X-ray absorption spectroscopy analysis: in situ, operando, in vivo
Iztok Arčon, 2020, published scientific conference contribution abstract (invited lecture)

Abstract: X-ray absorption spectroscopy (XAS) is a powerful tool for characterisation of local structure and chemical state of selected elements in different new functional materials and biological or environmental samples. The XAS spectroscopy is based on extremely bright synchrotron radiation X-rays sources, which allow precise characterisation of bulk, nanostructured or highly diluted samples. With its two methods (XANES and EXAFS) it enables monitoring changes in valence states and local structures of constituent elements during chemical reactions under controlled reaction conditions, and it offers a possibility of a combination of X-ray spectroscopy and microscopy with sub-micron lateral resolution, crucial for analysis of biological samples on sub-cellular level. In this talk some typical examples of advanced XAS analysis will be presented.

Spectroscopic insights into the electrochemical mechanism of rechargeable calcium/sulfur batteries

Abstract: Calcium batteries represent a promising alternative to lithium metal systems. The combination of the low redox potential and low cost and the energy-dense calcium anode (2073 mAh/cm3, similar to 2044 mAh/cm3 for Li) with appropriate low-cost cathode materials such as sulfur could produce a game-changing technology in several fields of applications. In this work, we present the reversible activity of a proof-of-concept Ca/S battery at room temperature, characterized by a surprising medium-term cycling stability with low polarization, promoted by the use of a simple positive electrode made of sulfur supported on an activated carbon cloth scaffold, and a state-of-the-art fluorinated alkoxyborate-based electrolyte. Insights into the electrochemical mechanism governing the chemistry of the Ca/S system were obtained for the first time by combining X-ray photoelectron spectroscopy and X-ray absorption spectroscopy. The mechanism implies the formation of different types of soluble polysulfide species during both charge and discharge at room temperature, and the formation of solid CaS at the end of discharge. The reversible electrochemical activity is proven by the reformation of elemental sulfur at the end of the following charge. These promising results open the way to the comprehension of emerging Ca/S systems, which may represent a valid alternative to Mg/S and Li/S batteries.

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

Hashem Bordbar, 2018, original scientific article

Abstract: The notion of the uni-soft idea is introduced, and related properties are investigated. Characterizations of the uni-soft ideal are discussed. The transfer of uni-soft ideal is considered, and relations between the uni-soft ideal and its transfer are investigated. Given a soft set, conditions for the transfer of soft set to be a uni-soft ideal.
Keywords: Coresiduated lattice, uni-soft ideal, transfer, support.

On the Distribution of Imperfective Suffixation and the Position of Theme Vowels in Slovenian
Vesna Plesničar, published scientific conference contribution abstract

Abstract: 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).

Molecular alignment on graphene surface determines transport properties of graphene/organic semiconductor transistors
Gvido Bratina, Egon Pavlica, Vadym Tkachuk, 2020, original scientific article

Abstract: Graphene field-effect transistor structures were used to investigate the role of molecular alignment on charge transport properties of heterostructures comprising a single-layer graphene and variable thickness of N,N′-bis(n-octyl)-(1,7&1,6)-dicyanoperylene-3,4:9,10-bisdicarboximide (PDI8-CN2) - an n-type organic semiconductor. Our atomic force microscopy data show that under selected growth conditions PDI8-CN2 grows in a layer-by-layer fashion up to a second monolayer. The first layer comprises flat-lying molecules, whereas the molecules in the second layer orient themselves in an upright orientation. Transconductance measurements show that the flat-lying molecules have little effect on the position of the Fermi level in graphene. Upright oriented molecules in the second layer instead, have a strong effect as to neutralize native p-type doping of graphene and cause a shift of charge-neutrality level towards the Dirac point. We interpret such behavior in terms of different orientation of the surface dipole on layers with different molecular orientations. At the same time the overall mobility of the charge carriers reaches values exceeding 3000 cm2/Vs.
