Journal ArticleDOI
Rate-dependent slip of Newtonian liquid at smooth surfaces.
Yingxi Zhu,Steve Granick +1 more
TL;DR: With increasing flow rate and partially wetted surfaces, hydrodynamic forces became up to 2-4 orders of magnitude less than expected by assuming the no-slip boundary condition that is commonly stated in textbooks.
Journal ArticleDOI
Limits of the Hydrodynamic No-Slip Boundary Condition
Yingxi Zhu,Steve Granick +1 more
TL;DR: The critical shear stress and shear rate to observe deviations from predictions using the no-slip boundary condition increased nearly exponentially with increasing roughness and diverged at approximately 6 nm rms roughness.
Journal ArticleDOI
Slippery questions about complex fluids flowing past solids.
TL;DR: Attention is drawn to unresolved topics of investigation and to the potential to capitalize on 'slip at the wall' for purposes of materials engineering.
Journal ArticleDOI
Viscosity of interfacial water.
Yingxi Zhu,Steve Granick +1 more
TL;DR: The effective shear viscosity and frequency-dependent dynamic oscillatory shear spectra of water containing monovalent or divalent ions, confined between mica crystals at 1-2 water molecules thickness, oscillated with twist angle with the period expected for the pseudohexagonal surface lattice.
Journal ArticleDOI
Hydrophobicity at a Janus Interface
TL;DR: Water confined between adjoining hydrophobic and hydrophilic surfaces (a Janus interface) is found to form stable films of nanometer thickness whose responses to shear deformations are extraordinarily noisy, indicating a distribution of relaxation processes rather than any dominant one.
