When hydrophobic surfaces are in contact with water in ambient conditions a layer of reduced density is present at the interface, preventing the intimate contact between the two phases. Reducing the extent of this layer by degassing the water can have remarkable implications for the interaction between the two phases. The enhanced proximity between a(More)
We have investigated the 2D viscoelastic behavior of the reactive sol-gel transition of silica alkoxides deposited at the air/acidic water interface of a Langmuir trough by oscillatory interfacial rheology. The storage and loss moduli increased with time as the hydrolysis-condensation reaction took place. There was evidence of a 2D gel point, which was(More)
