Abstract

The Gibbs surface excess was examined by using surface tension vs. concentration curve and a new concept for the surface excess is presented based upon data from the evaporation rate of water, the activation energy of evaporation, and the BAM images for surfactant solution. As the result, the surface excess was found to concentrate not at the air/water interface but at some depth apart below the interface as bi-lamellar aggregates.

Abstract

The objective of paper is to describe and analyze the new orientation of educational technology in chemistry in the latest educational technology concept, empirical virtual learning, character building and soft skill development in the point of views. The analysis also was focused on research domain which reform mindset of educational technologist from predictive research to design-based research.
