Evaluation of threshold conditions for latent track formation in nanocrystalline Y2Ti2O7
Eurasian Journal of Physics and Functional Materials, 2022 We present the first report on the structural effects induced by swift xenon ions in nanocrystalline pyrochlore Y2Ti2O7 (outside the metal matrix) studied using high resolution transmission electron microscopy.

The abTEM code: transmission electron microscopy from first principles
Open Research Europe, 2021 Simulation of transmission electron microscopy (TEM) images or diffraction patterns is often required to interpret experimental data. Since nuclear cores dominate electron scattering, the scattering potential is typically described using the independent ...

Coexisting multi-states in catalytic hydrogen oxidation on rhodium
Nature Communications, 2021 Catalytic reactions may exhibit oscillations in the reaction rate even at constant external parameters. Here, the authors observe and explain the coexistence of such oscillations and the steady states of catalytic activity in H2 oxidation on differently ...

Phase imaging in scanning transmission electron microscopy using bright-field balanced divergency method [PDF]
Ultramicroscopy 245 (2023): 113665, 2023 We introduce a phase imaging mechanism for scanning transmission electron microscopy that exploits the complementary intensity changes of transmitted disks at different scattering angles. For scanning transmission electron microscopy, this method provides a straightforward, dose-efficient, and noise-robust phase imaging, from atomic resolution to ...

Visualizing quantum phenomena at complex oxide interfaces: an atomic view from scanning transmission electron microscopy [PDF]
Frontiers of Physics, 15(1), 13401 (2020), 2021 Complex oxide interfaces have been one of the central focuses in condensed matter physics and material science. Over the past decade, aberration corrected scanning transmission electron microscopy and spectroscopy has proven to be invaluable to visualize and understand the emerging quantum phenomena at an interface.

Visualizing H2O molecules reacting at TiO2 active sites with transmission electron microscopy
Science, 2020 Imaging reactive surface water Recent developments in transmission electron microscopy (TEM) have enabled imaging of single atoms, but adsorbed gas molecules have proven more challenging because of a lack of sufficient image contrast.
