Modern American Literature in Italian Magazines during the 1930s
No full textThe article examines American fiction in Italian big magazines during the 1930s both in quantitative and qualitative terms, focusing on networks of circulation, production and reception. Analyzing not only American high modernism but also middlebrow and genre fiction, the article demonstrates how American litera- ture in weekly publications conflicted with traditional cultural values and Fascist monitoring and censoring, and how it was instrumental to Italian social and cultural modernity
I Vangeli dei Popoli. La Parola e l'immagine del Cristo nelle culture e nella storia [catalogo della mostra: Città del Vaticano, Palazzo della Cancelleria, 21 giugno - 10 dicembre 2000]
No full textCatalogo della mostra di manoscritti e stampati antichi (della Biblioteca Vaticana e di altre biblioteche italiane e straniere) della Sacra Scrittura e dei Vangeli in particolare. L'esposizione è stata organizzata in collaborazione con il Ministero per i Beni e le Attività Culturali italiano, e fa parte di un ciclo di mostre celebrative del Grande Giubileo dell'anno 2000. I materiali esposti documentano le tradizioni testuali e miniatorie della Sacra Scrittura presso le diverse civiltà scrittorie e artistiche: ciò attraverso l'esposizione di manoscritti e stampati greci, latini (o in alfabeto latino) e orientali
La versione armena
No full textIl contributo, dopo un'introduzione generale alla diffusione del cristianesimo nel mondo armeno e alla traduzione della Bibbia ("La Bibbia e i Vangeli nel mondo armeno"), passa a considerare i manoscritti armeni della Bibbia e dei Vangeli in possesso della Biblioteca Vaticana ("La Bibbia e i Vangeli armeni della Biblioteca Apostolica Vaticana"), descrivendone le principali caratteristiche e soffermandosi in particolare sulla loro decorazione
Growth Mechanism of Cluster-Assembled Surfaces : From Submonolayer to Thin-Film Regime
No full textNanostructured films obtained by assembling preformed atomic clusters are of strategic importance for a wide variety of applications. The deposition of clusters produced in the gas phase onto a substrate offers the possibility to control and engineer the structural and functional properties of the cluster-assembled films. To date, the microscopic mechanisms underlying the growth and structuring of cluster-assembled films are poorly understood, and, in particular, the transition from the submonolayer to the thin-film regime is experimentally unexplored. Here we report the systematic characterization by atomic force microscopy of the evolution of the structural properties of cluster-assembled films deposited by supersonic cluster beam deposition. As a paradigm of nanostructured systems, we focus our attention on cluster-assembled zirconia films, investigating the influence of the building block dimensions on the growth mechanisms and roughening of the thin films, following the growth process from the early stages of the submonolayer to the thin-film regime. Our results demonstrate that the growth dynamics in the submonolayer regime determines different morphological properties of the cluster-assembled thin film. The evolution of the roughness with the number of deposited clusters reproduces the growth exponent of the ballistic deposition in the 2 thorn 1 model from the submonolayer to the thin-film regime
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Cluster-Assembled Materials: From Fabrication to Function
No full textThe deposition of preformed clusters on a substrate enables the careful control of the nanoscale topography of thin films and hence the tuning of the structural and functional properties of nanostructured surfaces and interfaces. In this article, we show that cluster beam deposition (CBD) is an effective bottom-up approach for the engineering of nanostructured thin films with tailored properties. As a prototypical example of the possibilities offered by CBD, we present and discuss in detail how fabrication parameters affect the functional properties of very important systems such as titania, zirconia, and silicon nanostructured films. The use of pulsed microplasma and magnetron cluster sources allows the control of the characteristics of the building blocks and hence of the reproducibility of the deposition process and the functional properties of the cluster-assembled systems.
We discuss the implications of these mechanisms on the possibility of predicting and controlling the properties of cluster-assembled surfaces, presenting examples of applications where nanoscale morphology has a strong and direct impact on the physical behavior of the surface
Nanomanufacturing of titania interfaces with controlled structural and functional properties by supersonic cluster beam deposition
No full textGreat emphasis is placed on the development of integrated approaches for the synthesis and the characterization of ad hoc nanostructured platforms, to be used as templates with controlled morphology and chemical properties for the investigation of specific phenomena of great relevance in interdisciplinary fields such as biotechnology, medicine, and advanced materials. Here, we discuss the crucial role and the advantages of thin film deposition strategies based on cluster-assembling from supersonic cluster beams. We select cluster-assembled nanostructured titania (ns-TiO2) as a case study to demonstrate that accurate control over morphological parameters can be routinely achieved, and consequently, over several relevant interfacial properties and phenomena, like surface charging in a liquid electrolyte, and proteins and nanoparticles adsorption. In particular, we show that the very good control of nanoscale morphology is obtained by taking advantage of simple scaling laws governing the ballistic deposition regime of low-energy, mass-dispersed clusters with reduced surface mobility
