Abstract: Photoconductivity spectra measured in non-crystalline corannulene thin layers are compared to optical absorption in solution phase and thin films. The unexpected enhanced photoconductivity is correlated with GW–BSE theoretical predictions of corannulene gas-phase excitonic spectra. Theoretical analysis reveals a consistent contribution involving transitions to Super Atomic Molecular Orbitals (SAMOs), a unique set of diffuse orbitals typical of curved conjugated constructs. Results suggest SAMO population via direct photoexcitation as a potential mechanism towards exploiting these diffuse orbitals as conducting channels in suitably assembled quantum nanostructures or solids.

Abstract: Slovenian features at least two lexical items that are potential semantic counterparts of the English many, namely "veliko" and "precej", whose meaning appears close to identical. Yet speakers are certain that the two items are not equivalent, although they find intuitively felt differences hard to pinpoint. We argue that "precej" and "veliko" are lexically synonymous, but their meanings are pragmatically strengthened under relevant conditions, which leads to subtle interpretative differences. Specifically, we extend Krifka’s (2007) analysis of double negatives and propose that "veliko" is assigned the stereotypical interpretation of a quantity degree word, whereas "precej" is identified with the non-stereotypical one and consequently relates to moderately big amounts. To support this claim, we report the results of an experiment involving a sentence-picture verification task, which highlight the similarities and contextually determined differences in the use of both determiners. Our results suggest that the interpretation of "precej" is not consistent with relations in the upper part of the proportional scale and is dependent on whether or not it is in direct competition with "veliko" in the appropriate contexts.
