An electron microscope is a type of microscope that produces an electronically-magnified image of a specimen for detailed observation. The electron microscope uses a particle beam of electrons to illuminate the specimen and create a magnified image of it. The microscope has a greater resolving power than a light-powered optical microscope, because it uses electrons that have wavelengths about 100,000 times shorter than visible light (photons), and can achieve magnifications of up to 2,000,000x, whereas light microscopes are limited to 2000x magnification.

Understanding Deformation Processes in Nanocrystalline Metals Through the Use of Real-time Electron Microscopy Techniques
03 May 2007 | | Contributor(s):: Eric Stach
It is has long been known that the grain size of a material has a substantial effect on its mechanical strength, through the well-established Hall-Petch relationship. In the past decade or so, there has been a resurgence of interest in this topic resulting from the ability to create metals with...
What Can the TEM Tell You About Your Nanomaterial?
26 Feb 2007 | | Contributor(s):: Eric Stach
In this tutorial, I will present a brief overview of the ways that transmission electron microscopy can be used to characterize nanoscale materials. This tutorial will emphasize what TEM does well, as well where difficulties arise. In particular, I will discuss in an overview manner how...
