4592. Two “many”-words in Slovenian : Experimental evidence for pragmatic strengtheningPenka Stateva, Arthur Stepanov, 2017, 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.

4598. FROM SPINODAL DECOMPOSITION AND MOLECULAR DISPERSION OF POLYSILANES TO SUPER-HARD NANOCOATINGArtem Badasyan, Boštjan Mavrič, Matjaž Valant, objavljeni povzetek znanstvenega prispevka na konferenci 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]. Ključne besede: Polysilane, dendrimer, solubility Objavljeno v RUNG: 12.09.2017; Ogledov: 4370; Prenosov: 0 Gradivo ima več datotek! Več... |
