BORDERSCAPES. Dalla difesa al dialogo. Reinventare gli spazi pubblici acquatici tra l’Arsenale e la città
Full text linkL'articolo racconta l'esperienza di workshop internazionale condotto congiuntamente dal Dipartimento di Architettura dell'Università di Firenze e il corrispondente dipartimento di Architettura (Laboratorio ville et paysage) dell'Università di Liegi con il coordinamento dei prof. Gabriele Paolinelli, Ludovica marinaro e Rita Occhiuto. Il workshop residenziale "Borderscape dalla difesa al dialogo" ha visto il gruppo di lavoro impegnato in un'esperienza progettuale immersiva nella città di Spezia a diretto confronto con il complesso tema della ricucitura delle relazioni tra Arsenale militare e città tramite la trasformazione, rigenerazione, e valorizzazione dello spazio pubblico di limite. Un bordo d'acqua, quello del canale Lagora e del lungo muro di cinta dell'Arsenale, denso di stratificazioni e significati che attende solo di essere ripensato. L'articolo narra l'esperienza laboratoriale che ha dato avvio ad una sperimentazione attiva replicata l'anno successivo a Liegi, e in corso di maturazione attraverso nuove riflessioni congiunte tra le due università

Investigation of the electrochemical behavior at low temperature and fast charge/discharge rate of anodic materials for lithium-ion batteries
No full textNowadays lithium-ion batteries represent the state-of-the-art of energy storage devices. Within this context the work herein presented deals with the investigation and the improvement of the electrochemical behavior of anode materials for lithium-ion batteries.\ud
Conductive agents play a fundamental role in determining the electrochemical performance of electrodes for lithium-ion batteries. Super-P carbon is often used in the\ud
electrode formulations in order to increase the electrical conductivity and to improve the contact between particles. In this work we synthesized a copper-modified Super-Pbased\ud
conductive agent, in which copper nanoparticles supported on the carbon matrix have been obtained by a microwave-assisted reduction of Cu (II) ions. The obtained\ud
copper/Super-P composite showed good dispersion of the nanoscaled copper particles on the carbon matrix. The synthesized conductive agent has been used instead of\ud
pristine Super-P during the manufacturing process of graphite and Li4Ti5O12 electrodes.\ud
Graphite is at the moment the most commonly used anode material in lithium-ion batteries. Unfortunately when graphite anodes are forced to work at low temperature\ud
and/or at high charge/discharge rate, the electrochemical performance drastically decreases. In this work electrodes made of oxidized KS-15 graphite (Timcal) have been tested at low temperature and high charge/discharge rate. Two different anodic formulations have been tested. Unmodified electrodes have been prepared using pristine Super-P as conductive agent. On the other hand, copper-modified ones have been manufactured with the synthesized copper/Super-P composite. It has been demonstrated that the use of the copper/Super-P composite in the electrode formulation leads to improved performances at low temperature (down to -30°C) and at increased charge/discharge rate. Furthermore, we propose a detailed study of the differential capacity curves dQ dE-1 vs. V and a set of experiments to investigate the electrical properties of the tested samples. The obtained results showed decreased polarization\ud
and increased electrical conductivity for copper-modified electrodes. The effect of both pristine Super-P and Cu/Super-P on anodes electrochemical behavior is explained by DC- and AC -electrical studies. The results show decreased electrical resistance and metallic-like behavior of the electronic conductivity as a function of the temperature on samples containing Cu/Super-P. It implies that when the temperature is decreased, the electrical conductivity linearly increases. Conversely, the sample containing pure Super-P follows a classical semi-conductor behavior, with the electrical conductivity decreasing with the decreasing temperature.\ud
Li4Ti5O12 is considered a safer alternative to carbonaceous anodes. The main disadvantages of LTO-based electrodes are related to the poor ionic and electronic conductivity of this compound, which determine poor rate capability and poor\ud
electrochemical performances at low-temperature. In this thesis we demonstrate that the use of the copper/Super-P composite instead of pristine Super-P positively affects the\ud
electrochemical behavior of the tested anodes. Electrodes manufactured starting from commercial LTO purchased from Aldrich, have been tested in the temperature range of\ud
-30≤ T≤ 20°C. The results demonstrate excellent performances of the copper-modified electrodes. Moreover, the rate capability and the cycling stability of the LTO electrodes have been remarkably improved by the use of copper/Super-P in the electrode composition.\ud
Rutile-TiO2 has been considered for a long time as almost inactive towards lithium insertion. Lately it has been proven that by controlling the particles size during its\ud
synthesis it is possible to reversibly insert a relevant amount of lithium ions into the rutile structure. In this work, nanoscaled rutile-TiO2 has been synthesized following a sol-gel procedure. The electrochemical tests performed on rutile electrode demonstrated the excellent electrochemical behavior at low temperature. Moreover, it has been\ud
demonstrated that rutile-TiO2 electrodes can be cycled within an enlarged potential window (0.1-3 Volts) in addition to the classical 1-3 Volts window of TiO2 system.\ud

The Montalbano Fortress, an early report about a lost fortification in the Gulf of La Spezia
Full text link[EN] The research proposed here is another tile that contributes to the documentation of the rich mosaic of modern fortifications of the Gulf of La Spezia counting on an extraordinary heritage of 42 buildings and many more accessory settlements built to defend the Maritime Military Arsenal at the end of the XIXth century. As part of a complex system that sprinkles the entire gulf, the former Montalbano fortress represents the central and biggest architecture of the landward front. The proposed contribution will bring to the attention the first report about the architecture and the landscape setup of the Montalbano Fortress, investigating its true extension and the articulation of its complex spaces, now hidden by the woods after its abandonment. The very large size, the overall good conditions of most of the buildings, and the wilderness due to a vegetal recolonization, make this settlement very interesting and challenging in terms of documentation, restoration, and reuse strategy as a public space for the city. This contribution will share and present the state of knowledge about this "lost" and neglected structure to prefigure an inclusive and sustainable process of landscape regeneration.Verdiani, G.; Marinaro, L.

Entre el apoyo y el enfrentamiento : El diario El Tribuno frente a la candidatura de Miguel Ragone
Full text linkEste artículo pretende examinar las políticas discursivas y el posicionamiento de la cúpula editorial del diario salteño El Tribuno durante la candidatura de Miguel Ragone (del cierre de las listas, el 2 de enero, al día de la votación, el 11 de marzo de 1973). Se evidencian dos momentos principales: una apatía política, debido a la interna partidaria y un posterior apoyo a la candidatura de Miguel Ragone, perteneciente al Partido Justicialista. Este apoyo estaba constituido por una particular forma enunciativa, una identificación con el mundo popular que legitimaba el posicionamiento a favor del candidato peronista. La estrategia populista se constituiría en una "garantía" discursiva que acompañaba a las acciones políticas concretas que tenían a su director como protagonista -incluso en un momento posterior en oposición a RagoneFil: Marinaro, Guillermo Salvador.

La batteria Valdilocchi alla Spezia, rilievo digitale e documentazione di un’architettura alla fine di un’epoca
Full text link[EN] All the fortifications have their time. They respond to specific way of defending and attacking they
change in time accordingly to the terrible habits of the weaponry and technology evolution. For a long
time, from the age of the great fortifications, to the use of cannons, to the invention of the aerial war,
the military built heritage have seen a long transformation made of sudden architectural changes, until
the moment when the possibility of bombing and attacking from the sky signed the sunset of the large
over ground buildings in favour of mimetic and underground structures. The “Valdilocchi Battery” belong to the last age of the large fortress, capable to resist to ground attack while showing the aspect of
an inexpugnable stronghold. Sited on the top of a hill in the eastern part of the La Spezia gulf, this battery had the function of second line defense to control the neighboring valleys. The particular pentagonal plant and the state of excellent preservation, except for a part of collapse on the front of the gorge
due to the German bombing, make it an artifact of great value.Verdiani, G.; Marinaro, L.; Reitano, D. (2020).
