Properties of Graphene.
The properties of graphene are multiple and very varied. But this material stands out especially for:

A high thermal and electrical conductivity (superconductor).
Its flexibility and reduced weight.
It is a very resistant material (up to 200 times superior to steel).
It presents biocompatibility with living organisms.
Able to react chemically with other substances to form compounds with different properties.
Chemically stable at room temperature.
Supports ionizing radiation.
Low environmental impact
All these properties make graphene a material with many uses in various fields of application such as aerospace technology, medicine, electronics and the environment.

Nature of Carbon: Graphite and Diamond

Pure Carbon is found only in nature, forming the structure of the minerals of graphite and diamond. Its different structure (the skeleton that forms the mineral) conditions its physical properties. Thus, the more packed cubic structure presented by the diamond compared with that of graphite makes the former have higher thermal and electrical conductivity properties or hardness.

From Coal to Graphene, new opportunities for coal mining?
In 2004, scientists at the University of Manchester isolated, from graphite, carbon atoms with the thickness of a monolayer. Carbon is part of the fundamental unit of graphene, a sub-millimeter section of mineral graphite, which is common in the earth's crust. In addition, it is present in many other minerals, such as coal, one of the main banners of coal mining. The technical capacity to transform the remains derived from coal, through new technological advances, opens up a range of future possibilities for our mining for the production of graphene. Thanks to its properties, this material has allowed the development of new technologies, lighter, with lower consumption and higher benefits. Nowadays, it is present in numerous fields such as electronics, medicine, security, aerospace technology or even as a fundamental part in the production of clean and renewable energy.

Usefulness of graphene

Take a look around you and you will realize that you are surrounded by things with graphene, from computers, cars, phones and stereo equipment to airplanes.

That's right, because of its properties, both aircraft and space satellites or automobiles have graphene as a material in their composition, making them safer. Also in the construction of buildings, it would make them more resistant.

Surely where you have most heard this material is in the field of electronics, where through its ability to store energy can provide the batteries a longer duration and a shorter loading time, establish faster connections and even contribute to improve the environment replacing polluting materials that we are forced to use today.

Let's not forget its importance in health. In the near future graphene prostheses could replace the current or even could be applied to improve the treatment of some diseases.
