Indian researchers spot rare supermassive black hole, opens new avenues for star formation research source:downtoearthA rare supermassive black hole has been spotted by a team of Indian researchers, according to a recent study.The monster black hole is about one billion light years away from the Earth, noted the study published in the Royal Astronomical Society’s monthly notices.The black hole in question was captured, spewing a jet of radiation and particles in one direction, unlike others that fire jets in opposite directions.“But strangely for this galaxy, only one side of the jet is s...

Enhanced terrestrial Fe(II) mobilization identified through a novel mechanism of microbially driven cave formation in Fe(III)-rich rocks source:natureAbstractMost cave formation requires mass separation from a host rock in a process that operates outward from permeable pathways to create the cave void. Given the poor solubility of Fe(III) phases, such processes are insufficient to account for the significant iron formation caves (IFCs) seen in Brazilian banded iron formations (BIF) and associated rock. In this study we demonstrate that microbially-mediated reductive Fe(III) dissolution is...

source:phys.orgResearchers have devised a method for combining high-cost platinum and a low-cost rare earth element, lanthanum, as an alloy to serve as a catalyst in the next generation of fuel cells that will improve their performance and slash their cost. The development should make it easier to decarbonize those heavy transport vehicles that are less suitable to the use of batteries.The method is described in a paper appearing in Nano Research.Batteries may have won the battle against hydrogen fuel cells for cleanly powering cars, but a number of other forms of transportation find it diffic...

source:/cleantechnicaChemistry was never really my strong point, and I can’t remember seeing neodymium and praseodymium (NdPr) on the periodic table in high school, but these rare earth elements (REE) are becoming more and more important for driving the future of the electric vehicle revolution. There are several local companies mining for rare earths in Australia, and Arafura Resources looks set to become a major player with its Nolans project in the Northern Territory situated 135 kilometres north of Alice Springs.Australia’s first nations people are benefiting from the project, as a “Native...
