What is graphene, graphene properties and applications

Graphene is considered by many as the material of the future but the truth is that this super-material is already a reality.The properties of graphene make this substance unique and that its applications present and future seem to be taken from a science fiction book. There are fields of study, technologies and products that, due to their disruptive nature, have the potential to change the world forever.For example, nanotechnology, artificial intelligence or graphene can generate revolutions similar to those promoted by industrial robots, internet or plastic. As a great enthusiast of science and technology I have been following the track to this material for several years and in this article I want Share with you the answer to the most fascinating questions about this material. What is graphene? What is graphite? In broad strokes we could say that graphene is a very thin layer of pure carbon whose atoms are hexagonally linked together following a honeycomb pattern The dist...
