Example 1: Oppositely Charged Polyelectrolyte/Surfactant Mixtures Interfacial properties of oppositely charged polyelectrolyte/surfactant mixtures have long been interpreted in an equilibrium framework

the H22 guide is collimated to a halo-free pencil beam of 1.5cm diameter. The neutron beam intensity at the target position is of 10 8 n.cm -2 .s -1 .

Here in the relaxor ferroelectric PZN-8%PT at an energy transfer of 3 meV measured on IN20 (kf = 3 Å -1 ).

dielectric permitivity, a strong piezoelectricity. We consider here the perovskites Pb(Zn1/3Nb2/3)O3 (PZN) and Pb(Mg1/3Nb2/3)O3 (PMN) and their solid solutions with PbTiO3. They have an average ABO3 perovskite ... possible to examine both there "waterfall" anomaly and elastic diffuse scattering at several temperatures. 1- the “Waterfall” anomaly ...

(A and B). FlatCone made it possible to discover a third grain misoriented by about 90º. Thus only 1/3 of the sample volume contributed to the measured neutron scattering. All this would have made the
