Oxygen and chlorine generation without precious metals: Electrode potential changes the MXene surface
Credit: Journal of the American Chemical Society (2024). DOI: 10.1021/jacs.4c08518 MXene is a type of two-dimensional material discovered in 2011. Previous theoretical studies predicted that MXene has no catalytic activity in anodic processes. Researchers led by Professor Kai S. Exner, head of the Department of Theoretical Catalysis and Electrochemistry at the University of Duisburg-Essen (UDE), used multiscale modeling to disprove…

Can precious metals become superconductors?
Predicted dependence of the superconducting critical temperature of ultrathin gold films as a function of film thickness. As the film thickness decreases, the temperature at which gold becomes superconducting can be measured experimentally and matches the temperature of well-known superconducting elements such as aluminum. Credit: A. Zaccone and G. Ummarino Superconductivity is a phenomenon in which current flows through metals…
