The lab-on-a-chip concept is a strong driving force for studying liquid motion at small scales. The Department is engaged
in exploring the limits of miniaturizability of such chips due to thermal fluctuations and to study their performance. In
this context at the nanoscale bulk hydrodynamic equations become invalid and phenomena which are irrelevant on the micronscale
or larger, or which can be summarily incorporated in terms of boundary conditions, become important.
Among these features are long-ranged molecular interactions, such as dispersion forces, thermal fluctuations, hydrodynamic
slip, segregation of mixtures and solutions at walls, and electrical double layers. By using continuum interface dynamics,
stochastic thin film equations, mesoscopic hydrodynamics, time-dependent density functional theory, kinetic Monte Carlo simulations,
Brownian dynamics, and molecular dynamics simulations, significant progress has been achieved.
