Examples

  • However, scientists have found that varieties of a doped mineral called perovskite work just as well, and sometimes better, than platinum.

    Ars Technica

  • An alternative material, known as perovskite, is far less expensive than platinum and may do the job more effectively, engineers from the research arm of General Motors report in the March 26 Science.
