Step 3: A high-intensity ultrasonic processor (Vibra cell 75186) equipped with a 2 mm microtip with variable power was used (maximum power, 130 W). A 20 kHz pulse mode was used for the dispersion and fragmentation of silica ribbons. Silica ribbons (2 mg) were mixed with 2 mL of i-PrOH and sonicated for 15 min with pulses of 1 s, separated by 1 s pauses. Samples were cooled in an ice bath during the sonication process to avoid solvent evaporation and an increase in the sample temperature, which could influence the fragmentation process.
