I require a standard model / simulations [ original  or review articles ] on the nucleation and growth of iron oxide nanoparticles (IONP) [ without intervention of any surfactant / polymer / bio agents ] using chemical technique [ co-precipitation ]. I would like to analyze such model which can describe the effect of IONP synthesis parameters on particle size with strong justifications. I was more specific to know about the effect of synthesis parameters like Ion concentration, Fe2+:Fe3+ ratio , Alkali ratio , stirring speed , duration of addition and addition rate of alkali [ NH4OH NAOH ] on particle size (primary interest)  . Effect of temperature, atmosphere and ph are the secondary interest.
