We might imagine crystals to be perfect structures, but they are, in fact, often plagued with "defects." Curiously enough, such defects often appear due to atoms undergoing reorganization to lower 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 ...

Materials scientists at Rice University have developed a new workflow methodology for measuring microscopic defects in ...

A new path has opened toward manufacturing high-performance precious-metal catalysts capable of producing and utilizing ...

Dr. Edwin L. Thomas, professor in the Department of Materials Science and Engineering, and a team of researchers from Texas A&M University and Yonsei University recently discovered a helicoidal-shaped ...

Electron microscopy has become indispensable for identifying and understanding defects in engineering materials, from metallic alloys to semiconductor thin films. Conventional transmission electron ...

Today’s commercial SiC substrates are riddled with these atomic-scale imperfections, with thousands threading through each ...

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 ...

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 ...

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 ...

(Nanowerk News) Settling a half century of debate, researchers have discovered that tiny linear defects can propagate through a material faster than sound waves do. Dislocations in materials can ...
