Physics accidentally cheapen the process of production of graphene Bashny.Net

Scientists from Kansas announced the discovery of a cheap method of production of graphene. The technology is so simple that it consists of three main components: gas, spark plugs and combustion chamber.The approach is as follows: scientists fill the chamber with acetylene or a mixture of oxygen and ethylene. Using the spark plugs from the car the mixture detonates. After the explosion, the graphene is collected on the walls of the aluminum chamber in the form of soot. Therefore, the process of obtaining graphene is the explosion of materials with high carbon content.
 





In this technology no dangerous and harmful chemicals in production. It allows easy scale production under the increasing volume. A particular advantage is that the energy required to start production, is contained in one of the spark plugs.

Method was discovered by accident. Scientists have patented the technology of producing the carbon aerogel. It was the above process of filling the chamber with gas and the explosion. Only after a while scientists discovered that black carbon, drop down after the explosion, graphene. And its mass is measured not in milligrams, as other methods, and visible grams.

Graphene — a sheet of carbon one atom thick — has suddenly become one of the most coveted materials in the world of high technology. Many see it as a panacea for solving problems of medicine and electronics. It is believed that with graphene batteries get high capacity, neural interfaces will become a reality, and doctors will learn to produce unique prosthetic.





The production of graphene is considered to be a difficult and costly process. It's either the exfoliation of the layers, which is done manually in laboratories and can become an industrial solution. Or the use of chemicals, catalysts, and heated to 1000 degrees Celsius, which is energy consuming. Therefore, it is important the advent of cheap methods of obtaining this material.

The relative reduction in price has managed to achieve another team of American scientists. They suggested that the production of graphene-based artificial diamonds. Method reduced the required for the manufacture of temperature and energy. Even more simple solution was able to offer an international group of scientists. Their radical method offers the production of graphene in a normal microwave. published
