A new glass ceramic material could become a better alternative to use in construction. Miguel Hernández University (UMH) professor Manuel Jordán has contributed to the creation of a new glass ceramic material from sludge contaminated with toxic chromium. This new material has high resistance to bending compared to others of the same class, and once processed, is nontoxic and environmentally harmless.The new glass ceramic material is 75 percent composed of sludge with high levels of hexavalent chromium Cr (VI), a toxic form of chromium that comes from industrial processes such as the manufacturing of stainless steel or curing leather. This chemical substance is highly soluble and its consumption has been linked to risks of cancer and allergies. The researchers ...

Scientists have calculated that a hydrogen-rich compound could conduct electricity without resistance at temperatures up to about 200° Celsius — well above the 100° C boiling point of water. If that prediction is confirmed experimentally, the material would stand in stark contrast to all other known superconductors, which must be cooled below room temperature to work.
