On the Distribution of Imperfective Suffixation and the Position of Theme Vowels in Slovenian
Vesna Plesničar, objavljeni povzetek znanstvenega prispevka na konferenci

Opis: There are different views regarding the exact position of the Theme Vowel (TH) in the verb structure within Distributive Morphology (DM). One is that THs are realisations of a TH position that is added to v0 (and other functional heads) (e.g. Oltra-Massuet 1999 and Embick and Halle 2005), another, argued for in Marvin (2002), is that THs are attached directly to the ROOT. The most recent proposal for Slovenian is the one made by Božič (2016, 2017), where he argues that TH is adjoined to Aspectual head (ASP0). On the other hand, Marvin has claimed, contra Božič (2017), that TH could only adjoin to category-defining heads, i.e. that adjunction to any other functional head, such as Tense head, Aspect or Passive is not possible in Slovenian. Our data suggest that contrary to Božič, it is -va- rather than -av- that is an imperfectivizing morpheme in Slovenian, and contrary to previous literature more widely, -va- is not just a secondary imperfective morpheme but more generally an imperfective morpheme. Our idea is supported by the clear distribution patterns shown by -va- in verbs which receive an imperfective interpretation. This suggestion makes further predictions on the position of TH vowel in Slovenian. We argue that TH precedes the imperfective suffix -va-, and thus cannot be a component of the imperfective morpheme, as assumed in Božič (2016, 2017). TH is rather a part of the ROOT (or verbalizing head to which it is attached).

Effect of the Morphology of the High-Surface-Area Support on the Performance of the Oxygen-Evolution Reaction for Iridium Nanoparticles

Opis: The development of affordable, low-iridium-loading, scalable, active, and stable catalysts for the oxygen-evolution reaction (OER) is a requirement for the commercialization of proton-exchange membrane water electrolyzers (PEMWEs). However, the synthesis of high-performance OER catalysts with minimal use of the rare and expensive element Ir is very challenging and requires the identification of electrically conductive and stable high-surface-area support materials. We developed a synthesis procedure for the production of large quantities of a nanocomposite powder containing titanium oxynitride (TiONx) and Ir. The catalysts were synthesized with an anodic oxidation process followed by detachment, milling, thermal treatment, and the deposition of Ir nanoparticles. The anodization time was varied to grow three different types of nanotubular structures exhibiting different lengths and wall thicknesses and thus a variety of properties. A comparison of milled samples with different degrees of nanotubular clustering and morphology retention, but with identical chemical compositions and Ir nanoparticle size distributions and dispersions, revealed that the nanotubular support morphology is the determining factor governing the catalyst’s OER activity and stability. Our study is supported by various state-of-the-art materials’ characterization techniques, like X-ray photoelectron spectroscopy, scanning and transmission electron microscopies, Xray powder diffraction and absorption spectroscopy, and electrochemical cyclic voltammetry. Anodic oxidation proved to be a very suitable way to produce high-surface-area powder-type catalysts as the produced material greatly outperformed the IrO2 benchmarks as well as the Ir-supported samples on morphologically different TiONx from previous studies. The highest activity was achieved for the sample prepared with 3 h of anodization, which had the most appropriate morphology for the effective removal of oxygen bubbles.

√ov Is in the Air: The Extreme Multifunctionality of the Slovenian Affix ov
Marko Simonović, Petra Mišmaš, 2020, izvirni znanstveni članek

Opis: In this paper we consider several instances of the Slovenian affix ov, which surfaces in many, apparently unrelated contexts. Here we focus on (i) ov in verbs, where it can act as an imperfectivizer or a verbalizer, (ii) ov found in possessive adjectives and kind adjectives derived from nouns, (iii) ov which precedes the adjectiviser (e)n in denominal adjectives, and (iv) ov in nominal declension (acting as a genitive case ending in dual and plural or as a dual/plural augment). Building on the observation that certain affixes function either as inflectional or as derivational (see Simonović and Arsenijević 2020), and working within a Distributed Morphology approach which postulates that derivational affixes should be analyzed as roots (e.g. Lowenstamm 2014), we argue for a single multifunctional ov. This ov is a potentially meaningless root that can take as a complement other roots (thus forming a “radical core”) or phrases, resulting in different structures and consequently different stress patterns and meanings, but can also act as an Elsewhere allomorph, whose insertion is guided by an interplay of phonological and morphological constraints.

Structural, morphological and chemical properties of metal/topological insulator interfaces
Katja Ferfolja, 2021, doktorska disertacija

Opis: Topological insulators (TIs) represent a new state of matter that possess a different band structure than regular insulators or conductors. They are characterized with a band gap in the bulk and conductive topological states on the surface, which are spin polarized and robust toward contamination or deformation of the surface. Since the intriguing properties of the TIs are localized at the surface, it is important to obtain knowledge of the possible phenomena happening at the interface between TIs and other materials. This is especially true in the case of metals, due to the fact that such interfaces will be present in the majority of foreseen TI applications. The presented study combines microscopy and spectroscopy techniques for characterization of morphology, stability and chemical interaction at the interface between TI and metals deposited by means of physical vapor deposition. Our research is based on the interface of Bi2Se3 topological insulator with Ag, Ti and Pt – metals that can be encountered in devices or applications predicted to utilize the special properties of topological insulators. STM and SEM imaging of Ag/Bi2Se3 interface showed that Ag atoms arrange on the surface in the form of islands, whereas significantly bigger agglomerates are found at the surface steps. The interface was found to be unstable in time and resulted in the absorption of the metal into the crystal at room temperature. Evidences of a chemical reaction at the Ag/Bi2Se3 interface are presented, showing that new phases (Ag2Se, AgBiSe2 and metallic Bi) are formed. Deposition of Ti on Bi2Se3 resulted in different morphologies depending on the film thickness. At a very low coverage (<1 Å) islands are formed. However, the islands growth is hindered before the completion of a full layer due to the occurrence of a chemical reaction. No surface features could be detected by SEM for Ti coverage up to 20 nm. In contrary, when Ti thickness reached 40 nm, compressive stress triggered buckling of the deposited film. XPS analysis revealed that a redox solid-state reaction occurs at the Ti/Bi2Se3 interface at room temperature forming titanium selenides and metallic Bi. The reaction has significant kinetics even at cryogenic temperature of 130 K. Pt forms a homogenous film over the whole substrate surface, which is stable in time at room temperature. Although the interface of Pt with Bi2Se3 was found to be i less reactive compared to Ag and Ti, an interfacial phase formed upon annealing to ∼90 °C was detected by TEM cross section experiment. A model for prediction of interfacial reactions between a metal and Bi2Se3 based on the standard reduction potential of the metals and Gibbs free energy for a model reaction is presented. Based on these two values the reaction can be expected to result in the formation of binary and/or ternary selenides and Bi. Presented work shows on the importance of metal/topological insulator interfaces characterization taking into account the possibility of a chemical reaction with all of its consequences. Results should be considered for future theoretical and applicative studies involving such interfaces as well as for the possible engineering of 2D TI heterostructures.
