ScienceWrinkled graphite may host tiny superconducting regions above room temperature
A post describing the research says the material trapped magnetic flux at ambient pressure up to around 117°C, possibly higher—a potential sign of superconductivity.
TLDR
According to a post describing the research, graphite was ground into thin nanoflakes, and some samples were heated in air to create dense networks of wrinkles. The wrinkled samples reportedly trapped magnetic flux after an external field was removed; non-wrinkled samples showed almost no comparable trapping. The post says the researchers think strained regions could create tiny superconducting “islands.” A separate comment cautions that the claimed effect is local, not bulk, and that past graphite superconductivity claims have been hard to replicate widely.
