Paolo Uccello a Bologna ovvero Carlo Volpe e Roberto Longhi in dialogo
No full textMuovendo dalla scoperta da parte di Carlo Volpe di un affresco di Paolo Uccello in San Martino a Bologna, il saggio discute il rapporto dialettico fra Volpe e Longhi tanto in per quanto riguarda il giudizio su Paolo Uccello quanto per quanto attiene la valutazione della pittura del Rinascimento a Bologn

Alder-ene addition of maleic anhydride to polyisobutene: nuclear magnetic resonance evidence for an unconventional mechanism
No full textIn this work, the thermal Alder-ene functionalization of highly reactive, vinylidene-terminated, polyisobutene (PIB) with
stoichiometric amounts of maleic anhydride at 200 ◦C was investigated by NMR spectroscopy. The thorough interpretation of
the complex NMR spectra of PIB derivatives collected at different reaction times (from 4 to 21 h) was based on the combined
use of one- and two-dimensional techniques which allowed the precise structure of all the reaction products as well as their
relative content to be ascertained. The analysis evidenced the formation of large amounts of derivatives generated by the
classic Alder-ene mechanism and involving the more reactive vinylidene ‘exo’ double bonds of PIB. More interestingly, the
investigation also the investigation allowed also to detect the formation of a noteworthy amount of not expected structure
generated by the thermalmaleination of the less reactive PIB ‘endo’ β-form provided by the isomerization of residual PIB ‘exo’ α-form during the functionalization reaction
Laser cleaning of pulsed laser deposited rhodium films for fusion diagnostic mirrors
No full textIn this paper an experimental investigation on the laser cleaning process of rhodium films, potentially candidates to be used as tokamak first mirrors (FMs), from redeposited carbon contaminants is presented. A relevant issue that lowers mirror's performance during tokamak operations is the redeposition of sputtered material from the first wall on their surface. Among all the possible techniques, laser cleaning, in which a train of laser pulses is launched to the surface that has to be treated, is a method to potentially mitigate this problem. The same laser system (Q-switched Nd:YAG laser with a fundamental wavelength of 1064-nm and 7-ns pulses) has been employed with three aims: (i) production by pulsed laser deposition (PLD) of Rh film mirrors, (ii) production by PLD of C deposits with controlled morphology, and (iii) investigation of the laser cleaning method onto C contaminated Rh samples. The evaluation of Rh films laser damage threshold, as a function of fluence and number of pulses, is discussed. Then, the C/Rh films have been cleaned by the laser beam. The exposed zones have been characterized by visual inspection and scanning electron microscopy (SEM), showing promising results

The Lettere of Andrea Calmo: authorial artifices and historical reality
No full textopenNonostante l’edizione di Vittorio Rossi del 1888, la raccolta di "ingegnosi cheribizzi" e di "fantastiche fantasie" di Andrea Calmo è ancora avvolta da un certo mistero. L’autore, dissimulando la propria identità dietro alla “maschera” dell’umile pescatore veneziano, è stato in grado di offrire uno spaccato della cultura e della società nella Venezia cinquecentesca.
In particolare, è il quarto libro delle Lettere ad aver suscitato maggiore interesse tra gli studiosi ed i lettori: pubblicato nel 1566, a diversi anni di distanza dai primi tre, questo libro si distingue per il fatto che tutte le epistole sono indirizzate a delle donne immaginarie o realmente esistite.
In questa sede si propone, in primo luogo, uno studio della biografia del Calmo accompagnata da un’analisi del contesto storico-culturale della Venezia cinquecentesca; in secondo luogo, invece, viene proposto un commento di alcune lettere dell’ultimo libro dell’opera calmiana, che cerchi di far luce principalmente sull’aspetto linguistico e contenutistico del testo.Despite Vittorio Rossi's 1888 edition, Andrea Calmo's collection of "ingegnosi cheribizzi" and "fantastiche fantasie" is still shrouded in a certain mystery. The author, dissimulating his own identity behind the "mask" of the humble Venetian fisherman, was able to offer a cross-section of culture and society in sixteenth-century Venice.
In particular, it is the fourth book of the Letters that has aroused greater interest among scholars and readers: published in 1566, several years after the first three, this book stands out for the fact that all the epistles are addressed to women imaginary or actually existed.
Here we propose, first of all, a study of Calmo's biography accompanied by an analysis of the historical-cultural context of sixteenth-century Venice; secondly, however, a commentary on some letters from the last book of Calmo's work is proposed, which seeks to shed light mainly on the linguistic and content aspect of the text
Multiscale morphology design of hybrid halide perovskites through a polymeric template
Full text linkHybrid halide perovskites have emerged as promising active constituents of next generation solution processable
optoelectronic devices. During their assembling process, perovskite components undergo very
complex dynamic equilibria starting in solution and progressing throughout film formation. Finding a
methodology to control and affect these equilibria, responsible for the unique morphological diversity
observed in perovskite films, constitutes a fundamental step towards a reproducible material processability.
Here we propose the exploitation of polymer matrices as cooperative assembling components of
novel perovskite CH3NH3PbI3 : polymer composites, in which the control of the chemical interactions in
solution allows a predictable tuning of the final film morphology. We reveal that the nature of the interactions
between perovskite precursors and polymer functional groups, probed by Nuclear Magnetic Resonance
(NMR) spectroscopy and Dynamic Light Scattering (DLS) techniques, allows the control of aggregates
in solution whose characteristics are strictly maintained in the solid film, and permits the formation of nanostructures
that are inaccessible to conventional perovskite depositions. These results demonstrate how the
fundamental chemistry of perovskite precursors in solution has a paramount influence on controlling and
monitoring the final morphology of CH3NH3PbI3 (MAPbI3) thin films, foreseeing the possibility of designing
perovskite : polymer composites targeting diverse optoelectronic applications
Trusted Tales: Creating Authenticity in Literary Representations from Ex-Yugoslavia
No full textThis research deals with questions of authority and authenticity and how they are expressed, constructed, and appropriated within the Anglophone book market. It considers the body of literature written about ex-Yugoslavia since the 1990s Balkan conflicts by exiled writers from the region which has entered the international literary canon. Books’ routes from original publishers into English translation are discussed through practices of trust, one of the crucial social devices underpinning their exchange. Within these cross-cultural processes, the role of cultural brokers is crucial. Symbolic and cultural resources are specifically mobilised through their powerful author brands.
By exploring authenticity in the context of book publishing, I further look at how ideas and practices of community are employed and negotiated by writers and those who promote their books. My field is multi-sited and fluid, reflecting how different individual and national positions are enacted and performed through strategies ranging from unconscious dispositions to deliberate intentions. This research thus brings together ideas of the author as an authentic, representative voice together with exile as a position that grants them a new lease of relevancy in the post-socialist context.
Although ex-Yugoslav books occupy a ‘high end’ niche of the UK market, constrained by commercial as well as political, cultural, and institutional forces, in public discourse ideas of the ‘free market’ and ‘free speech’ are mobilised to produce various types of modernisation narratives. The (post)socialist production of literature is perceived as having to ‘evolve’ into a capitalist model: this would allow not only healthy competition and consumer choice but guarantee an individual writer ‘free speech’ as a basic human right. Therefore, the most general question this research raises is what kind of foreign literature gets translated into English, under what socio-cultural conditions and which politics of representation it serves within the project of world literature
