    Titan™ ETEM Applications

    Electron microscopy can provide more than just static observations and high resolution characterization of materials. We introduce a unique transmission electron microscope, the Titan ETEM, specifically designed for 'environmental' in situ studies of dynamic processes, permitting gases to be present in the region of the specimen as well as elevated temperatures. This exciting development enables the in situ dynamic synthesis and reaction of materials in the TEM, allowing us to directly access chemical information, growth kinetics and catalytic processes, for example, using both imaging and spectroscopic techniques at ultra-high resolution. This allows a deep understanding of the mechanisms of reactions and identification of intermediate products at the nanoscale, even down to the atomic level.
