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.

3. 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.

4. 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.

5. 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.

6. 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.

7. 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.

8. USES
• Engineering: (main construction materials)
concrete
coating
steel

9. Specific Properties
(GOALS)
o Manipulate atoms individually.
o Placement of atoms in pattern to produce desired structure.

10. SMART TEXTILES
Irene Pérez

11. 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.

12. 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.

13. 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

14. 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

15. CARBON NANOTUBE AND
NANO FLAKES

16. 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

17. 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.

18. 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.

19. 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.

21. NANOFLAKES

22. 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.

23. • 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.

24. 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
