“…However, for the latter two waters, their preparation methods differed from that of water perturbed by CE. Therefore, after finishing the current study, we investigated the properties of perturbed water, which was prepared with the same method as that of waters perturbed with CE or Nafion, yet we employed another type of cellulose sheet, i.e., paper filter [37]. The water repetitively perturbed with paper filter also contains organic compounds.…”

We present experimental data on water repetitively brought in contact with cellophane. Although this hydrophilic polymer is insoluble in water, repetitively immersing it in water changes the liquid's properties. We compare the physicochemical properties of the water left over after removing the cellophane to those of previously published data on water repetitively brought in contact with other in water insoluble polymers (cotton wool or Nafion). Some of the properties are similar. All the properties considerably differ from those of the Milli-Q ® water used. On lyophilizing these waters, solid residues remain. The residues are soluble in water. The chemical nature of the residues differs from that of the perturbing polymers.

“…The iteratively perturbed water (IPW) has physicochemical properties commensurate with its clumps containing H 2 0 CD elec and CD rot (Elia et al, 2015(Elia et al, , 2017Yinnon et al, 2016). Some of these properties, e.g., the optical activity or pH, are perturbing membrane specific (Elia et al, 2018(Elia et al, , 2019. Accordingly, it is plausible that water flowing adjacent to various types of hydrophilic cellulose (a common phenomenon in nature) contains H 2 0 CD elec and CD rot , with perturbing membrane specific vortices.…”

Altering the bioactivity of aqueous solutions via serial dilutions is important for toxicology, medicine and wastewater treatment. Extensive research has shown that serially diluting aqueous solutions beyond a threshold concentration, combined with vigorous shaking after each dilution step, has several notable effects. (a) The solutes may serve as substrates, which facilitate association of water molecules (10 -5 and 10 -7 m sized associates). (b) The associates and the bioactivity of these liquids persist when these fluids are diluted below 10 -24 mol/liter. (c) The associates and the bioactivity of these liquids disappear when such ultra-diluted fluids are screened from ambient electromagnetic radiation. (d) The structural and physicochemical properties of these liquids are explainable within the context of quantum electrodynamics (QED). Hitherto, relations between the physicochemical properties of these liquids and their substrates have not been unveiled. There are no reports of statistically significant data that reflect physicochemical aspects of these liquids attributable to specific characteristics of substrates. Moreover, the aforementioned relations have not been theoretically derived. In this study, the relations are ana-lyzed within the context of QED. The analyses have helped elucidate the challenge of observing the impact of the substrate on the associates. The analyses also indicate that measuring the quantum Hall effect of these liquids holds the promise of unveiling the aforementioned relations.

“…A few researchers have proposed that the EZ is due to a change in water’s structure [ 12 , 39 , 40 , 41 , 42 , 43 , 44 ]. One problem with this is there are no obvious thermodynamic forces in the system to drive such a phase change or long range ordering, and such effects are not observed in conventional molecular dynamics simulations.…”

“…Elia et al suggest that perturbations near the EZ surface can cause clumps of EZ water to disperse in the bulk liquid, resulting in changes that can be detected in the bulk liquid as the EZ water clumps dissipate [ 43 ]. Figuera and Pollack have presented a somewhat similar argument, arguing that the stable nature of the EZs under perturbations must be due to a structure change [ 40 ].…”

The existence of the exclusion zone (EZ), a layer of water in which plastic microspheres are repelled from hydrophilic surfaces, has now been independently demonstrated by several groups. A better understanding of the mechanisms which generate EZs would help with understanding the possible importance of EZs in biology and in engineering applications such as filtration and microfluidics. Here we review the experimental evidence for EZ phenomena in water and the major theories that have been proposed. We review experimental results from birefringence, neutron radiography, nuclear magnetic resonance, and other studies. Pollack theorizes that water in the EZ exists has a different structure than bulk water, and that this accounts for the EZ. We present several alternative explanations for EZs and argue that Schurr’s theory based on diffusiophoresis presents a compelling alternative explanation for the core EZ phenomenon. Among other things, Schurr’s theory makes predictions about the growth of the EZ with time which have been confirmed by Florea et al. and others. We also touch on several possible confounding factors that make experimentation on EZs difficult, such as charged surface groups, dissolved solutes, and adsorbed nanobubbles.
