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
Just Between the Two of Us Just Between the Two of Us Just Between the Two of Us is a duet album by country singers Merle Haggard and Bonnie Owens and The Strangers released in 1966 on Capitol Records. At the time of Haggard's first top-ten hit "(My Friends Are Gonna Be) Strangers" in 1965, Owens was actually the better known performer, a fixture on the Bakersfield club scene who had recorded and appeared on television. Bonnie, who had been married to Buck Owens, won the new Academy of Country Music's first ever award for Female Vocalist after her 1965 debut album, "Don't Take Advantage of
