Explanation:
Aerographene, also known as graphene aerogel, is believed to be the world’s lightest material with a density of just 0.16 milligram per cubic centimeter. Zhejiang University researchers developed the material, which is approximately 7.5 times less dense than air. The extremely elastic material can absorb up to 900 times their own weight in oil and water, making oil spill cleanups a potential application.
