Abstract The common solution for protecting p‐type semiconductors against photocorrosion in a photo‐electrochemical (PEC) cell is by applying a TiO2 over‐layer via atomic layer deposition (ALD). However, for the case of CuBi2O4 (CBO), this appr

Imaging Cu2O nanocube hollowing in solution by quantitative in situ X-ray ptychography

Autor: Lukas Grote, Martin Seyrich, Ralph Döhrmann, Sani Y. Harouna-Mayer, Federica Mancini, Emilis Kaziukenas, Irene Fernandez-Cuesta, Cecilia A. Zito, Olga Vasylieva, Felix Wittwer, Michal Odstrčzil, Natnael Mogos, Mirko Landmann, Christian G. Schroer, Dorota Koziej

Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-11 (2022)

Observing morphological changes of nanoparticles in solution requires advanced in-situ imaging methods. Here, the authors use X-ray ptychography to image the growth and hollowing of Cu2O nanocubes in 3D.

X-ray studies bridge the molecular and macro length scales during the emergence of CoO assemblies

Autor: Lukas Grote, Cecilia A. Zito, Kilian Frank, Ann-Christin Dippel, Patrick Reisbeck, Krzysztof Pitala, Kristina O. Kvashnina, Stephen Bauters, Blanka Detlefs, Oleh Ivashko, Pallavi Pandit, Matthias Rebber, Sani Y. Harouna-Mayer, Bert Nickel, Dorota Koziej

Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-12 (2021)

The understanding of nucleation and growth of nanostructures plays a key role in complex materials design. Here, the authors illustrate how X-ray in situ studies link transformation at the molecular- and macro- length scales during the emergence of c

Publikováno v: Nature communications. 13(1)

Understanding morphological changes of nanoparticles in solution is essential to tailor the functionality of devices used in energy generation and storage. However, we lack experimental methods that can visualize these processes in solution, or in el
