Self-cleaning and photoactive TiO2 – ZrO2 – SiO2 films on thermosensitive and glass substrates
Urška Lavrenčič Štangar, Nives Vodišek, 2017, objavljeni povzetek znanstvenega prispevka na konferenci

Opis: Nanosized TiO2 is well-known for its photocatalytic property. From the combination of photocatalysis and photoinduced hydrophilicity properties, thin films of this material have also anti-fogging, self-cleaning and antimicrobial properties. There are numerous deposition techniques e.g. spin-coating, dip-coating, spraying, the most suitable one is chosen based on substrate or solution characteristics. Thin films are often required to be transparent for visible light, especially if we use them on transparent substrates, or they should not affect the color of the substrate. Radicals that are produced during photosensitizing process are able to destroy structure of a substrate and substrate can lose mechanical stability [1,2]. Some studies show that adding a SiO2 protective layer can prevent the damage of the substrate [3–5]. Ti-Zr containing sols were prepared with sol-gel process, where titanium(IV) isopropoxide, zirconium(IV) butoxide and ethanol were hydrolyzed with aqueous solution of perchloric acid. Solution was then refluxed for 48 hours. During that time crystallization and deaggregation took place and that resulted in a stable final solution [6]. To prepare suitable solution for production of durable films silica binder was added. On glass and plastic substrates, thin films were deposited with the dip-coating method and dried with a heat-gun. Thin films were characterized by measurements of photocatalytic activity with terephthalic acid as model organic pollutant subjected to oxidation via fluorescent degradation product, photoinduced superhydrophilicity phenomena, UV-Vis and ATR-FTIR spectroscopy, SEM images, as well as mechanical properties measurements.

Adjectives, hierarchies and cognition
Petra Mišmaš, predavanje na tuji univerzi

Opis: In this talk we will focus on the universal hierarchy of functional projections that host specific types of adjectives and the source of this hierarchy. To achieve this, the talk will consist from two parts. In the first part, the relevant background on the cartographic approach and the order of attributive adjectives will be given. In the second part of the talk, the focus will be on experiments which were conducted to establish if cognition can be taken as a source of the universal hierarchy of functional projections. Specifically, we will first consider the cartographic approach to syntax. Cartography suggests that phrases consist from lexical heads which are dominated by hierarchies of functional projections. Crucially, these hierarchies are argued to be universal, see a. o. Cinque & Rizzi (2008) for an overview of the cartographic program. This also holds for the noun phrase in which functional projections host, among other material, adjectives. This view then gives a natural explanation for the order of attributive adjectives which was said to be universal as well, see for example Hetzron (1978), Cinque (1994), Scott (2002). That is, the order of adjectives is universal because adjectives are hosted by functional projections which appear in a universal hierarchy. The second part of the talk will focus on the source of the universal word order and the functional hierarchy that dictates it. Following Cinque & Rizzi (2008) and Ramchand & Svenonius (2014), we will consider general cognition as one possible source of the universal hierarchy of functional projections. Specifically, I will report on a series of experiments which are a result of joint work with Rok Žaucer and Franc Marušič and are a part of an ongoing project "Probing the cognitive basis of the cartographic hierarchy of functional projections in the noun phrase" financed by the Slovenian Research Agency and conducted at the University of Nova Gorica. Crucially, these experiments are conducted to test the hypothesis that if the universal hierarchy is dictated by general-cognition restrictions, then the order of projections hosting adjectives should be reflected in various non-linguistic cognitive processes. To test this prediction, we are focusing on adjectives for size, color, and shape which seem to universally come in the order size > shape > color. In the talk, I will report on the results of the experiments as well as our future plans.

La poésie slovène et italienne sur Trieste et la Première Guerre mondiale
ana toroš, samostojni znanstveni sestavek ali poglavje v monografski publikaciji

Opis: Cet article traite de la poésie slovène et italienne de la première moitié du XXème siècle dont l’espace narratif est la ville de Trieste et son arrière–pays. Pendant la Première Guerre mondiale, les poètes slovènes décrivent les événements du Front de la Socˇa, se passant près de la région triestine où sévit une longue bataille entre l’Autriche–Hongrie et l’Italie, dans laquelle beaucoup de soldats slovènes ont péri. Par contre, les poètes italiens parlent de la Première Guerre mondiale dans la région triestine pour la plupart de manière irrédentiste, donc, ils expriment le désir de rattacher Trieste à l’Italie.

Ultra-high energy neutrinos searches with the Pierre Auger Observatory
Lukas Zehrer, Gašper Kukec-Mezek, Samo Stanič, Serguei Vorobiov, Danilo Zavrtanik, Danilo Zavrtanik, Marta Trini, 2019, objavljeni znanstveni prispevek na konferenci

Opis: In the EeV range, neutrinos are expected to be produced by ultra-high energy cosmic rays interactions with the Cosmic Microwave Background during propagation in the Universe. We report on the search for ultra-high energy neutrinos in data collected with the Surface Detector of the Pierre Auger Observatory. The searches are most efficient in the zenith angle range from 60 degrees to 95 degrees with tau neutrinos skimming in the Earth playing dominant role. The present non-detection of UHE neutrinos in the Pierre Auger Observatory excludes the most optimistic scenarios of neutrino production in terms of UHE cosmic rays chemical composition and cosmological evolution of the acceleration sites. We also report on the searches for neutrinos in coincidence with the recent Gravitational Wave events detected by LIGO/Virgo.

Determination of Dissolved Iron Redox Species in Freshwater Sediment using DGT Technique Coupled to BDS
Yue Gao, Arne Bratkič, Dorota Korte, Aleksander Kravos, Hanna Budasheva, Mladen Franko, 2019, izvirni znanstveni članek

Opis: In this work we have developed a novel method for determination of iron redox species by the use of diffusive gradients in thin-film (DGT) technique coupled to photothermal beam deflection spectroscopy (BDS). The combination of both methods achieved low limit of detection (LOD) of 0.14 μM for Fe (II) ions. The total Fe concentration determined in the Vrtojbica river sediment (Slovenia, Rožna Dolina, 5000 Nova Gorica) was 49.3 μgL–1. The Fe (II) and Fe (III) concentra- tion amounted to 12.8 μgL–1 and 39.9 μgL–1, respectively. Such an approach opens new opportunities for monitoring the content of iron species in natural waters and sediments and provides highly sensitive chemical analysis and an accurate qualitative and quantitative characteristic of the materials under study.
