Criminalità e violenza in Sardegna: una interpretazione
No full textAll’inizio degli anni ’40 del secolo XIX, nell’ambito di una mirabile sintesi di
storia sarda, Carlo Cattaneo descrive la Sardegna di fine ‘700 come terra isolata e
sempre più desolata, a causa della “recrudescenza dell’anarchia feudale e della
pastorale licenza”. A tale situazione connette un clima di violenza talmente diffuso
che “sopra una popolazione di 360.000 abitanti incirca si contano sino a mille
omicidj in un anno”
Capturing Volatile Organic Compounds Employing Superalkali Species
No full textIn this study, the interactions between the superalkali species Li3F2 and four volatile organic compounds (VOCs), methanol, ethanol, formaldehyde, and acetaldehyde, are assessed using the CBS-QB3 composite model. Adiabatic ionization energy (AIE), adiabatic electron affinity (AEA), binding energy (BE), charge transfer (~q), and highest occupied molecular orbital and lowest unoccupied molecular orbital (HOMO-LUMO) gaps have been computed. Stronger interactions are observed between Li3F2 and the aldehydes than alcohols. The smaller aldehydes show a larger BE with Li3F2 than the bigger aldehydes. However, alcohol clusters do not show this trend due to their weak interactions (low BEs). Both alcohol clusters increase their binding energies as they become cations. This
unexpected behavior is explained based on molecular orbital arguments
