Crystallographic defects or irregularities (known as dislocations) are often found within crystalline materials. Two main types of dislocation exist: edge and screw type. However, dislocations found ...

A Lawrence Livermore National Laboratory scientist and collaborators have demonstrated the first-ever "defect microscope" that can track how populations of defects deep inside macroscopic materials ...

For nearly a century, scientists have understood how crystalline materials—such as metals and semiconductors—bend without breaking. Their secret lies in tiny, line-like defects called dislocations, ...

Dislocations are one-dimensional defects that occur in real crystalline solids and control their plastic deformation. The presence of dislocations permits atomic planes to slip "one atomic row at a ...

Researchers recently discovered a helicoidal-shaped defect in layered polymers, uncovering how solvents can diffuse through layers and produce color changes. Dr. Edwin L. Thomas, professor in the ...

Research offers insights into how crystal dislocations -- a common type of defect in materials -- can affect electrical and heat transport through crystals, at a microscopic, quantum mechanical level.

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 ...

This is a preview. Log in through your library . Abstract Microstructure development in an interstitial-free steel during cold rolling at low strain levels (ε ≤ 9.8%) has been investigated by using ...

Quantum engineers have spent years trying to tame the fragility of qubits, only to be thwarted by the tiniest imperfections in the materials they use. Now a new line of research flips that problem on ...
