Fast in situ electron tomography: nanoparticles under heat and light excitation — •Wiebke Albrecht — AMOLF, Science Park 104, 1098 XG Amsterdam, The Netherlands

Although standard transmission electron microscopy (TEM) makes it possible to obtain a wealth of information of static (nano)materials, an extension to measurements of dynamic structure-property relationships under realistic conditions is urgently needed. Moreover, with the emergence of nanoparticles with complex shapes, such in situ measurements need to be extended to 3D. Electron tomography (ET) allows for quantifying the 3D morphology of such nanoparticles but is inherently slow. In this talk, I will present how ET can be sped up to be compatible with in situ measurements. In addition, I will show how it can be utilized to quantify heat-induced nanoscale diffusion in single nanoparticles.
