FRANZ BRENTANO ET LE PRINCIPE DE RÉFÉRENCE INTENTIONELLE

In this thesis, I show in what way Brentano’s notion of intentionality is tied to a form of Platonising Aristotelianism. For both his mereological theory and his theory of knowledge depend on this Platonic element. In the first part, I show that the notion of intentionality is present as early as the dissertation On the Several Senses of Being in Aristotle (1862) in which Brentano takes up the ontological distinction between ‘in itself’ and ‘in the other’ which is of Platonic rather than Aristotelian stamp, in order to deduce from it, according to a single principle, the Aristotelian categories

Objeto e Correlato Intencional: De Brentano a Marty

The aim of this article is to amend some misunderstandings about Franz Brentano's thesis of intentionality, defending a different interpretation from the current one about the nature of intentional object and intentional correlate, and proposing an analysis of the origin of this conceptual confusion. The main problem lies in his student Anton Marty's interpretation of the immanent object, paving the way for an immanentist reading of Brentano's theory of intentionality.O objetivo deste artigo é retificar alguns mal-entendidos sobre a tese da intencionalidade de Franz Brentano, defendendo uma interpretação diferente da interpretação atual acerca da natureza do objeto intencional e do correlato intencional e propondo uma análise da origem desta confusão conceptual: o problema major está na interpretação que seu aluno Anton Marty faz do objeto imanente, abrindo caminho para uma leitura imanentista da teoria da intencionalidade de Brentano

Microstructural, thermo-mechanical and corrosion properties of electrophoretically co-deposited Cu and Fe doped Mn–Co spinel coatings for solid oxide cell interconnects

Chromia forming ferritic stainless steels are employed as interconnects in SOC stacks; the deposition of a manganese cobalt spinel protective coating is widely accepted as a viable solution to mitigate both the oxidation and the chromium evaporation. Electrophoretic deposition (EPD) offers the possibility to deposit homogeneous coatings in few seconds and at room conditions and the need of a simple and adaptable apparatus, thus reducing processing time and cost. A successful deposition is ensured by the optimization of both the starting suspensions in terms of colloidal properties and the post-deposition sintering profile. Electrophoretic co-deposition is an innovative approach for the simultaneous deposition of spinel precursors and for designing in-situ modified manganese-cobalt spinel coatings. A systematic microstructural, thermo-mechanical and electrical characterization of simultaneous Fe–Cu doped Mn–Co spinel coatings processed by electrophoretic co-deposition on Crofer22APU is here reported and discussed. We demonstrate the feasibility to co-deposit Fe2O3, CuO and Mn–Co spinel to produce dense, stable and effective doped spinel coatings. Improved functional properties of produced coatings are assessed in terms of microstructure development, oxidation kinetics and area specific resistance at SOC stack relevant conditions. Furthermore, an assessment of the dilatometric properties of the Fe–Cu doped spinels reveals the influence of different doping levels on the thermomechanical compatibility of the Fe–Cu doped Mn–Co spinel coatings with the interconnect. This work proposes the electrophoretic co-deposition method as an innovative approach for the simultaneous deposition of spinel precursors and for designing in-situ modified coatings

Highly Porous Polymer-Derived Bioceramics Based on a Complex Hardystonite Solid Solution

Highly porous bioceramics, based on a complex hardystonite solid solution, were developed from silicone resins and micro-sized oxide fillers fired in air at 950 °C. Besides CaO, SrO, MgO, and ZnO precursors, and the commercial embedded silicone resins, calcium borate was essential in providing the liquid phase upon firing and favouring the formation of an unprecedented hardystonite solid solution, corresponding to the formula (Ca0.70Sr0.30)2(Zn0.72Mg0.15Si0.13) (Si0.85B0.15)2O7. Silicone-filler mixtures could be used in the form of thick pastes for direct ink writing of reticulated scaffolds or for direct foaming. The latter shaping option benefited from the use of hydrated calcium borate, which underwent dehydration, with water vapour release, at a low temperature (420 °C). Both scaffolds and foams confirmed the already-obtained phase assemblage, after firing, and exhibited remarkable strength-to-density ratios. Finally, preliminary cell tests excluded any cytotoxicity that could be derived from the formation of a boro-silicate glassy phase
