A research team from National Taiwan University has developed a new electron microscopy technique that enables sensitive ...

SEM stands for scanning electron microscope. The SEM is a microscope that uses electrons instead of light to form an image. Since their development in the early 1950's, scanning electron microscopes ...

A study in Nature Communications uses real-time liquid TEM and cryo-TEM to reveal how core–shell nanowires grow in colloidal ...

When all you’ve got is a hammer, everything looks like a nail. And when you’ve got a scanning electron microscope, everything must look like a sample that would be really, really interesting ...

Table 1: Electron wavelengths at different electron accelerating voltages (the higher the voltage, the higher the velocity of the electron). The impact on microscopy resolution is now clear. The ...

Huang and her team have shown that their approach quadruples the resolution of conventional transmission electron microscopes. Further, nearly any scanning transmission electron microscope can now ...

Using electron microscopy, much greater magnification levels and resolution can be achieved than with a light microscope because the wavelength of electrons is so much shorter than that of photons.

There are several kinds of electron microscopes, but for our purposes, we’ll look at the transmission electron microscope (TEM). The TEM is a bit like the school microscope, only built upside down.

Now, for no other reason than wanting a real challenge, the 28-year-old engineer picked the toughest DIY project he could imagine: a homemade scanning electron microscope, or SEM. “I wanted to ...
