Low-Dose and High-Speed In-Situ TEM with the K3 IS Camera Webinar

The versatile K3 IS direct detection camera is allowing for in-situ
characterization of material reactions with high ease-of-use and unhindered switching between low-dose and high-speed imaging. The large field of view with the K3 IS camera has enabled investigations on nanoparticle transformations and dynamics at temperature within the environmental TEM, lithiation of battery anodes, and 4D STEM strain mapping of nanowires post in-situ testing. Additionally, the low dose functionality has been paired with cryogenic imaging of beam-sensitive materials including battery electrodes/electrolytes and metal-organic frameworks. Beam-sensitive environmental imaging takes advantage of this advanced camera for real-time frame averaged viewing prior to the collection of stimulated events in the sample, where the look-back feature prevents crucial images from being lost. This webinar highlights the functionality of the K3 IS camera for in-situ and low-dose imaging of an array of reactions and materials, to showcase its versatility and user-friendly capabilities. Our work specializes in in-situ studies, where fast reactions and beam-sensitive materials will be covered in the most detail.
