Summary: Anisotropic ZrO2 particles with octahedron-, diamond- and plate-like morphologies were successfully synthesized using a hydrothermal treatment approach with NaBF4 as a mineralizer. The concentration of mineralizers played a crucial role in controlling the shape and size of the ZrO2 particles. The introduction of NaBF4 played an essential role in tuning the crystallinity and size of primary ZrO2 nanorods, and the synergistic effect of F- and B3+ resulted in different epitaxial growth rates. The as-prepared ZrO2 particles exhibited different photocatalytic efficiencies for the degradation of organic dyes, with the highest degradation rate of 88% observed for ZrO2 photocatalyst synthesized with a 0.01 mol/L NaBF4 mineralizer under UV irradiation.

Summary: In this study, nonstoichiometric spinel-type cobalt gallate nanoparticles (Co-Ga NPs) were synthesized using the supercritical hydrothermal method with controlled color. The NPs showed high crystallinity and a nonstoichiometric composition. Comparison with calcined CoGa2O4 NPs revealed different cationic configurations and larger polyhedral distortions in the nonstoichiometric Co-Ga NPs. Strategies for achieving a more brilliant blue color were also discussed based on the investigation of the growth process.

Summary: A series of new charge-transfer cocrystals of F(2)TCNQ with anthracene, tetracene, and chrysene were prepared and characterized. The study revealed that face-to-face pi-pi interactions are crucial for the formation of cocrystals, but lateral noncovalent interactions also play a significant role in the supramolecular arrangement and charge transfer. UV/vis spectroscopy and electronic structure quantum chemical calculations classified these cocrystals as small-gap semiconductors with energy gaps of 0.7-1.3 eV.

Summary: The entanglement of charge density wave (CDW), superconductivity, and topologically nontrivial electronic structure has been discovered in the kagome metal AV3Sb5 (A = K, Rb, Cs) family recently. Using high-resolution angle-resolved photoemission spectroscopy, the electronic properties of CDW and superconductivity in CsV3Sb5 are studied. The spectra around K over line exhibit a peak-dip-hump structure associated with two separate branches of dispersion, indicating the isotropic CDW gap opening below EF. The presence of a superconducting gap on both the electron band around Gamma over line and the flat band around K suggests multiband superconductivity. Our results shed light on the controversial origin of the CDW and provide insights into the relationship between CDW and superconductivity.

Summary: Polymorphism refers to the ability of many organic molecules to adopt different crystal structures without changing their chemical structure. It has been found to have an impact on the solid-state properties of organic materials, such as charge transport in organic semiconductors. In this study, a new polymorphic crystal structure of the p-type small molecule semiconductor C10-DNTT is presented. The transition between different crystal structures was observed during heating, and the thin-film crystal structure of both polymorphs was refined using optical microscopy and X-ray scattering measurements. The thermal expansion and anisotropic molecular interactions were further analyzed using density-functional theory calculations.

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.
