Summary: In this study, sterically invariant carborane-based chalcogenols were used as ligands for the formation of photoluminescent copper(I)-based metal-organic chalcogenolate assemblies (MO-CHAs). By precisely tuning the carborane dipole through isomer changes, control over MOCHA morphology and regulation of photophysical properties were achieved. Additionally, microcrystal electron diffraction (MicroED) was shown to be a powerful tool for elucidating metal chalcogenide structures, revealing a novel Cu4Se4 geometry in one isolated material.

Summary: A doping strategy is implemented in Ketjenblack sulfur cathodes by introducing selenium to enhance charge transfer and sulfur utilization. The S-Se composite cathodes exhibit better performance compared to bare sulfur cathodes, with improved efficiency and higher capacity. The use of these cathodes also enables a more uniform anode reaction and longer cyclability by suppressing polysulfide dissolution.

Summary: Chalcogens, especially sulfur and selenium, have diverse applications from pharmaceuticals to energy storage. This study introduces a new methodology for controlling the morphology of chalcogen nanostructures by leveraging the interaction between metal oxides and polysulfides/polyselenides. Different metal oxide substrates induce the formation of various multidimensional chalcogen morphologies, which are applied as cathodes in Li-chalcogen batteries with demonstrated structure-performance correlation. This metal oxide-mediated control of chalcogen morphology is a general strategy that can be applied to advance chalcogen-based applications in other fields.

Summary: The assembly of supertetrahedral chalcogenolate clusters (SCCs) and multifunctional organic linkers allows for the formation of tunable structures and synergistic properties. Two SCC-based assembled materials (SCCAM-1 and-2) were successfully synthesized and characterized using a triangular chromophore ligand, tris(4-pyridylphenyl)amine. The SCCAMs exhibit unusually long-lived afterglow at low temperatures (83 K) and demonstrate efficient activities for the photocatalytic degradation of organic dye in water.

Summary: This paper reports a new oxidative fluorination reagent consisting of an SF5- anion and a chemically inert phosphonium cation, which is thermally stable. Using this reagent, the SeF5- and TeF5- anions were successfully generated and tetrafluoro(phenyl)-lambda(5)-selenate and -tellurate were synthesized. Furthermore, further derivatization of the tetrafluoro(phenyl)-lambda(5)-tellurate allowed the introduction of functional groups into organic molecules.

Summary: In this study, a VN modified porous carbon nanofiber film was designed as a host for loading SeS2 as the cathode material, leading to enhanced Li storage capacity. The conductive porous carbon nanofibers were able to accommodate active SeS2 and accommodate the volume changes. Introducing VN nanoparticles effectively anchored the intermediate species and improved the utilization of SeS2. As a result, the SeS2@VN/CNFs cathode exhibited superior electrochemical performance and good long-term cycling stability in Li-SeS2 batteries.

Summary: Using high-resolution X-ray crystallography, the study visualized tRNA-dependent conformational changes in human SepSecS and showed that tRNA(Sec) binding organizes the active sites of the catalytic protomer. The study also demonstrated that productive SepSecS·tRNA(Sec) complex formation is driven by electrostatic interactions between tRNA(Sec) and SepSecS. This research provides a structural basis for understanding the terminal reaction of Sec formation.

Summary: The research found that selenite in simulated slurry can be reduced by SO2 to form amorphous elemental selenium, while selenate remains unaffected. Increasing SO2 concentration in flue gas accelerates the reduction of selenite, and the reduction reaction is exothermic. Additionally, the oxidation effect of S2O82- competes with the reduction effect of SO2.

Summary: Doped carbon materials, especially F-doped carbon catalysts, have gained significant attention as metal-free catalysts for oxygen reduction reactions and as corrosion-resistant supports for Pt and non-Pt nanoparticles. F-doped carbon materials possess unique properties and greatly improve the activity and durability of the ORR compared to N-doped carbon materials. The high electronegativity of F-doping can efficiently modify the electronic band structure of carbon materials, favoring the ORR. This review systematically discusses the effect of F-doping/F co-doping on the electrocatalytic reduction of O2 in acidic and alkaline conditions, the stability and durability of fuel cell catalysts, and provides guidelines for working with F-doped carbons. Future research directions on F-doped carbons are also proposed to bridge the gap between laboratory-scale assessments and commercial applications.
