High and Low Density Patches in Simulated Liquid Water

It’s all in the void!

Time ago we looked at density fluctuations in liquid water, particularly the formation of cavities within the molecular network. Why? Because those are related to the cavitation free energy, which in turn is quite important when talking solvation and hydrophobic interactions. Here, we have taken a step further, identifying low- and high- density “patches” of water: yep – it turns out these cavities are not just randomly distributed throughout the liquid… there is more to come, I promise, but for now, have a look at the manuscript online – or just grab a pdf!
