Graphene smaller amplitude and higher frequency. This phenomenon, named "membrane effect", was predicted by Lifshitz in 1952. A prediction that was published in 2015 suggested a melting point of ≈4125 K. Recent and more sophisticated modelling has increased this temperature to at least 5000 K. At 6000 K (the sun's surface having an effective temperature of 5,777 K) graphene melts into an agglomeration of loosely coupled doubled bonded chains, before becoming a gas. The carbon–carbon bond length in graphene is about 0.142 nanometers. Graphene sheets stack to form graphite with an interplanar spacing of . Graphene is the strongest material ever
A Boy and His Atom in a companion video about the film's production, "you could carry around every movie ever produced." A Boy and His Atom A Boy and His Atom is a 2013 stop-motion animated short film released on YouTube by IBM Research. The movie tells the story of a boy and a wayward atom who meet and become friends. It depicts a boy playing with an atom that takes various forms. One minute in length, it was made by moving carbon monoxide molecules with a scanning tunneling microscope, a device that magnifies them 100 million times. These two-atom molecules were moved to create
