Meet the Machines: Titan TEM
Our most powerful microscope in use is the Transmission Electron Microscope. It can image with subatomic resolution by shooting a beam of electrons through the sample material, for example this crystalline platinum nanoparticle of 12 nanometer in diameter (image 3).

While the TEM comes with its own limitations, this instrument enables our group to reveal in situ the morphology, roughness, and characteristics of the materials we work with.
Image 1: The Titan TEM is situated in the subbasement of the institute. A quiet room without vibrations is necessary to acquire good data at very high resolution.
Image 2: Andrew refills the liquid nitrogen of the camera to further reduce thermal vibrations.
