Electron Microscopes
Through generous contributions from alumni and friends of Trevecca, we have acquired two scanning electron microscopes (SEM).  The first system has a cold field emission electron gun which allows it to image insulating samples at high resolution.  Trevecca students have worked with faculty to set up this SEM and create a digital imaging system to collect high-resolution digital images.  The second electron microscope has a low-vacuum mode for imaging "wet" samples, plus an Energy-Dispersive X-Ray Spectroscopy (EDS) system which can identify the elemental composition of samples.
