WebHace 1 día · Many physicists regarded the claim warily because 6 months earlier, Nature had retracted a separate room-temperature superconductivity claim from Dias’s group, amid allegations of data manipulation. Now come accusations that Dias plagiarized much of his Ph.D. thesis, completed in 2013 at Washington State University (WSU). Figure 3A shows normalized magnetization for a bulk polycrystalline hexagonal ε-NbN as a function of temperature below 20 K under a magnetic field of 3 mT (or 30 Oe). Clearly, the magnetic susceptibility measurements reveal obvious diamagnetic responses at temperatures of ∼11.6 K and ∼17.5 K, respectively. … Ver más Polycrystalline hexagonal ε-NbN bulk specimens used for the current magnetization and electrical resistivity measurements were … Ver más Niobium nitride polymorphs are attractive also due to their excellent mechanical/elastic properties (elastic behavior) besides … Ver más
