Settling a half century of debate, researchers have discovered that tiny linear defects can propagate through a material faster than sound waves do. These linear defects, or dislocations, are what ...

A study using EBSD and TEM imaging found that “b” dislocations in olivine occur in roughly 17% of analyzed crystals. These defects, once considered minor, may significantly influence mantle ...

Minerals form the building blocks of almost everything on Earth. They are made up of crystals—regular, repeating atomic ...

Posterior shoulder dislocation occurs when the top of the upper arm bone, known as the humerus, moves backward out of its socket. This causes pain, muscle spasms, and a limited range of motion. The ...

Illustration of an intense laser pulse hitting a diamond crystal from top right, driving elastic and plastic waves (curved lines) through the material. The laser pulse creates linear defects, known as ...

A new study led by the University of Liverpool examined olivine to better understand how it deforms. The researchers were surprised to find that about 17% of the crystals showed evidence of ...

(Nanowerk News) Settling a half century of debate, researchers have discovered that tiny linear defects can propagate through a material faster than sound waves do. Dislocations in materials can ...
