Ion-specific interactions between two colloidal particles are calculated using a modified Poisson-Boltzmann (PB)equationandMonteCarlo(MC)simulations. PBequationspresentgoodresultsofionicconcentration profiles around a macroion, especially for salt solutions containing monovalent ions. These equations include not only electrostatic interactions, but also dispersion potentials originated from polarizabilities of ions and proteins. This enables us to predict ion-specific properties of colloidal systems. We compared results obtained from the modified PB equation with those from MC simulations and integral equations. Phase diagrams and osmotic second virial coefficients are also presented for different salt solutions at different pH and ionic strengths, in agreement with the experimental results observed Hofmeister effects. In order to include the water structure and hydration effect, we have used an effective interaction obtained from molecular dynamics of each ion and a hydrophobic surface combined with PB equation. The method has been proved to be efficient and suitable for describing phenomena where the water structure close to the interface plays an essential role. Important thermodynamic properties related to protein aggregation, essential in biotechnology and pharmaceutical industries, can be obtained from the method shown here.

A complete nuclear matter calculation in lowest order Brueckner theory is done for a super soft core nucleon–nucleon potential due to de Tourreil, Rouben, and Sprung and the effect of including isobar degrees of freedom on binding energy, saturation, and half-shell G-matrices is considered in the frame work of the coupled channel formalism. The singlet and triplet S-state effective interaction is derived and its density and momentum dependence is studied. Comparison is made with the results obtained from the Reid soft core potential.
