Grafeno: Características y Aplicaciones | El material del futuro

From a fortuitous event, was discovered a material that can revolutionize
the future of humanity.
If you didn't know graphene, I promise you will not forget it.
Graphene is a material that comes from graphite the same used in
the pencil mines.
And like most discoveries, graphene was found almost by accident.
It turns out that to obtain the most pure graphite, the researchers used to attach
a zeal tape and pluck,
until one day one of them decided to analyze the remains in this film
and seeing he realized that there was a new material
composed of carbon and hydrogene atoms sorted like a beehive
making it have some impressive features.
High thermal and electrical conductivity.
High flexibility
and hardness.
Graphene is two hundred times harder than steel and even harder than
diamond.
Resistance:
Graphene is the strongest material in the world.
Very light: as the carbon fiber but more flexible.
It's transparent.
Lower Joule effect:
heating less when driving electrons.
Thanks to its amazing features, are being discovered
some of its uses and functionality,
although it's clear that some new will appear in the future.
Shortly, processors will be much faster than current ones.
Today, processors tend to lose energy as heath,
but thanks to graphene features we could exploit this
to improve their performance,
and not heating up they don't lower their performance with the passing hours.
To give you an idea: silicon processors today
can achieve a power of 40 gigahertz while if we replace
the silicon with graphene, they could even reach the thousand
gigahertz of power, no more and no less than 25 times more potent.
With graphene could also be created flexible and
transparent displays.
These well be composed on one hand by a light OLED technology layer
that would show the image, and on the other by a sheet of graphene
that would protect this layer and be responsible for recognizing our
tactile cues. So …
Would it be possible to manufacturate a augmented reality lens?
Furthermore, graphene could help develop a new type of batteries
that would increase tenfold their capacity and charge rate with respect to the
current batteries.
That way, our devices autonomy will
be considerably increased.
Currently conventional cameras capture images using a sensor
responsible for converting incoming light into a digital signal.
Now, thanks to the sensibility of graphene,
we could get sensors capable of capturing an image with better quality
in low light conditions.
Besides, the graphene sensors would consume ten times less energy and
would be five times cheaper.
At last decent night photos!
It was also discovered that graphene may carry information
hundred times faster than current fiber optic,
this way it would revolutionize world of telecommunications.
Solar panels:
A very modern technology like these could become obsolete with the advent
of graphene,
and is that these material is capable of absorbing energy from the sun
and transform it into useful energy,
and all at a much lower weight. Can you imagine all the walls of
the graphene coated buildings?
In the field of medicine, graphene could be used to
improve cancer treatments.
Today the current treatment is to remove cells
of the affected area,
both bad and good.
But with the help of graphene could be eliminated only
the bad cells and therefore less aggressive treatment is achieved.
On the other hand in the field of biotechnology
could be made implants to replace damaged tissues.
Since one of the graphene characteristics is it's high electricity conductivity
it would be the perfect candidate to replace
damaged circuits. So they could make retinal implants
to return sight to patients who have lost it
and if all that don't seemed enough yet
we have left last one of its best features:
It turns out that researchers at the Manchester University
have seen that graphene can auto repair itself.
Come on, Superman
will be obsolete next to Graphene-Man. This is due to it
carbon and hydrogen atoms composition, which can be found in the air,
and is that when suffering a small tear graphene alone will seek the
atoms required in his environment. Undoubtedly when we speak of
graphene, we talk about one of the most revolutionary materials,
that can change the future with its amazing features
and uses.
Anyway there are many features that are still
to be found out,
and you can discover them little by little in our website.

Until Next Video!
