Louisa S. McCord's Caius Gracchus: A Transatlantic Southern Literary Response to 1848 European Revolutions

2016

Louisa S. McCord is the most important female intellectual in the antebellum South and one of its most recognized voices, even if her name rarely appears in studies not directly related to her region. McCord has a parallel, according to Mary Kelley, in Margaret Fuller, the relevant prewar Northern intellectual and essayist. From contrasting ideological positions, both left testimony of their interest in constructing a model of womanhood, capable of facing the contingencies of their times. Born in one of the most influential families of South Carolina, McCord produced a phenomenal synthesis of the conservative political, economic and religious arguments accepted in her times and managed to t…

Crosslinked Sulfonated Poly(vinyl alcohol)/Graphene Oxide Electrospun Nanofibers as Polyelectrolytes

2019

[EN] Taking advantage of the high functionalization capacity of poly(vinyl alcohol) (PVA), bead-free homogeneous nanofibrous mats were produced. The addition of functional groups by means of grafting strategies such as the sulfonation and the addition of nanoparticles such as graphene oxide (GO) were considered to bring new features to PVA. Two series of sulfonated and nonsulfonated composite nanofibers, with different compositions of GO, were prepared by electrospinning. The use of sulfosuccinic acid (SSA) allowed crosslinked and functionalized mats with controlled size and morphology to be obtained. The functionalization of the main chain of the PVA and the determination of the optimum co…

In vitro validation of biomedical polyester-based scaffolds: Poly(lactide-co-glycolide) as model-case

2018

[EN] Monitoring and understanding the in vitro behaviour of polyester based scaffolds both comprising the study of the hydrolytic degradation and the cell seeding viability is essential to ensure the desired functionality, according to a given biomedical purpose. As a model case to compare the performance of techniques to monitor the in vitro behaviour, poly(lactide-co-glycolide) (PLGA) scaffolds were chosen. The in vitro hydrolytic degradation of PLGA scaffolds was carried out in water and phosphate buffered saline (PBS). The evolution of the mass loss, the molar mass, the thermal properties and the surface morphology were monitored. The hydrolytic degradation media was correspondingly eva…

Conductive polycaprolactone/gelatin/polyaniline nanofibres as functional scaffolds for cardiac tissue regeneration

2022

Abstract The endorsement of functional features such as biocompatibility, mechanical integrity, or electrical conductivity to tissue engineering (TE) scaffolds is essential to stimulate cell adhesion and proliferation. In this study, electrospun nanofibers based on polycaprolactone (PCL) and gelatin (Ge) (ratios 60/40, 50/50, and 40/60), and polyaniline (PAni) particles (0.25, 0.50, and 1.00%wt) were prepared. The time of dissolution in an acid solvent mixture before electrospinning allowed for obtaining nanofibers with controlled features. Changes in the molar mass (Mn from 90·103 to 15·103 g·mol−1), in the crystalline microstructure (Xc from 60 to 25%) and the surface morphology (diameter…

Francesco Pennisi. Invenzione e memoria

2017

Il volume riunisce alcuni scritti su e di Francesco Pennisi, con particolare riferimento ai rapporti del compositore con le sue memorie infantili, la Sicilia e la produzione poetica di Lucio Piccolo. In particolare vengono affrontati i temi legati alla genesi e alla struttura compositiva delle due "Canzoni natalizia etnee trascritte dalla memoria per 11 strumenti" op. 49 (1982-83) e dei riferimenti letterari dell'opera da camera "L'Esequie della luna" op. 79 (1991). Il saggio di Paolo Emilio Carapezza è invece dedicato alla produzione pianistica. Oltre a cinque testi di Francesco Pennisi, vengono proposte nel volume anche tre lettere inedite (1991) e lo spartito autografo di "Una Pastorale …

2007

Il quaderno nasce all'interno del progetto “Ritratti d’artista”, finanziato dal POR SICILIA 2000-2006 (sottomisura 2.02 azione d) e curato dall’associazione culturale CLAC – centro laboratorio arti contemporanee – per e con il Comune di Sortino. Il quaderno monografico raccoglie una serie di interventi critici e testimonianze sul poeta Lucio Piccolo di Calanovella. Testi di: Marta Barbaro, Fulvio Abbate, Maria Luisa Spaziani,Vincenzo Consolo, Andrea Cortellessa, Michele A.Purpura, Michela Sacco e Flora Di Legami

Lucio Piccolo. Mondo lirico

2006

Lo sconosciuto poeta Lucio Piccolo irrompe sulla scena letteraria italiana nel 1954, all’età di 51 anni, quando Eugenio Montale scopre quasi per caso i suoi Canti barocchi e decide di presentarli al convegno di San Pellegrino Terme. Il fascino musicale di quelle liriche piene di suggestioni letterarie e di immagini vivissime e la compagnia di un altro misterioso personaggio della colta nobiltà siciliana - il cugino Giuseppe Tomasi Principe di Lampedusa - conquistano immediatamente i più grandi scrittori e critici del momento. 
L’anziano ed eccentrico Cavaliere di Calanovella diventa all’improvviso un “caso” nazionale. Lucio Piccolo non si muove dalla campagna di Capo d’Orlando, nel messines…

Un favoloso narrare. "L'esequie della luna" di Lucio Piccolo.

2017

Il saggio analizza un racconto di Piccolo, L'esequie della luna, evidenziando l'intensità metaforica di una prosa le cui strategie espressive, liriche,analogiche, surreali, connotano la produzione in versi dello scrittore siciliano. Si tratta di una favola poetica che intesse storia,sogni e visioni, e, nel contempo, è declinata modernamente come gioco letterario con cui celare e svelare una personale visione della scrittura letteraria: allusiva e raffinata, ironica e favolosa.

Novel silicon microparticles to improve sunlight stability of raw polypropylene

2015

Oxidation of polyolefins by ultraviolet/visible irradiation is a significant limitation for their use in several technological applications. The use of high-tech additives such as silicon microparticles becomes a compositing strategy that can improve the performance of these materials at long-term service conditions. Silicon particles were added to non-additivated raw polypropylene (PP) prepared by hot melt extrusion and subjected to accelerated sunlight irradiation tests. The stability of thermal properties, mechanical performance and thermal decomposition behaviour of composites was evaluated by differential scanning calorimetry, dynamic mechanical thermal analysis and thermogravimetry.
