Surface chemistry and Catalysis
... Here we are considering physical adsorption resulting in the multi layer adsorption. In BET it is assumed that the solid surface possesses uniform, localized sites and adsorption at one site does not affect adsorption at neighboring sites . It is further assumed that the molecule can be adsorbed in ...

... Barnocky and Davis [8] studied the drainage between fluid spheres with arbitrary viscosity, from bubbles to rigid particles. The influence of surfactant and the surface tension gradient were not paid any attention. In our case, the droplet at rest is covered with surfactant and is therefore handled ...

Therefore the osmotic pressure after the CMC will increase very gradually. Determinations such as these are not common as the method is ...

Ultrahydrophobicity
Superhydrophobic surfaces are highly hydrophobic, i.e., extremely difficult to wet. The contact angles of a water droplet exceeds 150° and the roll-off angle/contact angle hysteresis is less than 10°. This is also referred to as the Lotus effect, after the superhydrophobic leaves of the lotus plant. Droplet impacting on these kind of surfaces can fully rebound like an elastic ball, or pancake.
