According to LaMer diagram, a clearly separate of nucleation and grows step is required to synthesis of monodisperse nanoparticles. However, a critical mixing time Tc until the growth process is started, is not clear experimentally. In this paper, we prepared gold nanoparticles (GNPs) by liquid-phase reduction using citric acid on microfluidics with different flow rates. From relationship of the diameter of the prepared nanoparticle and the mixing time, Tc for the preparation of monodisperse GNPs was found for the first time.

The liquid phase reduction-heat treatment has been used to prepare V2O3nanoparticles in this paper. It is a novel method that the precursor was developed by Oxalic acid dehydrate (H2C2O4·2H2O) reduction of V2O5powder in anhydrous ethanol. V2O3nanoparticles were successfully obtained by thermal treatment of the precursor. The phase, composition, structure, and morphology of the as-obtained samples were verified by XRD, XPS, SEM and TEM measurements. Meanwhile, the possible formation mechanism of V2O3in the heat-treatment is briefly discussed by analyzing the DSC.
