"integrates transient electric field (kinetic electrodeposition coefficients 3.5−4.3X better than TE alone) and swirling flow (1.37−1.97X better than SF alone) improving mass transfer and promoting interfacial ion transport simultaneously... copper recovery achieved with low and high electric levels of 0 and 4 V, 50% duty cycle, 1 kHz frequency, and 400 L/h flow rate... recovers with homogeneous compositions and uniform morphologies with redox potentials higher than those of hydrogen evolution and water reduction"
