In this section we shall investigate the dynamics of particles in a medium with a screw dislocation along the z direction as shown in Fig. 1. Before going to the details, let us briefly discuss the ...

Grain boundaries (GBs) trigger structure-specific chemical segregation of solute atoms. According to the three-dimensional (3D) topology of grains, GBs - although defined as two-dimensional defects - ...

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 ...

An international team of researchers, led by University of Toronto Engineering Professor Yu Zou, is using electric fields to control the motion of material defects. This work has important ...

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 materials. So, as a ...

Material structures are rarely perfect, but researchers at the Japan Advanced Institute of Science and Technology (JAIST) have now identified a way to make them more so. By monitoring in real time how ...

Researchers have discovered that engineering one-dimensional line defects into certain materials can increase their electrical performance. Materials engineers don't like to see line defects in ...

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 ...
