The essentials of marine biotechnology
2021
Coastal countries have traditionally relied on the existing marine resources (e.g., fishing, food, transport, recreation, and tourism) as well as tried to support new economic endeavors (ocean energy, desalination for water supply, and seabed mining). Modern societies and lifestyle resulted in an increased demand for dietary diversity, better health and well-being, new biomedicines, natural cosmeceuticals, environmental conservation, and sustainable energy sources. These societal needs stimulated the interest of researchers on the diverse and underexplored marine environments as promising and sustainable sources of biomolecules and biomass, and they are addressed by the emerging field of ma…

A Solar Photothermocatalytic approach for the CO2 conversion: Investigation of different synergisms on CoO-CuO/Brookite TiO2-CeO2 catalysts
2022
Abstract The photoactive features of the least common polymorph of TiO2, i.e. brookite, were combined with the thermocatalytic redox ones of cerium oxide, focusing on the effects of the addition of small amounts of Co-Cu oxides for the solar CO2 conversion. By considering the characterization data, a surface segregation of the hosted metal oxides on the TiO2-CeO2 composite was evidenced, and their presence increased the amount of oxygen vacancies and improved the charge carriers separation. The bimetallic oxides-based sample was the most performing one in the photocatalytic carbon dioxide reduction at room temperature. The formation of carbon monoxide and methane was 5 and 0.5 μmol g−1h−1, …
PROTEGGERE E VALORIZZARE: RIFLESSIONI PER UNA BUONA PRATICA SUI SITI ARCHEOLOGICI
2014
Tra i beni culturali quelli archeologici hanno più animato il dibattito culturale sul rapporto fra conservazione e valorizzazione. La fragilità con cui la materia ci viene consegnata dalla storia, la frammentarietà del reperto, la scarsa disponibilità di risorse finanziarie, in relazione anche alla vastità del patrimonio a noi pervenuto, impongono interventi mirati e talvolta urgenti per la salvaguardia e la conservazione di tali beni. Ma la sola conservazione non può costituire l’obiettivo ultimo dell’intervento: essa deve interessare anche azioni di messa in valore, di fruizione e di comunicazione, necessarie per favorire un nuovo ruolo a queste realtà private dell’originaria identità. Qu…
A new strategy to maximize organic matter valorization in municipalities: combination of urban wastewater with kitchen food waste and its treatment w…
2017
[EN] The aim of this study was to evaluate the feasibility of treating the kitchen food waste (FW) jointly with urban wastewater (WW) in a wastewater treatment plant (WWTP) by anaerobic membrane technology (AnMBR). The experience was carried out in six different periods in an AnMBR pilot-plant for a total of 536 days, varying the SRT, HRT and the food waste penetration factor (PF) of food waste disposers. The results showed increased methane production of up to 190% at 70 days SRT, 24 hours HRT and 80% PF, compared with WW treatment only. FW COD and biodegradability were higher than in WW, so that the incorporation of FW into the treatment increases the organic load and the methane producti…
Data on physical and chemical characterization of wood combustion products derived at cogeneration power plants
2021
The data presented in this article are related to the research paper “Granulation of fly ash and biochar with organic lake sediments – A way to sustainable utilization of waste from bioenergy production” [1] in the context of waste material investigation and possible valorization instead of disposal. This article provides a comprehensive chemical and physical characterization of wood combustion products – fly ashes, bottom ashes, mixed ashes and biochar. Multiple analytical techniques and methodology were exploited to investigate the composition of wood combustion products, among them a loss on ignition, potentiometry, colorimetry, X-ray diffractometry, X-ray fluorescence spectrometry, indu…
L’Archivio S.A.C.S. del Museo Riso di Palermo. Valorizzazione dello Sportello per l’Arte Contemporanea della Sicilia
2021
L’archivio d’arte contemporanea è un dispositivo culturale attivo volto a selezionare, catalogare, divulgare, esporre e promuovere la creatività artistica in divenire. Queste pratiche di salvaguardia e valorizzazione dei beni artistici sono attività necessarie per la gestione e l’elaborazione del patrimonio culturale, come anche per l’interpretazione del presente. La ricerca sul S.A.C.S., lo Sportello per l’Arte Contemporanea della Sicilia del Museo Riso di Palermo, nasce per valorizzare, attraverso l’approccio integrato della museologia e della fenomenologia dell’arte contemporanea, un giovane Archivio d’arte dedicato ai nuovi creativi siciliani. La tesi, strutturata in tre capitoli, compr…
Bivalve mollusks shells valorisation and recycling: market potentiality and novel building products
2023
Construction is a fundamental driver of the world economy, recognized as a sector that generates a great contribution to the social and economic development. At the same time, it shows an enormous environmental impact through an unstoppable consumption of non-renewable resources, a high energy consumption, and an associated atmospheric emission of pollutant. Consequently, the research and development of novel and green production processes and sustainable building materials is of paramount importance. The sustainability of materials and production processes could be improved by enhancing and reusing wastes from various industrial sectors. In this paper, the fishery sector will be analysed, …
REVERSE ELECTRODIALYSIS FOR POWER PRODUCTION FROM OILFIELD WASTEWATERS
2022
Produced waters (PWs) are wastewaters generated by crude-oil extraction processes. They can present very different characteristics depending on the field location and production process. Dispersed oil, dissolved organics and solid particles are usually the main components. Moreover, PWs can contain a very high quantity of dissolved salts 1, with a total dissolved solid (TDS) concentration up to 300 g/L. Each barrel of extracted oil requires the simultaneous extraction of 3 barrels of produced water2 on average. PWs are often discharged into the sea, or sent in evaporation ponds thus leading to a dramatic environment impact3. Reinjection in the extraction well is currently the most common an…
TECNOLOGIE E STRATEGIE PER LA VALORIZZAZIONE DEI BENI CULTURALI E ARCHEOLOGICI - Technologies et stratégies pour la promotion du patrimoine culturel …
2014
I beni archeologici costituiscono un capitale di valore strutturato con propri elementi distintivi di identità e di autenticità. Valorizzare queste importanti risorse del territorio, significa potenziarne la conservazione e la tutela ed al contempo incrementarne la promozione e la fruizione responsabile. In questo processo di produzione di valore, il contributo della disciplina tecnologica si pone in modo propositivo e strategico: sia in termini di diffusione della conoscenza, potenziando l’interpretazione materiale ed immateriale del bene archeologico, attraverso l’uso di strumenti evoluti per l’analisi del reperto archeologico; sia nel miglioramento dell’utilizzazione pubblica del bene, n…
