source:AZO MaterialsIn an article recently published in the open-access journal Materials, the researchers reported the development of white light-emitting diodes (WLEDs) by using rare-earth-free luminescent materials.BackgroundSolid-state lighting (SSL) sources that are based on light-emitting diodes are a new generation of energy-saving illumination solutions. In the field of solid-state lighting, developing WLEDs having a combination of high color rendering index (CRI) and good deep-red color rendering R9 is a major difficulty.The majority of WLEDs, on the other hand, rely on rare-earth ino...

source:Bicycle RetailerThe Stan's M-pulse hubs have been in development for the past two years to enhance engagement with less resistance than conventional pawl-and-ratchet hubs.What makes the M-pulse hub stand out is a locking-engagement system with six pawls equipped with Neodymium rare earth magnets. With 216 points of engagement, the hub needs only 1.66 degrees of rotation to apply torque to the rear wheel, according to Stan's.When engaged, according to Stan's, multiple teeth on each pawl lock into a hardened steel ratchet ring while each pawl's magnet ensures perfect align...

source:The West AustralianArafura Resources has a shovel-ready rare earths deposit in the Northern Territory it says could supply over 5 per cent of the world’s insatiable demand for the all-important heavy rare earth elements. The company’s Nolans rare earth project is fully approved and houses a massive 29.5 million tonnes reserve at 2.9 per cent total rare earth oxides with excellent infrastructure nearby and a supply agreement with Korea already locked away.The Nolans project sits 130 kilometres north of Alice Springs in Australia’s Northern Territory and comprises a shovel-ready neodymium...

source:Green Car CongressA team of researchers from the Critical Materials Institute (CMI), a US Department of Energy Innovation Hub led by the Ames Laboratory, developed a novel way to extract rare earth elements from the high-powered magnets in electronic waste (earlier post). Recently, TdVib LLC, a company based out of Boone, Iowa, signed a license agreement for the technology with Iowa State University Research Foundation, which handles patenting and technology transfer activities for Ames Laboratory.TdVib designs and manufactures technology-driven, high-value systems based on electromagne...
