Atomic force microscopy: force measurements and analysis, Brownian fluctuation spectroscopy, and imaging of nanostructures and related forces.
Interfacial nanorheolgy: interfacial viscosities, elasticity and diffusion of adsorbed surfactants, polymers, biomolecules and food colloids.
Bubble-particle and drop-drop interactions: surface forces and microhydrodynamics.
Liquid films, line tension, colloid and mineral surface chemistry, and heterocoagulation.
Foams, froths, emulsions, froth flotation separation, and water treatment.
Computation fluid dynamics (CFD) modeling and prediction of multiphase flows with mass and heat transfer: confined jets, jet wiping, turbulence energy dissipation in large mixing tanks, and particle-wall interactions in Eulerian-Eulerian models for multiphase particle flows.
