Summary: A facile approach of introducing ultrasound for the large-scale rapid synthesis of core-shell C@MnO2 nanoparticles was suggested. The mesoporous C@MnO2 particles possess a high specific surface area of 62.8 m(2) g(-1). The stable gel electrolyte enabled the C@MnO2 electrode to deliver a specific capacitance of 177 F g(-1) at 0.5 A g(-1) under a high mass loading and a specific capacitance of 128 F g(-1) at 10 A g(-1) current density. Long-term test confirmed the practical application of MnO2 for energy storage devices, with only an 8.3% decline in initial capacitance after 5000 cycles.

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.
