Epidemiological studies have suggested that inhalation exposure to indoor ambient air from coal-burning environments is causally associated with respiratory health *** order to explore the toxicological mechanisms behind the adverse health effects,the hemolytic activity of PM_(10)(particulate matter with an aerodynamic diameter of 10 um or less)samples collected from homes burning coal in the recognized China"cancer village"Xuanwei were evaluated and matched against their trace elemental *** results demonstrated that the hemolytic activity of indoor PM_(10) in coal-burning environments ranged from 4.28%to 5.24%,with a clear positive dose-response *** low dose samples exhibited a reduced hemolytic activity,PM_(10) could have a toxic effect upon people in a coal-burning indoor environment for extended time *** concentrations of analyzed trace elements in PM_(10) samples ranged from 6966 to 12,958 *** the analyzed elements,Zn,Ti,Ni,Cu,Pb,Ba,Mn,Cr and V were found at higher concentrations and accounted for over 95%of the total *** concentrations of total analyzed elements in the PM_(10) samples revealed a significant positive correlation with PM_(10) hemolytic *** the analyzed elements,Zn,Pb and Cs positively correlated with hemolysis,while Li,U and V negatively correlated with the hemolysis of human red blood cells(RBCs).Therefore,the heavy metal elements could be one of the main factors responsible for the hemolytic capacity of indoor PM_(10) in coal-burning environments.

The surface stability of coinage metals is paramount when they are used as electrode materials for functional electronic devices incorporating organic semiconductors. In this work, it is shown that the adsorption of non-planar vanadyl phthalocyanine molecules on Cu（110） drastically restructured the metal surface at room temperature, which was further enhanced upon moderate annealing. Scanning tunneling microscopy imaging demonstrated that the surface was restructured at step edges into sawtooth features that gradually replaced the （110） terraces. The edges of the modified steps were preferentially composed of chiral （1×6） kink sites decorated with vanadyl phthalocyanine molecules adsorbed in a tilted configuration with the oxygen atom pointing downwards. These results can have a strong impact on the optimization of the performance of organic devices integrated with phthalocyanine molecules.

前言第五代(5G)无线基础设施不仅为新应用开辟了道路,还极大地改善了4G及前几代无线应用。随着5G网络性能的提高,通信速度将更快,延迟更低,交互性也更佳。这对消费者体验和机器对机器(M2M)通信来说都是好消息。5G将通过单一移动网络提供以下三种服务:一是增强型移动宽带(eMBB),满足以人为中心的内容和服务接入用例需求;二是大规模机器类通信(mMTC),在要求不高的低功耗设备之间进行数据交换;三是超高可靠超低时延通信(URLLC),在要求非常严格的设备之间进行数据交换。本文将探讨5G增强技术如何改进现有应用,并为更具创新性的应用创建平台。

本文使用高分辨率环境扫描电镜和图像分析技术对北京PM中的矿物颗粒的微观形貌和粒度分布特征进行了研究,结果表明,北京PM中的矿物颗粒按其形貌、组成特点可以分为单矿物和矿物集合体两类,矿物颗粒多以不规则的形态出现,形态规则的矿物主要是硫酸盐类矿物,是大气化学反应的产物;形态不规则的矿物是来自扬尘的原生矿物。PM中矿物颗粒的粒度分布特征在不同类型污染现象产生的PM中表现不同,在沙尘暴样品和道路扬尘样品中,矿物颗粒的粒度峰值在1～2.5μm;在局地扬尘的样品中,矿物颗粒的粒度较粗,主要分布在1～2.5μm和2.5～10μm。
