Solubility of cadmium sulfate in H2O-D2O mixtures

Physical limit of stability in supercooled D2O and D2O¿H2O mixtures

The fluctuation theory of homogeneous nucleation was applied for calculating the physical boundary of metastable states, the kinetic spinodal, in supercooled D2O and D2O1H2O mixtures. The kinetic spinodal in our approach is completely determined by the surface tension and equation of state of the supercooled liquid. We developed a crossover equation of state for supercooled D2O, which predicts ...

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

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 observations can find their physical rationale in the context of an approach to the physics of liquid water which takes into acco...

Search for anomalous scattering of keV neutrons from H2O-D2O mixtures.

We measured the neutron scattering intensities from pure liquid H2O relative to that of pure D2O and also relative to H2O-D2O mixtures, at room temperature. This study is relevant to the problem of quantum entanglement. The neutrons were generated from an electron Linac and the final energy of the scattered neutrons was fixed at 24.3 keV using a 20 cm thick pure iron filter. The scattering inte...

Photodesorption of Ices Ii: H2o and D2o

Gaseous H2O has been detected in several cold astrophysical environments, where the observed abundances cannot be explained by thermal desorption of H2O ice or by H2O gas phase formation. These observations hence suggest an efficient non-thermal ice desorption mechanism. Here, we present experimentally determined UV photodesorption yields of H2O and D2O ice and deduce their photodesorption mech...
