As per the latest reports, scientists have successfully managed to develop a unique bulletproof graphene sheet that can actually save millions of lives across the world. A team of scientists at Advanced Science Research Centre at the City University of New York made this special bulletproof graphene suit material.
They claim that on impact from any fast-moving or heavy object, this graphene material becomes harder than diamond. That means when a bullet touches the bullet-proof graphene suit the suit becomes a hard diamond plate and absorbs all the impact. The scientists have named this very very thin material as diamene.
This diamene is thinner than Aluminum foil and transforms immediately on impact. The material can block even the fastest and the most powerful bullets and hence can effectively save many lives.
Lead researcher Elisa Riedo, professor of physics at the ASRC said that this is the thinnest film with the stiffness and the hardness of diamond ever created. “Previously, when we tested graphite or a single atomic layer of graphene, we would apply pressure and feel a very soft film. But when the graphite film was exactly two-layers thick, all of a sudden we realized that the material under pressure was becoming extremely hard and as stiff, or stiffer, than bulk diamond,” explained Riedo.
After deeply analyzing electric properties of diamene in the lab, scientists found out that during the conversion of the material, a sudden reduction in electric current traveling through the material is observed. From this, the scientists got to know that the diamene material could exhibit unique electronic and spintronic properties.
The scientist ran computer simulated models and observed the outcomes when two honeycomb layered sheets of graphene are subjected to immediate and high pressure. The scientists found out that the graphite-diamond switch occurs if two graphene layers are combined. It does not undergo transition if just a single layer is used or more than two graphene layers are used.
Angelo Bongiorno, associate professor of chemistry at CUNY College of Staten Island who was a part of the research said that Graphite and diamonds are both made completely of carbon, but the atoms are arranged differently in each material, giving them distinct properties like hardness, flexibility, and electrical conduction. Our new technique allows us to manipulate graphite so that it can take on the beneficial properties of a diamond under specific conditions,” he said.
