21 Απρ 2017 · Corpus ID: 31445401. Janus Monolayer Transition-Metal Dichalcogenides. Jing Zhang, S. Jia, +8 authors. J. Lou. Published in ACS Nano 21 April 2017. Materials Science, Physics, Chemistry. TLDR.
22 Αυγ 2017 · Abstract. The crystal configuration of sandwiched S-Mo-Se structure (Janus SMoSe) at the monolayer limit has been synthesized and carefully characterized in this work. By controlled sulfurization of monolayer MoSe 2, the top layer of selenium atoms is substituted by sulfur atoms, while the bottom selenium layer remains intact.
18 Μαρ 2020 · The development of separate levers for controlling the bonding strength of different reactive species on catalyst surfaces is challenging but essential for the design of highly active and selective catalysts.
Abstract: A simple modeling method to extend first-principles electronic structure calculations to finite temperatures is presented. The method is applicable to crystalline solids exhibiting complex thermal disorder and employs quasi-harmonic models to represent the vibrational and magnetic free energy contributions.

7 Μαΐ 2020 · The present study sheds light on deeper understanding of atomic-scale local configuration in TMDs and a methodology to boost the intrinsic activity of chalcogen atoms. Designing and realizing ...
29 Ιαν 2021 · Abstract. Synergistic effects have been discussed extensively in bimetallic heterogeneous catalysis, but it remains unclear how the effects function at the atomic scale. Here, we report a dual single-atom catalyst (DSAC) Ir 1 Mo 1 /TiO 2 displaying much greater catalytic chemoselectivity (>96%, at 100% conversion) than comparable single-atom ...
