In a joint effort across 4 GRK subprojects involving 10 GRK members, CENEM’s strength of combining different (scattering) probes revealed fascinating structural, chemical as well as mechanical properties of supersaturated and highly faceted Ni-Au nanoparticles equilibrated by solid-state dewetting o...

Our work entitled “Hydrogenated Anatase TiO2 Single Crystals: Defects Formation and Structural Changes as Microscopic Origin for Co-Catalyst Free Photocatalytic H2 Evolution Activity” was just published in the Journal of Materials Chemistry A (DOI: 10.1039/D1TA04809K). The photocatalytic activity t...

The paper on “Microscopic Deformation Modes and Impact of Network Anisotropy on the Mechanical and Electrical Performance of Five-fold Twinned Silver Nanowire Electrodes” by Nadine Schrenker and colleagues has been recently published in ACS Nano. Congratulations! Silver nanowire (AgNW) network...

Ni-based superalloys exhibit outstanding high-temperature mechanical properties, which makes them uniquely suitable for modern jet engines and power plants. Their superb high-temperature performance (e.g., creep strength, oxidation resistance) are to large parts governed by the elementary processes ...

Two research papers from the high-temperature group have been published recently in the Proceedings of Superalloys 2020. The principal goal of the symposium is to highlight new initiatives and future growth opportunities for superalloys that are used in gas turbine engines and related applications. ...
