Wetting microscopic theory

This paper is not the proper forum for comprehensive aluminum data, but in developing any theory of glitter the theory must account for most observed phenomena. The phenomena of the wet reacted aluminum has been handled in part. Additionally it is observed that such aluminum does not react as quickly with a drop of water or sodium hydroxide solution after it is removed from the spritzel reactions. Dye absorption techniques confirm this microscopically. Can the theory of oxidizer accumulation in the spritzel reactions account for this damaged aluminum performance Asymmetrical spritz with flitter-like residues would be expected, diminished brilliance of the spritz and greatly increased delay would be expected, and a failure to fire in a spritz-like flash would be expected in the extreme case. All of these are observed. Aluminums of high surface-to-mass ratio would be expected to fire as spritz in the spritzels at relatively low sulfate concentrations unless other factors override this condition, such as viscosity and mobility of fluid transport in the spritzel. This is... [Pg.43]

How can we reconcile this with om microscopic picture of the wetting layer derived from the square gradient theory To do this we must go back to... [Pg.229]

In this case the comparison between experiment and theory is more straightforward, and any deviation from the macroscopic wetting behavior due to microscopic effects can be readily discerned through the analysis of the droplet profile. Among the most studied substrates are freshly cleaved mica and chemically passivated silicon. The surface of freshly cleaved mica is atomically... [Pg.242]
