Malignant neoplasms consistently pose a significant threat to global public health [1,2]. In recent years, immunotherapy has demonstrated remarkable clinical success; however, its efficacy is limited by the scarcity of immune cell infiltration within tumor microenvironments. Cell pyroptosis, a gasdermin-mediated process characterized by cellular swelling,rupture, and the release of intracellular contents such as IL-1β, IL-18, ATP, HMGB1, plays a crucial role in this context[3,4].

Ultrastrong room-temperature phosphorescence in cucurbit[8]uril-mediated crystalline supramolecules for ratiometric detection of phenethylamine

Science China Chemistry 2025年

作者： Qingyu Niu Yingxiang Ye Lingna Su Xu he Zhiqiang Li Yu liu School of Chemical Engineering and Technology Hebei University of Technology Fujian Provincial Key Laboratory of Polymer Materials College of Chemistry and Materials Science Fujian Normal University Key Laboratory of Advanced Energy Materials Chemistry (Ministry of Education) Nankai University College of Chemistry State Key Laboratory of Elemento-Organic Chemistry Nankai University

It is a great challenge to modulate purely organic fluorescence-phosphorescence dual emission in aqueous solution because the excited singlet and triplet states are in competition with each other. herein, we report a crystalline 1:2 host-guest formed by selfassembly of 4-(4-bromophenyl)-pyridinium derivatives and cucurbit[8]uril, in which a rigid environment rich in weak interactions is directly demonstrated. Due to the inhibition of non-radiative transition and stabilization of triplet exciton in the crystalline environment, the crystalline inclusion complex exhibits ultralong room-temperature phosphorescence lifetime of 3.21 ms with an room-temperature phosphorescence(RTP) quantum yield up to 16.29%. Interestingly, the crystalline 1:2 hostguest complex demonstrates the ability of rapid identification and sensitive fluorescence-phosphorescence ratiometric detection behavior toward phenethylamine, a drug analogue, with a limit of detection as low as 27.5 nM. We believe that this study will undoubtedly broaden the utilizing scopes of RTP and offer a novel avenue for psychoactive substances monitoring.

Efficient large-area flexible organic photovoltaic modules on transparent thin silver electrodes

Science China Chemistry 2025年

作者： Cong Xie Zedong Xiong Xinlu liu wen Wang Yang liu Xueshi Jiang Xin Lu Lulu Sun Yinhua Zhou Wuhan National Laboratory for Optoelectronics Huazhong University of Science and Technology Kunming Institute of Physics

Large-area flexible organic photovoltaic（OPV） modules are challenging to achieve high power conversion efficiency（PCE）.Electrical shunts or shortages generally occur in large-area OPV modules due to the ultrathin（100–200 nm） and soft active layers. Improving the surface smoothness of bottom transparent electrode will be able to suppress the shunts and shortages. In this work, we report a method to fabricate smooth and flexible transparent electrodes based on thin silver film, and further to fabricate efficient large-area flexible OPV modules. The fabricated thin silver transparent electrodes simultaneously have high conductivity, high optical transmittance, good mechanical flexibility and low surface roughness. Humidity exposure（h.e.）treatment on MoO3effectively facilitates the continuous growth of the thin transparent silver electrode. 6 nm silver film on MoO3（h.e.） on plastic substrate shows a transmittance up to 89%, a sheet resistance of 15 Ω/sq, and a low surface roughness with a rootmean-square value of 0.276 nm. Furthermore, 52-cm2flexible organic solar modules（15 subcells） showed a certified PCE of12.66%. Furthermore, a 1350 cm2flexible component assembled by 25 pieces of 52–55 cm2modules showed certified PCE of12.10% with an open-circuit voltage of 62.85 V.

In the intricate process of natural product biosynthesis, a metabolon can enhance metabolic flux by associating sequential enzymes. A fungal metabolon, comprising of flavin-dependent monooxygenase Spe F and P450 monooxygenase Spe G, is identified in the biosynthesis of spiro polycyclic alkaloids(+)-notoamide B and its diastereomer(+)-versicolamide B. Using notoamide E as a substance, Spe F/Spe G metabolon can control the stereoselectivity of its 2,3-epoxidation, followed by hydrogen atom ion at C-17 to generate reactive epoxide tau-m A with dienyl iminium unit. Subsequently,(+)-notoamide B and(+)-versicolamide B are produced via tandem nonenzymatic inverse-electron-demand Diels-Alder reaction and semipinacol rearrangement. This provides the first example of metabolon in the biosynthesis of spiro-prenylated indole alkaloids.

为探究枯草芽孢杆菌(Bacillus subtilis)培育生物絮团对浮游生物的影响,以枯草芽孢杆菌作为试验菌种,以养殖池塘水为试验用水,在有机玻璃水族箱(100 cm×60 cm×50 cm)中进行为期40 d的生物絮团培育试验。试验以添加葡萄糖为处理组I,同时添加枯草芽孢杆菌和葡萄糖为处理II组,仅添加枯草芽孢杆菌为处理III组,对照组不添加任何物质。试验过程中每5 d对各组水体取样,对形成的絮团物质进行显微观察,同时对各组水体中浮游生物进行定性和定量分析。结果表明,本试验条件下,处理I组和处理II组在第15天左右形成成熟生物絮团,生物絮团形成前期(试验开始至第15天),生物絮团组(处理I组和处理II组)水体中浮游植物丰度显著高于处理III组和对照组,而絮团形成后期(第15~40天),生物絮团组水体中蓝藻门的微囊藻属(Microcystis)、鞘丝藻属(Lyngbya)和绿藻门的扁藻属(Platymonas)、盘藻属(Gonium)和团藻属(Volvax)的丰度显著低于处理III组和对照组,表明生物絮团的形成前期对浮游植物有明显促作用,生物絮团形成后期对蓝藻门中的微囊藻属、鞘丝藻属和绿藻门的扁藻属、盘藻属和团藻属有明显抑制效果;生物絮团形成后期,生物絮团组水体中轮虫、枝角类和桡足类浮游动物丰度显著高于处理对照III组和对照组,表明生物絮团对轮虫、枝角类和桡足类有明显促进作用。
