Summary: This study investigated the characteristics of Se enrichment in the water-soil-plant system, as well as the dietary Se status of local residents in seleniferous areas. The results showed that Se in well water mainly came from Se-enriched shales and coals, and the mobility of Se in seleniferous soils was relatively low. The concentration of Se in edible parts of crops varied widely, with cereal plants having a higher Se-enrichment ability than tuber plants. The probable dietary Se intake in high-Se areas has decreased in recent years but still exceeds the permissible value. Reducing cereal-derived dietary Se intake is an important strategy to improve the Se nutrition status in high-Se areas.

Summary: This study investigates the potential of Pleurotus ostreatus and Pleurotus djamor mushrooms to absorb and accumulate selenium in organic substrate. The results show that Pleurotus djamor grown on Se(IV)-supplemented substrate has the greatest potential for selenium uptake and accumulation. Various selenium species, including selenomethionine, selenocystine, and Se-methylselenocysteine, were identified in the mushrooms. In vitro digestion assays showed high bioaccessibility of selenium. The bioaccessible selenium species were found to be mainly associated with low molecular weight proteins in the mushrooms.

Summary: In this study, we used first-principles calculations to theoretically investigate the electronic properties of monolayer GaSe1-xTex alloys. Substituting Se with Te resulted in changes in the geometric structure, charge distribution, and bandgap. These changes were attributed to complex orbital hybridizations. This study highlights the strong dependence of energy bands, spatial charge density, and projected density of states (PDOS) on the concentration of substituted Te.

Summary: Although the environmental risk of excess selenium in farmlands has been controlled for years, new soil Se-toxicity caused by high-Se water irrigation has been identified in this study. The fixation of input Se by soil organic matter and amorphous iron content plays an important role in increasing available Se in paddy fields. This research warns that attention should be paid to the selection of irrigation water in high-Se geological background areas to avoid new Se contamination.

Summary: In recent years, a new fine-grained task called emotion-cause pair extraction (ECPE) has been proposed in sentiment analysis field, aiming to extract all emotions and their causes from a document. However, existing methods often ignore the relationship between emotion clauses and cause clauses. To address this, we propose an end-to-end framework that uses interactive attention and fusion mechanism to learn the relationship between emotions and causes, achieving better results than state-of-the-art baselines.

Summary: In this study, a drug formulation based on lactic acid bacteria (LAB) was developed to produce reactive oxygen species (ROS) in tumors and induce host immunity. The LAB were modified with zeolitic imidazolate framework-67 (ZIF-67) and effectively delivered into tumor cells, leading to the generation of ROS upon light exposure. The bacterial hybrid induced tumor shrinkage through photodynamic therapy and stimulated inflammation to attract immune cells for cancer elimination.

Summary: In this study, zero-dimensional (0D) monoelemental bismuth (Bi) quantum dots (QDs) were utilized as photocatalysts for direct dehydrogenative phosphonylation under visible light irradiation. The 0D Bi QDs showed high photocatalytic efficiency in the formation of S-P(O) bonds between thiols and H-P(O) compounds. Mechanism study and density functional theory (DFT) calculation revealed the generation of sulfide radicals on the surface of the 0D Bi QDs. The as-synthesized 0D Bi QDs exhibited suitable adsorption energy and sufficient charge transfer to effectively promote phosphonylation. This unique transformation can potentially lead to more sustainable organic photocatalytic transformations based on high-efficiency QDs or QD-related nanocomposites.

Summary: This contribution reports a novel copper-based sponge, polydimethylsiloxane (PDMS)@graphdiyne (GDY)@Cu, which is constructed by in situ synthesis of GDY on a commercial Cu sponge, followed by the modification of PDMS. The as-fabricated PDMS@GDY@Cu sponge not only possesses excellent self-cleaning activity and remarkably enhanced anticorrosion performance, but also displays significantly improved antibacterial activities under irradiation. The results demonstrate that GDY-based functional coatings hold great promises in the protection of copper devices under harsh conditions.
