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...

source:yahoonewsThe demand for Rare Earth Elements is growing as the world transitions to cleaner energy sources. Rare Earth Magnets are used in electric cars, wind turbines and other evolving technology. Regulations and environmental concerns have slowed production of magnets in the U.S. as China ramped up its manufacturing with fewer workplace standards.'We have a very high standard of ethics that we subscribe to and we maintain within our industry,' Society for Mining, Metallurgy and Exploration president Marc LeVier said.
