Utilizing electronic effects in the modulation of BTPhen ligands with respect to the partitioning of minor actinides from lanthanides.

چکیده
Effects of bromine substitution at the 5 and 5,6-positions of the 1,10-phenanthroline nucleus of BTPhen ligand on their extraction properties for Ln(III) and An(III) cations have been studied. Compared to C5-BTPhen, electronic modulation in BrC5-BTPhen and Br2C5-BTPhen enabled these ligands to be fine-tuned in order to enhance the separation selectivity of Am(III) from Eu(III).

It has been shown that modification of the phenanthroline backbone of CyMe4-BTPhen leads to subtle electronic modulation, permitting differential ligation of Am(III) and Cm(III) resulting in separation factors up to 7.
متن کاملConduction and Dead-Time Voltage Drops Estimation of Asymmetric Cascaded H-Bridge Converters Utilizing Level-Shifted PWM Scheme
Linear AC power supplies can be replaced by their nonlinear switching counterparts due to the lower voltage drops and higher efficiency and power density of switching-mode inverters. Multilevel cascaded H-bridge (CHB) converters are the preferred inverter structure because of modular configuration, control, and protection. The output voltage quality in CHB converters depends on the number of ou...
متن کاملEPR of Uranium. Ions
Actinides, the last known group of the Periodic Table are the subject of a special interest, both practical and scientific. Though their use is mainly based on their unique nuclear properties, the electronic structure is of no little interest because it is of paramount importance in determining the physical and chemical properties of the actinides and their compounds. Despite the common tendenc...
