Absence of drop size dependence of contact angles of sessile drop systems is sometimes observed in experiments. The contact angle data sometimes fluctuate periodically about a horizontal line. Moreover, in cases where a drop size dependence of contact angles exists, the contact angle data often scat
Different patterns of drop size dependence of contact angles have been observed experimentally. Some investigators reported a decrease of contact angle with an increase in drop size, while others reported an increase. Still others reported that there is no drop size dependence of contact angles. The
## Experiments with different organic liquids have been conducted to study the drop size dependence of the contact angles on a self-assembled monolayer (SAM) surface of 1-octadecanethiol (HS(CH 2 ) 17 CH 3 ) on gold. Low-rate dynamic advancing contact angles were measured for sessile drops in vapo
