis of lithium rich iron oxyfluoride and lithium rich titanium oxyfluoride are reported.
Two ceramic synthesis routes are developed each leading to the different level of doping with Li and F and
different levels of cationic disorder in the structure. Three different Li1þxMO2Fx samples (x ¼ 0.25, 0.3 and 1) are
compared with a sample prepared by mechanochemical synthesis and non-doped LiFeO2 with fcc structure. The
obtained lithium rich iron oxyfluoride are characterized by use of M€ossbauer spectroscopy, X-ray absorption
spectroscopy, NMR and TEM. Successful incorporation of Li and F have been confirmed and specific capacity that
can be obtained from the samples is in the correlation with the level of disorder introduced with doping,
nevertheless oxidation state of iron in all samples is very similar. Conclusions obtained from lithium rich iron
oxyfluoride are validated by lithium rich titanium oxyfluoride.

45. Study of water adsorption on EDTA dealuminated zeolite YO. L. Pliekhov, Olena Pliekhova, Iztok Arčon, Federica Bondino, Elena Magnano, Gregor Mali, Nataša Zabukovec Logar, 2020, original scientific article Abstract: Zeolite Y was synthesized and modified with EDTA dealumination procedure. The modified zeolites were
analyzed by X-ray diffraction, X-ray absorption spectroscopy, chemical analysis and water adsorption measurements.
We demonstrated that dealumination with bulk organic acid such as EDTA is able to reduce the
original intense water affinity. Furthermore, it was found that dealumination with EDTA, in contrast with
steaming and HCl dealumination, provides fully controllable, predictable and secure process of Al removal from
the zeolites’ frameworks. The shift of the adsorption isotherm in the low partial pressure range represents an
interesting result for adsorption-based applications.

46. Anaerobic Co-Digestion of Ligno-Cellulosic degradation products - Wood Resin Residue from Tannin ProductionGregor Draago Zupančič, Mario Panjicko, Domagoj Eršek, Goran Lukić, Žiga Velišček, Martin Gojun, 2018, published scientific conference contribution Abstract: Tannin is a very versatile industrial material used for many applications. During tannin production, a residue is produced, which consists of 10 – 15 % sodium acetate solution with up to 10 % water-soluble wood resins by mass. Since it contains a high portion of acetate, it can be useful for anaerobic digestion to produce biomethane, whereas wood resins may exhibit inhibitory effects. In order to test the biodegradability of wood resin residue, several batch tests were performed with two approaches. In the first approach, co-digestion with corn-silage and animal waste was performed utilizing suspended biomass inoculum. In the second approach, co-digestion with pulp and paper wastewater was performed utilizing granular biomass inoculum. In the first approach, the results showed partial inhibition of degradation using mixtures of 25.6 % and total inhibition using 100.0 % of wood resin. Maximum biodegradability achieved was 83.4 %. In the second approach, the results showed partial inhibition of degradation using mixtures of 1.7 and 3.3 % of wood resin. Maximum biodegradability achieved was 64.3 %. Because the second approach enabled us to process larger quantities of wood resin (larger COD load), a pilot experiment of anaerobic co-digestion with pulp and paper wastewater was performed, utilising similar conditions to the considered full-scale treatment. The results showed COD degradation between 70.1 and 81.7 % and a potential increase in total produced biomethane of 36 – 39 %, with no significant adverse effects. Wood resin residue yielded 45 – 50 m3 of biomethane per tonne, which exhibits a good potential for biomethane production. If used for biomethane production in pulp and paper wastewater treatment, the valorisation value of the wood resin residue is between 54,500 € and 94,000 €, which makes the presented treatment also an economically viable option.

47. Kružna ekonomija u prehrambenoj industriji i industriji pića, visokovrijedni proizvodi te energetsko i materijalno iskorištavanje otpada i nusproizvodaGregor Drago Zupančič, Mario Panjicko, Anamarija Havliček, Goran Lukić, 2019, published scientific conference contribution abstract Abstract: Prehrambena industrija i industrija pića su s godišnjim prihodima od 1190 milijardi € među najvažnijim granama gospodarstva u EU, koje također proizvode i značajne količine nusproizvoda i otpada. Posljednjih godina, kroz uvođenje strategija kružne ekonomije, posebna pažnja posvećuje se iskorištavanju otpadnih tokova iz kojih je moguća proizvodnja visokovrijednih proizvoda. U ovom radu prikazani su primjeri iz proizvodnje hrane i pića, u kojima je iz nusproizvoda moguće proizvoditi aktivne spojeve kao npr. Resveratrol koji ima antikancerogeni učinak, različite polu proizvode kao što su fenolni spojevi, dodaci u prehrani i sl. U radu je posebna pažnja posvećena pivarskoj industriji gdje se iz nusproizvoda (pivske komine) proizvode prehrambeni proteini te i mljekarskoj industriji gdje se iz sirutke proizvode mliječne kulture, vitamini, laktoza, laktat i proteini (npr. aktoferini, laktoperoksidaze, imunoglobulini). U smislu strategije kružne ekonomije, ostatci nakon dobivanja novih proizvoda, koji više ne sadrže vrijedne tvari, moraju se zbrinuti na odgovarajući način. Najpovoljnija i najčešće upotrebljena tehnologija zbrinjavanja je anaerobna digestija. Anaerobnom digestijom moguće je otpadne tokove zbrinuti na način da se količine otpada smanje i do 90% te da se proizvedeni bioplin upotrijebi kao obnovljiv izvor energije u samom proizvodnom procesu. Time je moguće ostvariti smanjuje emisija ugljičnog dioksida do 50%.
