Porous silicon carbide monoliths were obtained using the infiltration of preformed SiO2 frameworks with appropriate carbon precursors such as mesophase pitch. The initial SiO2 monoliths possessed a hierarchical pore system, composed of an interpenetrating bicontinuous macropore structure and 13 nm mesopores confined in the macropore walls. After carbonization, further heat treatment at ca. 1400 degrees C resulted in the formation of a SiC-SiO2 composite, which was converted into a porous SiC monolith by post-treatment with ammonium fluoride solution. The resulting porous SiC featured high crystallinity, high chemical purity and showed a surface area of 280 m(2) g(-1) and a pore volume of 0.8 ml g(-1)
It has often been pointed out that there is some overlap between epistemic modality and evidentiality (Chafe & Nichols 1986, Cornillie 2007, De Haan 1999, Dendale & Tasmowski 2001, Plungian 2001, Squartini 2004). In this paper I would like to offer several reflections about the necessity of drawing a boundary between modality and evidentiality. Starting from the typological category of evidentiality - extended here for use in pragmatic studies - I will then explore demarcation problems in Romance languages, which lack grammaticalized forms for expressing evidentiality. The underlying premise of this paper is that evidentiality as marker of the origin of the speaker's knowledge stands in relation to the speaker's pragmatic stance. Because the perspective of the speaker is thus incorporated into the utterance, it seems appropriate to analyse the applicability of the deictic category. Finally, under the aspect of deixis, I shall attempt a demarcation between evidentiality and modality.
In recent years the category of evidentiality has come into use also for the description of Romance languages. This has been contingent on a change in its interpretation from a typological category to a semantic-pragmatic category, which allows an application to languages lacking specialised morphemes for the expression of evidentiality. In the following we will first describe the theoretical framework in which we use the category of evidentiality for the description of Romance languages. A key question to be elucidated here will be the determination of evidentiality as a deictic phenomenon. This will also be the basis for discussing the distinction between evidentiality and epistemic modality.
