Before revision: Electron micrograph of a linear carbon chain (carbyne) between a carbon lump and Fe electrode This polymeric carbyne is of considerable interest to nanotechnology as its Young's modulus is – forty times that of diamond; this extraordinary number is, however, based on a novel definition of cross-sectional area that does not correspond to the space occupied by the structure.
