[Display omitted] •Instantaneous reduction in ambient pressure generates interfacial nano-micro bubbles (INMBs).•The INMBs show promotional and depression effects in the NaOl and DDA systems, respectively.•INMBs “clean” the adsorbed reagents on the apatite surface.•Single INMBs cannot stabilize the...
