Structural differences between light and heavy rare earth element binding chlorophylls in naturally grown fern Dicranopteris linearis. Biol. Trace Elem. Res. 106, 279-297.Wei, Z., Hong, F., Yin, M., Li, H., Hu, F., Zhao, G., Wong, J.W., 2005. Structural differences between light...
In the base or basic melt, the rare earth elements in these minerals are incompatible elements, LREE fractionation is weak. In the acidic melt, light and heavy rare earth elements in the above-mentioned mineral carve differentiation enhancement. Therefore, in the same magma series, the fractionati...
A novel separation strategy for light REEs (Ce4+ and La3+) and heavy REEs (Y3+ and Eu3+) from a low-grade monazite ore leached solution in a sulfate medium was studied to achieve a higher selectivity of metal ions. A prior separation of higher valence Ce4+ was performed using 8.0 vol...
alight rare earth 轻稀土元素[translate] aREE is characterized as relatively rich in light rare earth,high fractionation of light and heavy rare earth allow,and negative amomalies of Ce,Eu. REE被描绘和相对地富有在轻的稀土元素,高分馏轻和重稀土元素准许和铈,欧共体消极amomalies。[translate]...
The effects of rare earth elements with different content on anti declining property of Y base heavy rare earth magnesium and cerium base light rare earth magnesium nodular cast iron were studied. The relationships between the sphericized grade of the liquid iron treated by different nodulizer and ...
(Tech Xplore)—Anticipate this: a car's motor magnet that does not have heavy rare earth elements. That is big, in that it marks a break from several constraints.
In this paper,the light rare earth-magnesium noduliztion alloys and inoculation alloys that has been used in produecting heavy section ductile iron rollers are introduced. 叙述生产轧辊类超厚大断面球墨铸铁件所用的轻稀土镁球化剂、孕育剂和复合球化、孕育处理过程及其对原铁水的要求,同时介绍了所生产...
Rare earth elements can be divided into light rare earth and heavy rare earth, mainly in the form of rare earth oxides. China, Russia, the United States and Australia lead the world in rare earth reserves. Rare earth is mainly used in...
A series of lanthanide coordination polymers(LnCPs) containing both light and heavy rare-earth elements, namely {[Eu 2 (pydc) 3 (H 2 O)]·2H 2 O} n (1-Eu, H 2 pydc = pyridine-2,3-dicarboxylic acid), [Ln(pyc) 2 (Hpyc)(NO 3 )] n (Ln = Nd (2-Nd), Sm (3-Sm), Eu...
Relatively enriched in light rare earth elements, the fractionation is more obvious, the fractionation of heavy rare earth elements is not obvious, the internal fractionation of light rare earth elements than the internal fractionation of heavy rare earth, some form of distribution of heavy rare ear...
