How Slippery are SLIPS? Measuring Effective Slip on Lubricated Surfaces with Colloidal Probe Atmoc Force Microscopy
Scarratt, Liam R.J.; Zhu, Liwen; Neto, ChiaraPublished 2019Lubricant-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 ...Open AccessArticle -
Large Effective Slip on Lubricated Surfaces Measured with Colloidal Probe AFM
Scarratt, Liam R.J.; Zhu, Liwen; Neto, ChiaraPublished 2020In 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 ...Open AccessArticle -
Mechanical properties of Ropaque hollow nanoparticles
Zhu, Liwen; Nguyen, Duc; Davey, Tim; Baker, Matthew; Such, Chris; Hawkett, Brian; Neto, ChiaraPublished 2017-10-15The elastic properties and strength upon compression of commercial Ropaque polystyrene hollow particles were investigated by atomic force microscopy (AFM). These particles are commonly used in paints as opacifying agents, ...Open AccessArticle -

Reliable measurement of slip using colloid probe atomic force microscopy
Zhu, LiwenPublished 2012-08-01Recent 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 ...Open AccessThesis -
Soft-Hard Janus Nanoparticles for Polymer Encapsulation of Solid Particulate
Nguyen, Duc; Zhu, Liwen; Huynh, Vien T.; Azniwati, Abd-Aziz; Pham, Nguyen T. H.; Lam, Minh T.; Serelis, Algirdas K.; Davey, Tim; Such, Chris; Neto, Chiara; Hawkett, Brian S.Published 2020We demonstrate a scalable continuous feed method for the synthesis of polymer Janus nanoparticles with different composition and with different aspect ratios between lobes, including with one hard cross-linked polystyrene ...Open AccessArticle
