We present a comprehensive approach to address the correlation between mechanical properties of nanowires (NWs) with their characteristic size, microstructure, and chemical composition. Using this technique, the Young’s modulus of Co₃O₄ NWs with different sizes was evaluated. Thermal annealing in inert atmosphere was found to induce chemical reduction of as-grown Co₃O₄ NWs into CoO NWs without modifying their geometrical shape. Both Co₃O₄ and CoO NWs exhibited a size-dependent variation in Young’s modulus.
