In nature, pure carbon is most often found in the form of graphite. This soft black material has unique physical properties – fire resistance (up to 1500 ° C), the highest electrical and thermal conductivity among non-metals, refractoriness, chemical resistance, plasticity, high specific heat capacity, etc. Graphite […]
Read more →Even 20 years ago (at the beginning of the XXI century), three-dimensional (diamond, graphite), one-dimensional (nanotubes) and zero-dimensional (fullerenes) allotropic forms of carbon were known. Scientists assumed the presence of a 2D modification, but could not detect it due to the thermodynamic instability of two-dimensional crystals. For […]
