Study Level Recovery Processes Of Thorium And Several Rare Earth Elements From Monazite Ore, Makayla Hyde, Jaclyn Choate
Study Level Recovery Processes Of Thorium And Several Rare Earth Elements From Monazite Ore, Makayla Hyde, Jaclyn Choate
EURēCA: Exhibition of Undergraduate Research and Creative Achievement
Monazite ore is composed of several minerals including several rare earth element (REE) and thorium phosphates. Many past research projects have looked at the extraction of REE from monazite ore but have discarded the thorium phosphate compound as waste. Since thorium could be a possible fuel for state-of-the-art future nuclear reactors, this research focuses on a way to recover thorium from the monazite ore. The overall purpose of this research is to develop a conceptual recovery process that recovers thorium dioxide from monazite ore. In some parts of the world where uranium sources are limited; then, thorium could be used …

Synthesis Of Ptcuco Ternary Alloy Using Laser Ablation Synthesis In Solution-Galvanic Replacement Reaction (Lasis-Grr), Kangmin Cheng
EURēCA: Exhibition of Undergraduate Research and Creative Achievement
Laser ablation synthesis in solution in tandem with galvanic replacement reaction (LASiS-GRR) is a newly-developed, facile and environmental friendly synthesis technique for manufacturing a variety of complex nanostructures including hydroxides, metal/metal oxides nanocomposites (NCs), metal-metal nanoalloys (NAs), core-shell nanostructures, etc. This synthetic technique incorporates both “top-down” pulsed laser ablation synthesis in solution approach (LASiS) and the “bottom-up” chemical reduction method (CRM). The setup houses a Q-switched Nd:YAG pulsed laser (1064 nm) with the laser beam focused at a metal target in liquid medium inside a sealed stainless steel reactor cell. The cell is mounted with a gas inlet/outlet, viewing windows, …
