présentera en 1 heure :
''Thermophoresis describes the motion of the components of a complex fluid in a temperature gradient; the resulting non-uniform composition is known as Soret effect. After a brief overview of possible applications (microfluidics, hydrothermal pores, isotope separation...), we discuss the physical mechanisms, in view of recent experiments on charged particles, polyelectrolytes, and binary liquids.''
