    Semi-empirical models of galaxy formation and evolution

    No full text
    We provide a review on semi-empirical models of galaxy formation and evolution. We present a brief census of the three main modeling approaches to galaxy evolution, namely hydrodynamical simulations, semi-analytic models, and semi-empirical models (SEMs). We focus on SEMs in their different flavors, i.e. interpretative, descriptive and hybrid, discussing the peculiarities and highlighting virtues and shortcomings for each of these variants. We dissect a simple and recent hybrid SEM from our team to highlight some technical aspects. We offer some outlook on the prospective developments of SEMs. Finally, we provide a short summary of this review

    Libertà religiosa ed economie alternative. Spunti di ricerca

    No full text
    Il saggio ha lo scopo di presentare alcune prime linee di ricerca sulle forme di gestione del denaro alternative a quelle ufficiali, diffuse in particolare nelle comunità degli immigrati come il micro-credito o le associazioni di credito rotativo. Si tratta di sistemi di gestione del denaro che molto spesso sono strettamente collegati alle esperienze religiose o comunque al sistema di credenza cui appartengono coloro che se ne servono

    Ce3+and La3+ions in ethylammonium nitrate: A XANES and molecular dynamics investigation

    No full text
    Diluted solutions of Ce(NO3)3and La(NO3)3in ethylammonium nitrate (EAN) were investigated using molecular dynamics (MD) simulations and X-ray absorption near edge structure (XANES) spectroscopy. New La-O and Ce-O Lennard-Jones parameters were optimized to provide an accurate atomistic description of the nitrato complexes at low computational cost. XANES spectra analysis, along with radial and combined distance-angle distributions from MD simulations, indicate that the main metal species in solution is an icosahedral nitrato complex with a 12-fold cation-oxygen coordination and an equilibrium between monodentate and bidentate ligands

    Influence of Counterions on the Hydration Structure of Lanthanide Ions in Dilute Aqueous Solutions

    No full text
    A synergic approach combining molecular dynamics (MD) simulations and X-ray absorption spectroscopy (XAS) has been used to investigate diluted (0.1 M) aqueous solutions of two lanthanide ions (Ln3+), namely, La3+ and Dy3+, with triflate, nitrate, and bis­(trifluoromethylsulfonyl)­imide (Tf2N–) as counterions. The different complexing ability of the three anions has been highlighted by the analysis of the MD simulations: Tf2N– does not form inner-sphere complexes, while a small amount of triflate coordinates both the La3+ and Dy3+ cations in their first solvation shell. On the other hand, the nitrate ion is almost absent in the La3+ first coordination sphere, while forming contact ion pairs with Dy3+. Both lanthanide ions are found to preferentially interact with the water molecules, and the total number of oxygen atoms coordinating the Ln3+ cations in their first solvation sphere is the same in all of the solutions, regardless of whether they belong to water molecules or to the counterion. The presence of counterions in the cation first or second shell changes neither the first shell distance nor the symmetry of the hydration complex formed in solution. The MD results have been confirmed by comparison with the Ln K-edge XAS experimental data, and the quantitative analysis of the extended X-ray absorption fine structure (EXAFS) spectra of the three salt solutions has provided a definite proof of the accuracy of the force field employed in the simulations and of the MD structural result. The anion–water and water–water hydrogen bond lifetimes have been analyzed highlighting the slow down effect of the triflate, nitrate, and Tf2N– anions on the hydrogen bond dynamics in the Ln3+ first solvation shell, with the effect being stronger in the Dy3+ solutions, due to the higher charge density of the Dy3+ ion as compared to La3+
