PROPERTIES
The lightest material known. The best conductor of heat at room
temperature . The strongest compound discovered. Best conductor of electricity known. Graphene could well be an ecologically
friendly.gra Stiff.
USES Improvement the performance and
efficiency
current materials and substances NAND flash memory. Replace silicone in electrical systems in the
future. Bioengineering, composite materials,
energy technology and nanotechnology.
Optical Engineering: Touchscreens. liquid crystal displays (LCD). organic light emitting diodes (OLEDs).
Biological Electronics It could be utilised in the process of tissue regeneration.
Ultrafiltration. Water filtration and desalination systems and biofuel creation.
Composite Materials.
Photovoltaic Cells. Alternative to silicon in the manufacture of photovoltaic cells.

CARBONE NANOTUBES
INDEX DESCRIPTION.
ORIGIN AND HISTORY.
PROPERTIES.
USES SPACE ELEVATOR
DESCRIPTION
Tubular or cylindrical carbon structures measured in nm.
Structure : single layer and multiple layer. It’s a alotropic shape of carbon. Nanoshaped hexagonal units.
ORIGIN AND HISTORY In 1991 the resercher Sumio Lijima (Japan)
descovered them. He found fibres deposited in a soot’s speck. Due to its shape they were called Carbone
Nanotubes. Some years later there were created one
layer nanotubes.
PROPERTIES
Elasticity. Thermal conductivity. It’s one of the most hard material known. Mechanic resistance. Chemically motionless and biologically
compatible. They can be insulators and conductors.
USES
Solar cells and storage of hydrogen. Automobile ligh pieces or space vehicles. Transistors. Rechargeables batteries, automobile pieces,
sport articles, etc. Lithium’s ion batteries. To administer therapeutic heat, drugs and
medical sensors to attack carcinogenic cells.
Disciplines that study its applications.
Space elevator NASA’s scientifics project. It would be made of carbon nanotubes. Due to its properties. Through this elevator spacial ships would go
into the space. Economic improvement in spacial missions. http://www.youtube.com/watch?v=cxIUAE

NANOFLAKES
INDEX
Description. Background. History. Properties. Uses.
DESCRIPTION Perfect crystalline structure. Very rare sight. The perfect solar cell. Unmistakeable potential. Silicon combine with others
semiconductor materials.
BACKGROUNDIn 1946 Russell Ohl-Solar cells: Made up → silicon
• Good properties
• Very expensive
Applications of nanotechnology in solar cells – Organic solar cells
HISTORY
Nano-Science Center. University of Copenhagen. Martin Aagesen. During his work on his PhD thesis. SunFlake Inc. 2007.
PROPERTIES
Absorbs all light. Thanks to nanotechnology it uses less
silicon → cheaper. Silicon → semiconductor.
USES Transform 30% of sunlight into energy. Transformer of sunlight into electricity at
home. → Thanks to low cost.
