Workpackage No 4

Work package number and title:

4. Training of junior IPUL researchers abroad in the field of magnetic fluids

Type of activity: 
Junior training abroad (VR)
Relative start month: 6
Timetable: First year - 2 month, second year- 2 month, third year- 1 month (altogether 5 months)


  1. Research program of Institute of Physics on magnetic fluid includes experiments on thermal grating of colloidal particles in thin fluid layers. This is a very powerful technique for investigation of magnetic field effects on particle thermophoretic transfer. For colloid research this method is quite new, whereas in experiments with binary mixtures of ordinary liquids and polymer solutions the Forced Rayleigh Scattering (FRS) technique is used already for several years. We propose to organise a research visit of the junior researcher to the Institute of Physics, University of Bayreuth (Prof. W. Koeler). The training will allow a learning of newest methods for measurements of spectral characteristics of the grating relaxation processes. Such technique is very useful and informative to investigate anisotropic mass transfer processes in ferrocolloids and will significantly support our activities planed in the work package WP11 as well as will allow us to plan experiments related to WP18.
  2. Presently the considerable attention is being paid to the investigations of the different aspects of the hydrodynamics of the interface between miscible fluids that is motivated by numerous applications. The influence by the external fields on the dynamics of the interfaces between miscible fluids opens new opportunities for pharmacology and chemical industries. According to the present workplan investigation of the different microconvection phenomena arising under the action of the external field on the diffusion front will be carried out. World-wide leaders in the investigation of the magnetic colloids is the ferrofluid group of Prof.J.-C.Bacri in D.Diderot University Paris 7 and ESPCI (Prof.P.Petitjeans et al.) in investigations of the dynamics of the interface between miscible fluids. Work in those centers is crucial for training of the PhD student.
