Atomic layer deposition(ALD)offers unique capabilities to fabricate atomically engineered porous materials with precise pore tuning and multi-functionalization for diverse applications like advanced membrane separations towards sustainable energy-water systems.However,current ALD technique is inhibited on most non-polar polymeric membranes due to lack of accessible nucleation sites.Here,we report a facile method to efficiently promote ALD coating on hydrophobic surface of polymeric membranes via novel protein activation/sensitization.As a proof of concept,TiO2 ALD-coated membranes activated by bovine serum albumin exhibit remarkable superhydrophilicity,ultralow underwater crude oil adhesion,and robust tolerance to rigorous environments including acid,alkali,saline,and ethanol.Most importantly,excellent cyclable crude oil-in-water emulsion separation performance can be achieved.The mechanism for activation/sensitization is rooted in reactivity for a particular set of amino acids.Furthermore,the universality of protein-sensitized ALD is demonstrated using common egg white,promising numerous potential usages in biomedical engineering,environmental remediation,lowcarbon manufacturing,catalysis,and beyond.

With an increasing number of air quality monitoring stations installed around the Chinese mainland,high-resolution aerosol observations become available,allowing improvements in air pollution monitoring and aerosol forecasting.However,the multi scales(especially small-scale)information included in high-resolution aerosol observations could not be effectively utilized by the traditional three-dimensional variational method(3DVAR).This study attempted to extend the traditional 3DVAR to a multi-scale 3DVAR with two iteration steps,two-scale-3DVAR(TS-3DVAR),to improve the effectiveness of assimilating high-resolution observations.In TS-3DVAR,the large-scale and small-scale components of observation information were decomposed from the original high-resolution observations using a Gaussian smoothing method and then assimilated using the corresponding large-scale or small-scale background error covariances which were derived from the partitioned background error samples.The data assimilation(DA)analysis field generated by TS-3DVAR is more accurate than 3DVAR in reproducing the field’s multi-scale characteristics,which could thus be used as the initial chemical field of the air quality model to improve aerosol forecasting.Particulate matter with an aerodynamic diameter of less than 2.5μm(PM_(2.5))and 10.0μm(PM_(10)) from the surface air quality monitoring stations from November 01 to November 30,2018 at 00:00 were assimilated daily to verify the effects of TS-3DVAR and 3DVAR on the aerosol analysis and forecast accuracy.The results showed that TS-3DVAR better constrained both large-scale and small-scale,especially the spatial wavelengths in a range of 54-216 km and those above 351 km.The average power spectra of the TS-3DVAR assimilation increment in the two wavelength ranges were 71.70%and 35.33%higher than those of 3DVAR.As a result,the TS-3DVAR was more effective than 3DVAR in improving the accuracy of the initial chemical field,and thereby the forecasting capability for PM_(2.5).In the initial chemical field,the 30-

Three kinds of iron nanoparticles(FeNPs)were prepared via green route based on pomegranate(PG),green tea(GT),and mulberry(ML)extracts under ambient conditions.The obtained materials were characterized by scanning electron microscopy(SEM),transmission electronic microscopy(TEM),X-ray energy-dispersive spectrometer(EDS),X-ray diffraction(XRD),fourier transform infrared spectroscopy(FTIR),and X-ray photoelectron spectroscopy(XPS)techniques.The experimental results show that FeNPs were in the form of amorphous iron(Ⅱ,Ⅲ)-polyphenol complex with different dispersity and morphologies.GT-Fe has the smallest size range of 25-35 nm,PG-Fe has a moderate size-distribution of 30-40 nm,while ML-Fe formed a tuberous net-type with a sheeting structure.PG-Fe displays the highest removal efficiency of 90.2%in 20 min towards cationic dye of malachite green(16.6%by ML-Fe and 69.3%by GT-Fe),which is attributed to its highest polyphenol content,lowest zeta potential,as well as the most Fe^(2+)on the surface of FeNPs.The removal mechanism was mainly induced by electrostatic adsorption based on pH and zeta potential tests.

国家碳预算制度兼具碳排放总量控制与统计核算工具的双重功能,碳达峰目标的迫近及碳中和目标下国家降碳任务的紧迫性,使得如何将碳预算融入“双碳”目标的实践过程,实现制度和理论的双向促进成为重要问题。一方面,通过梳理碳预算制度产生的背景、碳预算概念的演变,事实印证了应对气候变化立法,是把承载全球碳排放环境容量的国际碳预算,转移至各国碳预算本土化的可靠实现方式。另一方面,域外国家应对气候变化立法的碳预算制度经验发现,其对我国碳预算目标设置、机制协同、资金渠道等方面具有重要启示。将碳预算纳入我国“双碳”目标实现的法治保障体系,可以结合已有预算法程序化规定,通过建立专门性机构、权责配置、预算调整机制、专项资金供给等制度,建构起“双碳”目标下符合我国需要的碳预算制度体系。

A three-dimensional variational(3DVAR)data assimilation(DA)system is presented here based on a size-resolved sectional aerosol model,the Model for Simulating Aerosol Interactions and Chemistry(MOSAIC)within the Weather Research and Forecasting model coupled to Chemistry(WRF-Chem)model.The use of this approach means that both gaseous pollutants such as SO2,NO2,CO,and O3 as well as particulate matter(PM2.5,PM10)observational data can be assimilated simultaneously.Two one-month parallel simulation experiments were conducted,one with the assimilation of surface hourly concentration observations of the above six pollutants released by the China National Environmental Monitoring Centre(CNEMC)and one without assimilation in order to verify the impact of assimilation on initial chemical fields and subsequent forecasts.Results show that,in the first place,use of the DA system can provide a more accurate model initial field.The root-mean-square error of PM2.5,PM10,SO2,NO2,CO,and O3 mass concentrations in analysis field fell by 29.27μg m-3(53.5%),34.5μg m-3(50.9%),30.36μg m-3(64.2%),8.91μg m-3(39.5%),0.46 mg m-3(47.4%),and 15.11μg m-3(51.0%),respectively,compared to a background field without assimilation.At the same time,mean fraction error was reduced by 42.6%,53.1%,45.2%,43.1%,69.9%,and 48.8%,respectively,while the correlation coefficient increased by 0.51,0.55,0.48,0.38,0.47,0.65,respectively.Secondly,the results of this analysis reveal variable benefits from assimilation on different pollutants.DA significantly improves PM2.5,PM10,and CO forecasts leading to positive effects that last more than 48 h.The positive effects of DA on SO2 and O3 forecasts last up to 8 h but that remains relatively poor for NO2 forecasts.Thirdly,the influence of assimilation varies in different areas.It is possible that the positive effects of DA on PM2.5 and PM10 forecasts can last more than 48 h across most regions of China.Indeed,DA significantly improves SO2 forecasts within 48 h over north China,and much longer CO assimilation benefits(4

后格拉斯哥时代解决全球气候治理问题的有效途径,在于建立一个公正合理的全球治理机制,在于激发全球公众的责任意识共同合作来应对日趋严峻的气候环境问题,因此必须诉诸根本性的气候正义理论建构与实践指导。气候正义的应然状态,建立在多元主义法哲学理论基础之上,正是吸纳了罗尔斯正义论、内格尔的霍布斯主义理论、世界主义理论的全球正义学说,引入历史唯物主义与能力主义的思考,同时融合了国际帕累托主义理论的新发展,才让气候正义的内涵与外延更加丰富。面对全球气候正义实践的实然困境,中国面临的挑战与机遇并存,致力于树立负责任的大国形象,国家应坚持“两个共同体”思想的道德立场,以争取气候谈判话语权为宗旨,秉持两类国家区别对待的双轨思路,为解决气候正义的实践困境贡献中国智慧与方案。

为分析泸定68级地震中城镇居住建筑的破坏情况,对位于震中磨西镇及周边城镇居住建筑的典型震害进行调查,总结了城镇居住建筑中框架结构及砌体结构的震害特征,详细介绍了一栋采用框架结构的高层住宅及一栋采用砌体结构的多层员工宿舍的破坏情况,并分析破坏原因。调查与分析结果表明:本次地震中,框架结构和砌体结构破坏普遍在底层更严重;框架结构震害总体较轻,未合理设计的楼梯及填充墙依然是框架结构中震害集中区;砌体结构墙体出现常见的各种斜向裂缝;除设计因素外,造成少量砌体结构倒塌可能原因是传统砌体结构抵抗竖向地震作用能力不足以及特殊场地地震放大效应。根据两种结构类型的建筑震害特征,对灾区重建及既有房屋改造提出了重点加强老旧建筑合规性排查、合理计算不利地段建筑的地震作用、适当引入合适的减隔震装置等针对性的设计建议,以提高城镇居住建筑的抗震能力,同时体现韧性城镇的设计理念。

企业合规是避免企业违法犯罪的重要手段,也是企业自身规避经营风险,实现可持续发展的重要方式。为应对当前生态环境保护、应对气候变化的新形势,有必要明确推进企业环境合规制度发展的重要价值。首先完善相关法律规范体系,明确以“立法论”路径将“双碳”目标融入刑法规制相对于“解释论”的优势与合理性。抓住刑事合规这一关键环节,推进事前合规的应用,优化对企业责任人员从宽的适用路径。进一步构建企业环境合规制度体系,促进刑事合规、行政合规等共同发展,借鉴合规援助制度等制度经验助力更大范围内合规建设的开展,充分发挥企业环境合规的制度价值与作用。

习近平总书记在党的二十大报告中明确指出要积极稳妥推进碳达峰碳中和,自我国提出“双碳”目标以来不仅在全球气候变化治理发挥了积极作用,还进一步推进了国内能源、经济等领域的低碳发展转型。通过对“双碳”目标进行辨析,相关政策与法律现状进行梳理,发现我国当前保障“双碳”目标存在专门法缺失、相关法的保障制度仍需完善、配套政策保障手段不足的问题。结合对法国、瑞典与德国三国的立法经验进行分析,基于我国国情,未来可以尝试于环境法典以可持续发展衔接“双碳”目标价值内涵,建立环境法典、单行法与政策的协同机制,推进“双碳”因素纳入环境影响评价与环境行政许可,合理衔接刑事责任的方式保障“双碳”目标的顺利实现。
