Some interesting preprints with a shared theme:
Probable cause for the superconductor-like properties of alkane-wetted graphite and single-layer graphene above room temperature under ambient pressure
Superconductivity above 500 K in conductors made by bringing n-alkane into contact with graphite
Observation of the Meissner effect at room temperature in single-layer graphene brought into contact with alkanes
Quantum effects in graphitic materials: Colossal magnetoresistance, Andreev reflections, Little-Parks effect, ferromagnetism, and granular superconductivity
Phonon hydrodynamics and ultrahigh-room-temperature thermal conductivity in thin graphite
Superconductivity in Hydrogenated Graphites
Electric-field induced strange metal states and possible high-temperature superconductivity in hydrogenated graphitic fibers
Now, Pablo Esquinazi and his colleagues at the University of Leipzig report that flakes of humble graphite soaked in water seem to continue superconducting at temperatures of greater than 100 ?°C
