Functional heterophasic liquid metals

Responsive Materials, Volume 1, Issue 1, August 2023., 2023
Adding metallic elements in the pure liquid metal (LM) (that forms heterophasic LMs) not only addresses the challenges but also brings appealing features into LMs. The heterophasic LMs broadly expand the applications of LM‐based systems in soft electronics, magnetic robot, catalysis, energy management, and biomedicine. Abstract Liquid metals (LMs) have
