We study the thermodynamics of mixtures of Jagla ramp potential (JRP) particles and hard spheres (HS), with HS mole fractions 0.10, 0.15, 0.20 and 0.50. The bulk JRP system exhibits both water-like anomalies and a liquid-liquid critical point (LLCP). In the mixtures, the presence of a LLCP is preserved up to the highest HS mole fraction. The results indicate that the temperature of occurrence of the LLCP increases in solutions of hydrophobic solutes in water.

Abstract
We study the thermodynamics of mixtures of Jagla ramp potential (JRP) particles and hard spheres (HS), with HS mole fractions 0.10, 0.15, 0.20 and 0.50. The bulk JRP system exhibits both water-like anomalies and a liquid-liquid critical point (LLCP). In the mixtures, the presence of a LLCP is preserved up to the highest HS mole fraction. The results indicate that the temperature of occurrence of the LLCP increases in solutions of hydrophobic solutes in water.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
