means A single, honeycomb-patterned layer of carbon atoms just one atom thick — the thinnest material physically possible, yet one of the strongest and most conductive ever measured.

from From 'graphite' (the soft carbon in your pencil, itself from Greek 'graphein,' to write) plus the chemistry suffix '-ene,' used for carbon-based molecules with specific bonding patterns — the same ending found in 'benzene' or 'ethylene.' Graphite is just stacked layers of this stuff, flaking off onto paper a sheet at a time whenever you write. The breakthrough was isolating a single one of those sheets, which researchers in the 2000s famously managed using nothing fancier than sticky tape, peeling graphite thinner and thinner until only one atomic layer remained — work that won a Nobel Prize.
