    Experiment Description

    Research Overview

    • Precise information for Soret coefficient was not performed due to  the experimental constraints in relation with the convection control on the ground. 

    • We will obtain the precise information of  the Soret coefficient with a laser spectroscopic technique facilitated at SCOF in the JEM. 

    • Since the research focuses on the Soret physics under steady/non-steady/transient condition including supercooled liquid phase. It will be the first verification result to link the Soret physics and thermodynamics. It also produces the first bench mark result that consider on convection control on the ground by comparing  identical data (1G/microG).
