Summary: Nitrogen-doped graphene quantum dots embedded in CuCo-LDH hierarchical hollow structure were synthesized to optimize the nanostructure of layered double hydroxide and alleviate agglomeration issues. The ordered multi-component structure effectively prevented aggregation and improved electron and ion transfer. The addition of nitrogen-doped graphene quantum dots further enhanced electron transmission rate and energy storage capacity, resulting in a specific capacity of 1009 F g-1 at 1 A g-1 and an energy density of 58.6 Wh kg-1 at 850 W kg-1 for the assembled CC@CuCo-LDH/NGQDs//AC device. These results demonstrate the effectiveness of the hierarchical structure and electrical conductivity in enhancing the electrochemical characteristics of asymmetric supercapacitors.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
