Surface capturing

Another type of condensation, called dropwise, occurs when the wall is not uniformly wetted by the condensate, with the result that the condensate appears in many small droplets at various points on the surface. There is a growth or individual droplets, a coalescence of adjacent droplets, and finally a formation of a liviilet. Adhesional force is overcome by gravitational force, and the rivulet flows quickly to the bottom of the surface, capturing and absorbing all droplets in its path and leaving dry surface in its wake.

The outermost layer of the solid molecules on the surface is bound on only one side to the inner layer of molecules by atomic and molecular forces. To compensate for this imbalance of the binding force, an attraction force from the solid surface captures the surrounding gas, vapor, or liquid. This attraction can be either physical or chemical, depending on the temperature and the interacting forces between the solid and the surrounding fluid. 

Pfeifer, Wely, and Wippermann1671 examined surface portions of a lysozyme protein molecule. A fractal dimension of D = 2.17 was determined and related to the rate of substrate trapping at the enzyme active site. The root mean square substrate displacement via diffusion at the surface increases as time (t)1AD whereas surface capture of substrates is greater when compared with a smooth (D = 2) surface. From their results, the authors suggested that the observed value of D = 2.17 corresponds to an optimum overall capture rate. 

The nett surface capture rate ovNt can be estimated by assuming a corresponds to atomic dimensions a 10"16cm2 if v 107cms andiVt 1013cm 2, we have avNt K cms 1, which is a substantial rate constant. 

It appears that TiO2 particles in water are widely hydroxylated. Therefore holes escaping annihilation may migrate to the surface and oxidize adsorbed water molecules and hydroxyl ions. Oxygen adsorbed at the surface captures electrons preventing their recombination with h and therefore favouring the yield of OH radical (Fig. 5).

Adhesion of Particles Together with Drops of Water to a Solid Surface. In periods of rain, drops of water may capture dust particles suspended in the air. Such processes are employed in water curtains [220, 221] for dust suppression, The particles here fall on the surface at the same time as the drops of water. There is also another possibility in which drops of pure water fall on a dust-laden surface, capture adhering particles, and remain fixed to the surface together with these.
