2大气二氧化氮与每日总死亡率、心血管和呼吸系统疾病死亡率的短期关联:398个城市的多中心分析显示文摘目的:采用统一的分析方案,评估全球多个国家/地区的二氧化氮(NO_(2))与总死亡率、心血管和呼吸系统疾病死亡率之间的短期关联。研究设计:采用两阶段的时间序列分析方法、过度离散的广义线性模型和多水平meta分析。研究地点:22个低到高收入国家/地区的398个城市。主要结局指标:1973—2018年逐日总死亡人数(6280万人)、心血管疾病死亡人数(1970万人)和呼吸系统疾病死亡人数(550万人)。结果:平均而言,NO_(2)浓度在滞后1天(前1天)每增加10μg/m^(3),会导致总死亡率、心血管和呼吸系统疾病死亡率分别增加0.46%(95%可信区间0.36%~0.57%)、0.37%(0.22%~0.51%)、0.47%(0.21%~0.72%)。在对共污染物(PM_(10)、PM_(2.5)、臭氧、二氧化硫和一氧化碳)进行调整后,这些关联仍然很稳定。所有3种死因的暴露-反应曲线几乎是线性的,没有明显的阈值。在398个城市中,可归因于高过假定零水平的NO_(2)浓度造成的死亡比例为1.23%(95%可信区间0.96%~1.51%)。结论:这项多中心研究提供了关于NO_(2)短期暴露与总死亡率、心血管和呼吸系统死亡风险之间的独立和线性关联的关键证据,说明通过加强NO_(2)的控制和监管限制标准,可获得人群水平的健康收益。孟夏 刘聪(校) 陈仁杰 郑湃(译) 阚海东(校) Francesco Sera Ana Vicedo-Cabrera Ai Milojevic Maria Guo Yuming Tong Shilu Micheline de Sousa Zanotti Stagliorio Coelh Paulo Hilario Nascimento Saldiva Eric Lavigne Patricia Matus Correa Nicolas Valdes Ortega Samuel Osorio Garcia Jan Kysely Ales Urban Hans Orru Marek Maasikmets Jouni J K Jaakkola Niilo Ryti Veronika Huber Alexandra Schneider Klea Katsouyanni Antonis Analitis Masahiro Hashizume Yasushi Honda Chris Fook Sheng Ng Baltazar Nunes João Paulo Teixeira Iulian Horia Holobaca Simona Fratianni Ho Kim Aurelio Tobias Carmeníniguez Bertil Forsberg ChristoferÅström Martina S Ragettli Yue-Liang Leon Guo Shih-Chun Pan Shanshan Li Michelle L Bell Antonella Zanobetti Joel Schwartz Tangchun Wu Antonio Gasparrini 2021英国医学杂志中文版2021,24,8:7
3Direct generation of linearly polarized photon emission with designated orientations from site-controlled InGaN quantum dots显示文摘Semiconductor quantum dots(QDs)have been demonstrated viable for efficient light emission applications,in particular for the emission of single photons on demand.However,the preparation of QDs emitting photons with predefined and deterministic polarization vectors has proven arduous.Access to linearly polarized photons is essential for various applications.In this report,a novel concept to directly generate linearly-polarized photons is presented.This concept is based on InGaN QDs grown on top of elongated GaN hexagonal pyramids,by which the predefined elongation determines the polarization vectors of the emitted photons from the QDs.This growth scheme should allow fabrication of ultracompact arrays of photon emitters,with a controlled polarization direction for each individual emitter.Anders Lundskog Chih-Wei Hsu K Fredrik Karlsson Supaluck Amloy Daniel Nilsson Urban Forsberg Per Olof Holtz Erik Janzen 2014Light(Science & Applications)2014,3,1:4
4Manufacture and characterization of graphene membranes with suspended silicon proof masses for MEMS and NEMS applications显示文摘Graphene’s unparalleled strength,chemical stability,ultimate surface-to-volume ratio and excellent electronic properties make it an ideal candidate as a material for membranes in micro-and nanoelectromechanical systems(MEMS and NEMS).However,the integration of graphene into MEMS or NEMS devices and suspended structures such as proof masses on graphene membranes raises several technological challenges,including collapse and rupture of the graphene.We have developed a robust route for realizing membranes made of double-layer CVD graphene and suspending large silicon proof masses on membranes with high yields.We have demonstrated the manufacture of square graphene membranes with side lengths from 7µm to 110µm,and suspended proof masses consisting of solid silicon cubes that are from 5µm×5µm×16.4µm to 100µm×100µm×16.4µm in size.Our approach is compatible with wafer-scale MEMS and semiconductor manufacturing technologies,and the manufacturing yields of the graphene membranes with suspended proof masses were>90%,with>70%of the graphene membranes having>90%graphene area without visible defects.The measured resonance frequencies of the realized structures ranged from tens to hundreds of kHz,with quality factors ranging from 63 to 148.The graphene membranes with suspended proof masses were extremely robust,and were able to withstand indentation forces from an atomic force microscope(AFM)tip of up to~7000nN.The proposed approach for the reliable and large-scale manufacture of graphene membranes with suspended proof masses will enable the development and study of innovative NEMS devices with new functionalities and improved performances.Xuge Fan Anderson D.Smith Fredrik Forsberg Stefan Wagner Stephan Schroder Sayedeh Shirin Afyouni Akbari Andreas C.Fischer Luis Guillermo Villanueva Mikael Ostling Max C.Lemme Frank Niklaus 2020Microsystems & Nanoengineering2020,6,1:4

8斯堪的纳维亚半岛地方性和区域性大气颗粒污染对健康影响的比较评价显示文摘正在实施的'欧洲清洁空气计划'(CAFE)是欧盟委员会(TheEU Commission)的一个倡议,其目的是开展一项旨在改善欧盟空气质量的协调一致的行动。该项目关注的焦点是已经证明对人类健康有着巨大影响的颗粒物质。CAFE要求世界卫生组织(WHO)作了一份关于大气污染物和人类健康关系的最新研究进展的综述,以便在此基础上进行不同大气污染物及其对人类健康影响的评估。WHO所作的关于欧洲空气污染物对健康影响方面的综述证实,即使是较低颗粒物水平,也会对人类健康构成明显的威胁。在瑞典人口中,使用推荐的统一风险系数对颗粒物质影响的评估表明,不考虑污染源,与远程传输的人为造成的颗粒物有关的过早死亡人数,估计大概每年有3500人;相应地预期寿命减少大约7个月。当考虑地方性污染源,把现有的风险系数和暴露数据联系起来时,由于存在大量不确定因素,对地方性污染源影响的估计显得更加困难,但是估计值表明,每年大约有1800人过早死亡,他们的平均寿命大约减少了2~3个月。然而,暴露在局部污染严重、高污染物浓度下的一部分人口, 其预期寿命可能遭受更大幅度的减少。越来越多的文献资料支持燃烧形成的颗粒物具有更高相对风险的假设,因而,进一步的研究可能会转移污染控制战略的重点。CAFE项目建立了一个全面高效的降低大气颗粒物策略。根据对背景暴露值的研究,我们的结果表明,在瑞典,远程传输富含硫酸盐的颗粒是造成颗粒物质健康影响的主导因素。在整个斯堪的纳维亚半岛和很多受到越界空气污染影响的国家都会发现相同的研究结果。然而,一些包括采用高空间分辨率方法的流行病学等健康研究都表明,机动车尾气颗粒比其它颗粒物对健康更具危害性。这些互相矛盾的研究成果必须被理解,同时,应由专家给出特定污染源对人类健康影响的估算,否则不可能在欧洲找到全面高效降低大气污染性物质最有效的解决方案。我们不应满足于目前的研究结果,即认为每一种降低颗粒物浓度的措施对单位物质浓度的变化具有相同的作用。显然,我们非常需要引进更有针对性的暴露变量、更高地理分辨率的流行病学方法和健康影响效应评估。Bertil Forsberg Hans-Christen Hansson Christer Johansson Hans Areskoug Karin Persson Bengt Jrvholm 王丽荣 2005AMBIO-人类环境杂志2005,34,1:2
