Yttriumum was classified as a heavy rare earth element, not a light rare earth element. The light rare earth elements include Lanthanum, Cerium, Prasteremium, neodymium, Promethium, Samarium, and Europium. Yttriumum belonged to the group of heavy rare earth elements, and together with terbium-based rare earth elements, they were known as the rare earth elements of the group of rare earth elements. Therefore, it was not a light rare earth.
The uniqueness of rare earth fiction novels lies in their focus on resources that are not commonly the central theme in mainstream fiction. Rare earths are vital for modern technology, so these novels can explore the impact of their scarcity or discovery on society.
Well, I'm not sure if there are a large number of novels that are specifically and solely about 'rare earths' in the title. However, some science fiction novels that deal with advanced technology and resource management on other planets or in the future might involve rare earths. For instance, Arthur C. Clarke's works often explore such scientific and technological concepts. His novels might not directly mention 'rare earths' but could potentially have elements related to the importance of such scarce resources in the development of advanced civilizations.
I recommend " Time Travel: The Rules of Trading in Other Worlds " to you. The protagonist of this novel, Mu Li, is a businessman. She has three rules for trading: what she likes, what she is willing to do, and what makes the most money. Other than the things she didn't like, she could offer any rare treasure from a different time and space as long as the other party could afford it. This novel meets your requirements. Everything that leaves Earth will become a rare treasure. I hope you like my recommendation.
Yes, 'The Love Hypothesis' started as a Reylo fanfic (Rey and Kylo Ren from Star Wars). It was later adapted into an original novel, but its origins were in fanfiction.
Sure, it is. 'The Love Hypothesis' tells a tale that might capture your heart. It has all the elements of a great story - romance, drama, and maybe a few surprises.
