The latest British research and development of new carbon-based superconducting materials

Researchers at the University of Liverpool and Durham University found that by applying some pressure to change the crystal structure of C60, Cs3C60 under different C60 crystal structures can be transformed from magnetic insulator to superconductor, and its superconducting conversion temperature also changed from 38K to 35K. The researchers said the new findings will help reduce the cost of energy storage applications such as magnetic resonance imaging scanners and other superconductors. In an article in the latest issue of Nature, the researchers pointed out that they used splinter neutron sources (ISIS) and synchrotron radiation sources (Diamonds) from the Rutherford Appleton Laboratory in the United Kingdom and European synchrotron radiation The facilities proved successful that the molecular structure of Cs, Cs, and Buckyball (a natural molecule of carbon atoms, also known as C60, which has a molecular structure similar to that of a dome designed by Buckminster Fuller, ) Cs3C60, a new material made up of non-conductive materials, is not itself conductive, but it becomes a high-temperature superconductor when squeezed. The pressure exerted on the object causes the C60 to contract and transform from a body-centered cubic structure to a face-centered cubic crystal structure while overcoming the repulsive forces between the electrons so that the electrons can "double-pair" and pass without resistance substance. The study, part of a research project funded by the Engineering and Natural Sciences Research Council, seeks to investigate what methods can be used to create superconductors that operate at higher temperatures to reduce costs while keeping these materials at the most suitable temperature , A wider range of applications. The researchers said that C60 and the role of alkali metal to form AxC60 (A on behalf of potassium, rubidium, cesium, etc.), they are superconductors. The advantage of a carbon-based superconducting substance is that different carbon structures have different characteristics and therefore, the substances produced have different functions and attributes. The flexibility of carbon-based superconducting structures allows scientists to better understand the mechanics of HTS production and learn how to make higher-temperature superconductors, carbon-based HTS, or the future of the mainstream. Matthew Rossecki, a professor of inorganic chemistry at the University of Liverpool, said it was the first time people have demonstrated that controlling the behavior of molecules in a high-temperature superconductor can control their properties, as C60 does. Comas Mas Prades, a professor of chemistry at the University of Durham in the UK, said the new study is important for the development of HTS because it allows people to see when the superconductivity breaks through the insulation and "explodes" , Regardless of the specific structure of the atom, which is impossible for any previous substance. From the 1911 Dutch Anis accidentally discovered the sudden disappearance of mercury resistance began to superconducting next year completely accompany humanity 100 years. Looking back, the "centenarians" have had lonely melancholy, but also had gorgeous brilliant. Especially in 1987 wave critical temperature "step by step" superconducting heat waves, has been talked about. Taking off heavy cotton gowns seems to have been the constant expectation of the old man because it would be a new technological revolution that would have as much significance as semiconductor materials. The latest discoveries of new carbon-based superconducting materials are welcome, but we are even more desperate for a theoretical breakthrough in HTS to get rid of the stalemate in the field.
