| dc.description.abstract | From an engineering perspective, Rare Earth elements have the potential to transform technology in previously unprecedented ways. Their magnetic, luminescent, and electromechanical capabilities are allowing electronic devices to become more compact, reduce emissions, operate more efficiently, and cost less to produce and purchase. Such developments are proving beneficial to the economies of many developed nations because of their use in popular everyday consumer technologies as well as industries such as energy. Along with this positive impact comes a political overlay that threatens the longevity of Rare Earth use. Presently, Rare Earths are expensive and dangerous to extract. This is largely due to the fact that they are not found together in large concentrations, so it is only economically feasible to extract them with another material, such as coal or minerals. The process of extraction is also hazardous and cumbersome; separating Rare Earths from other materials involves processes with high levels of emissions that may be dangerous to human beings if overexposure occurs. On the other hand, nations with more flexible safety and health regulations are investing in the development of Rare Earths and setting themselves apart as production leaders. Nations with more stringent health and safety regulations are becoming dependent on these nations to provide the Rare Earths for their applications. As a result, leaders in engineering industry can only benefit from Rare Earths if they optimize on the current supply economically. The possibility of extracting Rare Earths through more efficient, safer processes is becoming recognized as a relevant topic of research. Additionally, investigation into alternatives to Rare Earths in some of the more common applications may allow for safer and less politically charged production methods for many 21st Century advancements. | |
