source:phys.orgResearchers at Columbia University have successfully synthesized the first 2D heavy fermion material. They introduce the new material, a layered intermetallic crystal composed of cerium, silicon, and iodine (CeSiI), in a research article published in Nature.Heavy fermion compounds are a class of materials with electrons that are up to 1,000 times heavier than usual. In these materials, electrons get tangled up with magnetic spins that slow them down and increase their effective mass. Such interactions are thought to play important roles in a number of enigmatic quantum phenomena...

source:phys.orgNew forms of the light-emitting materials called phosphors, with enhanced versatility relative to existing options, are being developed by researchers at the National Institute for Materials Science (NIMS) in Japan, with colleagues at Tokyo University of Science and Hokkaido University. Their work is published in the journal Science and Technology of Advanced Materials.Phosphors absorb the energy of electromagnetic radiation, including visible light and X-rays, and then release it in colors that depend on their properties. They are used in many applications, including light-emit...

source:EurekalertThe ScienceThe metals called lanthanides have valuable properties for clean energy technologies such as electric vehicles and wind turbines and for many other applications. These elements include several critical materials. In nature, lanthanides are often found mixed together. Industry must separate them to take advantage of their individual properties. But conventional approaches to this separation are time consuming and costly and generate waste. Scientists have developed an efficient new method that can be tailored to select specific lanthanides. The technique combines two...
