We are going to synthesize ZnO Nps using calamansi peel extract using NaBH4 and Zn(NO₃)₂ what would be the best way (we are thinking of chemical precipitation) to do it? also the amount needed to synthesize it.
Favourable conditions of base pressure, rate of deposition. Also, by which characterisation technique to be used to verify the thickness of the deposited film.
