Experimental activities

by Guillaume Mériguet - 22 February 2010

All the versions of this article: English , français

The experimental activities can be divided into two groups:
- the ones developed within the laboratory PECSA,
- the ones carried out in Large Facilities

In the laboratory

Measurements of dynamic properties using radioactive tracers have been performed in the laboratory since its inception by Professor Chemla in 1967 (Laboratory of Electrochemistry then). They are currently used to investigate the kinetics of liquid / liquid extraction.

In recent years, the laboratory also has also invested in several devices allowing the determination of electrokinetic parameters:
- high precision conductimetry,
- acoustophorometry, ,
- laser zetametry. .

In addition to these techniques, complementary methods also available in the laboratory such as Atomic Force Microscopy (AFM) and Dynamic Light Scattering (DLS).

Finally, our team includes since September 2008 an emeritus professor , B. Ancian, whose specialty is the measurement of interactions and dynamical phenomena with Nuclear Magnetic Resonance.

Large Facilities

Experiments performed in Large Facilities are mainly measurements of neutron or X-ray scattering. The group submits (and is granted) every year several proposals for beam time in the Laboratoire Léon Brillouin in Saclay and in the Institut Laue Langevin in Grenoble to perform of small angle scattering experiments: neutron spin echo spectroscopy and quasielestic neutron scattering. Given the spatial and timescale, results of such experiments can conveniently be compared with correlation functions calculated by numerical simulations.
