Granular superconductivity in powders of small graphite grains (several tens of micrometers) is demonstrated after treatment with pure water. The temperature, magnetic field and time dependence of the magnetic moment of the treated graphite powder provides evidence for the existence of superconducting vortices with some similarities to high-temperature granular superconducting oxides but even at temperatures above 300 K. Room temperature superconductivity in doped graphite or at its interfaces appears to be possible.
经过纯水处理后，小石墨颗粒（几十微米）的粉末中表现出了颗粒超导性。处理后的石墨粉末的磁矩的温度、磁场和时间依赖性为存在超导涡旋提供了证据，这些超导涡旋与高温颗粒超导氧化物有一些相似之处，但即使在 300K 以上的温度下也是如此。在掺杂石墨或其界面中实现室温超导似乎是可能的。
