Non-Stokes Drag Coefficient in Single-Particle Electrophoresis: New Insights on a Classical Problem
Maijia Liao, Ming-Tzo Wei, Shixin Xu +2
We measured the intrinsic drag coefficient of a single charged particle by optically trapping the particle and applying an alternating electric field, and found it to be markedly d…
The Poisson Boltzmann equation and the charge separation phenomenon at the silica-water interface: A holistic approach
Maijia Liao, Li Wan, Shixin Xu +2
The Poisson Boltzmann equation is known for its success in describing the Debye layer that arises from the charge separation phenomenon at the silica/water interface. However, by t…
A variational approach to the moving contact line hydrodynamics
Tiezheng Qian, Xiao-Ping Wang, Ping Sheng
In immiscible two-phase flows, contact line denotes the intersection of the fluid-fluid interface with the solid wall. When one fluid displaces the other, the contact line moves al…
Molecular hydrodynamics of the moving contact line in two-phase immiscible flows
Tiezheng Qian, Xiao-Ping Wang, Ping Sheng
The ``no-slip'' boundary condition, i.e., zero fluid velocity relative to the solid at the fluid-solid interface, has been very successful in describing many macroscopic flows. A p…
Liquid crystal pretilt control by inhomogeneous surfaces
Jones T. K. Wan, Ophelia K. C. Tsui, Hoi-Sing Kwok +1
We consider the pretilt alignment of nematic liquid crystal (LC) on inhomogeneous surface patterns comprising patches of homeotropic or homogeneous alignment domains, with azimutha…
Hydrodynamic slip boundary condition at chemically patterned surfaces: A continuum deduction from molecular dynamics
Tiezheng Qian, Xiao-Ping Wang, Ping Sheng
We investigate the slip boundary condition for single-phase flow past a chemically patterned surface. Molecular dynamics (MD) simulations show that modulation of fluid-solid intera…
