Samsung has published applications, according to a report from the U. In the U. Patent and Trademark Office. Apple, based in Cupertino, California, has at least two patent applications with the office related to the material. Companies from International Business Machines Corp.
Graphene is so thin that when Andre Geim and Konstantin Novoselov from the University of Manchester won the Nobel Prize in Physics in for their work on the material, it was classified as two-dimensional. The material is a single layer of graphite, involving tightly bonded atoms in a hexagonal lattice, making it strong and flexible. Por favor, ten en cuenta qu SINC no es consultorio de salud. Back in , Andre Geim and his colleague Konstantin Novoselov isolated graphene.
This kicked off the development of a new material that, despite not having unveiled all its potential yet, earned them the Nobel prize in Physics in Fifteen years ago, Russian researcher Andre Geim and his colleague Konstantin Novoselov isolated graphene. Extracting a single monolayer of carbon atoms from graphite may have seemed a simple curiosity back then, but many exciting applications were to come.
It was not the first big prize awarded to Geim. He had received an Ig Nobel prize in , a parody of the prestigious Swedish prize given out every autumn to the most unusual scientific achievements. Geim was awarded this honour for using the magnetic properties of water to make a frog levitate.
To date, he is he first an only person to win both awards. Now Geim works at the University of Manchester. SINC spoke to him during a visit to Spain organised by the Graphene Flagship, a long-term European project that brings together more than partners and counts on a 1-billion-euro budget to bring graphene from the laboratory to the market. Why did you start working on this field?
Graphene had never been isolated, nor investigated. It was not understood at all. Furthermore, most people believed that graphene would not even exist if isolated. That is not our goal as scientists. We were trying to figure out what happened to graphite if we kept making it thinner. Isolating graphene kicked off the discovery of a myriad of electronic and mechanical properties that attracted the attention of the community.
We got the Nobel prize for its electronic properties. You enter the world of quantum relativistic physics. Suddenly, we can sit at a table and study phenomena that should only occur at light speed, or in CERN experiments. Nobody thought that would be possible. Also, looking from a wider angle, we had the Stone Age, Bronze, Iron, now silicon and plastics.
All these materials are three-dimensional. There were no 2D materials, where thickness just does not exist. We expanded our toolbox as a species to a whole new dimension, and we are still trying to understand how to use it. That will not happen, in my opinion. A decade ago, there was a lot of hype over the idea that graphene would replace silicon, but developing its applications in electronics will take two or three decades, and now we have dozens of new 2D materials.
Graphene will be used to make faster electronics — at some point one of these materials will replace, or be a great asset to silicon. For instance, some of our partners in Spain already integrate graphene in silicon circuits. There is still too much hype around graphene. Ionic stated that since it published the positive results on its graphene micro planar supercapacitors 2 years before, the company has been working toward developing a device that not only demonstrates similar performance but can be produced at scale to deliver an economically viable device.
