Surface tension measurements in microgravity and their relevance to Marangoni convection.
The physical properties of liquids, such as surface tension, Marangoni convection and surface segregation are important in many technical fields and are of fundamental interest. However, inaccuracy of experiments has prevented us from fully understanding these phenomena. Recent advances in experimental techniques, such as the containerless technique and the utilization of microgravity, are described.
