  Using molecular dynamics, we study the nucleation and stability of bulk
nanobubble clusters. We study the formation, growth, and final size of bulk
nanobubbles. We find that, as long as the bubble-bubble interspacing is small
enough, bulk nanobubbles are stable against dissolution. Simple diffusion
calculations provide an excellent match with the simulation results, giving
insight into the reason for the stability: nanobubbles in a cluster of bulk
nanobubbles "protect" each other from diffusion by a shielding effect.
