Marangonin.

1948 J. J. Bikerman Surface Chem. i. 81 If, on a contaminated surface of water, some ignited talc is spread and the film of contamination + talc is removed by a scoop or blotting paper from a part of the surface, it is seen that the talc covered area rapidly invades that from which the film has been removed. The cleaner surface has a higher surface tension and reacts against the lower surface tension of the contaminated surface. This phenomenon may be called the Marangoni effect, as C. Marangoni..apparently was the first to explain movements in the surface by local variations of surface tension.

1988 Physical Rev. Lett. 60 964/2 It is possible that the Marangoni effect is inhibited because of the presence of an adsorbed film on the surface of the water.

1994 Nature 1 Dec. 414/2 There has recently been a revival of interest in ‘Marangoni effects’.

1959 C. V. Sternling & L. E. Scriven in Jrnl. Amer. Inst. Chem. Engin. 5 521/2 That the authors' simplified model is subject to Marangoni instability is now established.

1983 Jrnl. Colloid & Interface Sci. 93 392 The influence that various factors (dynamic interfacial tension, Marangoni instability, and natural convection) have to produce spontaneous pulsation of liquid drops in binary systems and [etc.].

1966 Physics of Fluids 9 615/1 That convection cells can be induced by surface tension variations in the presence of temperature or concentration gradients was first established by Pearson... Pearson showed that this mode of instability..is governed by the magnitude of a new dimensionless group B (often referred to as the Marangoni number).

1980 Sci. Amer. July 87/1 Bénard convection sets in when the Marangoni number exceeds a critical value.

1996 New Scientist 24 Feb. 85/2 For flows driven by surface tension the corresponding variable is the Marangoni number in which surface tension forces replace buoyancy forces.
