monodispersed 中文意思是什麼
monodispersed
解釋
單分散的-
Monodispersed particles may be synthesized by thermal decomposing iron pentacarbonyl in liquid phase containing lauryl - phosphate mono - ester as the surfactant. with increasing dosage of the surfactant, the grain size of the particles decreases, as a result, the permittivity decreases and the permeability increases. the minimal permittivity and the maximal permeability occur at the diameter of about 39 nm
