A model assuming that the formation of dimers determines the acoustic properties of liquid mixtures, in the inert solvent cyclohexane, was applied to describe the observed dependences of sound speed on composition. The dimerization constant...
Composition of Surface Layer at the Water-Air Interface and Micelles of Triton X-100 + Rhamnolipid Mixtures [0.03%]
