More advances on the holy grail of superconductivity! Unfortunately, at 3.5 Kelvin, this is not exactly room temperature.
"... In 2018, researchers at the Massachusetts Institute of Technology (MIT), Harvard University and the Lawrence Berkeley National Laboratory created the first Kagome metal in the laboratory. The material in that work was an electrically conductive crystal consisting of layers of iron and tin atoms arranged in a Kagome lattice pattern, but the discovery of a whole family of Kagome materials with the chemical formula 𝐴V3 Sb5 (where 𝐴 = K, Rb, Cs) came hot on its heels. ..."
"... We systematically measure the superconducting (SC) and mixed state properties of high-quality CsV3Sb5 single crystals with Tc ~ 3.5 K. ... Our results suggest an intriguing superconducting state emerging in the complex environment of Kagome lattice, which, at least, is partially driven by electron-electron correlation."
