Шаблон:Article for deletion/dated Шаблон:Multiple issues Ferroelectric Glassy Water, or f-GW, is a hypothetical form of glassy water discovered by Fausto Martelli and Giuseppe Cassone, theoretical obtained upon exposing liquid water at ambient condition to external electric fields of extreme intensity.
Discovery of f-GW
The first proposal for f-GW has been reported in 2024 by Martelli and Cassone on a paper published in Nature Communications.[1] Cassone and Martelli performed ab initio molecular dynamics simulations in the Car-Parrinello formalism of water exposed to external electric fields of several intensities. Fields in the order of 0.10V-0.15 VÅ−1 induce a slow transition to a ferroelectric glass on timescales of hundreds of picoseconds. The external electric field orients the molecular dipoles in the direction parallel to the field, but the cooperative nature of the hydrogen bonds slows down relaxation process. As a result, the dynamics of the hydrogen bond network is the rate-determining process, which can be tracked by looking at the fluctuations of the network's topology. Martelli introduced this perspective in 2022, when looking at the emergence of hyperuniformity in glassy water[2]
