WebApr 10, 2024 · Finally, it is worth to mention that, to our best knowledge, there are no scientific reports relating the Marangoni effect to the propulsion of individual cells in the natural world. In spite of that, it is known that some of the arthropods that are known to “walk on the water” are also able to “surf” the water by exploiting the ... WebJun 25, 2024 · Marangoni flows arising from thermal or solute-driven gradients in surface tension can also generate recirculating flows. Researchers have described flow in evaporating droplets mainly in the...

WebAug 5, 2024 · This directional cell migration is described by the Marangoni flux. The Marangoni flux could represent a main factor responsible for cell sorting. The … The Marangoni effect (also called the Gibbs–Marangoni effect) is the mass transfer along an interface between two phases due to a gradient of the surface tension. In the case of temperature dependence, this phenomenon may be called thermo-capillary convection (or Bénard–Marangoni convection). See more This phenomenon was first identified in the so-called "tears of wine" by physicist James Thomson (Lord Kelvin's brother) in 1855. The general effect is named after Italian physicist Carlo Marangoni, who studied it for his … See more Since a liquid with a high surface tension pulls more strongly on the surrounding liquid than one with a low surface tension, the presence of a … See more Under earth conditions, the effect of gravity causing natural convection in a system with a temperature gradient along a fluid/fluid … See more • Plateau–Rayleigh instability — an instability in a stream of liquid • Diffusioosmosis - the Marangoni effect is flow at a fluid/fluid … See more As an example, wine may exhibit a visible effect called "tears of wine". The effect is a consequence of the fact that alcohol has a lower surface tension and higher volatility than water. The water/alcohol solution rises up the surface of the glass lowering the See more A familiar example is in soap films: the Marangoni effect stabilizes soap films.
