owing to their enormous potential applications. We have observed peculiar magnetic
Meissner effect in 2D Nb 2 C MXene leading to signatures of superconductivity in the
material with an onset transition temperature of 12.5 K. Systematically optimized chemical
etching process of bulk Nb 2 AlC MAX phase led to the formation of 2D Nb 2 C MXene as
confirmed using scanning electron microscope (SEM) and x-ray diffraction (XRD) indicating …
