Thio- and selenoureas can be conveniently prepared in single steps from commercially available starting materials. By adjusting their organic substituents, the rate of their reaction with metal surfactant complexes can be adjusted and a desired nanocrystal size can be prepared in quantitative yield without otherwise adjusting the crystallization medium. Using this method of tuning the rate, we have probed the temperature dependence of nucleation and growth steps. I will describe our current understanding of homogeneous nucleation and growth mechanisms and the important role of precursor conversion kinetics in homogeneous nucleation and growth processes.<br/>
