What is graphene? What is it used for? The most amazing thing about this
semi-metal of the future is the fact that you can produce it yourself in your
living room!
What is graphene, and why is it so amazing? One of the things that makes
graphene so cool is that it’s the thinnest material you can imagine. It's just
one atom thick! This means this material is mathematically 2-dimensional. And
you can still hold this single layer of atoms in your hands!
Surprisingly, graphene isn't a unique or rare substance. In fact, it has
the same carbon structure as the graphite you use every day when you draw or
write with your pencil! But at the same time, in 0.03” of graphite, there are
about 3 million graphene layers!

SUMMARY:
- Graphene isn't a unique or rare substance. In fact, it has the same
carbon structure as the graphite you use every day when you draw or write with
your pencil! But at the same time, in 0.03” of graphite, there are about 3
million graphene layers!
- Dr. Konstantin Novoselov and Professor Andre Geim discovered the
wonder-material in 2004 at the University of Manchester. They were examining
how efficient graphite is as a transistor. The story goes that graphene
appeared thanks to sticky tape!
- Graphene used to be incredibly expensive to manufacture. It cost a
whopping $1,100 to produce enough graphene to cover the head of a pin. However,
by the end of 2015, you could buy 0.35 oz of graphene for $1,000.
- Graphene is incredibly stretchy. It can stretch as much as 25% of its
length! This material is also really stiff. Actually, it’s the hardest material
people know about — even harder than diamonds, and that says a lot!
- One more great thing about graphene is its relationship with
electricity. This material carries electricity more quickly, more precisely,
and more efficiently than any other known material.
- Graphene may be the answer to the water crisis many countries are
facing. If we make membranes from graphene, they would be able to let water
through while filtering out salt at the same time.
- One layer of graphene is impressive enough. Can you imagine what you
could achieve with 2 layers of this super material? Nothing short of incredibly
strong body armor.
- If producers start to use graphene in gadget manufacturing, we might
end up with smartphones that can be bent in any direction. One of graphene’s
main properties is its flexibility.
- Graphene can be used in the beauty industry as well. It will be the
perfect alternative to current hair dyes, most of which are still toxic and
damaging to hair.
- Well, you can potentially make graphene at home, provided you have
enough time and patience to do so.

TRAVEL : TIBET
HIMALAYAN MAN WITH THE MOST
EXPENSIVE DOG IN THE WORLD:
HOW IS THEIR DAILY LIFE?

Hello fellows,
Tashi Delek! This is Jamyang.
Today, I will take you to get a close look at the Tibetan Mastiff, a
large breed of dog that can be found on the Tibetan Plateau, and now all around
the world.
In Tibetan, the dogs are known as Drog-Khyi, which means "nomad
dog", or "dog which may be tied/kept”.
The Tibetan Mastiff has been the loyal herd dog of the nomadic Tibetan
herdsmen for thousands of years, protecting the herds and flocks from attacked
by predators such as wolves, leopards, bears, and tigers.
A full grown male dog can reach up to 33 inches in height, and can weigh
between 45-70 kilograms.
In Tibet, there exists a strong bond between the nomads and their hugely
protective dogs.
As pups, the dogs live together with the family, and as time passes a
friendship takes root between the mastiff and the family members.
Friendship and alliance is automatically understood by the mastiffs, as
part of their natural instincts, and the bond that is forged between the dog
and its family is unbreakable.
While they are primarily a working dog, bred specifically to protect the
herds and the family, Tibetan nomads take extremely good care of the animals,
and they are well fed and well looked after by their families.
I would like to share with you the story of Tibetan Mastiff, Dolma and
its owner nearby Yamdrok Lake, and see how are their daily life.
Hope you will enjoy my video as usual.

Ever wonder how we actually
know that atoms exist? Here we'll learn what atoms are and exactly how
scientists went about figuring all this out.

Note about the Nitrogen atom
Image:
The nitrogen paper was
supposed to be published along with this animation but the journal decided the
nitrogen paper was too redundant. They already published the same imaging
technique with an Ag atom back in 2017. Long stroy short: The only place to see
the nitrogen atom is in this animation. That said, if you want to see an Ag
atom imaged using the same technique, see this paper here: https://pubs.acs.org/doi/10.1021/acsn...
Each pixel in the image
represents a reading from the scanning probe. The colors show us how high that
particular part of the atom's electron cloud is compared to the substrate it's
sitting on. Red is highest, blue is lowest. We are only seeing the outline of
the electron cloud, not the nucleus.

Correction: In this video I
state that Jabir ibn Hayyan was Arabian, but there is uncertainty about this
among historians. He may have been Persian. Like many influential people of his
time, his story is almost mythical, with multiple origins being found in
historical writings.
Also, he never used a Bunsen
burner (which is what I drew him using) that wasn't invented until 1856. Jabir
likely burnt wood or other solid fuels to heat his reactions.
