Rough ideas on wetting
After a brief presentation of the classical laws of wetting, we review di(erent phenomenological descriptions of rough wetting, i.e., show how these classical laws must be modi*ed on rough solids. This introduces the questions of hemi-wicking (can a *lm propagate inside the texture of a solid ?), rough *lms (is it possible for a liquid *lm to follow the roughness of a solid ?) and super-hydroph...
متن کاملThermal windows on the trunk of hauled-out seals: hot spots for thermoregulatory evaporation?
Seals have adapted to the high heat transfer coefficient in the aquatic environment by effective thermal insulation of the body core. While swimming and diving, excess metabolic heat is supposed to be dissipated mainly over the sparsely insulated body appendages, whereas the location of main heat sinks in hauled-out seals remains unclear. Here, we demonstrate thermal windows on the trunk of har...
متن کاملWetting of Rough Walls
Quenched geometric disorder of a wall delimiting a spectator phase can have dramatic effects on the nature of critical wetting transitions. We consider selfaffine walls in 2D with roughness exponent £w. Transfer matrix results for directed interfacial models with short-range interactions suggest that wetting turns firstorder as soon as L,W exceeds £0, the anisotropy index of interface fluctuati...
متن کاملeffect of oral presentation on development of l2 learners grammar
this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
15 صفحه اولTriple-point wetting on rough substrates.
The influence of substrate roughness on the wetting scenario of adsorbed van der Waals films is investigated by theory and experiment. Calculating the bending free energy penalty of a solid sheet picking up the substrate roughness, we show that a finite roughness always leads to triple-point wetting reducing the widths of the adsorbed solid films considerably as compared to that of smooth subst...
