Query: Effect of interfaces on the nearby Brownian motion   Near-boundary Brownian motion is a classic hydrodynamic problem of great
importance in a variety of fields, from biophysics to micro-/nanofluidics.
However, due to challenges in experimental measurements of near-boundary
dynamics, the effect of interfaces on Brownian motion has remained elusive.
Here, we report a computational study of this effect using microsecond-long
large-scale molecular dynamics simulations and our newly developed Green-Kubo
relation for friction at the liquid-solid interface. Our computer experiment
unambiguously reveals that the t^(-3/2) long-time decay of the velocity
autocorrelation function of a Brownian particle in bulk liquid is replaced by a
t^(-5/2) decay near a boundary. We discover a general breakdown of traditional
no-slip boundary condition at short time scales and we show that this breakdown
has a profound impact on the near-boundary Brownian motion. Our results
demonstrate the potential of Brownian-particle based micro-/nano-sonar to probe
the local wettability of liquid-solid interfaces.
