Employing Surface Curvature for Spatially Resolved X‐Ray Reflectivity: Graphene Domains on Liquid Copper
Autor: Valentina Belova, Maciej Jankowski, Mehdi Saedi, Irene M. N. Groot, Gilles Renaud, Oleg V. Konovalov
Publikováno v: Advanced Materials Interfaces, Vol 10, Iss 15, Pp n/a-n/a (2023)
Abstract Here the possibility of utilizing X‐ray reflectivity for visualization with ≈µm spatial resolution of a surface with a heterogeneous electron density due to a partial coverage by another nanometrically thin material is demonstrated. It

X-ray reflectivity from curved surfaces as illustrated by a graphene layer on molten copper
Autor: Oleg V. Konovalov, Valentina Belova, Francesco La Porta, Mehdi Saedi, Irene M. N. Groot, Gilles Renaud, Irina Snigireva, Anatoly Snigirev, Maria Voevodina, Chen Shen, Andrea Sartori, Bridget M. Murphy, Maciej Jankowski
Publikováno v: Journal of Synchrotron Radiation, Vol 29, Iss 3, Pp 711-720 (2022)
The X-ray reflectivity technique can provide out-of-plane electron-density profiles of surfaces, interfaces, and thin films, with atomic resolution accuracy. While current methodologies require high surface flatness, this becomes challenging for natu

Graphene at Liquid Copper Catalysts: Atomic‐Scale Agreement of Experimental and First‐Principles Adsorption Height
Autor: Hao Gao, Valentina Belova, Francesco La Porta, Juan Santiago Cingolani, Mie Andersen, Mehdi Saedi, Oleg V. Konovalov, Maciej Jankowski, Hendrik H. Heenen, Irene M. N. Groot, Gilles Renaud, Karsten Reuter
Publikováno v: Advanced Science, Vol 9, Iss 36, Pp n/a-n/a (2022)
Abstract Liquid metal catalysts have recently attracted attention for synthesizing high‐quality 2D materials facilitated via the catalysts’ perfectly smooth surface. However, the microscopic catalytic processes occurring at the surface are still

The Effects of Cholesterol Oxidation on Erythrocyte Plasma Membranes: A Monolayer Study
Autor: Bob-Dan Lechner, Paul Smith, Beth McGill, Skye Marshall, Jemma L. Trick, Andrei P. Chumakov, Charles Peter Winlove, Oleg V. Konovalov, Christian D. Lorenz, Peter G. Petrov
Publikováno v: Membranes, Vol 12, Iss 9, p 828 (2022)
Cholesterol plays a key role in the molecular and mesoscopic organisation of lipid membranes and it is expected that changes in its molecular structure (e.g., through environmental factors such as oxidative stress) may affect adversely membrane prope

Publikováno v: Materials, Vol 13, Iss 20, p 4635 (2020)
X-ray absorption near edge structure (XANES) spectra for protein layers adsorbed at liquid interfaces in a Langmuir trough have been recorded for the first time. We studied the parkin protein (so-called E3 ubiquitin ligase), which plays an important

Growth, structure and templating of anthradithiophene and its β-methylthiolated derivative
Autor: Chengyuan Wang, Nadine Russegger, Giuliano Duva, Oleg V. Konovalov, Maciej Jankowski, Alexander Gerlach, Alexander Hinderhofer, Frank Schreiber
Publikováno v: Materials Chemistry Frontiers. 6:3422-3430
The thin film growth behaviors of ADT and β-MT-ADT are studied by X-ray diffraction techniques and atomic force microscopy, and the templating effect on the thin film growth process of β-MT-ADT is investigated with DIP as the templating layer.

Preserving the stoichiometry of triple-cation perovskites by carrier-gas-free antisolvent spraying
Autor: Oscar Telschow, Miguel Albaladejo-Siguan, Lena Merten, Alexander D. Taylor, Katelyn P. Goetz, Tim Schramm, Oleg V. Konovalov, Maciej Jankowski, Alexander Hinderhofer, Fabian Paulus, Frank Schreiber, Yana Vaynzof
Publikováno v: Journal of Materials Chemistry A. 10:19743-19749
The use of antisolvents during the fabrication of solution-processed lead halide perovskite layers is increasingly common. Usually, the antisolvent is applied by pipetting during the spin-coating process, which often irreversibly alters the compositi
