source:eurekalertA University of Alaska Fairbanks–led research team has been awarded a $1.9 million federal grant to explore whether seaweeds are absorbing rare-earth elements near a rich deposit in Southeast Alaska.The study will focus on seaweeds in the waters near Bokan Mountain, a remote landmark on Prince of Wales Island known to contain rare-earth elements. Starting in March 2024, researchers will collect and analyze seaweed samples to determine whether significant amounts of metals that have washed into the ocean are being absorbed.“We want to see if seaweeds accumulate rare-earth eleme...

source:miningreviewAustralia’s Ionic Rare Earths Limited (Ionic), which is listed on the ASX, is expected to be in production within the next few months, albeit on a very small scale, at its Makuutu rare earths project in Uganda.As the company’s MD, TIM HARRISON, and its COO, DR TOMMIE VAN DER WALT, explained to ARTHUR TASSELL recently, the company is adopting a staged approach to development. The first stage, essentially a demonstration plant, is already under construction.While rare earths deposits are not particularly rare, Makuutu is highly unusual – at least in an African context – i...

source: Science China PressA research team led by Dr. Yingying Zhang (Department of Chemistry, Tsinghua University) devised a scheme utilizing silkworms to produce strong, tough silk through feeding them with rare earth ion-modified diets. The rare earth ions can be incorporated into silk fibroin through feeding. And the incorporated ions are capable of forming ion-dipole and cation-π interactions with silk fibroin. These interactions are promising to tune the structures of silk to enhance its mechanical performance.Spectra analysis confirmed the successful incorporation of rare earth ions int...
