The observation of square ice in graphene questioned
Algara-Siller et al.1 reported the observation of a new phase of water—‘square ice’—sandwiched between two graphene layers at room temperature. Their key evidence consists of transmission electron microscope (TEM) images of a square lattice from small encapsulated crystals, the detection…
