  • Rendering of the backside of a silvery metallic robotic hand.

    Soft robotic muscle lifts 1000x own weight

    K. Warner, Metal Tech News|Updated Nov 12, 2024

    Researchers have engineered a nanomaterial flexed by rare earth magnets that is as soft as skin but strong as steel. The studies of robotics, biomedical engineering, and wearable technology all intersect over the immensely complex task of replicating human musculature – creating materials strong enough to replace or enhance human limbs, flexible and soft enough to manipulate delicate objects or complete precise tasks in everyday life, during space exploration or on a b...

  • Hot-rolled nano neo processed rare earth permanent magnets.

    Heat-resistant neo magnet breakthrough

    K. Warner, For Metal Tech News|Updated Jul 3, 2023

    Researchers from the U.S. Department of Energy's Critical Materials Institute, led by Ames National Laboratory, have developed a "Hot-roll Nano Neo Magnet" method for manufacturing high-performance neodymium-iron-boron permanent magnets that are heat-resistant, easier, and greener to produce. Neodymium is a rare earth metal that tarnishes rapidly when exposed to air. In 1983, it was discovered that when alloyed with iron and boron, it would create a magnetic force 10 times...

  • ITER JET facility tokamak fusion power magnet Princeton University PPPL DOE

    DOE lab develops possible fusion magnet

    A.J. Roan, Metal Tech News|Updated Jul 12, 2022

    Scientists at the United States Department of Energy Princeton Plasma Physics Laboratory (PPPL) have designed a new type of magnet made from niobium and tin that could aid devices ranging from tokamaks to x-ray machines. In a recent experiment that shattered its old record, researchers at the Joint European Torus (JET) facility reported producing 59 megajoules of energy over five seconds with the holy grail of energy, fusion – more than doubling the facility's previous r...

  • University of Pittsburgh rare earth element magnets Powdermet DOE EV REE

    A rare earth magnets alternative emerges

    Shane Lasley, Metal Tech News|Updated Aug 24, 2021

    Researchers at the University of Pittsburgh Swanson School of Engineering are working with Powdermet Inc., an Ohio-based nanomaterials and advanced materials research and development company, to develop manganese-bismuth-based materials as an alternative to rare earths in permanent magnets. The motors in most electric vehicles made today contain rare earth permanent magnets, which leverage the naturally occurring strong magnetic force offered by rare earths such as neodymium o...
