Research Highlights

  • Validation of the no-slip boundary condition for the solid-liquid interface.
  • Spectroscopic proof of nanobubble existence.
  • Development of enzymatic nanolithography method.
  • Understanding of the role of dynamic adsorption in colloidal stability.
  • Elucidation of the structure and forces occurring in surface aggregates of surfactant molecules.
  • Determination of correlations between forces acting on individual particles, and the rheology and consolidation of many-particle systems.
  • Development of method for measuring the forces on colloidal particles.
