Researchers from the National Institute of Standards and Technology (NIST) has discovered a new type of iron-based superconductor that shares the same magnetic properties with the older copper-oxide superconductors. The amazing fact is that the new superconductors have all those magnetic properties at higher temperatures.

The AISI 2007 Environmental Briefing presented the North American steel industry’s efforts to increase energy-efficiency of steel production and products, including a new steelmaking technology that completely avoids the emission of greenhouse gases.
