In this work we combine molecular dynamics simulations with the quasi-Gaussian entropy (QGE) theory to model the statistical mechanics and thermodynamics of ionic solutions. Results showed that the use of the gamma state model provides an excellent theoretical description of the solution behavior over a wide range of temperature. Such an approach makes possible, at relatively low computational costs, the evaluation of partial molar properties such as free energy and entropy which require a heavy computational effort to be estimated with the usual procedures.

Abstract
In this work we combine molecular dynamics simulations with the quasi-Gaussian entropy (QGE) theory to model the statistical mechanics and thermodynamics of ionic solutions. Results showed that the use of the gamma state model provides an excellent theoretical description of the solution behavior over a wide range of temperature. Such an approach makes possible, at relatively low computational costs, the evaluation of partial molar properties such as free energy and entropy which require a heavy computational effort to be estimated with the usual procedures.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
