A ballistic test showed that graphene can absorb twice the impact of bullet shots compared to the current material used in bulletproof vests. Graphene is a very thin and nearly transparent sheet of pure carbon. It is lightweight, but 100 times stronger than steel. Scientists have been studying the material and its application such as using for the development of air-powered electric generators, screen displays of smartphones and other electronic devices, improvement of electric cars range and power, and more.
