铜离子催化DPKA关环反应及其潜在应用(CuⅡ-induced Ring-formation Reaction of Di-pyridylketone Azine and Its Potential Application)
二吡啶酮肼合物 离子识别 荧光 铜离子
2010/8/18
铜离子催化的氧化关环有机反应,用于选择性荧光探测金属铜离子的存在。晶体结构和光谱分析表明,在DPKA的乙腈/水混合溶剂中,引入铜离子可以促使苯并三氮唑类荧光化合物(2)的形成,该反应可以使得溶液的荧光明显增强。而且在滴定溶液里,引入Cu2+螯合剂EDTA,并不能使得溶液的荧光减弱,表明荧光是由有机物2发射的。同时,其他金属离子的引入并不能产生荧光,而且干扰离子的存在也不能使得荧光光谱发生显著改变,...
Dynamics of Agulhas Retroflection and Ring Formation in a Numerical Model. Part II. Energetics and Ring Formation
Agulhas Retroflection Ring Formation
2009/1/5
An energetics analysis of several numerical experiments on an idealized South Atlantic-Indian Ocean basin is presented. The model used in the experiments is the quasi-isopycnic coordinate model of Ble...

Agulhas Retroflection Ring Formation Vorticity Balance
2009/1/5
The Agulhas retroflection region of the wind-driven idealized South Atlantic–Indian Ocean model described by DeRuijter and Boudra is analyzed in detail. Here, in Part I, the physical mechanisms of the...
Regional Primitive Equation Studies of the Gulf Stream Meander and Ring Formation Region
Gulf Stream Meander Ring Formation Region Primitive equation
2008/12/27
Primitive equation and quasi-geostrophic eddy resolving, open ocean models are used for hindcast studies in the Gulf Stream meander and ring formation region. A feature model approach is used to initi...
