Two-Dimensional Rare Earth -- Gold Intermetallic Compounds on Au(111) by Surface Alloying [PDF]
The Journal of Physical Chemistry Letters 2020, 2020 Surface alloying is a straightforward route to control and modify the structure and electronic properties of surfaces. Here, We present a systematical study on the structural and electronic properties of three novel rare earth-based intermetallic compounds, namely ReAu2 (Re = Tb, Ho, and Er), on Au(111) via directly depositing rare-earth metals onto ...

Crystal chemical simulation of superconductors on the basis of oxide and intermetallic layers [PDF]
Supercond. Sci. Technol. 21 (2008) 095019, 2008 Simulation of 'hybrid' superconductors of 3d-, 4d- and 5d-transition elements consisting of two different superconducting fragments located between positively charged ions planes - B'O2 oxide planes and B2C2 intermetallic layers - has been performed on the basis of the structure of Sr2Mn3As2O2 (A2(B2C2)(B'O2)).

High-throughput calculations combining machine learning to investigate the corrosion properties of binary Mg alloys [PDF]
arXiv, 2022 Magnesium (Mg) alloys have shown great prospects as both structural and biomedical materials, while poor corrosion resistance limits their further application. In this work, to avoid the time-consuming and laborious experiment trial, a high-throughput computational strategy based on first-principles calculations is designed for screening corrosion ...

Reduction of Na+ within a {Mg2Na2} Assembly
Angewandte Chemie International Edition, Volume 62, Issue 3, January 16, 2023., 2023 Treatment of a low oxidation state {Mg2Na2} assembly with basic molecules that are less prone to reduction than the sodium cation itself induces the complete extrusion of the elemental alkali metal. Abstract Ionic compounds containing sodium cations are notable for their stability and resistance to redox reactivity unless highly reducing electrical ...
