Fe-based metallic glasses (Fe–MGs) are potential candidate catalysts for advanced oxidation processes(AOPs) for recalcitrant organic pollutant degradation. However, industrial wastewater and natural contaminated sites usually contain abundant inorganic ions, like the chloride ion (Cl−), which significantly affectAOPs, but their influence on MG-activated AOPs still remains unclear. Through the study of three commonly used oxidants, hydrogen peroxide (H_(2)O_(2)), peroxydisulfate (PDS), and peroxymonosulfate (PMS), theeffect of Cl− on the FeSiB-catalyzed process of degradation of the typical azo dye Orange Ⅱ was investigated. Evidence indicates that the addition of Cl− resulted in the monotonous inhibition of the degradation process when the H_(2)O_(2)/FeSiB and PDS/FeSiB systems were employed, but promoted effect wasdetected with the PMS/FeSiB system, which is different from the previously observed dual effect of Cl−.It is closely relative with FeSiB induced unique variety of degradation pathways, including radicals, nonradicals (^(1)O_(2)), and direct reduction degradation. Moreover, the presence of Cl− significantly affected thesystems’ absorbable organic halogen content and the amount of Fe leached into the solution. The resultsof this work will provide essential references for Fe-based MG used as AOP catalysts in field applicationsand the development of advanced MGs with excellent adaptability to complex environments.

目的:研究宁波市社区养老服务供需现况,并分析问题和提出对策。方法:采用问卷现场调研宁波市8个社区的400名社区老年人。采用访谈法调研4家社区养老服务中心。结果:60~69岁社区老年人主要需要精神文化方面的养老服务,70~79岁社区老年人主要需要基本的医疗康复和安全保障,80岁及以上社区老年人主要需要生活照料和医疗康复服务。在是否愿意参加社区活动的调查中,有43%的社区老年人选择一般愿意。在社区养老服务满意度调查中,有53%的社区老年人选择基本满意。社区养老服务中心的服务供给情况显示,大部分社区养老服务中心可以提供生活照料和健康护理,但对精神慰藉和身心健康服务提供不足。结论:社区老年人轻度功能障碍者所占比例最大。不同年龄的社区老年人服务需求不同。同时,社区老年人对社区组织活动参与意愿不高,对提供的社区养老服务内容基本满意。因此,需要全面深入评估社区老年人的服务需求,并针对性地提高养老服务供给水平。

Metamaterials such as architected lattice structures have aroused broad interest in being applied as mechanical supports for their lightweight and custom-shaped *** various prior efforts have been devoted,a multiscale fabrication of micro-nano lattice structures without penalizing the mechanical properties is still a challenging but highly desirable *** we put forward a strategy to produce a mechanically enhanced micro-nano lattice structure by conformally depositing a CoCrFeNiTi high-entropy alloy(HEA) coating layer onto a three-dimensional(3D) printed polymer *** template for the 3D printing employs a six-membered tricapped trigonal prism(6M-TTP) structure derived from a medium-range order structure motif in amorphous *** topological complexity of the 6M-TTP can substantially avoid the stress concentration by offering stress-release channels,while the HEA film incorporating with amorphous and nanocrystalline constituents can further reinforce the lattice architecture through its size hardening *** from the above,the fabricated polymer/HEA-hybrid lattice exhibits a high specific compressive strength(～0.055 MPa kg-1m3at a density below 500 kg m-3),a superior elastic recoverability(～70% recovery rate under>30% compression),an enhanced plasticity(40% strain) and a high specific modulus(0.135 MPa kg-1m3).Our strategy initiates a perspective way to fabricate multiscale micro-nano lattice structures with improved mechanical properties,which could be extended to widespread metamaterial research.

A common view on meridional deflection of eddy propagation is poleward for cyclones and equatorward for anticyclones. This widely accepted polarity-sensitive pattern has been increasingly undermined given that it is systematically violated on both zonal and regional scales as recently reported. Here, we approach the problem by exploring these violations in terms of eddy effects of spatiotemporal geostrophy, thermal fading, and flow dragging, yielding the following main conclusions.(1) The polarity-dependent deflection discrepancy is a pseudo feature resulting from a biased fit to the normalized eddy tracks which are spatially asymmetric(though azimuthally symmetric) between the two signs;Instead, the primary pattern of eddy deflection appears to be geographically correlated and polarity independent.(2) Geostrophic adjustment plays a critical role in defining the meridional movement of an eddy. Specifically, a consistent poleward(equatorward) trajectory bending of spatially(temporally) ageostrophic eddies is observed irrespective of their polarity.(3) The mechanism of eddy deflection is also determined by its zonal propagation direction. Westward propagating eddies are substantially affected by thermal fading, while opposite ones by flow dragging. A realistic and comprehensive understanding of eddy deflection mechanisms serves as a significant contribution to the prediction of eddy trajectory, and the protection of ocean environment.
