Interactions of ionic species, (organic and inorganic) precipitates, and fine solids with a low energy hydrophobic surface were examined using a model system of paraffin wax in aqueous solutions. Contact angle measurement was used to evaluate the interactions between paraffin wax and testing variabl
Contact angles of diiodomethane, bromoform, water, formamide, and glycerol were measured on cholesterol surfaces both bare and precontacted with bile salts (sodium cholate, sodium deoxycholate, and sodium chenodeoxycholate). Ten different sets of the measured contact angles were used for the calcula
## Abstract Contact angle of water and formamide droplets on natural quartz crystals were observed. The specific surface free energy (SSFE) of m, r, and z faces, calculated using the Fowkes approximation, were approximately 54β69 mN/m. The length of the normal line from the center of the crystal to
The generally accepted strategy of neglecting the polar nature of halogenated liquids in the surface energy determination using the Lifshitz-van der Waals/Lewis acid-base (LW/AB) approach may lead to erroneous and inconsistent results for polar solids. This was demonstrated in a simulation study car
