Anomalies in H2O-D2O mixtures: Evidence for the Two-Fluid Structure of Water

TL;DR

This paper presents evidence supporting a two-fluid microscopic model of water based on anomalies observed in H2O-D2O mixtures through various experimental techniques.

Contribution

It introduces a novel two-fluid microscopic framework for understanding water's properties, explaining experimental anomalies related to isotopic composition.

Findings

Anomalous physical quantities depend on isotopic mixture composition.

A two-fluid model explains the electromagnetic interactions influencing water.

Experimental data supports the two-fluid microscopic structure hypothesis.

Abstract

Recent probing of H2O-D2O mixtures by various means (neutron deep-inelastic scattering, Raman absorption, electrical H+/D+ conductivity) revealed an unexpected dependence of the relevant physical quantities on the isotopic composition of the mixture. We show that these observation can find their physical rationale in the context of an approach to the physics of liquid water which takes into account the non-negligible interaction of the molecules with the electromagnetic field, from which a two-fluid micro- scopical picture of water naturally emerges.
