souece:resource-recyclingWhen the founders of Noveon decided to tackle rare earth magnet recycling, they started at the beginning of the product’s life cycle instead of the end. Chris Dunn, Noveon CEO, said he made a battery manufacturing company first, but one with “resource, material-agnostic technology that allows you to even kind of redefine a supply chain using recycling material as a feedstock to directly support the magnet manufacturing process.” Noveon’s pilot plant in Austin, Texas was built in 2016 following several years of foundational work, research and development, Dunn...

The role of Nd3+ concentration in the modulation of the thermometric performance of Stokes/anti-Stokes luminescence thermometer in NaYF4:Nd3+source:natureAbstractThe growing popularity of luminescence thermometry observed in recent years is related to the high application potential of this technique. However, in order to use such materials in a real application, it is necessary to have a thorough understanding of the processes responsible for thermal changes in the shape of the emission spectrum of luminophores. In this work, we explain how the concentration of Nd3+ dopant ions affects the cha...

source:corporateknightsFor generations, the topography of Sudbury, Ontario, has been brutally defined by towering slag heaps and vast orange-hued tailings ponds – the physical legacy of almost 140 years of nickel mining and smelting by resource giants like Inco and Falconbridge. By 1910, in fact, Sudbury’s mines were supplying 80% of the world’s nickel. But by the late 20th century, the industrial fallout – corrosive air pollution, acid rain and a legacy of seemingly intractable contamination – revealed the extraordinary environmental cost of those resource riches.Fast forward to April 2022, w...

What do you get from mixing one kilogram of dry beech wood shavings, about 50g of organic full-grain spelt flour, 25g of fine plaster (CaSO4) dust as well as 500g of beech wood–based inoculum?A research team from Austria developed the mix to produce biodegradable printed circuit boards that can be used, in simple electronic devices. The group from the Johannes Kepler University (JKU) Linz put the mix into a flat plastic box and stored it in a dark cupboard. Within weeks, a tissue made of fungal fibres, a so-called mycelium, grew in the box with a paper-like, soft, white to brownish skin.The pr...
