Low M high density transformations in ice
We have used first-principles variable-cell-shape dynamics to investigate the compressive behavior of ice XI and ice VIII. We have observed direct reconstructions between these prototypical low and high density phases, in both directions. These transformations are not observed in practice, instead both forms amorphize under (de)compression. From this perspective, the amorphous can be viewed as ...
متن کاملAmorphous ice: stepwise formation of very-high-density amorphous ice from low-density amorphous ice at 125 K.
On compressing low-density amorphous ice (LDA) at 125 K up to 1.6 GPa, two distinct density steps accompanied by heat evolution are observable in pressure-density curves. Samples recovered to 77 K and 1 bar after the first and second steps show the x-ray diffraction pattern of high-density amorphous ice (HDA) and very HDA (VHDA), respectively. The compression of the once formed HDA takes place ...
متن کاملFormation of hexagonal and cubic ice during low-temperature growth.
From our daily life we are familiar with hexagonal ice, but at very low temperature ice can exist in a different structure--that of cubic ice. Seeking to unravel the enigmatic relationship between these two low-pressure phases, we examined their formation on a Pt(111) substrate at low temperatures with scanning tunneling microscopy and atomic force microscopy. After completion of the one-molecu...
متن کاملRoom Temperature Characteristics of Polymer-Based Low Ice Adhesion Surfaces
Ice adhesion is mainly dictated by surface properties, and water wettability is frequently correlated with ice adhesion strength. However, these established correlations are limited to high ice adhesion and become invalid when the ice adhesion strength is low. Here we carried out an experimental study to explore the relationships between low ice adhesion strength and room temperature surface pr...
