Two “many”-words in Slovenian
Arthur Stepanov, Penka Stateva, 64, izvirni znanstveni članek

Opis: 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.

Pobude za tretji pas na odseku avtoceste Vrhnika - Razdrto do leta 2025, za razširitev vseh slovenskih avtocest in hitro progo Nova Gorica - Ptuj
Zoran Božič, druga izvedena dela

Opis: Dopolnjena in razširjena pobuda za tretji pas na primorki, tokrat naslovljena na vlado Republike Slovenije. Pobude upoštevajo povečanje prometne mobilnosti in zmanjšanje pretočnosti, vključujejo pa tudi skrb za trajnostni razvoj in samooskrbo prebivalstva s hrano.

Role of transport band edge variation on delocalized charge transport in high-mobility crystalline organic semiconductors
Gvido Bratina, Andrey Kadashchuk, Egon Pavlica, Fei Tong, 2017, izvirni znanstveni članek

Opis: We demonstrate that the degree of charge delocalization has a strong impact on polarization energy and thereby on the position of the transport band edge in organic semiconductors. This gives rise to long-range potential fluctuations, which govern the electronic transport through delocalized states in organic crystalline layers. This concept is employed to formulate an analytic model that explains a negative field dependence coupled with a positive temperature dependence of the charge mobility observed by a lateral time-of-flight technique in a high-mobility crystalline organic layer. This has important implications for the further understanding of the charge transport via delocalized states in organic semiconductors.

Opis: Conformations of polymer molecules in solution crucially depend on the sign of the effective potential energy of interaction between the monomers, also known as the quality of solvent. Therefore in “poor” solvent regime, when effective attraction overwhelms, the experimental measurements of polymer sizes are complicated by the agglomeration of macromolecules, followed by precipitation. This phenomenon, also known as spinodal decomposition, causes serious problems when the goal is to determine properties of individual macromolecules. Interestingly, while in the case of carbon-based polymers the precipitation-related problems can be easily avoided with dilution, this is not the case for polysilanes, i.e. polymeric chains on basis of silicon. Although the linear polysilanes were first synthesized in early 1920’s, the aggregationrelated problems have hampered their studies and applicability until recently. In the Materials Research Laboratory of University of Nova Gorica we have developed a technology to strengthen the scratch-resistance nanocoating for glass on the basis of polysilane dendritic polymers we synthesized. Through the prism of the Flory-Huggins theory, that provides a miscibility phase diagram in temperature-volume fraction variables, the quality of polymer solution can be manipulated by changing the temperature. Using Dynamic Light Scattering (DLS) and Differential Scanning Calorimetry (DSC) we have managed to show, that at temperatures in the range of 40- 50 C the deagglomeration of the dendritic polysilane takes place in tetrahydrofuran (THF) [1], and the system becomes a true molecular dispersion with particles 20 nm in size [2]. Introducing such molecular dispersion into the alumina precursor solution yields an amorphous nanocomposite stabilized by a high level of strain. This resulted in an extraordinary increase of hardness and scratch resistance of the alumina – polymer nanocomposite coating that can be used for glass protection [3].
