Stable ASWs were successfully fabricated within α-MnO2 nanorods.

Unoccupied Ag 4d orbitals enhanced ASW stability, while delocalized 5s electrons ensured conductivity.

A coherently oriented 3D array of ASWs (up to 1 μm long) was formed.

Temperature-dependent current-voltage characteristics revealed an insulator-to-metal transition.

Conclusions:

The developed ASWs are stable and conducting, overcoming previous limitations.
The observed insulator-to-metal transition suggests potential for thermal electrical devices.
This work demonstrates a viable method for creating stable atomic metal wires for advanced applications.
