Minerals form the building blocks of almost everything on Earth. They are made up of crystals—regular, repeating atomic structures that fit together like a three-dimensional pattern. When minerals ...

Olivine, the most common mineral in the upper 400 km (about 250 miles) of Earth’s interior, has long been studied for how it deforms. Scientists have identified two primary directions of dislocation ...

Researchers and industries have been using transmission electron microscopy (TEM) to study semiconductors' stacking and dislocation faults. This article considers the analysis of crystal structures.

The high sensitivity of the reflection electron microscopy (REM) technique to small changes in the crystal structure and composition of the top surface layers of various crystalline materials makes it ...

(Nanowerk News) An international team of researchers, led by Professor Yu Zou (MSE), is using electric fields to control the motion of material defects. This work has important implications for ...

Researchers at the University of Illinois at Urbana-Champaign have shown for the first time that expensive aberration-corrected microscopes are no longer required to achieve record-breaking ...

Electron microscopy is a powerful technique that provides high-resolution images by focusing a beam of electrons to reveal fine structural details in biological and material specimens. 2 Because ...
