Pietro da Eboli, De Euboicis aquis, ed. T. De Angelis
No full textIl De Euboicis aquis (già conosciuto con il nome di De balneis Puteolanis o De balneis Terrae Laboris) è un’opera del poeta Pietro da Eboli (1160 ca.-1220?). Si tratta di un poema medico-didascalico, composto da 31 epigrammi e molto probabilmente dedicato all’Imperatore Enrico VI di Svevia, nel quale il poeta celebra le proprietà curative delle fonti termali che si trovano sulla costa della Campania di fronte al golfo di Pozzuoli, sul territorio denominato Campi Flegrei

Design of Ru(II) sensitizers endowed by three anchoring units for adsorption mode and light harvesting optimization
No full textWe report the design, synthesis and computational investigation of a class of Ru(II)-dyes based on mixed bipyridine ligands for use in dye-sensitized solar cells. These dyes are designed to preserve the optimal anchoring mode of the prototypical N719 sensitizer by three carboxylic groups, yet allowing for tunable optimization of their electronic and optical properties by selective substitution at one of the 4-4′ positions of a single bipyridine ligand with π-excessive heteroaromatic groups. We used Density Functional Theory/Time Dependent Density Functional Theory calculations to analyze the electronic structure and optical properties of the dye and to investigate the dye adsorption mode on a TiO2 nanoparticle model. Our results show that we are effectively able to introduce three carboxylic anchoring units into the dye and achieve at the same time an enhanced dye light harvesting, demonstrating the design concept. As a drawback of this type of dyes, the synthesis leads to a mixture of dye isomers, which are rather tedious to separate
De Angelis difusor de Vico: examen de un paradigma indiciario
No full textEl autor trata de determinar si la recepción de G. Vico en el contexto de la cultura rioplatense decimonónica se debió directamente a De Angelis o Michelet, aparentemente influido a su vez por De Angelis. Si la primera idea es plausible, dada la estancia del mismo italiano en la Argentina, entonces la conclusión parece clara: el verdadero papel de De Angelis en la difusión decimonónica de Vico no es un hecho, sino algo desconocido. Sin embargo, el hecho de que algo no se encuentre mostrado por la evidencia documental no impide su existencia ficcional.The author tries to determinate if the reception of G. Vico in the context of the River Plate Culture of the nineteenth century was due directly to De Angelis, or to Michelet, apparently influenced in turn by De Angelis. If the first idea is plausible, through the stay of the Italian himself in the Argentine, then the conclusion seems clear: the true rôle of De Angelis in the spread of Vico in the nineteenth century is an unknown, and not a fact. However, the fact that something is not shown by documentary evidence does not prevent it being fictionally suppoused
Selective TDDFT with automatic removal of ghost transitions: application to a perylene-dye-sensitized solar cell model
No full textWe present an application of a selective time-dependent density-functional theory (TDDFT)
scheme to a model for a dye-sensitized solar cell (DSSC) with a perylene sensitizer dye on a
TiO2 nanoparticle model. In an earlier study on this system [De Angelis, Chem. Phys. Lett.,
2010, 493, 323], it was reported that a large number of conduction-band excitations severely
complicate the identification of the bright p - p* excitations of the perylene dye. Here, we show
that this problem can be overcome by applying a selective TDDFT solver based on a guess for
the relevant orbital transition in combination with a suitable root-homing scheme. In order to
enhance the efficiency of this algorithm we implement an automatic removal scheme for
artificially low-lying long-range charge-transfer transitions from the TDDFT eigenvalue problem.
A large number of such transitions appear in explicitly solvated systems in the form of
inter-solvent or solvent–solute transitions. We study the characteristics of this removal scheme for
a small water cluster and then apply it in a TDDFT calculation to a perylene–TiO2 nanoparticle
model system and to perylene explicitly solvated in methanol. It is demonstrated that this scheme
leads to a large reduction in the computational cost with essentially no loss in accuracy. Large
differences in the effect of adsorption on the excited states of perylene dyes with two different
anchor groups found in earlier work are confirmed.[Original citation, including DOI link to article on rsc.org] – Reproduced by permission of The Royal Society of Chemistr

Il Regno di Sicilia in età normanna e sveva. Forme e organizzazioni della cultura e della politica. Premessa. Politica e politiche culturali nell’età normanna e sveva
No full textIl Regno di Sicilia, in età normanna e sveva, costituisce una realtà politico-amministrativa unitaria, ma assai multiforme nei suoi compositi tratti etnici, sociali e territoriali. Con tale varietà i sovrani dell’Italia meridionale seppero confrontarsi, dando compiuta e piena dimostrazione delle loro qualità politiche e dei loro interessi intellettuali, delineando precisi indirizzi culturali e di governo. Se l’Università di Napoli, fondata nel 1224, rappresentò la piena espressione della volontà e della lungimiranza politica di un grande re e imperatore come Federico II, anche l’attività amministrativa fu un formidabile strumento di regolamentazione istituzionale e ideologica del Regno.Questo è il campo di indagine del presente volume che, in particolare, pone l’attenzione sulle strategie organizzative tanto della cultura quanto della politica. Esse culminarono certamente nei decenni dominati dall’eccezionale figura di Federico II, ma furono predisposte dai suoi immediati predecessori normanni e – proseguite compiutamente dai suoi figli Corrado e Manfredi – non furono del tutto scardinate neanche dai sovrani della dinastia angioina
