New materials were always the bearer of new technologies and subsequent social development. Let’s go back in the history and think of the Stone Age, which became the Bronze Age and then the Iron. Every material or technology was greater than its predecessor and made life easier.

There is also a material called Graphene, which has grown significantly in the last ten years and believed to change the future of mankind.

Overview

The wonderful material was discovered in 2004 at the University of Manchester by Dr. Konstantin Novoselov and Professor Andre Geim. They examined the efficiency of the graphite as a transistor.

The easiest way to describe graphene is to imagine it to be the thinnest material. Only one thick atom! This means that this material is 2-dimensional mathematically. And this layer of atoms in your hands can still be held!

Graphene is not surprisingly unusual or uncommon. It has the same structure as the graphite, which is used in your daily work in a pencil for drawing or writing. But 0.03 inches of Graphite = 3 million Graphene Layers.

(Graphite is an allotrope of the carbon element, which means that it has the same atoms but is organized differently and gives different properties to the material.)

Graphene was used to be unbelievably costly to produce. It took a huge cost of 1,100 dollars to create sufficient graphene to cover a pinhead. But 0,35 oz of graphene could be purchased at $1,000 until the end of 2015. It is believed that over the coming years the price will be reduced as much as the graphite itself.

Graphene ‘s unbelievably long. It can extend up to 25% of its length! This material, too, is very rigid. It’s the hardest material people know of — even more difficult than diamonds.

Graphene stands out from all other materials by one unique property. It expands while it’s cooling and shrinks when the temperature is hot, while other materials are reversed.

Both researchers were awarded the Nobel Prize in physics in 2010, for their contributions in the field of graphene.

 

Uses of Graphene

Drinking water from the ocean

The ultimate solution to many countries ‘ water crises can be graphene. Graphene can be used for the production of membranes so thin that it can be used to remove the content of salt from the ocean water as a filter.

Health care

Scientists have found that graphene could be used to detect cancer cells in the body.

Graphene can be used as temporary tattoos. These tattoos are more than just decorations of the body, but can instead be used to track people’s vitals, hydration and skin temperature.

Recharging gadgets

Batteries based on graphene can recharge at unbelievable speed. It will be able to hold the charge for a long time and also the battery will slowly degrade compared with normal lithium-based batteries.

Flexible smartphone displays

If today’s smartphone companies use graphene to create their displays, we end up with a flexible display. As mentioned above, its flexibility is one of the features of graphene. So graphene-based electronics will have the same characteristics.

Many applications of graphene are hard to explain in one post. The above is the most important of them.

Making of Graphene

Graphene can be produced by many methods. The steps of preparation of graphene at home are as follows:

  1. Put a thick layer of graphite on a paper using a lead pencil.
  2. Use the usual sticky strip then to peel the graphite layer off the paper.
  3. To remove a layer of graphite from the first sticky tape, use another piece of sticky tape.
  4. Then use the third piece of unused adhesive tape to remove a layer from the other piece of adhesive tape and so on…
  5. Finally, the graphite layers are diluted and diluted, and you will end up with a small portion of graphene.
  6. Even if it works like that, it takes time and patience.

World Today

The fact is, of course, that it takes years to develop any new technology. It is unreasonable to expect graphene to transform life overnight.

A lot of research is taking place on graphene. The idea is that it will be that which will change the coming years of our world, and because of its unique properties it will also be useful for spatial exploration.

Whether graphene is present or not, it does not matter. The people understand that the products should be much better than the products they use now.
