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
The Atom Station ruining him'. He also struggled to get the novel translated. "Atómstöðin" has been characterised as 'what many readers and critics gradually came to think of as the exemplary Reykjavík novel', focusing on urban Icelandic life for the first time. Laxness dubbed one of his characters, benjamín, an "atómskáld" ('atom-poet'), as a derogatory reference to modernist poets. The name came to be applied to a real group of poets, the Atom Poets. The book was adapted as a film by Þorsteinn Jónsson in 1984. Through the film, the book has been seen to have continued resonances in twenty-first-century Iceland: 'the powerful
