  • Can 3D-Printed Magnets Replace Rare Earth Magnets?
    06/19/2018

    Machine Design carried a story on research at Ames Laboratory's Critical Materials Institute that used laser 3D metal printing to turn permanent magnet material into an economical alternative to more expensive rare-earth neodymium iron boron (NdFeB) magnets. The researchers experimented with magnets 3D printed from different combinations of cobalt, iron, copper, and cerium (a less-expensive, more-plentiful rare earth material than neodymium). The researchers produced a range of compositions in samples that were printed using a 3D laser metal printer.

  • Inkjet-Printed Graphene Plus Laser Yields Washable Electronics
    06/15/2018

    Electronic Design carried an article about research by Iowa State University and Ames Laboratory into the use of graphene as the basis for washable electronics. By combining graphene and sophisticated laser-based processing, they have developed circuits that are low-cost, flexible, highly conductive, and water-repellent.

  • New thermoelectric material may reduce wasted energy
    06/15/2018

    Thermoelectric materials can be used to harness heat energy into electricity and these materials are often used in space as well as capturing lost heat energy on earth. Ames Laboratory associate and Iowa State University researcher Kirill Kovnir synthesized an intermetallic clathrate, a solid compound in which one component is trapped within the crystalline framework of another.

  • Joining of Metal Based Hybrid Materials
    06/12/2018

    Ames Laboratory researchers collaborated on a project recently published in Advanced Engineering Materials that summarized the current state-of-art novel joining experimental techniques and the bonding strength by various theoretical studies. The team is looking at solving the age old problem of trying to join dissimilar materials.

  • Physicists use terahertz flashes to uncover new state of matter hidden by superconductivity
    06/04/2018

    Using the physics equivalent of the strobe photography that captures every twitch of a cheetah in full sprint, researchers have used ultrafast spectroscopy to visualize electrons interacting as a hidden state of matter in a superconductive alloy that could one day have implications for faster, heat-free, quantum computing, information storage and communication.
