Another experimental demonstration of the existence of Exclusion Zone waters near to a surface (in this case Nafion surface, but in biological systems all the water may be EZ water because the short distances between different surfaces of the structures.
" Experimental measurements of electrostatic potential and the bulk concentration of bisulfite anions in water close to Nafion (a proton - exchange membrane) interface have revealed jump - like changes of these characteristics at a distance of approximately 150 μm from the interface. Furthermore, the temperature behavior of the bisulfite anion concentration exhibits a sort of hysteresis loop, which can be regarded as a manifestation of multi-stability in the system. Additionally, it is experimentally shown that in the vicinity of Nafion interface the refractive index of water grows approximately by a factor of 1.1 as compared with the value in bulk water. The obtained results can be interpreted as evidence of the formation of a new phase in water adjacent to Nafion interface."
The paper also make a review on the existing experimental data about EZ water (mainly from Pollack et al.)
Some properties of Exclusion Zone waters are that colloid particles are effectively pushed out of the EZ, that EZ grows with time an more rapidly if is irradiated at a wavelength absorbed by that, and that curiously the EZ temperature is less than the equilibrium temperature in the bulk of water far from the EZ.
