Scanning transmission electron microscopy, or STEM, is a powerful imaging technique that enables researchers to study a material’s morphology, composition, and bonding behavior at the angstrom scale.
There’s an old joke that you can’t trust atoms — they make up everything. But until fairly recently, there was no real way to see individual atoms. You could infer things about them using X-ray ...
Visualizing the mechanism of charge transfer between two oxides. (Courtesy: W Gao, UC Irvine) Scanning transmission electron microscopy (STEM) can be used to detect electric charge density as well as ...
2D images are incapable of displaying a relationship between the 3D structure and the function of nanoscale objects. The growing need to understand the relationship between the structure and function ...
A unique laboratory at Michigan Tech captured microscopic photography of snowflakes in a demonstration of the lab's high-powered scanning electron microscope. The Applied Chemical and Morphological ...
Electron microscopy is a powerful imaging technique that utilizes a beam of accelerated electrons to visualize and analyze the structure, composition, and properties of materials at the nanoscale.
Our ability to image the subatomic realm is limited, not just by resolution, but also by speed. The constituent particles that make up – and fly free from – atoms can, in theory, move at speeds ...
