Concrete structures like roads and bridges require nondestructive testing methods to identify interior defects without ...

The range of materials that concrete contains, such as stone, chalk, and sand, scatters normal sound waves, making clear ...

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 ...

Scientists used Lorentz transmission electron microscopy (LTEM) to visualize topological defects. They were able to do so by passing electrons and observing their deflections through a thin magnetic ...

This paper reviews the research progress of layered double hydroxide (LDH) with various types of defects and its regulation strategies in recent years. Furthermore, the relationship between the ...

The range of materials that concrete contains scatters normal sound waves, making clear imaging difficult to obtain.

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 ...
