Description
Summary:Copper has long been a contender for the highly sought trait of room-temperature superconductivity - the ability of some materials to conduct electricity with zero resistance - so many physicists argue that nickel-based materials might be the next-best place to look. The first 'high-temperature' superconductor was reported in 1986 in a material that was later identified to be of the form Еа2_хВахСиО4 (La, lanthanum; Ba, barium; Cu, copper; 0, oxygen; x can range from around 0.05 to 0.12), and showed superconductivity below 30 kelvin (ref. 3). [...]as any superconductivity specialist would probably tell you in confidence, publishing a paper in Nature is something of a double-edged sword - it is an accolade, but also welcomes extra scrutiny.
