The prospect of combining both magnetic and plasmonic properties in a single nanoparticle promises both valuable insights on the properties of such systems from a fundamental viewpoint and numerous possibilities for technological applications. However, the combination of two of the most prominent metallic candidates—iron and silver—has presented numerous experimental difficulties because their thermodynamic properties impede miscibility and even coalescence. Herein, we present the thorough characterization of physically prepared Fe50Ag50 nanoparticles embedded in carbon and silica matrices via electron microscopy, optical spectroscopy, magnetometry and synchrotron-based X-ray spectroscopy. Iron and silver segregate completely into structures resembling fried eggs, with a nearly spherical, crystallized silver part surrounded by an amorphous structure of iron carbide or oxide, depending on the environment of the particles. Consequently, the particles exhibit both plasmonic absorption corresponding to the silver nanospheres in an oxide environment and a reduced but measurable magnetic response. The suitability of such nanoparticles for technological applications is discussed from the viewpoint of their high chemical reactivity with their environment.

Environmental Science and Ecotechnology 2021年第4期8卷 22-30页

作者： Dominik Buchner Till-Hendrik Macher Arne j.Beermann marie-Therese Werner Florian Leese University of Duisburg-Essen Aquatic Ecosystem ResearchUniversitatsstr.545141EssenGermany University of Duisburg-Essen Centre for Water and Environmental Research(ZWU)Universitatsstr.345141EssenGermany

Reliable and comprehensive monitoring data are required to trace and counteract biodiversity loss. Highthroughput metabarcoding using DNA extracted from community samples (bulk) or from water orsediment (environmental DNA) has revolutionized biomonitoring, given the capability to assess biodiversity across the tree of life rapidly with feasible effort and at a modest price. DNA metabarcoding canbe upscaled to process hundreds of samples in parallel. However, while automated high-throughputanalysis workflows are well-established in the medical sector, manual sample processing still predominates in biomonitoring laboratory workflows limiting the upscaling and standardization for routinemonitoring applications. Here we present an automated, scalable, and reproducible metabarcodingworkflow to extract DNA from bulk samples, perform PCR and library preparation on a liquid *** features are the independent sample replication throughout the workflow and the use of manynegative controls for quality assurance and quality control. We generated two datasets: i) a validationdataset consisting of 42 individual arthropod specimens of different species, and ii) a routine monitoringdataset consisting of 60 stream macroinvertebrate bulk samples. As a marker, we used the mitochondrialCOI gene. Our results show that the developed single-deck workflow is free of laboratory-derivedcontamination and produces highly consistent results. Minor deviations between replicates are mostlydue to stochastic differences for low abundant OTUs. Thus, we successfully demonstrated that roboticliquid handling can be used reliably from DNA extraction to final library preparation on a single deck,thereby substantially increasing throughput, reducing costs, and increasing data robustness for biodiversity assessments and monitoring.

Aims: The purpose of the Euro Heart Survey Programme of the European Society of Cardiology is to evaluate to which extent clinical practice endorses existing guidelines as well as to identify differences in population profiles, patient management, and outcome across Europe. The current survey focuses on the invasive diagnosis and treatment of patients with established coronary artery disease(CAD). Methods and results: Between November 2001 and March 2002, 7769 consecutive patients undergoing invasive evaluation at 130 hospitals(31 countries) were screened for the presence of one or more coronary stenosis >50%in diameter. Patient demographics and comorbidity, clinical presentation, invasive parameters, treatment options, and procedural techniques were prospectively entered in an electronic database(550 variables+29 per diseased coronary segment). Major adverse cardiac events(MACE) were evaluated at 30 days and 1 year. Out of 5619 patients with angiographically proven coronary stenosis(72%of screened population), 53%presented with stable angina while ST elevation myocardial infarction(STEMI) was the indication for coronary angiography in 16%and non-ST segment elevation myocardial infarction or unstable angina in 30%. Only medical therapy was continued in 21%, whereas mechanical revascularization was performed in the remainder[percutaneous coronary intervention(PCI) in 58%and coronary artery bypass grafting(CABG) in 21%]. Patients referred for PCI were younger,were more active, had a lower risk profile, and had less comorbid conditions. CABG was performed mostly in patients with left main lesions(21%), two-(25%), or three-vessel disease(67%) with 4.1 diseased segments, on average. Single-vessel PCI was performed in 82%of patients with either single-(45%), two-(33%), or three-vessel disease(21%). Stents were used in 75%of attempted lesions,with a large variation between sites. Direct PCI for STEMI was performed in 410 cases, representing 7%of the entire workload in the

断裂带的变形行为和断层滑移机制是目前地震研究关注的热点,断裂带岩石特征、内部结构与物理化学性质是确定断层蠕滑或粘滑行为以及断层滑移机制的基础和关键。本文以鲜水河断裂带乾宁段地表出露的断裂岩为研究对象,通过野外地质调查、室内光学显微镜、扫描电镜、粒度统计、粉末X射线衍射分析(XRD)和薄片X射线荧光光谱分析(XRF)等多种研究方法,对鲜水河断裂带岩石特征、结构构造、物性、矿物成分及化学元素分布开展了详细的分析,并探讨了相关变形行为和滑移机制。分析表明:(1)断裂带核部主要由黑色断层泥、浅黄色及黄色断层角砾岩和灰色碎裂岩、灰色断层角砾岩组成,呈单核对称结构;(2)黑色断层泥厚3~5cm,具有快速滑动结构特征,表现为断层粘滑行为。断层泥可划分出13个滑移带,最窄滑移带厚约40μm,至少代表13期古地震事件;(3)断层泥主要由伊利石、高岭石和石英等矿物组成,其中边部伊蒙混层含量异常高,为最新一次古地震的主滑移带。由于伊利石和伊蒙混层(或蒙脱石)为主要黏土矿物的断层泥渗透率低、孔隙流体压力大,以及发现断层泥楔入脉,表明地震过程中断层滑动存在热增压弱化机制;(4)从断层泥不同滑动带中碎块蚀变程度和矿物分布特征来看,地震主滑动带有向碎裂岩方向迁移的趋势。推测断层在滑动过程中,更趋向于向弱矿物含量高(如伊利石、伊蒙混层)、强矿物含量低(如方解石、高岭石)的围岩一侧迁移。
