El idealismo trascendental kantiano y sus primeros críticos
No full textEste trabajo propone considerar la discusión inicial acerca del concepto idealismo trascendental tal como Kant lo presenta en la primera edición de la Crítica de la razón pura como el momento inicial en el debate que da origen al movimiento usualmente denominado Idealismo alemán. Para ello se expone la noción de idealismo trascendental según Kant y se analizan tres interpretaciones de esta doctrina, muy diferentes entre sí y sumamente influyentes no sólo para la posterior recepción de la obra sino también para el desarrollo ulterior de la filosofía kantiana: los comentarios que Christian Garve y Johann Georg Feder, Hermann Andreas Pistorius y Friedrich Heinrich Jacobi publicaron entre 1782 y 1787. Estos pensadores consideraron al idealismo trascendental como el núcleo fundamental de la filosofía kantiana y formularon objeciones contra esa doctrina que, por un lado, obligaron a su autor a revisar y replantearse su posición y, por el otro, pusieron en el centro de la discusión el concepto de idealismo, su significado y sus consecuencias.Fil: Sole, Maria Jimena.

El dogmatismo consecuente es un idealismo: Fichte ante Spinoza en las Introducciones a la Doctrina de la Ciencia
No full textLa contraposición dogmatismo-idealismo articula el desarrollo argumental de la Primera y Segunda Introducción a la Doctrina de la Ciencia (EE y ZE). Fichte comienza estableciendo que ambos sistemas son válidos, para mostrar luego que únicamente el idealismo puede resolver la tarea de la filosofía. Pero la imposibilidad de convencer al dogmático de su error y la idea de que la filosofía que se adopta depende del tipo de ser humano que cada uno es, conducen a Fichte a sostener que para ser idealista hay que haber nacido idealista, haber sido educado y educarse para ello. El dogmático parece condenado a vivir y morir en su obstinación. El objetivo de este trabajo es mostrar que ese planteo se quiebra hacia el final de la ZE, en el momento en que Fichte aborda el caso del spinozismo. La discusión con Spinoza, enmarcada en el problema de la fuente de la convicción filosófica, revela que Fichte considera (a) que el dogmatismo puede alcanzar parcialmente la verdad; (b) que todo filósofo dogmático consecuente es en definitiva idealista, aunque no lo sepa y (c) que no sólo es posible dejar de ser dogmático y transformarse en idealista, sino que éste parece ser el camino que naturalmente sigue todo ser humano. Según mi lectura, entonces, el resultado de esta breve discusión con el spinozismo transforma por completo la concepción del dogmatismo que Fichte había ofrecido hasta ese momento así como su relación con el idealismo, y permite repensar la estrategia del idealista frente al dogmático.Fil: Sole, Maria Jimena.

Metal nanostructures decorated with silver nanostars: a novel highly efficient SERS substrate for dyes and pigments detection
No full textThe detection of artistic molecules such as dyes and/or pictorial binders employed in the field of Cultural Heritage requires more and more sensitive techniques. The surface enhanced Raman spectroscopy (SERS) represents a valuable option due to its ability to reveal molecules adsorbed or bound onto nanostructured interfaces. In order to maximize the enhancement of the Raman effect, different Ag and Au nanomaterials where bound together to produce hierarchical structures. In particular, silver nanostars (AgNSs) were chosen because of the strong enhancement caused by their anisotropic shape and they were prepared by one-pot chemical synthesis [1]. The AgNSs were used to decorate two different gold nanostructures, namely Au nanowires (AuNWs) and sphere segment void (SSV) structured surfaces. The AuNWs were obtained in the shape of ensembles of nanoelectrodes by templated elecrtroless deposition in nanoporous membranes [2,3] while the SSV substrates were prepared via gold electrodeposition by using a monolayer of polystyrene spheres as template [4].
The enhancement of the Raman effect was tested at first through the employment of benzenethiol, a well known Raman probe. Thereafter, cochineal lake-pigment, in particular, was chosen as target owing to its use throughout the history of art. Lakes are complex coloring pigments in which an organic dye (e.g. cochineal, madder or kermes) is adsorbed onto solid particles of inorganic salts. This composite structure, composed by an organic molecule chelated by metallic ions, makes the Raman detection of lakes extremely challenging. However, the described issue is overcome by employing highly sensitive SERS substrates as those prepared in the context of this thesis.
We compared the magnitude of the enhancements obtained with different SERS substrates: standing alone AgNSs, AuNWs ensembles and SSV substrates and hierarchical nanostructures composed by AgNSs combined to AuNWs (AgNSs@AuNWs) and to SSV substrates (AgNSs@SSV). Particularly strong enhancements were recorded in the case of the AgNSs@SSV substrates, showing the high potential of the so called particle-in-cavity (PIC) architectures [5]. Concluding, we synthesized highly effective hierarchical nanostructures whose future employment lies in the production of extremely sensitive SERS biosensors to be applied in the detection of artistic dyes and binders.

Istruzioni architettoniche fra Cinque e Seicento: da Carlo Borromeo a Vincenzo Maria Orsini
No full textCarlo Borromeo’s Instructions represent the only practical application of the Tridentine decrees in architecture. However, historians over time have given little weight to the work, which is mostly considered a simple parish handbook due to its practical-functional nature used to treat the sacred space. New research conducted on the literary work has focused on the massive diffusion of this treatise in the undergrowth of the ecclesiastical literature of the time, testifying to how much the Instructions are linked to the historical context and the spiritual needs of the post-Tridentine Church. The great novelty of the work lies in the fact that it completely overturned the way of writing about architecture. In the writings of Carlo Borromeo, a continuous interweaving between the doctrine of the soul and the sacred building is outlined to give the Church the image of an institution organically constituted in its material and spiritual reality. The influence of this work outside the Milanese context in which Carlo Borromeo worked is still to be clarified, especially in the South of Italy, which experienced the peak of its Counter-Reformation season between the seventeenth and eighteenth centuries. Here, Instructions will be analyzed along with the Antica Basilicografia of Pompeo Sarnelli (1686) and Il Rettore ecclesiastico of Marcello Cavalieri (1688), two writings born in the diocese of Benevento under the wing of the bishop Vincenzo Maria Orsini, a native of Gravina di Puglia
