I manage to use 4 different minerals of the same rock, they give me 4 different ages. As I know they had a different temperature of formation, I was able to recover how that rock came to the surface of Earth and prove the existence of a micro-continent around 3 billion years ago.
I stumbled across a greener (minimum amount of chemicals) technique to fabricating optical lenses and gratings that are very tiny and compact, and that can be used in a lab-on-a-chip.
