Science of Multiphase Interface:Nanoscopic Viewpoints

概要

The phenomena occurring at a nanoscopic scale on the very surface of solid substrates are discussed, as one particular aspect of multiphase flow studies. The STM (scanning tunneling microscopy) observation as well as the newly developed total reflection X-ray diffractometry experiments revealed the nanoscopic behavior of organic molecules from vapor to solid phases (crystallization process), whichd epends greatly on the nature of the substrates, namely on the interaction between the molecules and the substrate atoms. It is suggested that such interactions, including the electrostatic intermolecular interaction, play an essential role in the aggregation process of molecules above solid surfaces, as indeed simulated by a computer calculation. Moreover, the possible correlation of these nanoscopic mechanisms to the macroscopic multiphase flow behavior is discussed.
