Summary: This study presents a self-healing triboelectric nanogenerator (TENG) fabricated using self-healing polyimide (PI) for energy harvesting and motion sensing. The PI-based TENGs exhibited excellent intrinsic self-healing properties, attributed to dynamic disulfide bond exchange and flexible PDMS fragments in the PI backbone. The output performance of the TENG was significantly improved due to CF3 electron-absorbing groups and siloxane fragments in the PI backbone. Practical applications of self-healing PI-based TENGs, including energy harvesting for commercial electronic devices and joint motion sensing, were demonstrated.

Summary: Heterostructured compounds with engineered interfaces have been widely studied as efficient electrocatalysts for oxygen evolution reaction (OER). However, the mechanism behind their intrinsic activities remains unclear. In this study, a NiSe2/FeSe2 heterostructure catalyst was fabricated through the selenization of Ni-Fe Prussian-blue analog templates, showing low overpotential (230 mV at 10 mA cm(-2)) and long-term durability. In-situ/operando Raman spectroscopy and synchrotron-based X-ray absorption spectroscopy (XAS) were used to investigate the catalytic process, revealing that the surface reconstruction into Ni-O-Fe configurations and the presence of high-valence NiIII-O-FeIII moieties in Ni-FeOOH are responsible for the high oxygen evolution activity. Density functional theory (DFT) simulations further confirmed that electron transfer driven by strong Ni-Fe synergistic effect in the NiSe2/FeSe2 heterostructure not only enhances the density of Ni/Fe active sites but also modulates their nature. This work provides insights into the intrinsic activities of metal compound heterostructures and the relationship between dynamic surface structural evolution and catalytic activity.
