The characterization of aprotic polar liquids and percolation phenomena in DMSO/water mixtures

The interpretation of the percolation effects leads to the following conclusion: DMSO/water mixtures seem to have in the whole range of miscibility the same microscopic structure like water with a coordination number z≈ between 4 and 6 which could be the reason for the high permeability of DMSO through biological membranes.(1)ETN=ET(solvent)−ET(TMS)ET(water)−ET(TMS)=ET(solvent)−30.732.4
