1挪威湖泊沉积物中的微量元素污染显示文摘我们用挪威210个湖泊表层沉积物和工业化前沉积物中锑、汞、铋、镉、钼、砷、钴、镍、铬、铜、钒、铅和锌的浓度,研究了它们的近代大气沉积物。水表层沉积物中锑、汞、铋、镉、砷、铅的浓度比工业化前的沉积物高得多。差异随纬度和海拔的增高而缩小。对表层沉积物微量元素和主要成分(有机物、硅、铝、铁和锰)的多变量分析表明:锑、汞、铋、砷和铅组成一组,它们与有机物紧密相关。镍、铬和铜与无机沉积物部分(硅、铝)有微弱的相关而形成第二组。锌和镉与有机物微弱相关构成第三组。钴和锰相关,而钼和钒对其他微量元素和主要成分没有表现出明显的共变性。Sigurd Rognerud Eirik Fjeld 郑萧 2001AMBIO-人类环境杂志2001,30,1:15

3Leaching behavior of enrofloxacin in three different soils and the influence of a surfactant on its mobility显示文摘The leaching behaviors of enrofloxacin (ENR), a fluoroquinolone group antibiotic, in three different standard soils, namely sandy, loamy sand and sandy loam were investigated according to OECD guideline 312. In addition, the effects of tenside, sodium dodecylbenzenesulfonate (DBS) on the mobility of ENR in two different soils were studied. The mobility of ENR in all three standard soils was very similar and was mostly (98%) concentrated on the top 0-5 cm segment of the soils at pH 5.7. The DBS can enhance the mobility of ENR in soils but the impact was in general negligible under the studied conditions.Zhiyong Yu Ayfer Yediler Min Yang Sigurd Schulte-Hostede 2012Journal of Environmental Sciences2012,24,3:5
4MICROMECHANICS OF MACROELECTRONICS显示文摘The advent of flat-panel displays has opened the era of macroelectronics. Enthusiasm is gathering to develop macroelectronics as a platform for many technologies, ranging from paper-like displays to thin-film solar cells,technologies that aim to address the essential societal needs for easily accessible information, renewable energy, and sustainable environment. The widespread use of these large structures will depend on their ruggedness, portability and low cost, attributes that will come from new material choices and new manufacturing processes. For example, thin-film devices on thin polymer substrates lend themselves to roll-to-roll fabrication, and impart flexibility to the products. These large structures will have diverse architectures, hybrid materials, and small features; their mechanical behavior during manufacturing and use poses significant challenges to the creation of the new technologies. This paper describes ongoing work in the emerging field of research - the mechanics of macroelectronics, with emphasis on the mechanical behavior at the scale of individual features, and over a long time.Zhigang Suo Joost Vlassa Sigurd Wagner 2005China Particuology2005,3,6:5
