ABSTRACT
The interface of both the surface and the bulk phase constitute the most active physicochemical state. It develops a highly active surface which is noted as viscous or viscosity surface of a thin film which is formed on the solid surface of the capillary. After a quantitative study of aqueous gelatin solutions the medium could be changed from an aqueous solution to aqueous ethanol, aqueous sorbitol, and aqueous polyethylene glycol. Gelatin of the photographic and pharmaceutical grade is obtained from beef bones and is dissolved in hot water and set to cool. Viscosity and friccohesity measurements become attractive research work with gelatin solutions with fluorescent dyes and dendrimers. Gelatin mixtures could be studied with several alkali salts, surfactants, dendrimers, and lanthanides. The level of homogenization of gelatin with several solvents in the presence of surfactants could constitute a nanoemulsion for industrial applications for developing a heat and electricity conducting membrane.
