• Theoretical Chemistry, University of Ulm, 89069 Ulm, Germany 10.3762/bjnano.2.45 Abstract The accuracy of multislice high-resolution transmission electron microscopy (HRTEM) simulation can be improved by calculating the scattering potential using density functional theory (DFT) [1][2]. This approach accounts

• advantage of applying an IR furnace compared to conventional heating is the extremely high heating rate (up to 10 °C/s) and corresponding time saving. The resulting samples were investigated by powder X-ray diffraction, nitrogen physisorption, and high resolution transmission electron microscopy (HRTEM

Advanced analytical tools such as aberration-corrected high-resolution transmission electron microscopy (HRTEM) and related techniques as well as X-ray photoelectron spectroscopy (XPS) give important additional information on the atomic
