👉 The Shanghai Fluid, also known as the Shanghai Superconducting Fluid (SSF), is a high-temperature superconducting material that operates at temperatures between 35 and 55 Kelvin (-238 to -220°C), significantly higher than conventional superconductors. It is a liquid mixture of hydrogen sulfide (H₂S) and a small amount of deuterium oxide (HDO), which is used to enhance its superconducting properties. When cooled below its critical temperature, the Shanghai Fluid exhibits zero electrical resistance and perfect diamagnetism, allowing it to carry electric current without energy loss. This unique state makes it highly efficient for applications such as magnetic levitation (maglev) trains, where it can generate strong magnetic fields with minimal energy consumption, and in advanced scientific instruments like particle accelerators and MRI machines.
