“…Indeed, surfactants cause the electrostatic repulsion between surfactant-coated nanoparticles, which considerably decreases the particle agglomeration due to van der Waals interactions [115]. The surfactant-coated nanoparticles also reduce their Brownian motion because of their extended sizes.…”

“…Among the various nanofluid preparation methods, adding surfactants is efficient in homogeneously dispersing nanoparticles in base fluids. Surfactants [e.g., SDS (sodium dodecyl sulfate)] cause electrostatic repulsion among surfactant-coated nanoparticles, which significantly decreases particle agglomeration because of the van der Waals forces of attraction [105,106].…”

“…Nanoparticles exhibit completely new or improved properties based on specific characteristics such as size, distribution and morphology, if compared with larger particles of the bulk material of which they are made [1][2][3][4][5]. Nanoparticles present a higher surface-to-volume ratio with decreasing size of nanoparticles.…”

Persimmon (Diopyros kaki) leaf extract was used for the synthesis of bimetallic Au/Ag nanoparticles. Competitive reduction of Au 3+ and Ag + ions present simultaneously in solution during exposure to Persimmon leaf extract leads to the formation of bimetallic Au/Ag nanoparticles. UV-visible spectroscopy was monitored as a function of reaction time to follow the formation of Au/Ag nanoparticles. The synthesized bimetallic Au/Ag nanoparticles were characterized with energy dispersive X-ray spectroscopy (EDS), scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). SEM images showed that large Au/Ag particles of 50-500 nm were formed with some cubic structure, while pure Ag particles obtained by reduction of only Ag + ion were smaller with diameter of 15-90 nm and predominantly spherical. The atomic Ag contents of the bimetallic Au/Ag nanoparticles from EDS and XPS analysis were 36 and 71 wt%, respectively, suggesting that bimetallic Au core/Ag shell structure was formed by competitive reduction of Au 3+ and Ag + ions with Persimmon leaf extract.
