Summary: This paper reports on a new class of high entropy disordered rocksalt oxides (HE DRXs) based on the Ni2+-Nb5+ pair, and investigates the structural and chemical evolution of DRXs with increasing transition metal species. The study proposes an explanation for the existence of HE DRX in single rocksalt solid solution structures based on the crystal field stability energy, and reveals the charge compensation mechanism in HE DRX as a result of various transition metal synergistic effects. The effective integration of more transition metal cation species within the HE DRX framework promotes better Li+ diffusion and improves lattice oxygen stability, leading to increased capacity upon cycling.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
