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 ...

Using a STEM-in-SEM conversion holder, we can convert a scanning electron microscope into a scanning transmission microscope.

It’s a problem that few of us will ever face, but if you ever have to calibrate your scanning electron microscope, you’ll need a resolution target with a high contrast under an electron beam. This ...

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 ...

Transmission electron microscopy (TEM) has long been the gold standard for detecting asbestos fibers in air samples drawn at construction sites. But researchers have found that a cheaper, less ...

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 ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. Electron microscopy has existed for nearly a century, but a record ...

Electron microscopy has become a vital tool in structural biology, enabling researchers to visualize biological macromolecules at near-atomic resolution. Recent advances have transformed it from a low ...

Felipe Rivera, director of the microscopy facility at BYU, stands in front of one of the university’s new transmission electron microscopes, which will allow undergraduate students to capture 3D ...
