Confinement induced new phases of water

Water trapped between membranes or in tiny ‘nanoscale’ cavities is very common – it can be found in everything from membranes in our bodies to geological formations. But this nanoconfined water behaves very differently from the water we drink. Until…

A positivity-preserving scheme for fluctuating hydrodynamics

Capillary wave spectrum for a liquid slab in equilibrium with its vapour, obtained from the hybrid positivity-preserving scheme and a standard upwind scheme, compared with the theoretical prediction. The small inset shows one of the configurations of the system with the liquid slab at the center and two rough liquid-vapour interfaces.
