Formation of silver bromide precipitate of nanoparticles in a single microemulsion utilizing the surfactant counterion

“…1 shows a broad spread in the particle distribution with a relatively high percentage of particles with large diameter, dp > 11 nm. This observation suggests that the intermicellar nucleation was slow and that particle growth and nucleation took place simultaneously [14,25]. The low rate of intermicellar nucleation probably resulted from a rigid surfactant layer at the values of the experimental variables used in this study.…”

“…3a-3c show that as the surfactant concentration increased at fixed R, the particle size increased, and the particle size distribution became broader. These results suggest that with increasing the surfactant concentration, fewer nuclei formed and nucleation and growth took place simultaneously [14,25]. Fewer nuclei may have formed as a result of a decrease in the Ag + ion occupancy number; i.e., the number of moles of Ag + per reverse micelle, and a subsequent decrease in the AgBr monomer concentration inside the reverse micelles to a concentration below the critical nucleation concentration.…”

“…The low rate of intermicellar nucleation probably resulted from a rigid surfactant layer at the values of the experimental variables used in this study. Studies on the effect of the surfactant, cosurfactant, and reactant concentrations and the type of organic continuous phase on the particle size and particle size distribution are available elsewhere [6,14,[25][26][27].

Microemulsion-Aided Synthesis of Nanosized Perovskite-Type SrCoOx Catalysts

“…Both microemulsions were combined in a semi-batch process (3 mL min -1 ) at 303 K under vigorous stirring (1,000 min -1 ). The precipitation of oxalates immediately occurs during the combination of the microemulsions as reported by Schmidt et al [21]. After complete addition of microemulsion A, the reaction mixture was stirred for further 30 min.…”

Ru(bpy)32+‐doped Silica Nanoparticle Aptasensor for Detection of Thrombin Based on Electrogenerated Chemiluminescence

“…The 2 3 Ru(bpy) ＋ -doped SNPs synthesized by a W/O microemulsion method were highly monodispersed 40 and extremely uniform in size, with the average diameter of (90±5) nm as 100 nanoparticles were measured by a transmission electron microscope reported by our group. Ru(bpy) ＋ -doped SNPs had an obvious pair of redox peaks of 2 3 Ru(bpy) ＋ on the CV curve and the ECL intensity of 2 3 Ru(bpy) ＋ -doped SNPs was enhanced in the presence of TPrA.…”
