Summary: Selective cleavage of C-C bond of lignin derivatives and models via oxidation is achieved using P2W17V/{001}-TiO2 heterogenous photocatalysts. The photocatalysts effectively transform lignin model compound to benzaldehyde and phenol, with a selectivity above 85%. This study provides a new approach to selectively break C-C bond in lignin under mild conditions.

Summary: The study evaluates the multicomponent adsorption of pentavalent metalloids, revealing a multilayer, heterogeneous process. Competitive interactions between different metalloids in binary and ternary systems impact the adsorption process, with Sb(V) being the most affected and P(V) the least.

Summary: In this study, the reduction of R-EX2 (E=P, Sb) with two equivalents of KC8 in the presence of silylene (LSiR; L=PhC(NtBu)(2)) has been reported, resulting in the formation of Trip-P=SiL(C6H4PPh2) (1), Ph-Ter-P=(tBu)SiL (2), and Ph-Ter-Sb=(tBu)SiL (3). Compound 3 belongs to a new class of heavier analogues of Schiff bases (>C=N-) and features a formal >Si=Sb- double bond. Theoretical calculations suggest that the pseudo-Si-P/Si-Sb multiple bonds are highly reactive due to the stabilization of lone pairs on the dicoordinated group-15 centers by hyperconjugative interactions, as evidenced by the high first and second proton affinities.

Summary: The thermodynamics of the Sb2Se3 intermediate phase was successfully modeled based on ab-initio calculations and the association model, showing excellent agreement with experimental data. These thermodynamic parameters can be applied in future calculations for high-ordered systems and for determining the thermoelectric properties of Sb2Se3.

Summary: Modified polyoxometalate (POM) derivatives with high specific capacitance properties were successfully synthesized through the traditional hydrothermal method. Among them, compound 1 exhibited a higher specific capacitance value compared to the other three compounds, and the assembled asymmetric supercapacitor showed good cycling stability and excellent energy density, indicating the promising potential of these materials for high-performance pseudocapacitive applications.

Summary: The visible-light-promoted selenocyanation of cyclobutanone oxime esters using potassium selenocyanate in the presence of a fac-Ir(ppy)(3) catalyst is reported for the first time. This method provides an effective and green strategy for the synthesis of cyano and selenocyano bifunctional substituted alkanes, due to the mild conditions employed and the use of readily accessible potassium selenocyanate.

Summary: Sb/Sb2O3 micro-composites can be obtained through a simple electrochemical deposition process, with patterns containing regions rich in Sb and Sb2O3 emerging under specific conditions. The formation of these patterns is proposed to be a result of complex interactions between electrochemical Sb deposition, chemical Sb2O3 precipitation, and convection patterns near the electrode. These findings contribute to a better understanding of electrochemical metal/oxide co-deposition and can aid in the design of advanced composite coatings.

Summary: A simple and effective electrospinning method is used to fabricate Sb/P@C composite nanospheres with adjustable P, Sb ratio and uniform morphology. The improved electrochemical performance of the Sb/P@C anodes can be attributed to the synergistic effect of Na+ ions storage and superior charge transfer in the fabricated composite with reciprocally inlaid Sb/P and C that inhibiting the aggregation of nanospheres. The tactics of this work should be general to other alloy-type systems, indicating great potential for high rate sodium ions anodes.

Summary: The catalytic contribution of PW-containing Keggin polyoxometalates in the conversion of fructose and ethanol into 5-ethoxymethylfurfural (EMF) has been theoretically studied. A proposed mechanism involves proton-induced C-H bond cleavage. The ethanol solvent also plays a significant role in the reaction.

Summary: This study describes the photochemical functionalization of alkoxyoxazoles with trimethylsilyl azide and N,N-dimethylanilines. These C-N bond forming reactions proceed with the assistance of organic dyes as photocatalyst and molecular oxygen, leading to oxidative ring-opening and access to novel chemical space. The unusual demethylative C-N bond formation in the case of N,N-dimethylanilines establishes a new reactivity pattern for these precursors.

Summary: The study found that surface water in the mires of the Changbai Mountains in northeastern China had elevated levels of mercury and antimony, while arsenic, selenium, and bismuth were within permissible limits. The concentrations of antimony were influenced by the acidity of the mire water and were positively linked with arsenic. The inputs of mercury and antimony into the surface water were primarily derived from atmospheric wet deposition and subsequent surface runoff.
