Intensified demulsification and separation of thermal oxide reprocessing interfacial crud (THORP-IFC) simulants

Green Processing and Synthesis, 2012
Reprocessing of spent nuclear fuel for the recovery of the fissionable materials (mainly uranium and plutonium), is performed by solvent extraction. Thermal oxide reprocessing (THORP) is the most widely used technique in which processing fluids gradually

Size-Reduction of a Dual-Band Circularly Polarized Dielectric Resonator Antennas

IEEE Access, 2021
In this paper, the size reduction of a dual-band circularly polarized (CP) Y-shaped dielectric resonator antenna (YDRA) is performed. Unlike the conventional CP DRAs, the circular polarization in the YDRA is achieved by the combination of linearly ...
