摘      要：The stable nanobubbles adhered to mineral surfaces may facilitate their efficient separation via flotation in the mining ***,the state of nanobubbles on mineral solid surfaces is still *** this study,molecular dynamics(MD)simulations are employed to examine mineral-like model surfaces with varying degrees of hydrophobicity,modulated by surface charges,to elucidate the adsorption behavior of nanobubbles at the *** findings not only contribute to the fundamental understanding of nanobubbles but also have potential applications in the mining *** observed that as the surface charge increases,the contact angle of the nanobubbles increases accordingly with shape transformation from a pancake-like gas film to a cap-like shape,and ultimately forming a stable nanobubble upon an ordered water *** the solid–water interactions are weak with a small partial charge,the hydrophobic gas(N_(2))molecules accumulate near the solid ***,we have found,for the first time,that gas molecules assemble a nanobubble on the water monolayer adjacent to the solid surfaces with large partial *** phenomena are attributed to the formation of a hydrophobic water monolayer with a hydrogen bond network structure near the surface.
