Controlled doping of electrocatalysts through engineering impurities
Se-Ho Kim, Su-Hyun Yoo, Sangyong Shin +9
Fuel cells recombine water from H2 and O2 thereby powering e.g. cars or houses with no direct carbon emission. In anion-exchange membrane fuel cells (AEMFCs), to reach high power d…
Origins of the hydrogen signal in atom probe tomography
Su-Hyun Yoo, Se-Ho Kim, Eric Woods +3
Atom Probe Tomography (APT) analysis is being actively used to provide near-atomic-scale information on the composition of complex materials in three-dimensions. In recent years, t…
Understanding alkali contamination in colloidal nanomaterials to unlock grain boundary impurity engineering
Se-Ho Kim, Su-Hyun Yoo, Poulami Chakraborty +10
Metal nano-aerogels combine a large surface area, a high structural stability, and a high catalytic activity towards a variety of chemical reactions. The performance of such nanost…
Dielectric properties of nano-confined water: a canonical thermopotentiostat approach
F. Deißenbeck, C. Freysoldt, M. Todorova +2
We introduce a novel approach to sample the canonical ensemble at constant temperature and applied electric potential. Our approach can be straightforwardly implemented into any de…
Density-functional theory study of the initial oxygen incorporation in Pd(111)
Mira Todorova, Karsten Reuter, Matthias Scheffler
Pd(111) has recently been shown to exhibit a propensity to form a sub-nanometer thin surface oxide film already well before a full monolayer coverage of adsorbed O atoms is reached…
Kinetic hindrance during the initial oxidation of Pd(100) at ambient pressures
E. Lundgren, A. Stierle, M. Todorova +7
The oxidation of the Pd(100) surface at oxygen pressures in the 10^-6 to 10^3 mbar range and temperatures up to 1000 K has been studied in-situ by surface x-ray diffraction (SXRD).…
