We propose a model elucidating the mechanisms at the origin of the density anomaly of water. We start from a model of … second critical point scenario. Since experiments on water show the presence of HBs correlation, this result suggests that …

The stability of ice I cubic (ice Ic) whose voids are occupied by neon particles is investigated using a hybrid type of isobaric grand-canonical Monte Carlo simulation. We show that the resulting neon hydrate is stable under high pressure and temperature where ice Ic alone is unstable,...

Whereas the rhodopsin blue rod water films are smoothest in humans, the red cone opsins …’ water films are optimized for smoothness in cats and elephants, consistent with protein species landscapes that evolve …

We investigate here the effect of temperature on the diffusion of water and cations in the Wyoming-type montmorillonite … interlayer ions and water molecules under a temperature range between 260 and 400 K. The diffusion coefficient of water and … cations in different hydrated clays increases with temperature. The influence of temperature on the diffusion of water is much …
