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 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: 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: 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: This study investigates the interaction between biologically produced sulfur and selenium oxyanions during the bio-reduction process. The results show that the addition of biologically produced sulfur and sulfate promotes the bio-reduction of selenium oxyanions and accelerates the formation of hexagonal selenium. Hexagonal selenium is advantageous for separation and recovery and has lower mobility and toxicity compared to amorphous selenium.

Summary: Researching carbon dioxide removal from flue gas and natural gas is crucial. Metal-organic frameworks (MOFs) are commonly used in adsorption due to their high surface area, porosity, and chemical properties. An ultra-microporous MOF CPM-20(Co) with mixed ligand was synthesized using inexpensive ligands. The material exhibited high selectivities and low regenerative energy, making it a promising option for CO2 separation in industries.
