The discovery of Carbon Nanotubes by Sumio Iijima in 1991 was a significant milestone. These cylindrical molecules have remarkable mechanical, electrical, and thermal properties, making them useful in various applications, from electronics to materials science. Another groundbreaking innovation is the development of Graphene, a single layer of carbon atoms arranged in a hexagonal lattice. Discovered by Andre Geim and Konstantin Novoselov in 2004, graphene has unparalleled strength and conductivity, earning the researchers a Nobel Prize in Physics in 2010.
