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...

Researchers develop photocatalyst with irregular surface characteristics to convert carbon dioxide into fuel source:Daegu Gyeongbuk Institute of Science and TechnologyA research team have developed a high-efficiency photocatalyst that converts carbon dioxide (CO2), a major contributor to climate change, into natural gas (methane, CH4). The team is led by Professor In Soo-il of the Department of Energy Science & Engineering at DGIST. The study is published in the journal Applied Catalysis B: Environment and Energy.Global warming causes abnormal climates around the world, threaten...

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 ...

source:live scienceScientists have genetically modified a tiny bacterium to rapidly purify the rare-earth metals used in computers, electric car batteries and hard drives.The new technique, described in a paper published Dec. 6 in the journal Synthetic Biology, could one day replace the environmentally harmful methods currently used to separate these elements from the metals with which they're normally found, researchers said.Rare-earth elements (REEs), or lanthanides, include the elements dysprosium, terbium and neodymium and are found on the third group and sixth row of the periodi...
