What atoms do when liquids and gases meet

NanoWerk.com - Tue, 01/22/2019 - 14:01
Until now, it was thought that the atoms in these regions behaved as if they were in a 'drum skin', based on the assumption that the surface tension between the two elements caused the water to be drawn taut like a drum and to act as such when disturbed. Although this is correct on larger scales, the assumption fails on smaller scales.
