Outline of Final Research Achievements

Oriented aggregation, known as a non-classical pathway for crystal growth mechanism, rarely occurs as single mechanism. The previous work demonstrated the possibility by controlling dissolution rates of the starting materials, and which afforded a high-quality inorganic crystal. Thus we tried to found the guiding principle for routine use. The kinetic control of the reaction system invoked single crystallization of NiMoO4-0.75H2O nanowire, which showed higher capacitor performance than that for conventional NiMoO4 hydrate nanowire, through the oriented aggregation.
