  The present work reports on the scale up of synthesis of CuO nanoparticles from two different precursors: Copper (II) nitrate and copper (II) acetate. This is in realization of the importance of scale-up procedures for synthesis of nanoparticles with an ultimate aim to extend the application of nanoparticles for large-scale industrial applications. Our results show that the reaction batch volume can be scaled up to 5000 mL at a yield of 42 g per batch, without loss of morphological and crystallographic features. While using copper (II) acetate as precursor, higher yield and control of particle size can be achieved through re-use of spent precursor solution.

  Experimental studies on heat transfer in a jacketed vessel were carried out to test the performance of two nanofluid coolants, viz. Mn0.47Fe2.53O4-propylene glycol (2 vol%) and CuO-propylene glycol (1 vol%) nanofluids, against pure propylene glycol. The flow rate of process fluid (Therminol-55®) flowing through the jacket was varied between 60-500 mL min-1. In general, these nanofluids were able to reduce the outlet temperature of process fluid to values lower than that achieved using pure propylene glycol. These nanofluids are more effective at higher flow rates of process fluid due to their improved transport properties.
