The influence of electrowetting on the behavior of impacting droplets
... the surface. The wettability of a surface is the quantification for the degree of hydrophobicity or hydrophilicity of a surface. [1] Applications of electrowetting can be found in adjustable lenses, electronic displays like e-readers, but also in combination with the coffee stain effect. Next to tha ...

Derivation of the BET and Langmuir Isotherms
... The BET isotherm is accurate when P/Po is between ∼0.05 and ∼0.3, pressures at which only a few complete layers have formed. At low pressures the BET isotherm does not do a good job at describing adsorption because in deriving the isotherm it was assumed that all the sites on the alumina surface are ...

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.
