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.

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.

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!

23.04.2026 Lehmann Prize awarded to Patrick Huber

🏆 Congratulations to Patrick Huber on receiving the Volker Lehmann Prize for the most outstanding talk at the 2026 Porous Semiconductors Science and Technology Conference (PSST2026) in Naples, Italy.

💧 His presentation, “Nature’s Blueprint: Water-Enabled Functions in Hierarchically Porous Silicon,” showcased key research directions of the Cluster of Excellence BlueMat: Water-Driven Materials.

🏆 The Lehmann Prize honors Volker Lehmann, who—together with Leigh Canham and Ulrich Gösele - co-discovered the quantum confinement effect in silicon.
22.10.2025 Water as an energy carrier: nanoporous silicon generates electricity from friction with water

Exciting news! Our new publication in Nano Energy presents a novel way for converting mechanical energy into electricity – by harnessing water confined in nanometre-sized pores of silicon as the active working fluid (press release).
29.09.2025 Colossal Effect of Nanopore Surface Ionic Charge on the Dynamics of Confined Water

In a recent publication, we report a particularly rewarding result from a French-German collaboration linking Hamburg, Rennes, Grenoble and Paris, with key neutron scattering experiments carried out at the high-flux neutron reactor of the Institut Laue-Langevin in Grenoble, France.

We show that water behaves very differently when confined to tiny nanopores—and that surface charge makes all the difference. Adding ionic charges to pore walls dramatically slows down water motion, not just in the vicinity of the pore wall but throughout the entire pore. This long-range control goes far beyond simple wetting effects and highlights surface charge as a powerful tool for using water as a nanoscale working fluid in water-driven materials, membranes, and nanotechnologies.
09.09.2025 When symmetry breaks in tiny spaces

Nanopores unlock hidden chirality in exotic liquid crystals – with the observation now made by us within an international cooperation with Ukraine, France and Poland, they might find even wider usage in energy storage or conversion or tunable lenses (see press release).
22.05.2025 Cluster of Excellence "BlueMat: Water-driven materials" approved

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

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!
