The latest models of tabletop SEMs (TT-SEMs) feature a range of electron sources. Although a tungsten filament is used in a majority of TT-SEMs, certain models come with a Cerium Hexaboride (CeB 6) ...

Tungsten has the highest melting point of all metals, 3,422 degrees Celsius. This makes the material ideal for use at high temperatures in e.g. space rocket nozzles, heating elements of ...

When making the decision to purchase a scanning electron microscope (SEM) it’s important to choose an electron source appropriate for your application because the source has a significant impact on ...

Tungsten atoms are seen to come together in a way that is similar to an outer space ion. The finding suggests many more types of electron sharing between atoms could exist in nature. A team of ...
