Footprints found in New Mexico were dated to roughly 23,000 years old - about 10,000 years before humans were thought to be ...

While traditional liquid-phase printing methods can produce graphene patterns with a resolution of ∼30 μm, more precise techniques are required for improved device performance and integration density.

Synthetic examples and field data show that the SSGST achieves a high resolution and has the potential in highlighting geological structures with high precision.
