Question

Accepted Answer

4 2 3 1. Kevlar is a high modulus para-aramid synthetic fiber. This fiber is one of the heaviest fibers of all time. Kevlar is a man made fibre developed in 1965 by two research scientists, Stephanie Kwolek and Herbert Blades. Fullerene synthesized in the year 1985, is a series of hollow carbon molecules that form either a closed cage or a cylindrical. Graphene is a single layer (monolayer) of carbon atoms, tightly bound in a hexagonal honeycomb lattice. Graphene is the thinnest compound known to man at one atom thick, the lightest known material, the strongest compound discovered, the best conductor of heat at room temperature and also the best conductor of electricity. It was first synthesized in the lab in the year 2004. Black gold was first synthesized in lab by the scientist of Mumbai based Tata Institute of Fundamental Research (TIFR) in the year 2019. Scientists, used gold nanoparticles and by rearranging size and gaps between them, developed a new material called black gold which has unique properties such as capacity to absorb light and carbon dioxide.
