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…
