Stöber method and its nuances over the years

3D printing of non-iridescent structural color inks for optical anti-counterfeiting

“…Monodisperse silica nanoparticles (SiO 2 NPs) with a diameter of 171 nm were facilely prepared through seed growth by employing the Stöber method with some modification. 60 Afterwards, SiO 2 @PDA nanoparticles of diverse sizes were synthesized by coating varying amounts of polydopamine (PDA) on the surface of the SiO 2 nanoparticles in a Tris-buffer (pH = 8.5), and the final diameters were about 180, 189, 195 and 208 nm, respectively (Fig. S1, Table S1†).…”

Springtail-Inspired Hierarchically Structured Polymer Films as Omniphobic Coatings for Directional Transportation of Liquids

“…Spherical silica colloids, with average diameters of 300 and 450 nm (<3% standard deviations), are synthesized following the well-established Stöber approach . The as-prepared Stöber silica colloids are cleansed in absolute ethanol through multiple dispersion/centrifugation cycles to remove any unreacted reagents and then dispersed in a mixture of ETPTA photocurable monomer and HMPP (1.5%) using a PT-MR 3100 ultrasonic homogenizer (Kinematic Polytron).…”

Preparation and characterization of H3PMo11O39@SiO2@g-C3N4 nanocomposite and using as heterogeneous effective catalyst for one-pot green synthesis of 4-hydropyran derivatives under solvent-free conditions

“…To cover the lacunary phosphomolybdate surface with silica gel and graphite carbon nitride, the Stober's method used to prepare the nanocomposites [43]. For this purpose, 0.1-0.4 g of PMo 11 , on the other hand, 0.5 g of silica gel and 0.5 g of graphitic carbon nitride added to a mixture of 20 mL of deionized water and 80 mL of ethanol by impregnation method and exposed to ultrasonic waves for 1 h to disperse the mixture nicely.…”
