Description

Fluids play a main role in determining the final structural and transport properties in several solvated systems like hydraulic binders[1], hydrogels[2], organogels[3] and colloids in general. Thanks to their peculiar neutron-sample interaction, neutrons are the elective probe to study many hydrogen-rich systems. For this reason, neutron scattering techniques are unique in defining porous matrix topology at the nanoscale and relaxation properties in the ps-ns regime. This presentation reviews few examples were neutron scattering, even in time-resolved mode, could be of great advantage for the material intrinsic understanding and improvement.
