graphene
GRAF-een
/ˈɡræfiːn/
A single layer of carbon atoms arranged in a two-dimensional honeycomb lattice.
Known for being the thinnest, strongest material in existence and an excellent conductor.
The story behind the word. Coined in 1962 by combining 'graphite' with the suffix '-ene' (used for certain carbon molecules). It remained a theoretical material until it was actually isolated in 2004 using simple adhesive tape.
Commonly confused with
- graphite: Graphite is made of many layers of graphene stacked together.
Collocations
- graphene sheet
- layer of graphene
- graphene oxide
Example sentences
- "Graphene is the thinnest material in the universe and the strongest ever measured." Nobel Prize press release for the discovery of graphene. (The Nobel Prize in Physics 2010)
- "Graphene-based electrodes could allow smartphones to charge in seconds rather than hours." A discussion on future battery technology.
Memory hook
Think of 'Graphene' as a 'Graph' (drawing) that is 'Thin' and 'Green' (environmentally friendly). One-atom-thick carbon.
When not to use
Do not confuse with 'graphite' (the bulk material in pencils) or 'graphic' (related to images).
Fun facts
- If you had a hammock made of graphene, it would be virtually invisible but could support a sleeping cat.
