Summary: Crystalline Ni@Ni(OH)(2) (cNNH) and Co-doped cNNH structures were synthesized using a modified chemical reduction method and simple one-pot hydrothermal synthesis. The presence or absence of each reagent was investigated for its effect on the synthesis of the nanostructures. Both nanostructures consisted of a Ni core and Ni(OH)(2) shell layer (approximately 5 nm). Co-doping influenced the morphology and particle agglomeration of cNNH. Co-doped cNNH exhibited higher specific capacitance (1238 F g(-1)) and capacitance retention (76%) compared to cNNH, attributed to reduced path length and increased conductivity due to Co ion substitution. The reported synthesis method and electrochemical behaviors suggest the potential of cNNH and Co-doped cNNH as electrochemically active materials for supercapacitor applications.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

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.
