Multi-pass transmission electron microscopy

open access: yesScientific Reports, 2017
Feynman once asked physicists to build better electron microscopes to be able to watch biology at work. While electron microscopes can now provide atomic resolution, electron beam induced specimen damage precludes high resolution imaging of sensitive ...

Improvement of structural quality of AlN layers grown on c-plane sapphire substrate by metal–organic vapor phase epitaxy using post-growth annealing with trimethylgallium

open access: yesAIP Advances, 2022
AlN layers were grown on a c-plane sapphire substrate by metal–organic vapor phase epitaxy (MOVPE) at 1350 °C. The structural quality of the grown AlN layers was drastically improved by post-growth annealing in mixed hydrogen, ammonia, and ...

Coexisting multi-states in catalytic hydrogen oxidation on rhodium

open access: yesNature 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 ...

Understanding electrochemical switchability of perovskite-type exsolution catalysts

open access: yesNature Communications, 2020
Exsolution, nanoparticle precipitation from oxide materials during reduction, offers a promising approach to heterogeneous catalysis. Here, authors examine the switching behavior between high and low activity and correlate the electro-catalytic activity ...

How the anisotropy of surface oxide formation influences the transient activity of a surface reaction

open access: yesNature Communications, 2021
Surface oxide formation under reaction conditions may change the catalytic activity of a catalyst. Here, the authors explore the effect of atomic structure of Rh surfaces on the surface oxide formation and its influence on catalytic activity in hydrogen ...
