This single layer is the precursor of the simple cubic (SC) unit cell. The lattice points are touching one another but not in the most efficient way. In other words, we are creating a lot of empty ...

The face centered cubic (FCC) unit cell begins with a totally different layer, one that is packed much more efficiently. This figure shows the basic layer that will be repeated throughout the entire ...

High-pressure experiments generated the first direct observation of plastic ice, which has qualities of both crystalline ice and liquid water.

The transition that determines the micro-structure of the alloy is a solid-state process: Austenite <-> Ferrite + Cementite Austenite is stable above 727 C and is an interstitial solid solution of ...

These results suggest that similar reactions between helium and iron may have occurred within Earth’s core shortly after its formation, trapping much of the primordial helium-3 in the material that ...

While the molecules are still locked in a rigid cubic lattice, they can rotate on the spot. This gives the substance a kind of hybrid state between a solid and a liquid. In the lab experiments ...

Silicon has the diamond cubic crystal structure with a lattice parameter of 0.543 nm. The nearest neighbor distance is 0.235 nm. The diamond cubic crystal structure has an fcc lattice with a basis of ...

Explicit evidence of the need for a magnetic consideration of the cubic PM phase of CrN can be obtained from the lattice parameter calculations. The measured room-temperature lattice spacing at ...
