The low-pressure phase I of solid hydrogen ... close-packed lattice 2, transforms at pressures of about 110 GPa to the broken-symmetry phase II, in which the mean molecular orientations are ...

The smallest repeating structure of a solid is called a unit cell, which is like a brick in a wall. Unit cells combine to form a network called a crystal lattice. There are 14 types of lattices ...

Solid iodine forms ... This pressure-induced molecular dissociation was first observed in iodine at 21 GPa by powder X-ray diffraction experiments 1. The crystal structure of the monatomic ...

Applying pressure to the atoms leads to the formation of two interlinked solid lattice structures, the team says. Chemical interactions between atoms in one lattice are strong, meaning they stay ...

Now, a team has for the first time imaged a new quantum phase of electrons – a related structure called a Wigner molecular crystal. Basically, it’s the same solid electron phase, except that ...

While it is a solid at room temperatures, it still allows lithium ions to travel as quickly through its molecular structure as its liquid cousins. How and why these ions are able to do this ...
