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.

Magnetically responsive porous materials possess unique properties in adsorption processes such as magneticinduced separation and heat generation in alternating magnetic fields, which greatly facilitates recycling procedures, favors long-term operation, and improves desorption rate, making conventional adsorption processes highly efficient. With increasing interest in magnetic adsorbents, great progress has been made in designing and understanding of magnetically responsive porous materials varying from monoliths to nanoscale particles used for adsorption including oil uptake, removal of hazardous substances from water, deep desulfurization of fuels, and CO2 capture in the past few years. Therefore, a review summarizing the advanced strategies of synthesizing these magnetically responsive adsorbents and the utilization of their magnetism in practical applications is highly desired. In this review, we give a comprehensive overview of this emerging field, highlighting the strategies of exquisitely incorporating magnetism to porous materials and subtly exploiting their magnetic responsiveness. Further innovations for fabricating or utilizing magnetic adsorbents are expected to be fueled. The potential opportunities and challenges are also discussed.

南亚实蝇Bactroceratau(Walker)是一种重要的入侵性农业害虫.主要分布在我国云南、广东、四川和河南等地,南亚实蝇的为害严重降低了蔬菜和水果的品质.短时极端温度是影响南亚实蝇种群的重要因子.为了明确短时高低温对南亚实蝇的影响,通过选择12 h的短时低温(-4、0、4、8℃)及12 h的短时高温(34、38、42、46℃),在实验室条件下系统研究短时高低温胁迫对南亚实蝇种群生长发育和繁殖的影响.结果表明,在短时高/低温处理后,南亚实蝇各虫态的存活率随着处理温度的升高/降低逐渐下降;随着处理短时高/低温的升高/降低,南亚实蝇发育历期、产卵前期和后代性比逐渐增加;随着短时高温处理温度的升高,雌雄成虫的寿命先延长后缩短,单雌产卵量逐渐减少;随着短时低温处理温度的降低,雌雄成虫的寿命逐渐缩短,单雌产卵量先增加后减少.短时高温和短时低温均对南亚实蝇的生长发育和繁殖有着不利的影响,但一定的低温(8℃)处理后对雌成虫繁殖力有一定的促进作用.
