Defect Generation and Evolution in Irradiated Epitaxial Films and Heterostructures of Fe3O4 and Cr2O3

open access: yesAdvanced Materials Interfaces, EarlyView.
The functionality of nuclear structural materials, sensors, and microelectronics in radiation environments relies on understanding defect generation and evolution processes in oxide layers. The initial radiation response of Fe3O4 epitaxial thin films is characterized by the formation of large vacancy clusters, but these defects do not lead to lattice ...

Structural Insights Into Aluminum‐Doped Manganese Dioxides as Promising Materials for Direct Lithium Extraction: Modeling and Mechanism Study

open access: yesAdvanced Materials Interfaces, EarlyView.
A two‐stage sorption mechanism is proposed for Al‐doped HMnO in direct lithium extraction. Batch sorption experiments and modeling identify two key sorption sites on Al‐HMnO: surface sites (planar and edge) and vacancy sites (W). At pH 12, Stage I involves surface ion exchange, followed by Stage II, where surface complexation occurs between Li⁺ ions ...
