Photochemical sample treatment: A greener approach for PCBs analysis in sediments
2012
Electrical installations and industrial outlets are the major source in environment of chlorinated organic compounds. These are distributed in several geographical areas through long-range atmospheric transport and deposition. Additionally, chlorinated organic compounds can be introduced in the food chain and reach the consumers in very high levels. Besides toxicological studies on PCBs, recent research is focusing on more sophisticated analytical methods for PCBs detection. Distribution and dispersion of PCBs mostly occur through air, water, soils, and sediments. The latter are complex matrices whose analysis often involves costly extraction and purification procedures. In particular, PCBs…

Social Green Planning e Urban Planning ovvero della produzione giocosa di una tragedia di successo in quattro movimenti
2016
Il contributo riguarda la postfazione dell'intero volume. Nel contributo vengono rintracciate quattro chiavi di lettura: 1) non può esistere una pianificazione territoriale contemporanea se non è integrata; 2) la resilienza dell'ecologia nella pianificazione risiede nella capacità di cogliere i valori profondi che muovono la cittadinanza verso la autentica partecipazione; 3) Drammaturgia e Neuroscienze sono i due argomenti sullo sfondo del volume curato dai due autori: sono immanenti, sono le condizioni esterne che regolano, in caso di malfunzionamento o di proteste il piano/progetto di paesaggio confinando o limitando i protagonismi eventuali dei giocatori coinvolti; 4) il SGP è una strate…

Normatywne kształtowanie terenów zieleni w mieście podstawą budowania zrównoważonych miast
2021
Tereny zieleni w mieście są istotnym zagadnieniem w kształtowaniu struktury funkcjonalno-przestrzennej miasta, a także kształtowania jego rozwoju w sposób zrównoważony. W literaturze przedmiotu zwraca się uwagę na konieczność dążenia do równowagi między celami społecznymi, ekologicznymi i ekonomicznymi, które powinny być definiowane w polityce rozwoju jednostek terytorialnych różnych szczebli, w tym także miast. Istotne jest również zachowanie równości międzypokoleniowej m.in. poprzez zachowanie zasobów środowiska (Fiedor, 2002,s. 23). J. Słodczyk zwraca uwagę, że w realizacji koncepcji miasta zrównoważonego istotne są takie zagadnienia jak m.in. forma przestrzenna miasta, proekologiczne ro…
Preparation of tungstophosphoric acid/cerium-doped NH2-UiO-66 Z-scheme photocatalyst: a new candidate for green photo-oxidation of dibenzothiophene a…
2021
International audience; The goal of this study was to introduce an effective visible-light induced photocatalytic system with a good ability for photocatalytic oxidative desulfurization (PODS) and denitrogenation (PODN) using molecular oxygen (O2) as an oxidant. In this regard, tungestophosphoric acid (PW12) was supported onto cerium-doped NH2-UiO-66 (PW12/Ce-NUiO-66) and employed for the photo-oxidation of dibenzothiophene (DBT) and quinoline (Qu). Herein, using cerium (Ce) as a “mediator” facilitated the separation of charge carriers, while NH2-UiO-66 remarkably enhanced the surface area with plentiful adsorption sites and shifted the adsorption edge of PW12to the visible region. The sum …
How different policy instruments affect green product innovation : A differentiated perspective
2018
Based on representative firm-level data for the three countries Austria, Germany, and Switzerland, we investigate the effects of energy-related regulations, taxes, voluntary agreements, and subsidies on the creation of green energy products, and analyze through which channels policy affects green product innovation and which factors mediate the observed effects. Policy may affect green product innovation by directly stimulating the supply of green products/services, or more indirectly by stimulating the demand for green products/services. Our data set allows us to distinguish between the two channels, which improves our understanding of the frequently observed positive net effect of policie…
Economic Sustainability of Italian Greenhouse Cherry Tomato
2014
Greenhouse tomato cultivation plays an important role in Sicily, being the primary production area in Italy, due to its favorable pedo-climatic conditions that permit extra-seasonal productions. In Sicily, more than half of greenhouse tomato production is derived from the Province of Ragusa on the southeastern coast, where especially cherry tomato typologies are cultivated. Over the last decade, the Ragusa Province has registered a decrease both in terms of greenhouse tomato area and harvested production due to several structural problems that would require restructuring of the tomato supply chain. Thus, since recognition of real costs and profitability of tomato growing is a vital issue, b…
