Article Synopsis
- A molecular dynamics simulation was used to study the force between two moderately hydrophilic planar substrates connected by a nanoscale water bridge, showing that the force varies continuously with distance except for small gaps where it becomes erratic.
- The analysis revealed oscillatory forces and an increasing repulsive force when the substrates get very close, attributed to water molecules not maximizing hydrogen bonds at these small separations.
- The simulation results align well with findings from other methods and accurately reflect experimental force measurements, though traditional force balance theories only partially explain forces in purely water-based bridges.
