A lo largo de más de dos milenios los pensadores escépticos han compartido concepciones políticas semejantes. El hecho de que muchos de estos rasgos sean reconocibles en Borges refuerza la interpretación escéptica de su obra que he defendido en mi tesis doctoral y en diversos artículos. Analizaré, en primer lugar, la actitud política, conservadora, tradicionalmente asociada al escepticismo; en segundo lugar, el modo en que Borges participa de dicho conservadurismo progresista; y, en tercer lugar, aquellas características del pensamiento borgeano que pueden llevarnos a considerarlo como un intelectual según la definición que propone del mismo Edward W. Said en Representations of the intellectual.

The singular properties of hydrogenated amorphous carbon (a-C:H) thin filmsdeposited by pulsed DC plasma enhanced chemical vapor deposition (PECVD), such as hardness and wear resistance, make it suitable as protective coating with low surface energy for self-assembly applications. In this paper, we designed fluorine-containing a-C:H (a-C:H:F) nanostructured surfaces and we characterized them for self-assembly applications. Sub-micron patterns were generated on silicon through laser lithography while contact angle measurements, nanotribometer, atomic force microscopy (AFM), and scanning electron microscopy (SEM) were used to characterize the surface. a-C:H:F properties on lithographied surfaces such as hydrophobicity and friction were improved with the proper relative quantity of CH4 and CHF3 during deposition, resulting in ultrahydrophobic samples and low friction coefficients. Furthermore, these properties were enhanced along the direction of the lithographypatterns (in-plane anisotropy). Finally, self-assembly properties were tested with silicananoparticles, which were successfully assembled in linear arrays following the generated patterns. Among the main applications, these surfaces could be suitable as particle filter selector and cell colony substrate.
