The Charge Transfer Problem in Density Functional Theory Calculations of Aqueously Solvated Molecules

Ivano Tavernelli, Basile Curchod

Recent advances in algorithms and computational hardware have enabled the calculation of excited states with time-dependent density functional theory (TDDFT) for large systems of O(1000) atoms. Unfortunately, the aqueous charge transfer problem in TDDFT (w ...

Energy Consumption Versus Antioxidant Activity of Pressurized Fluid Extracts from Pfaffia glomerata Roots

François Maréchal, Adriano Viana Ensinas, Juliana Queiroz Albarelli, Diego Tresinari dos Santos

Conventional extraction techniques have been applied to obtain antioxidant extracts from Pfaffia glomerata roots, most of the times, using polar extracting solvents. Even if these techniques are able to provide extracts with antioxidant activities, more en ...

Liquid film circumferential asymmetry prediction in horizontal annular two-phase flow

John Richard Thome, Andrea Cioncolini

This study considers the prediction of the degree of asymmetry in the circumferential distribution of the liquid film in the tube cross section of horizontal annular gas-liquid two-phase flow, endemic of the lower region of this flow regime near the strati ...

Geometry as a Catalyst: How Vapor Cavities Nucleate from Defects

Simone Meloni

The onset of cavitation is strongly enhanced by the presence of rough surfaces or impurities in the liquid. Despite decades of research, the way the geometry of these defects promote the nucleation of bubbles and its effect on the kinetics of the process r ...
