Molecular computer graphic showing the crystal structure of one of the new generation of high- temperature superconductors - yttrium-barium- copper oxide (Y-Ba2-Cu3-O7-x). Discovered in 1987, the new superconducting ceramic materials are expected to lead to a technological revolution, & are the subject of intensive worldwide research. The two Swiss researchers who discovered these new superconducting materials were awarded the 1987 Nobel Prize for physics.
