Recupero di un'area dismessa a Siracusa
2010
The article describes the proposed redevelopment of a derelict industrial zone in Siracusa, through interventions on ten buildings destined to become tourist and hotel accommodation. The types of installation, materials and buildings techniques to be employed will render the proposed salvage operation sustainable, along with innovative technology and bio-architecture, the use of renewable energy source, all in accordance with the principle of energy-saving.

Developing Tele-Operated Laboratories for Manufacturing Engineering Education
2010
The aim of the PeTEX-project is to establish an e-Learning platform for the development, implementation, and delivery of educational training programs in the field of manufacturing engineering. The PeTEX team designs both: a technical platform for eLearning based on “Moodle” including distributed tele-operated experimentation facilities, and didactic and socio-technical requirements for a successful online learning community. User interfaces are deployed for remote access to instruments, data analysis and multiplexed data access via network protocols. Hence, the platform provides complex tools in order to perform various activities to support the educational process, from telemetric experim…
Accessibilità e fruibilità dei centri storici: un’opportunità per il Restauro
2020
L’eguaglianza di tutti, nel rispetto delle diversità, è un diritto costituzionale e contempla anche il diritto di tutti alla trasmissione di quei valori dell’architettura storica, riconosciuti e tutelati dal restauro. Valori che sono patrimonio collettivo, da conservare, trasmettere e fruire sia per le generazioni future che per quelle attuali. È difficile, quindi, pensare ad “una legge, o ad una teoria che voglia tutelare il monumento e non le persone, ad una cultura che prescinda dall’uso nel senso più ampio del termine”. Difatti, a distanza di trent’anni dall’emanazione in Italia della legge 41 del 1986, per l’introduzione dei Piani di Eliminazione delle Barriere Architettoniche (PEBA) e…
Rigenerazioni
2016
L’Architettura contemporanea, potrà misurarsi agevolmente con i luoghi del ‘già costruito’ a patto e a condizione che siano scelte le corrette tecnologie del fare "reversibile", senza mai snaturare le preesistenze. Una tale metodologia porterà a costi più bassi di qualsiasi altro tipo d’intervento di riuso e, non ultimo, potranno essere abbattuti i tempi di recupero, ma ancor più si attuerà la possibilità di dismettere il nuovo e di ri-recuperare ogni singolo componente utilizzabile per altri interventi in altri contesti, e questo solo attraverso una nuova e corretta ri-generazione a partire da una tecnologia al passo con la modernità in continua evoluzione.
Sustainable Recycling of Insoluble Rust Waste for the Synthesis of Iron-Containing Perovskite-Type Catalysts
2019
Insoluble rust waste from the scraping of rusted iron-containing materials represents a cheap, eco-friendly, and available source of iron. LaFeO3 perovskite-type powders were successfully prepared by solution combustion synthesis using rust waste from an electricity transmission tower manufacturer. Solution combustion synthesis enabled introduction of this insoluble iron precursor directly into the final product, bypassing complex extraction procedures. Catalytic activity in the propylene oxidation of the waste-derived LaFeO3 with stoichiometric Fe/La ratio was almost identical to the commercial iron nitrate-derived LaFeO3 , thus demonstrating the viability of this recycling solution. The a…
Temporal control of xyloglucan self-assembly by radiation-induced degradation
2016
Xyloglucan is a natural polysaccharide present as storage material in seeds and structural materials in the primary cells walls of higher plants. Xyloglucan from tamarind seed is composed of B(1,4)-D-glucan backbone, partially substituted by a-(1,6)-linked xylose units, some of which are B-D-galactosylated at O-2. In its native form the polymer is water-soluble and forms gel in the presence of moderate amounts of alcohols. When a given fraction of galactosyl residues are removed, the polymer acquires the ability to form gels in aqueous solution at physiological temperatures, a property of great interest for biomedical/pharmaceutical applications. Gelation on increasing temperature can be as…
