Developed a new type of magnet consisting of three layers of graphene
The Tata Institute of fundamental research has detected the presence of magnetism of the electrons in the three layers of graphene. A new kind of magnets will allow to create electronic devices based on graphene for fundamental research and home use.Metals have a high electron density, and to consider the wave nature of electrons, it is necessary to use a metal wire a few atoms wide. The thickness of the graphene does not exceed the atom and the electron density it has less, so it can be changed by using the transistor.

Usually, metals such as copper, the electrons are scattered in every 100 nanometers. The scattering caused by imperfections and content of various impurities. In graphene the electrons more space to move — they can cross up to 10 micrometers. It is enough to position the graphene between layers of boron nitride. Boron nitride also has imperfections, but their number is negligible and they do not affect the flow of electrons in graphene.
As soon as the electrons start to pass a longer distance, and the number of imperfections is reduced, there is a distinctive sound. The electrons begin to "whisper". The process allows one to observe the electron interaction in three layers of graphene at a temperature of -272 degrees C. during observations of the Indian scientists not only discovered a new kind of magnet, but also to better understand how to use the electronic devices based on graphene for fundamental research and other fields.

Graphene can be used to manufacture microelectronics, biomedical devices, sensors and solar panels. First, however, engineers need to reduce the cost and simplify the process of its production. So Kansas scientists have discovered a cheap way to produce graphene using gas, spark plugs and combustion chamber. A team of researchers from the State Association scientific and applied research Australia (CSIRO) has developed a cheap graphene-based material is soy. published
