This document discusses several topics related to nanotechnology: - Carbon nanotubes are hexagonal networks of carbon that are just nanometers in size and have extraordinary mechanical and thermal properties. They were first discovered in 1991 and have applications in electronics. - Smart textiles are fabrics that can function electrically through embedded computing and digital components. They originated in the 1990s for military use and now have applications in healthcare like monitoring vital signs. - Nanoflakes are a new material discovered by Martin Aagesen that form a perfect crystalline structure allowing absorption of all light, making them promising for highly efficient solar cells. Their use could significantly reduce the cost of solar energy production.

NANOTECHNOLOGY Elena Martín
Description WHAT IS NANOTHECNOLOGY? • It is the engineering of functional systems at the molecular scale. • It is an hybrid science combining engineering, chemistry and also biology. • Generally atoms and molecules stick together and have complementary shapes; millions of these atoms are pieced by nanomachines at a certain shapes for specific profucts.
Origins • Richard Feynman described a process by which the ability to manipulate individual atoms and molecules might be developed. • The emergence of nanotechnology in the 1980s was caused by: • The convergence of experimental advances such as the invention of the scanning tunneling microscope in 1981. • The discovery of fullerenes in 1985.
Uses • It can be used in mecidine, engineering, etc. Medicine: The application of nanotechnology in the field of health care has come under great attention in recent times. There are many treatments today that take a lot of time and are also very expensive. Using nanotechnology, quicker and much cheaper treatments can be developed.
Uses • It can be used in mecidine, engineering, etc. Military service: the science of designing microscopic structures in which the materials and their relations are machined and controlled atom-by-atom, holds the promise of numerous applications.
Uses • It can be used in mecidine, engineering, etc. Engineering: Nanotechnology is related to the development of materials since at this scale materials present different properties from the classical microscopic materials and their properties as we know them.
USES • Engineering: (main construction materials) concrete coating steel
Specific Properties (GOALS) o Manipulate atoms individually. o Placement of atoms in pattern to produce desired structure.
SMART TEXTILES Irene Pérez
SMART TEXTILES o They’re fabrics that can function electrically as electronics and behave physically as textiles which enable computing, digital components and electronics to be embedded in them.
HISTORY AND ORIGINS o Early 1990s: MIT students started research on smart clothing for military use. o 1998: Beginning of the integration between fashion and technology. o 2001‐present: Started to integrate medical uses into clothing.
SPECIFIC PROPERTIES o E-textiles a new emerging inter disciplinary field of research, bringing together specialists in information technology, microsystems , materials, and textiles. o Properties: -Flexible -No wires to snag environment. -Large surface area for sensing. -Invisible to others. -Cheap manufacturing
USES o E-textiles can be used: -To sense tank movements -To monitor homes fornoxious chemicals -Help firefighters maneuver in smoky buildings, and perhaps help stroke victims recover their function -For sensor network communications -Physical therapy -They can also be used in a smart home to detect the movement of people and adjust the lighting or sound systems
CARBON NANOTUBE AND NANO FLAKES ALICIA COSTA FRESNEDA
CARBON NANOTUBE Carbon’s compound material, with extraordinary electronic properties, thermal, structural and attractive mechanical for futures aplications in field like: • transmision line nano-escale or nano • antennas or nano • Actives and passives components: NEMS
CARBON NANOTUBE • In chemistry, nanotubes is denominated a tubular structure which diametre is nanometro order (nm). 1 nm = 1x10-9 m • Carbon Nanotubes are a alotrpic form of carbon. • Depend in the grade of the roll and the way that approve the original sheet, they could have diferents diametre and internal geometric.
CARBON NANOTUBE • Carbon nanotube are form of hexagonal net of carbon, bend and closed, which form tubes of carbon of nanometre size. • The individual tubes have very small diameters (typically ~ 1nm), and are curled and looped rather than straight. • It present an extraordinary mechanic and termal property, their fisrt aplication was made in electronics.
ORIGIN • The molecules were first discovered by S. Lijima in 1991, when he was studying the synthesis of fullerenes by using electric arc discharge technique. • The high resolution transmission electron microscopy was employed for observation of that phenomenon.

NANOFLAKES Elena Martín Irene Pérez Alicia Costa
SPECIFIC PROPERTIES • If future solar cells from the researcher Martin Aagesen work correctly, our economy and environment will be benefied. • He believes that nanoflakes have the potencial to transform at least 30% of solar energy into electricity for our daily use.
• It was discovered by Martin Aagesen, he discovered a perfect crystalline structure. That is a very rare sight. While being a perfect crystalline structure we could see that it also absorbed all light. It could become the perfect solar cell. • Its discovery has sparked a lot of attention internationally and has led to an article in Nature Nanotechnology.
USES • We can reduce the money we spend on producing solar cells because (thanks to the nanotechnology) we use less silicon semiconductor in the progress. • The potential is unmistakeable. We can reduce the solar cell production costs because we use less of the expensive semiconducting silicium in the process due to the use of nanotechnology. At the same time, the future solar cells will exploit the solar energy better as the distance of energy transportation in the solar cell will be shorter and thus lessen the loss of energy
