SILICON AND GRAPHENE Juan Laorden Martinez Enrique J. Vervoort
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.
ORIGEN & HISTORY • Known for 500 years. • Andre Geim, profesor. • Related to Graphene • Konstantin Novoselov, student. Founders, Nobel prize winners
SPECIFIC PROPERTIES • Density: 2,33 (g/cm3) • Colour: Metalic Grey. • Fusion point (ºC): 1414. • Boiling point (ºC): 2680. • Atomic Volume (cm3/mol): 12,06.
USES • Chips. • Solar Photovoltaic Cells. • Water Treatment Systems. • Nano Technology. • Telecommunications • Catalyst.
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
ORIGINS AND HISTORY -Andre Geim and Konstantin Novoselov
SPECIFIC PROPERTIES • High thermal, electrical conductivity • High elasticity, high hardness. • High resistance. 200 times stronger than steel. • Similar resistance as a diamond, lighter. • Graphene is practically a transparent material.
USES • Blindage • Informatics • Electronics • Vehicles
