Surface and hydrodynamic forces acting between an air bubble and a flat mica surface in surfactant-free water and in 1 mM KCl solution have been investigated by observing film drainage using a modified surface force apparatus (SFA). The bubble shapes

Graphical abstract In water, bubble slides along glass wall faster than in salt solution. Highlights ► The terminal velocity of bubble sliding along glass wall varies with salt concentration. ► The first demonstration that terminal velocities of

Film thinning experiments have been conducted with aqueous films between two air phases in a thin film pressure balance. The films are free of added surfactant but simple NaCl electrolyte is added in some experiments. Initially the experiments begin

Frictional behaviors between mica surfaces have been investigated with the Surface Force Apparatus under various relative vapor pressures (RVP) of both water and cyclohexane. The dependence of frictional forces on RVP, particularly in the low RVP ran

Frictional behaviors between mica surfaces have been investigated with the Surface Force Apparatus under various relative vapor pressures (rvp) of both water and cyclohexane. Stick-slip frictional behaviors were observed only under cyclohexane vapor.

Our developing method "quantitative friction map" enables us to compare the spatial distribution of friction forces on the surface among separately scanned samples sensitively. We applied this technique to evaluate the friction acting between mono-[6

High molecular weight poly(p-hydroxystyrene) (PHS) was dendronized in high yield by the divergent grafting of aliphatic polyester dendrons using acetal and ketal protected anhydride derivatives of bis(hydroxymethyl)propionic acid. Relatively low poly

The effect of the shear flow on the thickness change of a polyelectrolyte membrane grafted onto a glass substrate was directly investigated with a flow cell combined with a confocal laser scanning microscope. The membrane thickness decreased proporti

It has been long believed that modern physics fails in explaining the forces measured between hydrophobic surfaces. We show that the dispersion attraction and cavitation between two uncharged strongly hydrophobic surfaces agree with the classical cap
