Origin of electrochemical activity in nano-Li2MnO3; Stabilization via a 'point defect scaffold' [PDF]

, 2015
Molecular dynamics (MD) simulations of the charging of Li2MnO3 reveal that the reason nanocrystalline-Li2MnO3 is electrochemically active, in contrast to the parent bulk-Li2MnO3, is because in the nanomaterial the tunnels, in which the Li ions reside ...

Aluminosilicate-Supported Catalysts for the Synthesis of Cyclic Carbonates by Reaction of CO₂ with the Corresponding Epoxides

Molecules, 2022
Functionalized aluminosilicate materials were studied as catalysts for the conversion of different cyclic carbonates to the corresponding epoxides by the addition of CO2. Aluminum was incorporated in the mesostructured SBA-15 silica network.
