Experiments have been conducted on the use of graphene oxide (GO) being added to concrete to improve both compressive and tensile strength. However the hydrophilic and high resistivity nature of GO limits its applications in things such as ‘smart’ cement. Due to the high aspect ratio of nano-reinforcements such as graphene and carbon nanotubes, they have the ability to arrest crack propagation in concrete (by controlling the nano-sized cracks before they form micro-sized cracks) and hence greatly improve peak toughness, making them more effective than even conventional steel bar or fibre reinforcements.
The media tends to depict bullet-proof armor as something that’s thick and heavier than regular clothes. Despite being for bodily protection, the added bulk of that armor might restrict a person’s movements. But scientists at the City University of New York’s Advanced Science Research Center (ASRC) have found that diamond-hard armor doesn’t need to be thick. The key to less-bulky protection is graphene, a tightly-packed layer of bonded carbon atoms one million times thinner than a piece of paper.
