Glass transition in microemulsions
Microemulsions of simple liquids can be cooled at moderate quenching rates down to 0 K without demixion. The glass transition of liquids that normally crystallize (such as xylene or benzene) can be observed because of the very small size of the systems, which makes the nucleation probability much smaller than in the bulk, and of the decoupling between their characteristic relaxation times and the viscosity of the aqueous matrix. We characterize by small-angle neutron scattering the structure of these emulsions, using diluted samples.
