The application of pesticides (mostly insecticides and fungicides) during the tea-planting process will undoubtedly increase the dietary risk associated with drinking tea. Thus, it is necessary to ascertain whether pesticide residues in tea products exceed the maximum residue limits. However, the complex matrices present in tea samples comprise a major challenge in the analytical detection of pesticide residues. In this study, nine types of lateral flow immunochromatographic strips (LfIcSs) were developed to detect the pesticides of interest (fenpropathrin, chlorpyrifos, imidacloprid, thiamethoxam, acetamiprid, carbendazim, chlorothalonil, pyraclostrobin, and iprodione). To reduce the interference of tea substrates on the assay sensitivity, the pretreatment conditions for tea samples, including the extraction solvent, extraction time, and purification agent, were optimized for the simultaneous detection of these pesticides. The entire testing procedure (including pretreatment and detection) could be completed within 30 min. The detected results of authentic tea samples were confirmed by ultra-performance liquid chromatography-tandem mass spectrometry (UPLc-MS/MS), which suggest that the LfIcS coupled with sample rapid pretreatment can be used for on-site rapid screening of the target pesticide in tea products prior to their market release.

Mechanical robust and self-healing flexible perovskite solar cells with efficiency exceeding 23%

Science china chemistry 2024年第8期67卷 2670-2678页

作者： Yaohua Wang Ruikun cao Yuanyuan Meng Bin Han Ruijia Tian Xiaoyi Lu Zhenhua Song Shuncheng yang congda Lu chang Liu Ziyi Ge college of Mechanical Engineering Zhejiang University of TechnologyHangzhou 310014China Zhejiang Provincial Engineering Research center of Energy Optoelectronic Materials and Devices Ningbo Institute of Materials TechnologyEngineeringChinese Academy of SciencesNingbo 315201China center of Materials Science and Optoelectronics Engineering University of chinese Academy of Sciences Beijing 100049China

flexible perovskite solar cells(f-PScs) have experienced rapid advancements due to the light-weight, flexibility, and solution processability of the perovskite materials, which prompted the power conversion efficiency(PcE) to 24.08%. However, f-PScs still face challenges in terms of mechanical and environmental stability. This is primarily due to their inherent brittleness, the presence of residual tensile strain, and the high density of defects along the boundaries of perovskite grains. To this end, we carefully developed a cross-linkable elastomers 3-[(3-acrylamidopropyl)dimethylammonium] propanoate(ADP) with electrostatic dynamic bond, which could be in-situ cross-linked and coordinate with [Pb I6]4-to regulate the crystallization process of perovskite. The cross-linked elastomers attached to the perovskite grain boundaries could release the remaining tensile strains and mechanical stresses, leading to enhanced stability and flexibility of the f-PScs. More importantly, the electrostatic interaction between positive and negative groups of cross-linked elastomers and hydrogen bond formation between N–H and c=O accelerate the cross-linking of ADP, endowing the flexible perovskite films with self-healing ability under mild treating conditions(60 °c.f.r 30 min). As a result, the device achieves a remarkable PcE of 23.53%(certified 23.16%). Additionally, the device exhibits impressive mechanical sustainability and durability, retaining over 90% of initial PcE even after undergoing8,000 bending cycles.

Sea cucumber gut tetrapeptide ameliorates alcoholic gastric damage via restoring mitochondrial dynamics

This paper aimed to explore the mechanism of tetrapeptide VTPY in improving alcoholic gastric injury. VTPY has the potential to enhance the growth and movement of normal GES-1 cells. following ethanol-induced impairment， VTPY effectively improved migration of GES-1 and HUVEc cells， enhanced angiogenesis， eliminated cellular and mitochondrial ROS， inhibited excessive mitochondrial division， enhanced f-actin polymerization and mitochondrial respiratory capacity. To counteract excessive mitochondrial fission， VTPY primarily restores the mitochondria dynamics by reducing the expression of Drp1 and fis1， while increasing Mfn2. further studies utilizing inhibitors clarifies that the inhibition of excessive mitochondrial fission can markedly reduce f-actin depolymerization， consequently enhancing cell migration. Additionally， VTPY can inhibit the apoptosis pathway by maintaining potential of mitochondrial membrane， preventing the release of mitochondrial cytochrome c， bolstering the levels of Bcl-XL， while reducing the levels of Bax and cleaved-caspase3. further investigations using inhibitors demonstrates that excessive mitochondrial fission could activate apoptotic pathway. However， VTPY counteracts this effect and enhance cells viability. further evidence suggests that VTPY effectively improves ulcer index and pathologic changes， relieves inflammation， enhances the balance of oxidation and anti-oxidation， promotes angiogenesis， improves the expression of mitochondrial dynamics factors， blocks apoptotic pathway， and subsequently ameliorates gastric damage in mice through fis-1/Bcl-2 pathway.

采用自组装法合成了具有异质界面的f-Ti_(3)c_(2)T_(x)/ZIf-8复合材料,采用场发射扫描电子显微镜、X射线衍射、N_(2)等温吸脱附测试对合成样品的物相结构和微观结构进行了表征,并通过自行设计的四通道气敏测试设备对其气敏性能进行了研究。材料分析测试发现,形状规则的ZIf-8材料均匀分布于二维少层Ti_(3)c_(2)T_(x)的表面与层间,在界面处存在典型的异质结构。气敏性能测试表明:在225℃下,该复合材料对100μL/L NO_(2)的气敏响应高达98.35%,且是ZIf-8材料气敏响应的2.1倍。认为强导电的f-Ti_(3)c_(2)T_(x)与ZIf-8复合后形成的异质结构,不仅为ZIf-8与气体表面反应产生的自由电子提供导电通道,而且通过界面效应强化了复合材料表面气固反应时电子与空穴的分离效率,进而显著提升了复合材料对NO_(2)气体的气敏性能。同时,f-Ti_(3)c_(2)T_(x)/ZIf-8复合材料的层状结构可以为目标气体分子向ZIf-8的扩散提供方便路径。

Biochar amendment offers a chance for sustainable agriculture. However, the effectiveness of biochar relies on its physical and chemical properties, which are heavily affected by biochar production conditions and management practices. Therefore, substantial uncertainties regarding the use of biochar exist in agricultural systems *** study provides the first quantitative evaluation of the impacts of biochar characteristics and management practices on key ecosystem services by performing a second-order meta-analysis based on 34,628 paired observations in biochar-amended and unamended systems. Overall, biochar enhances phytotoxicity alleviation,physiology regulation, soil remediation and carbon sequestration, and microbial functional gene ***, some prominent trade-offs exist between crop productivity and ecosystem service deliveries including for nutrient cycling, microbial function, climate change mitigation, and the soil microbial community. The adoption of low c:N biochar produced at high pyrolysis temperatures from sewage sludge-derived feedstock, in combination with a moderate application rate and inorganic.f.rtilizer input, shows potential for achieving synergistic promotion of crop productivity and ecosystem services. These outcomes highlight the need for judicious implementation of biochar-based solutions to site-spec.f.c soil constraints. The quantified synergy and tradeoff relationships will aid the establishment of a sustainable biochar development framework that strengthens necessary ecosystem services commensurate with food security assurance.
