Correlating atom probe tomography with X-Ray and electron spectroscopies to understand microstructure-activity relationships in electrocatalysts
Baptiste Gault, Kevin Schweinar, Siyuan Zhang +4
The search for a new energy paradigm with net-zero carbon emissions requires new technologies for energy generation and storage that are at the crossroad between engineering, chemi…
In-situ nitriding of Fe2VAl during laser surface remelting to manipulate microstructure and crystalline defects
Leonie Gomell, Shao-Pu Tsai, Moritz Roscher +5
Tailoring the physical properties of complex materials for targeted applications requires optimizing the microstructure and crystalline defects that influence electrical and therma…
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…
Microstructure manipulation by laser-surface remelting of a full-Heusler compound to enhance thermoelectric properties
Leonie Gomell, Tobias Haeger, Moritz Roscher +5
There is an increasing reckoning that the thermoelectric performance of a material is dependent on its microstructure. However, the microstructure-properties relationship often rem…
Dopant-segregation to grain boundaries controls electrical conductivity of n-type NbCo(Pt)Sn half-Heusler alloy mediating thermoelectric performance
Ting Luo, Federico Serrano-Sánchez, Hanna Bishara +12
Science-driven design of future thermoelectric materials requires a deep understanding of the fundamental relationships between microstructure and transport properties. Grain bound…
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…
