Summary: In this study, novel high-purity basic magnesium sulfate whiskers were successfully prepared under low-temperature and atmospheric-pressure conditions using a sodium citrate admixture. The whisker products were characterized in terms of their structure and morphology, and it was found that they could be further converted into high-purity MgO whiskers with smooth surfaces. These findings provide technical support for the cost-effective industrial-scale preparation of basic magnesium sulfate whiskers and related whisker products.

Summary: We report on di- and trinuclear palladium sandwich complexes of cross-pi-conjugated fulvenes. Structural and theoretical analysis demonstrated that the fulvene sandwich framework possesses a metal-metal bonded moiety, with strong donation and back-donation observed in the dinuclear and trinuclear bonds, respectively. The trinuclear fulvene sandwich complex exhibits a unique reversible extrusion of a Pd atom from inside to outside the sandwich framework.

Summary: In this research, a modified castor oil-based epoxy is synthesized and waste expanded polystyrene (EPS) is used as a filler in the improved biocomposite. The properties of the biocomposite are evaluated using response surface methodology and artificial neural networks. Chemical characterization and physical analysis of the biocomposite are performed. The results show that the use of modified castor oil increases the activation energy and reduces the petrochemical content in the biocomposite. The incorporation of waste EPS reduces production cost and density, while increasing thermal insulation and workability. A new model equation is developed to study the thermal decomposition behavior.

Summary: The recent discovery of metal-metal bonding in dilanthanide complexes has opened up possibilities for accessing molecules with novel bonding motifs and magnetism. Trinuclear mixed-valence clusters have been synthesized via reduction of trivalent clusters, and their valence delocalization has been supported by various analyses. The high-spin ground state and large spin-spin exchange constant observed in these clusters highlight the significance of metal-metal bonding in lanthanide compounds.

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.

Summary: In this work, two metal organic frameworks (MOFs) containing {Cu2I2} clusters, Eu-CuI-INA and Sr-K-CuI-INA, were synthesized and characterized. Both materials have a three-dimensional structure with {Cu2I2} clusters coordinated by INA(-) ligands and Eu3+ or Sr2+ ions. The Sr-K-CuI-INA material exhibited sensitive fluorescence sensing behaviors towards cysteine and nitro-bearing molecules, showing potential applications in bio and explosive molecule sensing. This work provides a good reference for designing fluorescent MOF probes containing CuI molecules.

Summary: Na-ion batteries (NIBs) have attracted great interest as a potential technology for grid-scale energy storage due to the wide distribution, low cost, and environmental friendliness of sodium resources. However, their implementation is hindered by low rate capability and cycling stability caused by the large ionic size of Na+. In this study, a three-dimensional nanoarchitectured coral-like CoSe2@N-doped carbon (CL-CoSe2@NC) was synthesized, and it exhibited improved sodium storage properties with better electrode kinetics and a stable SEI film.
