Summary: Ionic liquids (ILs), including task-specific ILs, have the ability to dissolve various solids at moderate temperatures without special reaction vessels. This study investigated the synthesis of sulfides of various elements in ILs as well as the dissolution of antimony sulfide in ILs. Additionally, a new quadruple heterocubane cation was discovered through the crystallization of Sb2S3 in a Lewis-acidic IL.

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: The reaction of chalcogen dioxides with As2O3 in a high-temperature hydroflux solution resulted in the formation of potassium trichalcogenides crystals with dimensions up to 2 cm. The new heterochalcogenide anion was formed during the process. The reduced activity of water played a key role in the unexpected redox reaction and precipitation of hygroscopic compounds.

Summary: Germanium, indium gallium arsenide, indium antimonide, and mercury cadmium telluride dominate as short-wavelength infrared photo-sensing materials. However, their complex fabrication process and high production cost limit their widespread applications. Recent studies have shown that TexSe1-x has great potential for infrared photodetection, but the current devices suffer from high dark current and poor performance. In this work, high-quality TexSe1-x films were fabricated using thermal evaporation and low-temperature annealing, and the optoelectronic properties were systematically investigated and optimized. The resulting photodiodes based on the optimized TexSe1-x thin films exhibited high responsivity, reduced dark and noise current density, and a fast response time. Prototypical devices based on Te0.65Se0.35 thin films were successfully demonstrated for optical communications, showing the potential for low-cost short-wavelength infrared photodetection.

Summary: In this research, different hybrid nanostructures were synthesized by annealing Ti3C2Tx with pre-selected group VI chalcogen elements. Among them, the Te/Ti3C2Tx supercapacitor showed the highest specific capacitance (150.6 F/g), as well as good cycling stability and energy density. These improvements were attributed to the formation of TiO2 and the large polarizability of the Te element.

Summary: In this study, a universal method for synthesizing nanoradiosensitizers with well-controlled structure and multifunctionality is developed to address the challenges of cancer radiotherapy. Dumbbell-shaped TeSe nano-heterojunctions exhibit better radio-sensitizing activities and can degrade to highly toxic metabolites in acidic environment, depleting GSH within tumor to facilitate radiotherapy. Furthermore, the combination of TeSe nano-heterojunctions with radiotherapy reshapes the immunosuppressive microenvironment and induces robust T lymphocytes-mediated antitumor immunity, resulting in great abscopal effects on combating distant tumor progression. This study provides a universal method for preparing nanoradiosensitizers and overcoming the clinical challenges of cancer radiotherapy.

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.

Summary: Developing low-cost and self-supported bifunctional catalysts is crucial for highly efficient water splitting devices. In this study, nano-NiFe2O4 was directly grown onto iron foil surface and Sn4+ was introduced into the NiFe2O4. The resulting Sn-NiFe2O4/IF showed low overpotentials and high current densities during oxygen evolution reaction (OER) and hydrogen evolution reaction (HER), making it a promising catalyst for large-scale hydrogen production.
