• How Slippery are SLIPS? Measuring Effective Slip on Lubricated Surfaces with Colloidal Probe Atmoc Force Microscopy 

      Scarratt, Liam R.J.; Zhu, Liwen; Neto, Chiara
      Published 2019
      Lubricant-infused surfaces have attracted great attention recently and are described as slippery (SLIPS). Here we measured hydrodynamic drainage forces on SLIPS by colloid probe atomic force microscopy (AFM) and quantified ...

    • Large Effective Slip on Lubricated Surfaces Measured with Colloidal Probe AFM 

      Scarratt, Liam R.J.; Zhu, Liwen; Neto, Chiara
      Published 2020
      In this work, we study the interfacial boundary conditions at the interface between two immiscible liquids under laminar flow. We measure the hydrodynamic drainage forces acting on a colloid probe as it approaches a flat ...

    • Reliable measurement of slip using colloid probe atomic force microscopy 

      Zhu, Liwen
      Published 2012-08-01
      Recent research has shown that Newtonian liquids can slip at solid surfaces in confined geometries, which contradicts the classical no-slip boundary condition in which the liquid is stationary at the solid surface. The ...
