Polymeric Solvents Control Swelling-Induced Surface Creasing
Zechao Jiang, Zhaoyu Ding, Shaohua Yang +7
Surface creasing in swelling polymer gels is commonly attributed to compressive strain or interlayer mismatch, yet its general control remains unclear. Here we show that solvent po…
Quantitative measurements of the lift force acting on a sphere sliding along a liquid-liquid interface
Hao Zhang, Zaicheng Zhang, Abdelhamid Maali
This work explores the lift force experienced by a particle moving in a viscous fluid near a liquid-liquid interface. The lift force is induced by the interaction between the visco…
Nanoscale Electroviscous Lift Force
Hao Zhang, Zaicheng Zhang, Thomas Guérin +1
About forty years ago, it was predicted that a charged particle, moving parallel to a charged wall in an electrolyte, should experience a lift force that, contrarily to electrostat…
Contactless measurements of the elastic modulus of living cells using thermal fluctuations of atomic force microscope cantilever
Hao Zhang, Zaicheng Zhang, Etienne Harte +2
We present a contactless method for measuring the elastic modulus of living cells (human triple-negative breast cancer, MDA-MB-231) from the thermal fluctuations of an atomic force…
Direct measurement of the viscocapillary lift force near a liquid interface
Hao Zhang, Zaicheng Zhang, Aditya Jha +5
Lift force of viscous origin is widespread across disciplines, from mechanics to biology. Here, we present the first direct measurement of the lift force acting on a particle movin…
Unsteady drag force on an immersed sphere oscillating near a wall
Zaicheng Zhang, Vincent Bertin, Martin Essink +6
The unsteady hydrodynamic drag exerted on an oscillating sphere near a planar wall is addressed experimentally, theoretically, and numerically. The experiments are performed by usi…
