Questioni di principio. Pensare con Nunzio Incardona
2013
Words as beginning, ground, origin – the words of Incardona’s discourse – appear as terms of a speculative dictation that, far from tracing out the dogmatic pathway of a deductive development, instead feels the constant need to go backover its own steps, to re-examine itself each time according to an interrogationthat digs in its own assumptions, its starting positions.

Esperienze nel restauro del Moderno
2013
A partire dal XVI ciclo, il Dottorato di ricerca in Progettazione Architettonica di Palermo, Napoli, Parma e Reggio Calabria si è occupato del tema "La scienza del progetto nel restauro del moderno", indagando sulla comprensione dei temi più intimi del rapporto nuovo/preesistente e sulla logica dei principi strutturanti il progetto di architettura di qualità. Il progetto di architettura, principale protagonista del lavoro di ricerca, nell'approccio del dottorato è stato assunto come strumento di comprensione piuttosto che come capitolo conclusivo del percorso affrontato. Questo libro, in continuità con altre due pubblicazioni precedenti, dà conto degli esiti dell'attività di ricerca svolta …
Rule of Law e particolarismo etico
2016
Questo scritto è dedicato alla trattazione del problema se l’ideale del Rule of Law sia compatibile con il particolarismo etico. Sostengo che, nonostante l’apparenza, la risposta a questa domanda è affermativa. Prima di presentare i miei argomenti a favore di questa tesi è necessario (i) chiarire che cosa intendo per ‘Rule of Law’ e ‘particolarismo etico’ (parr. 2 e 3); (ii) spiegare perché mai ci si dovrebbe porre l’interrogativo se il Rule of Law sia o no compatibile con il particolarismo etico (par. 4); e infine (iii) chiarire perché la risposta a questo interrogativo sia apparentemente negativa (par. 4). A questo punto, presento i miei argomenti – tre – a sostegno della tesi della compa…
Pressure Retarded Osmosis: a Membrane Process for Environmental Sustainability
2016
Salinity Gradient Power (SGP) based on the controlled mixing between two solutions at different salinities is a viable alternative to produce power from renewable sources. Pressure Retarded Osmosis (PRO) is one of the most promising technologies proposed so far for the exploitation of such energy source. Apart from the typical source of salinity gradients, namely river water and seawater, more and more interest has been raised recently towards the use of non-conventional saline solutions. In this work, water originating from a sewage treatment plant is used as the dilute solution (feed solution), while brine exiting from a desalination plant is used as the concentrate (draw solution), thus …
Solution-Based Processing for Scaffold Fabrication in Tissue Engineering Applications: A Brief Review
2021
The fabrication of 3D scaffolds is under wide investigation in tissue engineering (TE) because of its incessant development of new advanced technologies and the improvement of traditional processes. Currently, scientific and clinical research focuses on scaffold characterization to restore the function of missing or damaged tissues. A key for suitable scaffold production is the guarantee of an interconnected porous structure that allows the cells to grow as in native tissue. The fabrication techniques should meet the appropriate requirements, including feasible reproducibility and time- and cost-effective assets. This is necessary for easy processability, which is associated with the large …
Novel dual-flow perfusion bioreactor for in vitro pre-screening of nanoparticles delivery: design, characterization and testing
2021
An advanced dual-flow perfusion bioreactor with a simple and compact design was developed and evaluated as a potential apparatus to reduce the gap between animal testing and drug administration to human subjects in clinical trials. All the experimental tests were carried out using an ad hoc Poly Lactic Acid (PLLA) scaffold synthesized via Thermally Induced Phase Separation (TIPS). The bioreactor shows a tunable radial flow throughout the microporous matrix of the scaffold. The radial perfusion was quantified both with permeability tests and with a mathematical model, applying a combination of Darcy's Theory, Bernoulli's Equation, and Poiseuille's Law. Finally, a diffusion test allowed to in…
Preparation and characterization of PLLA-HA scaffolds for bone tissue engineering
2013
In this work, the possibility to produce composite - Poly-L-lactic acid (PLLA) and Hydroxyapatite (HA) - porous scaffolds via Thermally Induced Phase Separation for bone tissue engineering applications was investigated. Several PLLA/HA ratios were tested (70/30, 50/50, 30/70 and 20/80 wt/wt) and the as-obtained scaffolds were characterized via Scanning Electron Microscopy (SEM), Wide Angle X-Ray Diffraction (WAXD) and compression test. The results showed that the presence of HA does not influence the phase separation process. Morphological analysis revealed an open structure with interconnected pores and HA embedded in the polymer matrix. This evidence was confirmed by WAXD analysis; where …
A COMPOSITE PLLA SCAFFOLD FOR REGENERATION OF COMPLEX TISSUES
2010
A composite biodegradable scaffold incorporating an integrated network of synthetic blood vessels was designed and prepared, in line with the requirements of a scaffold effectively supporting the regeneration of highly vascularized tissues. In other words, this composite scaffold should allow the regeneration of complex injured tissue (e.g. dermis) and, at the same time, favour the development of a vascular network on its inner, i.e. a 3D polymeric scaffolds embedding synthetic blood vessel-like structures for nutrient supply and metabolite removal. PLLA assures a high degree of biocompatibility and a low level of inflammation response upon implantation, while the embedded tubular vessel-li…
