2. CONDUCTIVE DEAFNESS
• Conductive hearing loss is when an individual loses their
hearing so they only hear muffled sounds. This is a result of a
problem with the ear canal, ear drum or the middle ear along
with small bones located in the ear such as, the malleus, stapes
and incus.

3. CAUSES OF CONDUCTIVE HEARING LOSS
• Malformation of outer ear, ear canal, or middle ear structures
• Otitis media - an infection of the middle ear in which an
accumulation of fluid may interfere with the movement of the
eardrum and ossicles
• Allergies
• Benign tumors
• Infection in the ear canal
• Etc.
4. HISTORY ON NANOTUBES
• The first invention of the multiwalled nanotube was in 1991 by a Sumio
Iijima.
• Iijima also created the first visual impression of this breakthrough.
• Many people think that this discovery wasn’t taken seriously at the time
because the scientific community didn’t know how much this could impact
scientific research.
• In 1993, Iijima and Donald Bethune invented single walled nanotubes, which
then made it easier for the scientific community to see more potential for
nanotubes
• In 2005, A breakthrough for solar panels was uncovered after a carbon
nanotube diode was developed that had photovoltaic properties, making
solar panels more efficient.
5. WHAT IS IT MADE OF? WHAT DOES IT LOOK
LIKE?
• Carbon nanotubes are made of carbon formed in a hollow
cylindrical shape. The diameter on these tubes are on the
nanoscopic level. One nanometer is equal to one billionth of a
meter. The size of these tubes are ten thousand times smaller
than human hair. The bonding between the carbon atoms that
make up the tubes are extremely strong, allowing the tube to
be manipulated in multiple different ways. Carbon nanotubes
can be multi walled or single walled. Carbon nanotubes are also
stronger than steel.

6. CONCEPT OF CURING CONDUCTIVE
DEAFNESS
• Although at this time it is not a solid cure, it is in the horizon.
Carbon nanotubes have some of the same properties at certain
bones in the ear, they can pass vibrations much similar to the
way the incus pass vibrations. It is still in concept, but they are
developing Nano sensors that will be able to pick up the
vibrations given off by the tube and then turn it into electrical
impulse to trigger a response in the hearing nerve
7. HOW ELSE CAN IT BE USED?
• Carbon nanotubes have multiple different applications. Some
other applications are as follows:
• Electronics: Carbon nanotubes are conductive material, they can be used
for transistors. They can also be used in electrical cables and wires, for
speakers and multiple other electronics.
• Solar cells: Carbon nanotube diodes have highly efficient photovoltaic
properties.
• Environment: Carbon nanotubes can be used for water treatment.
8. COST?
ACCORDING TO SCIENCE DAILY IN 2012, THE PRICE OF CARBON NANOTUBES IN THE US
WAS $15 - $35 PER GRAM.
9. RECENT EVENTS
• MIT discovers that water inside carbon nanotubes remain solid
at boiling temperatures.

10. CONCLUSION
IN A WORLD WHERE TECH IS GETTING SMALLER AND I-PHONES ARE GETTING BIGGER,
NANOTECHNOLOGY IS ON THE RISE. WE NEED TO START INVESTING MORE TIME AND
EFFORT INTO THIS CATEGORY. WITH MORE RESEARCH WE CAN ACCOMPLISH AND
OVERCOME GREAT BARRIERS.
