Relation between occupation in the first coordination shells and Widom line in Core-Softened Potentials
Evy Salcedo, Ney Barraz, Marcia Barbosa
Three core-softened families of potentials are checked for the presence of density and diffusion anomalies. These potentials exhibit a repulsive core with a softening region and at…
Anomalies in a waterlike model confined between plates
Leandro Batirolla Krott, Marcia Cristina Bernardes Barbosa
Using molecular dynamic simulations we study a waterlike model confined between two fixed hydrophobic plates. The system is tested for density, diffusion and structural anomalous b…
Hydration and anomalous solubility of the Bell-Lavis model as solvent
Marcia M. Szortyka, Carlos E. Fiore, Marcia C. Barbosa +1
We address the investigation of the solvation properties of the minimal orientational model for water, originally proposed by Bell and Lavis. The model presents two liquid phases s…
Connection Between Minimum of Solubility and Temperature of Maximum Density in an Associating Lattice Gas Model
Marcia M. Szortyka, Maurício Girardi, Vera B. Henriques +1
In this paper we investigate the solubility of a hard - sphere gas in a solvent modeled as an associating lattice gas (ALG). The solution phase diagram for solute at 5% is compared…
Diffusion Enhancement in Core-softened fluid confined in nanotubes
José R. Bordin, Alan B. de Oliveira, Alexandre Diehl +1
We study the effect of confinement in the dynamical behavior of a core-softened fluid. The fluid is modeled as a two length scales potential. This potential in the bulk reproduces…
