Most theories regarding the behavior of intermolecular forces assume perfectly smooth surfaces with well-defined chemical and material properties. In this thesis, three separate systems are studied to explore the accuracy of this assumption in very different situations. In the first system, the effects of milli-molar amounts of dissolved gas (the amount typically present in normal atmospheric conditions) have been studied at a pristine oil/water interface. It was found that the removal of the dissolved gas significantly increased the lifetime of the oil droplets, effectively reducing the long-range hydrophobic attractive force present under standard conditions.... diameter was selected to fit tightly inside the measuring cavity of a Micro 100 Laboratory Turbidimeter (Nephelometer, ... The water used was produced from tap water purified via a Millipore unit (Elix water purification unit, from Millipore SA, anbsp;...
