TEM works by transmitting a beam of electrons through an ultra-thin specimen. As the electrons interact with the specimen, they are scattered or transmitted, producing an image that is magnified and ...

High-resolution electron microscopy images of the catalyst captured at the CFN. Frame A shows the catalyst with a scale bar representing 20 nanometers (nm) after three consecutive reaction cycles; B ...

Researchers developed NSYOLO, an AI framework that automatically segments and analyzes nanoparticles in electron microscopy images with high precision, improving accuracy in complex imaging ...

Cryo-transmission electron microscopy (cryo-TEM) allows us to observe samples in a preserved state that is close to their native form, making it a highly effective way to examine biological samples.

An electron microscopy image can capture atoms arranged in a crystal lattice or defects threading through a semiconductor material, but turning that image into materials insight can take weeks of ...

Support grids are a key part of electron microscopy measurements; the choice of the grid can directly influence the quality and accuracy of the final image. This is particularly true for transmission ...

Some key applications of gold nanoparticles include photonics, medicine and catalysis. 3 Gold nanoparticles have a high absorption cross-section in the visible and infrared regions, which can be tuned ...
