Arsenic heats up iron superconductors
High-temperature materials set scientific community a-buzzing.
A new class of high-temperature superconductors has been discovered in a breakthrough that once again has the scientific community whispering that economically feasible magnetic levitation and lossless energy transmission may be possible.
First discovered in 1911, superconductors can conduct electricity with virtually no resistance and can maintain a current without a voltage being applied.
