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: The regioselective synthesis of novel functionalized condensed organochalcogen compounds was achieved through chalcogenocyclofunctionalization reactions based on chalcogen halides and natural products thymol and carvacrol. Various selenides, sulfides, telluranes, and ditellurides were successfully synthesized with high yields, highlighting the distinct reactivity of sulfur, selenium, and tellurium halides in the reactions.

Summary: Nanocrystals of Si doped with S, Se and Te were synthesized at high temperatures and their structure, morphology, and optical and electrical properties were studied. The presence of sulfur and selenium resulted in recrystallization of Si and the formation of crystalline rods with unique cross-sections, while samples doped with sulfur and selenium showed high conductivity.

Summary: The experimental structural features of over 34,000 linear fragments involving chalcogen bonding (ChB) interactions were analyzed. The role of the chalcogen, the covalently bonded atoms, and the chalcogen bond acceptor were highlighted. An innovative approach for the evaluation and categorization of ChB strength based on structural data was proposed.

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: 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: This work proposes a Fe(II)/Fe(III) redox mediated SO2 conversion method for simultaneous hydrogen production and sulfur dioxide capture at low voltage. Experiments show that SO2 in the electrolyte can reduce Fe(III) to Fe(II), completing the Fe(II)/Fe(III) redox cycle and the conversion of SO2 to sulfuric acid. The assembled flow cell electrolyzer exhibits good performance under low voltage.

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: A series of Fe-2(mu-SR)(2)(CO)(6) complexes with different substituents have been synthesized, and the products and isomers were obtained using different synthetic methods. It was found that adding phosphine ligands can generate adducts with different coordination numbers, and the formation of products is also influenced by the light conditions. The properties of these complexes were studied through structural characterization and electrochemical testing.

Summary: The sticking coefficients of selenium and tellurium were measured as a function of temperature, with both sharply dropping within a narrow temperature range. While the sticking coefficient of tellurium reached zero at high temperatures, selenium's coefficient remained around 0.2 even at elevated temperatures.

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: Incorporating [2Fe-2S] catalyst into PDMAEMA-g-[2Fe-2S] metallopolymers and adsorbing them to the electrode surface increases the rate of hydrogen production. Molecular dynamics modeling shows that the high performance is a result of the natural assembly of these metallopolymers on the surface, bringing the [2Fe-2S] catalytic sites in close contact with the electrode and maintaining exposure to protons in solution. These results provide guidance for enhancing the performance of other electrocatalysts by incorporating them into polymers that optimize their interaction with the electrode and solution.
