STEM operates by focusing a beam of electrons into a narrow probe that is scanned across a thin specimen. As the electrons interact with the sample, they are either scattered or transmitted. The ...

Definition:4D Scanning Transmission Electron Microscopy (4D-STEM) is an advanced imaging technique that combines high-resolution electron microscopy with diffraction pattern analysis over a ...

Widespread ownership of modern smartphones could make for more accessible—and equitable—microscopy in many elementary and middle school classrooms. According to University of Georgia research, iPhone ...

In many communities around the world, students’ ability and enthusiasm to pursue STEM fields in their high school and college careers is limited by a lack of resources which prevent them from ...

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.

With the demand for high-performnce materials increasing, it has become necessary to optimize their structural properties at the nanoscale, underscoring the importance of systematic and routine ...

A comparison of experimental annular dark field (ADF)-scanning transmission electron microscopy (STEM) and electron ptychography in uncorrected and aberration-corrected electron microscopes. In the ...

Researchers have developed a method for using remote-controlled, internet-connected microscopes to enable students anywhere in the world to participate in designing and carrying out biology ...
