The ICE 2 is the second series of German high-speed trains and one of six in the Intercity-Express family since 1995. The ICE 2 (half-) trains are even closer to a conventional push–pull train than the ICE 1, because each train consists of only one locomotive (Class 402, called powerhead), six passenger cars (Classes 805 to 807) and a cab car (Class 808).
To create ice XVII, the researchers first produced filled ice in a stable phase named C 0 from a mixture of hydrogen (H 2) and water (H 2 O), using temperatures from 100 to 270 K (−173 to −3 °C; −280 to 26 °F) and pressures from 360 to 700 MPa (52,000 to 102,000 psi; 3,600 to 6,900 atm), and C 2 are all stable solid phases of a mixture of H 2 and H 2 O molecules, formed at high pressures.
Aug 25, 2021 · As of 2021, there are now twenty known crystalline forms of ice (Hansen, 2021) with scientists still attempting to discover more. This results in a very complicated phase diagram of different phases of ice (Fig 1 in link). In addition to crystalline ice, there is also amorphous ice. Amorphous solids do not have a defined crystal structure ...
Half the open hexagonal channels of ice Ih have collapsed in ice II.The relationship of the ice II structure to ice Ih can be visualized by detaching the columns of hexameric ice Ih rings, moving them relatively up or down at right angles to their plane, rotating them about 30° around this axis and re-linking the hydrogen bonds in a more compact way to give a density of 1.16 g cm −3.
During an ice age, a glacial is the period of time where glacial advancement occurs. [1] Similarly, an interglacial or interglacial period is the warmer period of time between ice ages where glaciers retreat and sea levels rise. [2] Over the last 450,000 years, glacials have lasted anywhere from 70,000 to 90,000 years whereas interglacials last ...
A CAC 1 ship is capable of navigation in any ice regime found in the Canadian Arctic and unrestricted ramming of the heaviest ice features (except icebergs or similar ice formations) for the purpose of ice management. CAC 2 is seen as a commercial cargo carrying ship which can trade anywhere in the Arctic, but would take the easiest route. It ...

ce-two (Ice II)Ice-two (ice II) may be synthesized from hexagonal ice at 198 K and 300 MPa or by decompressing ice-five (ice V) at 238 K but is not easily formed by cooling ice-three (ice III) (see. Phase Diagram). It may form a major proportion of icy moons such as Jupiter's. annymede [839].Its unit cell, which forms rhombohedral crystals ...
