Methane, an abundant one-carbon（C1） resource, is extensively used in the industrial production of vital fuels and value-added chemicals. However, current industrial methane conversion technologies are energy-and carbon-intensive, mainly due to the high activation energy required to break the inert C–H bond, low selectivity, and problematic side reactions, including CO2emissions and coke deposition. Electrochemical conversion of methane（ECM） using intermittent renewable energy offers an attractive solution, due to its modular reactor design and operational flexibility across a broad spectrum of temperatures and pressures. This review emphasizes conversion pathways of methane in various reaction systems, highlighting the significance and advantages of ECM in facilitating a sustainable artificial carbon cycle. This work provides a comprehensive overview of conventional methane activation mechanisms and delineates the complete pathways of methane conversion in electrolysis contexts. Based on surface/interface chemistry, this work systematically analyzes proposed reaction pathways and corresponding strategies to enhance ECM efficiency towards various target products, including syngas, hydrocarbons, oxygenates, and advanced carbon materials. The discussion also encompasses opportunities and challenges for the ECM process, including insights into ECM pathways, rational electrocatalyst design, establishment of benchmarking protocols, electrolyte engineering, enhancement of CH4conversion rates, and minimization of CO2emission.

La3＋ and V5＋ co-doped BiFeO3 ceramics are synthesized by rapid liquid sintering technique. The modulated structure in Bi0.85La0.15Fe0.97V0.03O3 is investigated by using transmission electron microscopy （TEM）. Two kinds of superstructures are observed in the samples. One is the component modulated superstructure and twin-domain, which is generated by La3＋ ordered substitution for Bi3＋ and frequently appears. The chemical composition of the superstructure is explored by x-ray energy dispersive spectroscopy （EDS）. The model of the ordered structure is proposed. Simulation based on the model is conducted. The second is the fluorite-type δ-Bi2O3 related superstructure. The relation between the ferroelectric property and the microstructure of the sample is also discussed.

Meningeal lymphatic vessels form a relationship between the nervous system and periphery, which is relevant in both health and disease. Meningeal lymphatic vessels not only play a key role in the drainage of brain metabolites but also contribute to antigen delivery and immune cell activation. The advent of novel genomic technologies has enabled rapid progress in the characterization of myeloid and lymphoid cells and their interactions with meningeal lymphatic vessels within the central nervous system. In this review, we provide an overview of the multifaceted roles of meningeal lymphatic vessels within the context of the central nervous system immune network, highlighting recent discoveries on the immunological niche provided by meningeal lymphatic vessels. Furthermore, we delve into the mechanisms of crosstalk between meningeal lymphatic vessels and immune cells in the central nervous system under both homeostatic conditions and neurodegenerative diseases, discussing how these interactions shape the pathological outcomes. Regulation of meningeal lymphatic vessel function and structure can influence lymphatic drainage, cerebrospinal fluid-borne immune modulators, and immune cell populations in aging and neurodegenerative disorders, thereby playing a key role in shaping meningeal and brain parenchyma immunity.

ZnSe nanoribbons were synthesized with chemical vapor deposition route. The excitation power-dependent photol and surface photovoltage （SPV） techniques were used to study the optoelectronic properties of the as-grown ZnSe nanoribbons. Three deep defect （DD）-related emission bands, respectively, centered at 623 nm （DD1）, 563 nm （DD2） and 525 nm （DD3）, emerge orderly with increasing the excitation power, which is attributed to the saturation of the DD states from deeper to shallower level. The SPV spectrum and the corresponding phase spectrum show that DD1 mainly acts as recombination center, while DD2 and DD3 can act as both the recombination center and electron traps. The influence of the trapping electrons on the SPV response dynamic was studied with transient SPV.

The Pomacea canaliculata, also known as apple snail, is an invasive species in China, posing a serious threat to agricultural production and public health. To prevent its rampant infestation, we developed a highly efficient snail-killing lead compound, 1-(4-chlorophenyl)-3-(pyridin-3-yl)urea (PBQ). However, the killing mechanism of PBQ remains unclear. To elucidate this, two novel compounds, B-PBQ and J-PBQ, were developed through structural modification of PBQ and were used, through both protein pull-down assay and confocal laser scanning microscopy imaging, to identify and confirm that phosphofructokinase(PFK) in the apple snail is the primary target protein of PBQ. Further studies revealed that PBQ successfully inhibits the activity,content, and expression of PFK in apple snail, disrupting the glycolysis pathway and leading to abnormal energy *** disruptions impair the snail’s tolerance to low oxygen, resulting in its efficient eradication. These findings offer a promising direction for developing next-generation PFK-targeted snail-killing pesticides. Furthermore, the strategy of combining pull-down assays with optical imaging used in this work provides a novel approach for the exploration of mechanisms of other pesticide candidates.

A simple and effective process has been reported to prepare the silver(Ag)/graphene composite with excellent mechanical and electrical properties based on high-quality graphene(HQG).The HQG was fabricated via hot pressing of reduced graphene oxide(RGO) from chemical exfoliation,while the Ag/HQG composite was obtained by using spark plasma sintering(SPS) treatment under high temperature(1500℃) and moderate pressure(40 MPa).With low oxygen-containing functional groups and defect density,the HQG dispersed homogeneously in the composite after high-energy ball *** comparison to pure Ag,the as-prepared Ag/RGO composite exhibited a great enhancement of 11% electrical conductivity and 42% micro-hardness with an optimal RGO adding content(1 wt%).The Ag/HQG composite is expected to open up a new way for the novel Ag-based electrical contact materials,and further to broaden its applications in micro-electronics and switching power.
