1401. Lowest theme vowels or highest roots? : an ‘unaccusative’ theme-vowel class in SlovenianMarko Simonović, Petra Mišmaš, 2022, original scientific article Abstract: This paper focuses on the e/i theme vowel class of verbs in Slovenian to bring together two seemingly unrelated debates: (i) the debate on the correlation between theme-vowel classes and certain argument structures and (ii) the debate on the status of derivational affixes within the framework of Distributed Morphology. Our core data come from a list of 108 unaccusative verbs obtained using adjectival active l-participles as an unaccusativity diagnostic. We show that (i) no unaccusative verbs belong to the two largest theme-vowel classes in Slovenian (a/a and i/i), whereas (ii) the two big theme vowel classes tend to get accusative arguments quite frequently. Most importantly, (iii) the e/i class stands out since more than one half of the unaccusative sample falls into it. The e/i class is furthermore exceptional in that its theme vowel surfaces in adjectival l-participles, it is the theme-vowel class to which inchoatives in inchoative-causative pairs belong and it behaves uniformly with respect to stress. Based on this behavior, which sets the e/i-class apart from other theme-vowel classes, we argue that the morpheme e/i is better analyzed as a derivational affix. We further argue, following Lowenstamm (2014), that derivational affixes are transitive roots rather than categorizers and propose detailed PF and LF instructions for the root under consideration.

1410. Electrolysis energy efficiency of highly concentrated FeCl[sub]2 solutions for power-to-solid energy storage technologyUroš Luin, Matjaž Valant, 2022, original scientific article Abstract: An electrochemical cycle for the grid energy storage in the redox potential of Fe involves the electrolysis of a highly concentrated aqueous FeCl2 solution yielding solid iron deposits. For the high overall energy efficiency of the cycle, it is crucial to maximize the energy efficiency of the electrolysis process. Here we present a study of the influence of electrolysis parameters on the energy efficiency of such electrolysis, performed in an industrial-type electrolyzer. We studied the conductivity of the FeCl2 solution as a function of concentration and temperature and correlated it with the electrolysis energy efficiency. The deviation from the correlation indicated an important contribution from the conductivity of the ion-exchange membrane. Another important studied parameter was the applied current density. We quantitatively showed how the contribution of the resistance polarization increases with the current density, causing a decrease in overall energy efficiency. The highest energy efficiency of 89 ± 3% was achieved using 2.5 mol L−1 FeCl2 solution at 70 °C and a current density of 0.1 kA m−2. In terms of the energy input per Fe mass, this means 1.88 Wh g−1. The limiting energy input per mass of the Fe deposit was found to be 1.76 Wh g−1.
