A displacement reaction occurs, wherein calcium ions (Ca2+) are replaced by iron ions (Fe3+), forming soluble rare earth metal chlorides (REM-Clx). Sodium borohydride (NaBH4) is used as a reduci[...]


Our summary: The method recovers rare earth metals from phosphogypsum waste using leaching with ferric chloride and hydrochloric acid. It achieves high recovery efficiency of 95-98% for metals like cerium and neodymium. The process is cost-effective, environmentally friendly, and scalable for industrial applications.

Abstract: We report a detailed investigation of spin relaxation dynamics in the rare-earth-doped crystal 171Yb:Y2SiO5, a promising platform for quantum memory based on atomic frequency combs. The population dynamics among the four ground-state hyperfine levels were studied in the 50 mK–6 K temperature range by optically modifying the spin populations and monitoring their return to thermal equilibrium via absorption spectroscopy. Below 1 K, population rethermalization occurs on timescales of several ho[...]


Our summary: The study investigates spin relaxation dynamics in 171Yb:Y2SiO5 single crystals for quantum memory applications. It reveals that population rethermalization occurs over hours below 1 K, influenced by spin-phonon interactions.

Abstract: The increasing demand and production of neodymium-iron-boron-based permanent magnets (NdFeB-PMs) for the electronics, energy sector, and automobile industries led to disposal consequences. The NdFeB-PMs contain a substantial amount of rare earth elements (REEs). Although China is the largest exporter of REEs to the world, it has applied some restrictive policies in terms of supply chain and taxes. To address such issues, this review systematically examines current recycling techniques, including[...]
