Imperfections of crystal structure, especially edge dislocations of an elongated nature, deeply modify basic properties of the entire material and, in consequence, drastically limit its applications.

Osaka, Japan – Crystals are known far and wide for their beauty and elegance. But even though they may appear perfect on the outside, their microstructure can be quite complicated, making them ...

Crystals may seem flawless, but deep inside they contain tiny structural imperfections that dramatically influence their strength and behavior. Researchers from The University of Osaka have used the ...

Understanding how dislocations (line defects in the crystal structure) occur when 3D-printing metals has been unclear to materials scientists. Understanding when and how dislocations form in ...

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 ...

Drexel researchers have shown that a recently discovered deformation phenomenon, called ripplocation, occurs in bulk materials when constrained during compression. Every material can bend and break.

In metal alloys, behavior at the atomic scale affects the material's properties. However, the number of possible alloys is astronomical. Scientists developed a theoretical model that allows him to ...

Defect detection requirements on the order of 10 defective parts per million (DPPM) are driving improvements in inspection tools’ resolution and throughput at foundries and OSATs. However, defects ...
