| 1 | Sediment fingerprinting in fluvial systems:review of tracers,sediment sources and mixing models显示文摘Suspended sediments in fluvial systems originate from a myriad of diffuse and point sources,with the relative contribution from each source varying over time and space.The process of sediment fingerprinting focuses on developing methods that enable discrete sediment sources to be identified from a composite sample of suspended material.This review identifies existing methodological steps for sediment fingerprinting including fluvial and source sampling,and critically compares biogeochcmical and physical tracers used in fingerprinting studies.Implications of applying different mixing models to the same source data are explored using data from 41 catchments across Europe,Africa,Australia,Asia,and North and South America.The application of seven commonly used mixing models to two case studies from the US(North Fork Broad River watershed) and France(BIcone watershed) with local and global(genetic algorithm) optimization methods identified all outputs remained in the acceptable range of error defined by the original authors.We propose future sediment fingerprinting studies use models that combine the best explanatory parameters provided by the modified Collins(using correction factors) and Hughes(relying on iterations involving all data,and not only their mean values) models with optimization using genetic algorithms to best predict the relative contribution of sediment sources to fluvial systems. | Arman HADDADCHI Darren S.RYDER Olivier EVRARD Jon OLLEY | 2013 | International Journal of Sediment Research2013，28，4： | 14 |
| 2 | 采用AlCl3-EMIC-MgCl2室温离子液体电沉积制备铝-镁合金显示文摘采用恒电流和恒电位技术,以及路易斯酸氯化铝(III)-1-乙基-3-甲基咪唑氯化物离子液体中添加氯化镁(II),室温下在铂和铜阴极表面电沉积制备了铝-镁合金.合金层中镁的含量随离子液体中氯化镁浓度和所施加的阴极电流密度的增加而增加.采用X-射线衍射谱(XRD)、扫描电子显微镜(SEM)和能量散射X-射线谱(EDAX)技术,研究了不同电沉积实验条件得到的电沉积层的晶体结构及表面形貌.增加沉积电流密度,可以制备出致密、光亮和结合力良好的电沉积层.铝-镁合金电沉积的阴极电流效率可达99%.应用电化学石英晶体微天平(EQCM)技术研究了电沉积合金的组成.根据重声阻抗分析得到的质量-电荷(m-Q)曲线斜率计算了金属共沉积层的化学成分. | M.Rostom Ali Andrew P.Abbott Karl S.Ryder | 2015 | 电化学2015，21，2： | 7 |

| 4 | Anodic dissolution of metals in ionic liquids显示文摘The anodic dissolution of metals is an important topic for battery design,material finishing and metal digestion.Ionic liquids are being used in all of these areas but the research on the anodic dissolution is relatively few in these media.This study investigates the behaviour of 9 metals in an ionic liquid [C_4mim][Cl] and a deep eutectic solvent,Ethaline,which is a 1:2 mol ratio mixture of choline chloride and ethylene glycol.It is shown that for the majority of metals studied a quasi-passivation of the metal surface occurs,primarily due to the formation of insoluble films on the electrode surface.The behaviour of most metals is different in [C_4mim][Cl] to that in Ethaline due in part to the differences in viscosity.The formation of passivating salt films can be decreased with stirring or by increasing the electrolyte temperature,thereby increasing ligand transport to the electrode surface. | Andrew P.Abbott Gero Frisch Jennifer Hartley Wrya O.Karim Karl S.Ryder | 2015 | Progress in Natural Science:Materials International2015，25，6： | 2 |
