    First Tellurium solid-state energy R&D

    Shane Lasley, Metal Tech News|Updated Jun 8, 2023

    Mineral explorer sees tellurium as solid-state clean energy solution, forms company to advance new tech. Before its use in thin-film solar panels, tellurium was an obscure semi-metallic element with few commercial uses. Today, this rare metalloid is a rising star of solid-state green energy that is helping to transform sunlight and heat into electricity, as well as a secret ingredient in solid-state lithium batteries with the potential to revolutionize electric vehicles.... Full story

    Apple to use 100% recycled cobalt by 2025

    A.J. Roan, Metal Tech News|Updated Apr 26, 2023

    Tech giant is also boosting recycled rare earths, gold, and tin going into Apple products. As a technology giant at the vanguard of the green transition, Apple Inc. is accelerating its work to expand recycled materials going into its famed devices, which includes a new 2025 target to use 100% recycled cobalt in all Apple-designed batteries. Last year, the company significantly expanded its use of key recycled metals, sourcing two-thirds of all aluminum, nearly three-quarters...

    Raising rare earth recovery with yeast

    K. Warner, For Metal Tech News|Updated Apr 21, 2023

    While not quite as easy as whipping up a science experiment in the kitchen, a research group from the Osaka Metropolitan University Graduate School of Engineering has developed an inexpensive and eco-friendly way to condense various rare earth elements (REEs) from natural water sources using common, food-safe ingredients. The research group, led by Professor Masayuki Azuma and Associate Professor Yoshihiro Ojima, have successfully tested an adsorbent material using dry...

    Message in a bottle: More copper needed

    Shane Lasley, Metal Tech News|Updated Apr 19, 2023

    In a clarion call to current and future mining colleagues, IMDEX geoscience chief warns lack of copper may slow energy transition. As global governments and industries scramble to ensure there is enough lithium, graphite, cobalt, nickel, and rare earths to build the collective vision of a future where electric vehicles are charged with zero-carbon renewable energy, the geoscientists charged with discovering the mineral deposits needed to meet global demand are much more... Full story

    Graphene sets magnetoresistivity record

    A.J. Roan, Metal Tech News|Updated Apr 18, 2023

    A research team at The University of Manchester led by Nobel Prize-winning Professor Andre Geim has discovered yet another superlative capability for graphene. Materials that strongly change their resistivity under magnetic fields are highly sought for various applications. Such materials are rare, and most metals and semiconductors change their electrical resistivity only by a tiny fraction of a percent at room temperature and in practically viable magnetic fields...

    MXene spray coating makes temp control

    A.J. Roan, Metal Tech News|Updated Apr 18, 2023

    An international team of researchers led by Drexel University has found that a thin coating of MXene could enhance a material's ability to trap or shed heat. The discovery, which is tied to the 2D material's ability to regulate the passage of ambient infrared radiation, could lead to advances in thermal clothing, heating elements, and new materials for radiative heating and cooling. "This research reveals yet another facet of MXene materials' versatility," said research lead...
