➀ Researchers at the Beckman Institute for Advanced Science and Technology discovered a new type of palladium and hydrogen-containing nanoparticle; ➁ The nanoparticle has a triclinic structure, which is the least symmetrical in crystal systems; ➂ The new method for creating the nanoparticle involves adding electrons to a solution with palladium ions and water, differing from existing research using electron beams.
