Graphene: The Wonder Material Changing the Game
Graphene, a single layer of carbon atoms arranged in a hexagonal lattice, is often hailed as a "wonder material" due to its exceptional properties. Its discovery in 2004 by Andre Geim and Konstantin Novoselov at the University of Manchester, who later won the Nobel Prize in Physics for their work, has sparked a revolution across various scientific and technological fields. This article delves into the unique characteristics of graphene and its transformative impact.
What Makes Graphene Extraordinary?
Graphene boasts a combination of properties unmatched by other materials:
- Exceptional Strength: Graphene is approximately 200 times stronger than steel, making it one of the strongest materials ever tested.
- High Conductivity: It exhibits remarkable electrical and thermal conductivity, surpassing that of copper and silicon.
- Flexibility: Despite its strength, graphene is incredibly flexible and can be bent and stretched without breaking.
- Transparency: Graphene is nearly transparent, absorbing only 2.3% of light.
- Impermeability: It is impermeable to all gases, including helium.
Applications Across Industries
