A group of scientists led by Artem Oganov of Skoltech and the Moscow Institute of Physics and Technology, and Ivan Troyan of the Institute of Crystallography of RAS has succeeded in synthesizing thorium decahydride (ThH10), a new superconducting material with the very high critical temperature of 161 kelvins. A truly remarkable property of quantum materials, superconductivity is the complete loss of electrical resistance under quite specific, and sometimes very harsh, conditions. Despite the tremendous potential for quantum computers and high-sensitivity detectors, the application of superconductors is hindered by the fact that their valuable properties typically manifest themselves at very low temperatures or extremely high pressures.Until recently, the list of superconductors was to...

Cobalt-based alloys have been used in demanding applications for as long as investment casting has been available as an industrial process. Arcam’s Electron Beam Melting technology competes directly with investment casting and is a viable choice for manufacturing complex parts in cobalt-based alloys. The majority of investment castings made from the cobalt super alloys are cast in an open atmosphere. With Arcam’s Electron Beam Melting process the vacuum atmosphere provides a controlled environment and enables superior material properties in the manufactured parts. CoCrMo alloys are widely used for medical prosthetic implant devices. The alloys are especially used where high stiffness or a highly polished and extremely wear-resistant material is required. CoCrMo alloys are the materials of choice for applications such as knee implants, metal-to-metal hip joints and dental prosthetics.
