A team of researchers from Ulm University and the University of Nottingham have shown that liquid metal nanoparticles on graphene can host a hidden population of stationary atoms, creating a corralled supercooled liquid state that blurs the line between solid and liquid.
Using graphene as an atomically thin support and Cc/Cs-corrected high‑resolution TEM, they directly imaged platinum, palladium, and gold nanodroplets between 20 and 800 °C and distinguished fast‑moving liquid atoms from atoms pinned at graphene defects.
