In situ Observation of Unidirectional Dissolution process in Organic Alloy under Microgravity

Abstract

There has been an increasing interest in understanding the underlying mechanisms and obtaining accurate data on mass and heat transport in liquid. All terrestrial experiments are distored by gravity-driven flow, which makes it virtually impossible to carry out precise measurements. In the transparent organic crystal of succinonitrile-acetone binary alloy, transient behavior of unidirectional dissolution is directly observed in order to precisely determine diffusion-controlled mass transport properties in microgravity environment.
