• Resumen

  • The article discusses high-temperature superconductivity and the discovery of compounds known as iron pnictides that can produce temperatures exceeding absolute zero. Conventional superconductors use copper oxide or cuprate as a coolant, but their use has been difficult to adapt to industrial applications. Topics include a brief overview of cuprates, how the study of pnictides has enabled scientists to understand how cuprates work, which could result in the creation of a room-temperature superconductor, and an in-depth examination of the importance of temperature in superconductivity. Japanese scientist Hideo Hosono and colleagues doping research, the quanta of sound, and a brief overview of BCS theory of superconductivity is presented.
