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 has been predicted that a charged particle, moving parallel to a charged wall in an electrolyte, should experience a lift force that, contrarily to electr…
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 Elastohydrodynamic Lift Force at the Nanoscale
Zaicheng Zhang, Vincent Bertin, Muhammad Arshad +3
We present the first direct measurement of the elastohydrodynamic lift force acting on a sphere moving within a viscous liquid, near and along a soft substrate under nanometric con…
Visco-elastic drag forces and crossover from no-slip to slip boundary conditions for flow near air-water interfaces
Abdelhamid Maali, Rodolphe Boisgard, Hamza Chraibi +3
The "free" water surface is generally prone to contamination with surface impurities be they surfactants, particles or other surface active agents. The presence of such impurities…
