SCIENCE - Physics duo offer explanation of why tiny bubbles last longer on a surface

(Phys.org)-Physicists in The Netherlands, Detlef Lohse and Joost Weijs of the University of Twente, have offered an explanation of why nano-sized bubbles last considerably longer when sitting on a solid surface covered by a fluid, than when they are allowed float free. In their paper published in Physical Review Letters, the two argue that surface-held bubbles have increased radii of curvature and sit in pools of liquid infused with gas, which causes them to last longer.
