Merging Features from Green's Functions and Time Dependent Density Functional Theory: A Route to the Description of Correlated Materials out of Equil…
2016
We propose a description of nonequilibrium systems via a simple protocol that combines exchange-correlation potentials from density functional theory with self-energies of many-body perturbation theory. The approach, aimed to avoid double counting of interactions, is tested against exact results in Hubbard-type systems, with respect to interaction strength, perturbation speed and inhomogeneity, and system dimensionality and size. In many regimes, we find significant improvement over adiabatic time dependent density functional theory or second Born nonequilibrium Green's function approximations. We briefly discuss the reasons for the residual discrepancies, and directions for future work.
Spunti critici sull’aggiornamento della normativa europea in tema di qualità dell’aria
2022
This paper aims at presenting an argument in favour of the need for a prompt update of the European legislation on air quality, by taking its cue from the current situation in Italy. The paper starts by providing a definition of outdoor air pollution and by referring to the most influential Italian scientific studies on the main health risks connected. The perspective then shifts to the analysis of the relevant legislation at both European and national level in an attempt to systematically recompose the complex framework of plans and regulations adopted for the containment and prevention of outdoor pollution. In this framework, the analysis of the three infringement procedures opened agains…
Runoff coefficients to predict peak discharge at hillslope scale: A small contribution to theoretical hydrology
2018
The science of hydrology holds a central role in the field of environmental Earth science, being intimately connected to meteorology, climatology, hydrogeology and ecology. In particular, the knowledge of hillslope hydrology is fundamental for understanding the flood phenomenon, for predicting the peak discharge and its probability distribution, which is necessary in many practical applications (design of hydraulic structures, urban, extra-urban planning, etc.). Using different approaches, there have been a multitude of studies on the hydrologic response at hillslope scale. One approach for deriving the hillslope response utilizes, in a distributed form, the differential equations of unstea…

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…

Proteins in Ionic Liquids: Reactions, Applications, and Futures
2019
Biopolymer processing and handling is greatly facilitated by the use of ionic liquids, given the increased solubility, and in some cases, structural stability imparted to these molecules. Focussing on proteins, we highlight here not just the key drivers behind protein-ionic liquid interactions that facilitate these functionalities, but address relevant current and potential applications of protein-ionic liquid interactions, including areas of future interest.
