Outline of Final Research Achievements

1)We constructed a theory of dielectric response in liquid water using large-scale molecular dynamics simulation. We also examined nonequilibrium relaxation
after electric field reversal. 2) We presented a theory of nanobubbles when a small amount of oxygen is added to ambient water. We accounted for solvation of oxygen in water. 3) We predected that colloidal particles aggregate due to local phase separation (bridging) in near-critical binary mixture. 4) We showed various new effects when hydrophilic and hydrophobic ions (antagonistic salt) are added to water-oil mixtures.
