Question

What's the difference between SEMS and a TEMS microscope

Answer 1

SEM (Scanning Electron Microscope) is used to characterized the surface morphology, particle size (Not able to measure nano size powders)

TEM used to measure nano particles size, measurement of grain size, crystallite size, atomic arrangement in material, etc.

Basically, TEM can measure and analyze much smaller particle sizes, whereas SEM looks more at the surface level and the larger groups of molecules and thus larger particles

Answer 2

oh and TEM stands for Transmission electron microscope if you weren't sure
