Micro(nano)plastics(MNPs)have become a significant environmental concern due to their widespread presence in the biosphere and potential harm to ecosystems and human ***,we propose for the first time a MNPs capture,utilization,and storage(PCUS)concept to achieve MNPs remediation from water while meeting economically productive upcycling and environmentally sustainable plastic waste management.A highly efficient capturing material derived from surface-modified woody biomass waste(M-Basswood)is developed to remove a broad spectrum of multidimensional and compositional MNPs from *** M-Basswood delivered a high and stable capture efficiency of>99.1%at different pH or salinity *** exceptional capture performance is driven by multiscale interactions between M-Basswood and MNPs,involving physical trapping,strong electrostatic attractions,and triggered MNPs cluster-like aggregation ***,the in vivo biodistribution of MNPs shows low ingestion and accumulation of MNPs in the mice *** MNPs remediation from water,the M-Basswood,together with captured MNPs,is further processed into a high-performance composite board product where MNPs serve as the glue for utilization and ***,the life cycle assessment(LCA)and techno-economic analysis(TEA)results demonstrate the environmental friendliness and economic viability of our proposed full-chain PCUS strategy,promising to drive positive change in plastic pollution and foster a circular economy.

桥墩的有效长度系数对桥墩的稳定性和强度十分重要。为解决桥墩的稳定性问题,本文建立了一种便于采用传递矩阵法求解的新颖力学模型,并基于该方法计算了多跨连续刚构桥的有效长度系数。首先,建立n跨刚构桥的一般力学模型,并利用传递矩阵法推导了其在考虑自重荷载情况下的平面内稳定特征方程,进而求得弹性屈曲载荷和有效长度系数,并将其与有限元法得到的结果进行对比,从而验证所提理论和方法的正确性。其次,研究了用碳纤维增强聚合物和超高性能混凝土加固桥墩时,桥墩有效长度系数的变化规律。最后,探讨了边跨与中跨之比、桥面梁刚度以及桥墩刚度对桥墩有效长度系数的影响。结果表明,增强整体结构刚度比增强局部刚度对提高稳定性更有效,桥梁边跨和中跨跨度对有效长度系数的影响较大。同时,还观察到碳纤维增强聚合物加固高度改变时,桥墩有效长度系数变化曲线产生了独特的双峰效应。

The urban water system theory is an extension of the basin water system science on an urban scale, providing a new systematic solution for the unbalanced human-water relationship and severe water challenges, such as waterlogging, black and odorous water, and ecological degradation caused by urbanization. Most existing studies on urban water systems have focused on individual water cycle processes linked with water supply and sewage treatment plants, but mutual feedback between the water cycle and its associated material circulation and water ecology, as well as human processes, still needs further exploration. In this paper, the concept, theory, and technical methodology of the urban water system were developed based on the water cycle and basin water system science. The Urban Water System 5.0(UWS 5.0) model was developed by integrating the Time Variant Gain rainfall-runoff Model with Urban water system(TVGM_Urban) in different underlying surface conditions for analyzing the natural-social water cycle processes and their associated water environmental and ecological processes and the influence of multiscale sponge measures. Herein, five major simulation functions were realized: rainfall-runoff-nonpoint source pollutant load,water and pollutant transportations through the drainage network system, terminal regulation and purification, socioeconomic water cycle, and water system assessment and regulation. The location for the case study used in this paper was Wuhan City. The findings showed that the entire urban water system should consider the built-up area and its associated rivers and lakes as the research object and explore the integrations among the urban natural-social water cycle and river regulations inside and outside of the city as well as the effects of socioeconomic development and sponge measures on the water quantity-quality-ecology processes. The UWS 5.0 model efficiently simulated the urban rainfall-runoff process, total nitrogen(TN) and total phosphoru
