source:NewwiseNewswise — Material scientists have developed a fast method for producing epsilon iron oxide and demonstrated its promise for next-generation communications devices. Its outstanding magnetic properties make it one of the most coveted materials, such as for the upcoming 6G generation of communication devices and for durable magnetic recording. The work was published in the Journal of Materials Chemistry C, a journal of the Royal Society of Chemistry.Iron oxide (III) is one of the most widespread oxides on Earth. It is mostly found as the mineral hematite (or alpha iron oxide, α-Fe...

source:Technology NetworksRare-earth elements are in many everyday products, such as smart phones, LED lights and batteries. However, only a few locations have large enough deposits worth mining, resulting in global supply chain tensions. So, there's a push toward recycling them from non-traditional sources, such as waste from burning coal -- fly ash. Now, researchers in ACS' Environmental Science & Technology report a simple method for recovering these elements from coal fly ash using an ionic liquid.While rare-earth elements aren't as scarce as their name implies, major reser...

source：Global TimesThe US and its allies, which plan to spend big to counter China's dominance in rare-earth sector, seem to have encountered a bigger problem that money can't solve: an acute shortage of companies and projects.Rushing to secure domestic supplies of rare earths and to develop the capability to process them, the Pentagon and Department of Energy (DOE) have put money directly in several companies, but some in the industry said they are baffled by the investments because of recipients' links to China or lack of an established record, The Wall Street Journal reported on...

source：Mirage NewsRare earth-doped active fibers are crucial in space-based applications, such as space laser communication, laser radar, and space waste disposal. However, the space radiation environment can lead to a sharp increase in the optical loss of rare earth-doped active fibers, and a sharp decrease in the output laser slope efficiency or gain performance. Therefore, it is very important to improve the radiation-resistance property of rare earth-doped silica fiber.Recently, a research team from the Shanghai Institute of Optics and Fine Mechanics of the Chinese Academy of Sciences has ...
