Polyamorphism, ie the presence of more than one amorphous state, was observed for the
first time in amorphous ice or glassy water. In addition to LDA (low-density amorphous ice), a …

Conspectus Understanding phase behavior of highly confined water, ice, amorphous ice,
and clathrate hydrates (or gas hydrates), not only enriches our view of phase transitions and …

We review the recent research on supercooled and glassy water, focusing on the possible
origins of its complex behavior. We stress the central role played by the strong directionality …

Many acronyms are used in the literature for describing different kinds of amorphous ice,
mainly because many different preparation routes and many different sample histories need …

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 …

Water can be supercooled to temperatures as low as− 92 C, the experimental crystal
homogeneous nucleation temperature TH at 2 kbar. Within the supercooled liquid phase its …

Water in the proximity of a surface (interfacial water) is abundant on the earth. It is involved
in various physical and chemical processes and crucial for biological function. Despite …

The well-known expansion of water on cooling below 277 K is one of several peculiar
properties that could signal a second critical point near 220 K and 0.1 GPa in pressure, deep …

A distinctive physical property of bulk water is its rich solid-state phase behavior, which
includes 15 crystalline (ice I–ice XIV) and at least 3 glassy forms of water, namely, low …

We investigate the downstroke transition from high-(HDA) to low-density amorphous ice
(LDA) at 140 (H2O) and 143 K (D2O). The visual observation of sudden phase separation at …
