Summary: Potassium-ion batteries (KIBs) are considered as an alternative to lithium-ion batteries due to the abundance and low cost of potassium. However, the volume change during the insertion and extraction of large-sized potassium ions leads to structural collapse and irreversible charging/discharging process. In this study, a nanoengineered material, MoSe2/NP-HCNS, was synthesized through thermal annealing and heteroatom doping strategies. This material has a cleverly designed hierarchical nanostructure that can accommodate volume change, enhance electrolyte penetration, and prevent aggregation of MoSe2 nanosheets. The MoSe2/NP-HCNS anode exhibits high reversible capacity and long cycling life, making it a promising anode material for KIBs.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.
