A Large Sample Of Glassy Carbon
Carbon is an extremely versatile element. Depending on how the atoms are arranged, it can produce hard diamonds or soft graphite.
XRD patterns of IF-WS2 particles generated from different precursors.

What is graphene?
2-D material
Honeycomb lattice of carbon atoms
Interesting properties
Almost transparent (2.3%)
Stronger than steel
Electrical and thermal conductor
Harder than diamond
Density: 0.77mg/m2
Made of a very common material
Other complex properties...
The formation of the diamond molecule and microscopic properties
Diamond is an allotrope of carbon,
It's in an extremely stable giant covalent lattice . However an other allotrope of carbon is graphite. Its not as hard as diamond as it has a different covalent structure.
Its tetrahydrally bonded which means that it forms a sort of triangle lattice. This almost perfect structure gives the formation below.
Arranged in a honeycomb
lattice in parallel layers
Carbon atom
Van der Waals forces
Strong covalent bonds
Separation of 0.142 nm between the carbon atoms (d)

Distance between planes is 0.335 nm (2.5d)
Carbon Nanotube
Carbon nanotube is an allotropes of carbon with a cylindrical nanostructure. Carbon nanotube is a great conductor of heat and is used in different electronics. Carbon nanotube is part of the fullerine structural family and and is usually in a liquid form or in one atom thick sheets.
