The Marangoni Effects

Nanorings and rods interconnected by self-assembly mimicking an artificial network of neurons

“…In this sense, the strong self-assembly tendency of 4a to form interconnected networks from cast solutions has mediated the system to the entropically favoured formation of extended collinear networks of interconnected carbon nanotubes over larger areas and volumes. This spatially aligned higher-level superstructure is facilitated by the considerable shape anisotropy of the nanotubes and the rods/rings in the molecular network, thus resulting in entropy-driven directional ordering 43,48 . Although this is not the first case of circularly arranged nanostructures (for example, nanoparticles 41,[49][50][51] , nanorods, 52 , nanowires 53 , carbon nanotubes 54,55 ), it represents to our knowledge the first example where self-assembled structures can efficiently address the orientation and interconnection of carbon nanotubes, both in circular structures and in long-range networks, and in a solid polymer matrix.…”

“…It is important to mention here that the spontaneous formation of rings by self-assembly has been scarcely reported. Most of the reported structures follow formation mechanisms derived from de-wetting processes in which either the spontaneous formation of pinholes, 2D bubbles, the concentric accumulation of material mediated by local capillarity (coffee-stain effect) or Marangoni-flow engineering produce rings on flat surfaces [38][39][40][41][42][43][44] . However, none of the latter mechanisms can explain the formation of the rings for derivatives 4 that are interconnected in a neural network fashion both on flat surfaces and inside a polymeric matrix.…”

A unified computational framework for bulk and surface elasticity theory: a curvilinear-coordinate-based finite element methodology

“…Earlier related contributions include those by Scriven (1960) on the dynamics of fluid interfaces. Scriven employed many of the fundamental concepts formalised by Gurtin and Murdoch (1975), including the use of the term surface elasticity (Scriven and Sternling, 1960). The study of the behaviour of fluid surfaces dates back to the work, primarily on the capillary effect, of Laplace, Young and Gibbs.…”

Design of a UV-responsive microactuator on a smart device for light-induced ON-OFF-ON motion

“…26,27 The driving force is induced by mass transfer along an interface between two types of liquids owing to a surface tension gradient caused by different compositions or temperatures. 28 Inspired by this phenomenon, scientists have applied the Marangoni effect as self-propelling power for the locomotion of macroscopic objects on interfaces. Yoshikawa and his co-workers 29 investigated the spontaneous motion of a solidliquid composite induced by the chemical Marangoni effect when an oil droplet attached to solid soap is placed on water.…”
