Before and after: example of image denoising as applied to atomic resolution imaging of a gold nanoparticle. On the left is the original experimental data as captured. On the right is the same image ...

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.

Home to billions of microorganisms of many different types, the human body has about an equal number of both human and non-human cells. These pathogens mainly include harmless bacteria, which can ...

This article has been updated in January 2024. High resolution images of microscopic samples can be obtained experimentally using Scanning Electron Transmission Microscopy (STEM). It is an effective ...

Scanning electron microscopy (SEM) is an advanced analytical tool that massively outstrips the capabilities of traditional light microscopy. Using visible wavelengths of light on the 400 – 700 ...

Scanning electron microscopy (SEM) has been an important tool for forensic science since the 1970s, and it continues to find forensic applications today. The technique – capable of 100,000x ...
