In an extraordinary new development that could change the future of the military and law enforcement, scientistis have just figured out a way to create a lightweight material that is bulletproof. Scientists combined two graphene layers and created a new material that is both soft and light, and also can become as hard as a diamond if a bullet or some other object makes contact with it.

This material, known as diamene, was developed by scientists at City University of New York’s Advanced Science Research Center. They combined two pieces of graphene at room temperature, and the result is a material that is as thin as aluminum foil. However, once scientists put it under pressure, it became hard and rigid.

The findings, published in the journal Nature Nanotechnology, began as a computer simulation but later transitioned to the real world, as they combined the layers and then subjected them to pressure from an atomic force microscope. The result was a material with “diamond-like properties.”

“Imagine a material as flexible and lightweight as foil that becomes stiff and hard enough to stop a bullet on impact,” reads a statement from the research center. “In a newly published paper in Nature Nanotechnology, researchers across The City University of New York (CUNY) describe a process for creating diamene: flexible, layered sheets of graphene that temporarily become harder than diamond and impenetrable upon impact.”
