Electrochemical Processing is essentially influenced by the mass transfer rate governed by natural convection accompanying the electrode reactions. JAMIC facility provided good opportunities to understand the effect of gravitational level to the initial state of non-equilibrium electrochemical processing including single metal electrodeposition and water electrolysis. Now, the non-equilibrium electrochemical processing of alloy or semiconductor nanowire arrays are focused. Free standing ZnO nanowire array has been successfully synthesized on ITO/FTO substrate by template-free method in Zn(NO3)2 aqueous solutions in the terrestrial experiment. Two types of electrode configurations were employed: (a) a horizontal cathode surface facing downward over an anode (C/A) and (b) an anode over a cathode (A/C). More uniform nanowires are synthesized in C/A configuration than in A/C. The coupling phenomena between multi-component diffusion process around nanowire and the shape evolution must be clarified.
