Many materials lose their useful properties as soon as their dimensions fall below a certain limit. This so-called size effect, the sources of which may be quite diverse, can be a road block for the ...

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 ...

Dislocations can save lives. This stems from the fact that the one-dimensional defects in a metal play an important role when the material deforms: for example, when a car body panel crumples in an ...

AMES, Iowa – Materials engineers don’t like to see line defects in functional materials. The structural flaws along a one-dimensional line of atoms generally degrades performance of electrical ...

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 ...

The ever increasing requirements on miniaturisation and efficiency of electronic components result in efforts to incorporate new materials into silicon-based microelectronics, in order to overcome the ...
