## 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

Described herein is a two-phase nonempirical method for the determination of surface or interfacial tension of stationary systems that also allows the determination of drop correction factor. The method is based on the theoretical calculation of the drop profile associated with the maximum volume of
The maximum liquid drop volume (v(max)) is measured by using a back-suction micrometer syringe piston technique. Different very viscous liquids are measured by (v(max)) and (v(f)) methods to observe the effect of viscosity on tension measurement. No apparent viscosity effect was observed in surface
The maximum liquid drop volume (nu(max)) is measured using a back-suction technique with a micrometer syringe piston. The residual amount of liquid on the tip was determined and the tension data calculated from the theoretical correction factors are well in accordance with those from the falling dro
