A molecular dynamics study of the force between planar substrates due to capillary bridges

Computer Simulation of the Effect of Wetting Conditions on the Solvation Force and Pull-Off Force of Water Confined between Two Flat Substrates

“…The capillary bridges have been studied for various systems using Monte Carlo and molecular dynamics (MD) simulations. ,− Among other results, these studies have shown that the force obtained using computer simulation can be quantitatively compared to the experimental results. As an example, Salameh et al calculated the force between two TiO 2 nanoparticles connected by a water bridge using MD simulation with excellent agreement with experimental AFM measurements.…”

Molecular Dynamics Simulation of Nanoforces between Substrates Mediated by Liquid Bridges: Controlling Separation and Force Fluctuations

“…The slope of the curve changes significantly between consecutive red points at separation distances less than 2 nm, with a minimum force at 1.7 nm, which may suggest that the attraction of the substrates due to the argon bridge is maximum at that distance. However, it is known that liquid argon is organized in layers under confinement (see, for example, refs and ). In fact, density profiles of liquid argon confined at D = 0.9, 1.3, 1.7, and 2 nm show three, four, five, and six layers, respectively.…”

“…The great interest in force–distance curves and in particular its components is evident from the extensive literature on laboratory experiments − and also from the growing literature on computational simulation. − AFM and related techniques such as friction force microscopy, chemical force microscopy, and dip-pen nanolithography are amenable to simulation because both force and displacement measured are of the order of magnitude covered by the simulations. The most used simulation techniques in the determination of force–distance curves include molecular dynamics (MD), − Monte Carlo (MC), − , classical continuum, ,,,− and hybrid methods. , These techniques are also useful for testing interaction potentials. Recently, we used molecular dynamics simulation of a nanoscale capillary water bridge amidst two planar substrates to determine the resulting force between the substrates with no arbitrariness on the geometry and location of the free surface of the bridge …”

Droplets sliding over shearing surfaces studied by molecular dynamics

“…20 Interaction between liquids and substrates is also of key importance in the formation and rupture of liquid bridges. 21,22 As noted above, Boek and coworkers are prominent in the application of MD simulations in the field of (enhanced) oil recovery. 6,7 This article is organized along the following lines: in the next section, the model system, its geometry, the simulation approach, and the (dimensionless) parameter space covered are introduced.…”
