Unlike the structures of crystalline materials, which scientists have been able to map in three dimensions since 1910, amorphous solids aren’t assembled in rigid, repetitive atomic units and ...

The atomic configurations of amorphous solids are difficult to characterize. Because they have no periodicity as found in crystalline solids, only local structures have been analyzed in detail.

Achieving the 3D atomic structure of amorphous materials came out of two important advances. The experiment was optimized to expose the radiation-sensitive sample to the lowest possible dose needed to ...

Amorphous solids, such as glass, obsidian, wax, and plastics, have no long-range repeating, or crystalline structure, to the atoms or molecules that they are made out of.

Mechanical deformation of amorphous solids can be described as consisting of an elastic part in which the stress increases linearly with strain, up to a yield point at which the solid either fractures ...

To obtain bonded structure with a low residual stress and a low attenuation for longitudinal leaky surface acoustic waves (LLSAWs), the propagation and resonance properties of an LLSAW on an amorphous ...
