Size distributions of FeAu alloy nanoparticles generated in (a) acetone, (b) MMA, and (c) water. The number-weighted particle size distributions were fitted with a log-normal function. (d) Hydrodynamic diameters (dh), zeta potentials (ξ), and Feret diameters (df) of FeAu nanoparticle colloids in different solvents (ξ could not be measured in MMA because of high viscosity). The df values were obtained from the number mean values of the log-normal fitting functions.
