Surface Tension of Liquid Iron-Nickel-Chromium Alloy System

Density and Temperature Dependencies of Liquid Surface Tension

In this paper the density and temperature dependencies of surface tension are investigated. Using the Lennard-Jones (12,6), as an effective pair interaction potential, a linear expression is derived for isotherms of g /r2  versus r2 for some normal and ChloroFluoroCarbons (CFCs)</...

Surface crystallization in a liquid AuSi alloy.

X-ray measurements reveal a crystalline monolayer at the surface of the eutectic liquid Au82Si18, at temperatures above the alloy's melting point. Surface-induced atomic layering, the hallmark of liquid metals, is also found below the crystalline monolayer. The layering depth, however, is threefold greater than that of all liquid metals studied to date. The crystallinity of the surface monolaye...

Surface magnetism in iron, cobalt, and nickel.

Surface tension helps a tongue grab liquid.

C apitalizing on the opportunities presented by the surface tension of aqueous liquids against air shows natural selection at its most creative. The paper in PNAS by Rico-Guevara and Rubega (1) describes how protruded hummingbird tongues curl lengthwise into a pair of tubes containing nectar. As a tongue contacts nectar on its lower surface or is withdrawn from full submersion, the surface tens...

Surface Tension Prediction for Liquid Mixtures

Recently Escobedo and Mansoori (AIChE J. 42(5): 1425, 1996) proposed a new expression, originally derived from statistical mechanics, for the surface tension prediction of pure fluids. In this report, the same theory is extended to the case of mixtures of organic liquids with the following expression, σm = [(1-Tr,m) Tr,m exp (0.30066/Tr,m + 0.86442 Tr,m) (P 0,m ρL,m P 0,m ρv,m)] 4 P0,m = { ΣiΣj...
