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.
During the synthesis of ZnO NPs via assisted microwave method (800kW, 5 mins), should we add all the NaOH solution (250mL, 0.5M) to the zinc acetate solution (250 mL, 0.2M) under constant...
