source:phys.orgA team of material scientists led by Jiang Li from Shanghai Institute of Ceramics, Chinese Academy of Sciences, in Shanghai, China recently reported (Tb1-xYx)3Al5O12 magneto-optical ceramics with high optical quality. The optical transmittance, microstructure, Verdet constant, and thermal conductivity of (Tb1-xYx)3Al5O12 with different Y content were investigated in detail.It was found that Y2O3 can suppress the secondary phase and improve the optical quality of TAG ceramics. As optical quality occupies one of the most important parts of the practical performance of magneto-opti...

source:Trinity College DublinA collaborative team of researchers has made a cracking discovery with the potential to make a significant impact in the sustainable recovery of rare earth elements (REEs), which are in increasing demand for use in green energy technologies. The team found that humble eggshell waste could recover REES from water, offering a new, environmentally friendly method for their extraction.The researchers, from Trinity College Dublin's School of Natural Sciences, and iCRAG, the Ireland Research Centre in Applied Geosciences, have just published their findings in the jou...

Manganese sprinkled with iridium reduces need for rare metal without altering rate of green hydrogen production source:TechxploreAs the world is transitioning from a fossil fuel-based energy economy, many are betting on hydrogen to become the dominant energy currency. But producing "green" hydrogen without using fossil fuels is not yet possible on the scale we need because it requires iridium, a metal that is extremely rare.In a study published May 10 in Science, researchers led by Ryuhei Nakamura at the RIKEN Center for Sustainable Resource Science (CSRS) in Japan report ...
