Oggetto del presente lavoro è la presentazione del modello di agrivoltaico sviluppato da EF Solare Italia, Le Greenhouse e SET Energie, che integra agricoltura e produzione di energia rinnovabile attraverso strutture elevate e sistemi ad inseguimento solare. Il sito sperimentale di Scalea (CS) rappresenta una best practice per lo sviluppo di sistemi agrivoltaici, oggetto di studio nell’ambito del progetto di ricerca “Fotovoltaico ad alta Efficienza” del piano triennale di realizzazione 2022-2024 della Ricerca di Sistema Elettrico nazionale – Accordo di Programma MASE-ENEA. Il confronto tra prototipi con tracker e struttura fissa, rispetto a quelli in campo aperto, mostrano risultati agronomici promettenti: le piante sotto i pannelli presentano una superficie fogliare più estesa, stomi più grandi e un potenziale idrico superiore, con efficienza fotosintetica simile al pieno campo. Inoltre, si evidenzia come l’ombreggiamento parziale riduca lo stress da iper-irraggiamento e il fabbisogno idrico, grazie anche a sistemi di sub-irrigazione. Lo studio presenta dati inediti su monitoraggio e sviluppo delle colture comparato tra fisso e tracker. Inoltre, evidenzia i benefici ambientali ed agronomici dell’agrivoltaico. Questo sistema integrato si conferma soluzione strategica per la transizione energetica, grazie ad un approccio di sviluppo condiviso e che valorizza il territorio e le comunità locali.

Clearly defined principles are essential elements of GHG accounting and reporting guidelines, protocols, and standards to address the unavoidable expert judgments that must be applied to address ambiguities in these documents. The IPCC guidelines identify transparency, accuracy, completeness, (time series) consistency, and comparability as its foundational data quality principles. The principles of conservativeness, relevance, and comparability see varied use across major GHG accounting references. These differences in principles, especially with respect to the principle of comparability, indicate there are underlying problems with many GHG accounting protocols and standards now heavily referenced and applied.

Abstract The requirements of NFPA 652 Standard regarding Dust Hazard Analysis on the Fundamentals of Combustible Dust had to be fully implemented in 2020. In this article, we present the results of a survey that tested how well those with responsibility for NFPA 652 compliance have understood its requirements. We find that although there is a good level of understanding about what is required there are never‐the‐less a number of areas where the standard has been misunderstood.

Correction for ‘Hollow Al2O3 spheres prepared by a simple and tunable hydrothermal method’ by Guangxin Xue et al., RSC Adv., 2015, 5, 13385–13391.

Doped perovskites possess better structure properties, the catalytic performance depends on the behaviour of the reactants.

Average publication times have decreased from 5.2 to 4.3 months, but the impact factor has remained at around 2. Reflecting the current surge in methods development, Acta D has published many important methodological papers in the past 3 years, both in regular issues and in the special issues dedicated to the standout CCP4 study weekend series. The number of structural papers has remained steady at about 10 per issue, but the number of crystallization papers has increased to the point where they constitute 60% of papers in the journal. From 2005, however, these will be published in the allelectronic sister journal Acta F. Acta D will then focus on crystallographic methods and new protein structures, aiming to attract more high profile structural papers, and will seek to increase the number of topical reviews and commentaries.
