| 1 | Raman Spectroscopic Study of Silicon Nanopowders显示文摘Vibrational properties of silicon nanopowders are discussed with reference to Raman spectroscopic measurements. The powders were produced in a low pressure rf plasma from the cluster induced agglomeration of positive ions formed during the dissociation of silane. Influence of thermal treatment and the crystallization phenomena of the powder were studied. Raman spectroscopic measurements reveal size quantization effects for the particles as well as the existence of partially ordered regions in the apparently amorphous primary particles. The crystalline and amorphous volume fraction in the material were calculated from the relative spectraI intensities. The results obtained in these experiments are consistent with the observations from recent high resolution transmission electron microscopy studies of these | S.M.Scholz J.Dutta and H.Hofmann(Lab. de Technologie des Poudres, Departement de Materiaux, Ecole Polytechnique Federale de Lausanne,1015 Lausanne, Switzerland)H.Hofmeister (Max-Planck-Institut fur Mikrostrukturphysik, Weinberg 2, D-06120 Halle, Germany) | 1997 | Journal of Materials Science & Technology1997，13，4： | 3 |
| 2 | Development of a Rapid Risk and Impact Assessment Tool to Enhance Response to Environmental Emergencies in the Early Stages of a Disaster: A Tool Developed by the European Multiple Environmental Threats Emergency NETwork (EMETNET) Project显示文摘Every year,numerous environmental disasters and emergencies occur across the globe with far-reaching impacts on human health and the environment.The ability to rapidly assess an environmental emergency to mitigate potential risks and impacts is paramount.However,collating the necessary evidence in the early stages of an emergency to conduct a robust risk assessment is a major challenge.This article presents a methodology developed to help assess the risks and impacts during the early stages of such incidents,primarily to support the European Union Civil Protection Mechanism but also the wider global community in the response to environmental emergencies.An online rapid risk and impact assessment tool has also been developed to promote enhanced collaboration between experts who are working remotely,considering the impact of a disaster on the environment and public health in the short,medium,and long terms.The methodology developed can support the appropriate selection of experts and assets to be deployed to affected regions to ensure that potential public health and environmental risks and impacts are mitigated whenever possible.This methodology will aid defensible decision making,communication,planning,and risk management,and presents a harmonized understanding of the associated impacts of an environmental emergency. | Emma-Jane Goode Eirian Thomas Owen Landeg Raquel Duarte-Davidson Lisbeth Hall Jolanda Roelofs Sjors Schulpen Arnout De Bruin Elisabeth Wigenstam Birgitta Liljedahl Annica Waleij Louise Simonsson Ann Göransson Nyberg | 2021 | International Journal of Disaster Risk Science2021，12，4： | 2 |
| 3 | Metabolic responses of Eucalyptus species to different temperature regimes显示文摘Species and hybrids of Eucalyptus are the world's most widely planted hardwood trees. They are cultivated across a wide range of latitudes and therefore environmental conditions. In this context, comprehensive metabolomics approaches have been used to assess how different temperature regimes may affect the metabolism of three species of Eucalyptus, E. dunnii, E. grandis and E. pellita.Young plants were grown for 53 d in the greenhouse and then transferred to growth chambers at 10°C, 20°C or30°C for another 7 d. In all three species the leaf chlorophyll content was positively correlated to temperature, and in E.pellita the highest temperature also resulted in a significant increase in stem biomass. Comprehensive metabolomics was performed using untargeted gas chromatography mass spectrometry(GC-MS) and liquid chromatography(LC)-MS.This approach enabled the comparison of the relativeabundance of 88 polar primary metabolites from GC-MS and625 semi-polar secondary metabolites from LC-MS. Using principal components analysis, a major effect of temperature was observed in each species which was larger than that resulting from the genetic background. Compounds mostly affected by temperature treatment were subsequently selected using partial least squares discriminant analysis and were further identified. These putative annotations indicated that soluble sugars and several polyphenols, including tannins, triterpenes and alkaloids were mostly influenced. | Joao Benhur Mokochinski Paulo Mazzafera Alexandra Christine Helena Frankland Sawaya Roland Mumm Ric Cornelis Hendricus de Vos Robert David Hall | 2018 | Journal of Integrative Plant Biology2018，60，5： | 2 |
