Synthesis of needle-like nickel nanoparticles in water-in-oil microemulsion

Effect of the thermodynamic properties of W/O microemulsions on samarium oxide nanoparticle size

“…Particularly, in a quaternary W/O microemulsion system, the water nanodroplets stabilized by both surfactant and cosurfactant provide confined reaction space, which can be actually utilized as microreactors for the synthesis of nanoparticles [7]. These microreactors provide not only the suitable reaction media but also an efficient method to define the size of nanoparticles by restricting the excess particle growth as the size of particles approaches to that of water nanodroplets [8].…”

Characterization of cobalt oxide nanocatalysts prepared by microemulsion with different surfactants, reduction by hydrazine and mechanochemical method

“…Cobalt carbonate nanoparticles were formed by mixing the appropriate volumes of two W/O microemulsion solutions with vigorous stirring at 500 rpm for 30 min. The precipitates were washed with ethanol to remove the undesirable contaminations [14]. The addition of hydrazine resulted in changing the color of solution from blue to brown-reddish brown.…”

One Pot, Solvent-Free Synthesis of Substituted 3,4-Dihydropyrimidin-2(1H)-Ones/Thiones under Microwave Irradiation (CEM) Using Reusable Nickel Nanoparticles

“…XRD graph (Figure 1) shows two characteristic peaks at 2ϴ value 45.37 &52.8 which were matched with standard data. [23][24][25] These peaks correspond to indices (1 1 1) and (2 0 0) respectively. The broad nature of peaks is indicative of their nano size.…”
