Highlights – Institute for Materials and X-Ray Physics

May 2024 - At this year's PSST conference in Brno (Czech Republic) Stella Gries received the prize for the talk of the day. Congratulations to her and also to Manfred May for the 2nd place in the best poster award of the conference!

March 2024 - Revolution through Water

A new research initiative has been launched at the TUHH with a strong involvement of our institute. See the project website here and also a research news contribution on this research project here.

22.05.2025 Cluster of Excellence "BlueMat: Water-driven materials" approved

BlueMat has been awarded funding through the Cluster of Excellence program (ExStra)!

Hamburg University of Technology (TUHH) and its partner institutions will receive funding totalling 70 million Euro. The application process was challenging: out of a total of 143 draft proposals for new clusters of excellence, only 41 were invited to submit a full proposal. In this second round, the new applications competed with the 57 already established clusters. Of a total of 98 applications submitted, only 70 were approved. The Cluster of Excellence will initially be funded for seven years until 2033.

We would like to thank all of our partners for their hard work. The whole team is energized and eager to begin bringing our vision to life. Stay tuned for updates as we embark on this exciting journey!
26.02.2025 Centre for Molecular Water Science (CMWS) inaugurated

The DESY-initiated CMWS is a Europe-wide research network in the field of molecular water research. The CMWS declaration has been signed by forty-seven founding members from twelve countries – including fourteen German universities and eight Helmholtz Centres. See also the corresponding press release.

12.09.2024 Article "Deformation dynamics of nanopores upon water imbibition" published in PNAS

Our article shows by a combination of experiments and computer simulations of water imbibition in nanopores that the competition between expansive, surface stress release at pore walls and negative, contractile Laplace pressures of nanoscale menisci lead to an unusual macroscopic behavior of the porous medium, which is generic for any liquid/nanoporous solid combination. The results allow one to quantify surface and Laplace stresses and to monitor nanoscale flow and infiltration states by relatively simple length measurements of the porous medium.
17.05.2024 - New publication: "Self-Assembly of Ionic Superdiscs in Nanopores"

Our study on discotic ionic liquid crystals has been published in ACS Nano - see also the DESY press release.
