Filters capable of separating the gas mixture at the molecular level were obtained from graphene. Folded like origami, graphene becomes a semiconductor. Transformed according to the Kagome network principle, graphene demonstrates the properties of a superconductor.
Since childhood, we have been accustomed to the fact that when you add one apple to another, you get two apples. The same thing happens with pencils, typewriters and balloons. And in physics, this is not necessarily the case. If two films of monatomic thickness, like graphene, are brought together at a sufficiently small distance, then a new material will be obtained.
In 2016, scientists from Cornell University (USA) for the first time managed to develop a technology for folding graphene sheets.
