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.
