SILICON
• its a chemical element with the symbol ¨Si¨.
• 14 atomic mass.• Also named Polycyclic Aromatic
Hydrocarbon.• Strong, brightly, prone to chipping.• Flexible, Transperent, Self-cooling.• Light-weighted, Elastic, Thermal
Conductivity.• Cristal red, honeycomb form.

GRAPHENE
-Its a laminate flat estructure
-It Consists of pure carbon atoms arranged in a regular hexagonal pattern similar to graphite
-It is very light, a sheet of 1 square meter weighs just 0.77 milligrams
