Atomic‐Scale Visualization of Topotactic Resistive Switching in Epitaxial La0.5Sr0.5CoOx Neuromorphic Memristors

Advanced Functional Materials, EarlyView.
Forming‐free epitaxial Pt/La0.5Sr0.5CoOx (LSCO)/La0.5Sr0.5MnO3 (LSMO) memristors exhibit heterogeneous and partially reversible topotactic switching involving brownmillerite (BM)‐, Grenier (GN)‐like‐, and perovskite (PV)‐like configurations. Atomic‐resolution scanning transmission electron microscopy and in situ transmission electron microscopy resolve

Effective separation of coal gasification fine slag: Role of classification and ultrasonication in enhancing flotation

International Journal of Mining Science and Technology
Effective separation of residual carbon and ash is the basis for the resource utilization of coal gasification fine slag (CGFS). The conventional flotation process of CGFS has the bottlenecks of low carbon recovery and high collector dosage.
