10. The two-step acid-base catalyzed process consists of a prehydrolyzed solution, which is prepared in acidic conditions in the first step favoring the hydrolysis but not the condensation reaction, and in the second step this sol is treated with a basic solution.
11. Substrate surface treatment consisted of a sequence of two minute washings in an ultrasound bath, first with acetone, followed by a washing with a KOH (0.1 M) solution and a final rinsing with ethanol.
