Ruth Knibbe: Using a Scanning Electron Microscope
Materials engineer Dr Ruth Knibbe uses a scanning electron microscope (SEM) to image her own samples and samples for other scientists. Unlike a light microscope, an SEM uses a focused beam of electrons to produce images from the top surface of a sample. “So you don’t get lots of information from the bulk of your sample, it’s mostly topography that you’re getting information from,” says Knibbe, from Victoria University of Wellington.
