A continuum of amorphous ices between low-density and high-density amorphous ice

A Eltareb, GE Lopez, N Giovambattista - Communications Chemistry, 2024 - nature.com
Amorphous ices are usually classified as belonging to low-density or high-density
amorphous ice (LDA and HDA) with densities ρ LDA≈ 0.94 g/cm3 and ρ HDA≈ 1.15− 1.17 …
