New paper published: "Colossal Effect of Nanopore Surface Ionic Charge on the Dynamics of Confined Water"

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).

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

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!

  • 06.10.2026 Multimodal synchrotron X-ray analysis of palm-leaf manuscripts

    Combining synchrotron X-ray scattering and fluorescence with machine learning, we identified structural and compositional signatures in historical palm-leaf manuscripts that discriminate between botanical genera and reflect their processing. The non-destructive approach provides a material science basis for provenance studies, complementing codicological and historical evidence. See our publication in npj Heritage Science and the press release.

  • 17.09.2026 A Tale of Two Waters: H₂O and D₂O Electrify Surfaces Differently

    Hydrophobic nanoporous silicon acts as a single platform for comparing three solid–liquid triboelectrification regimes: immersion–emersion, droplet contact, and pressure-driven pore intrusion, with H2O and D2O highlighting isotope-dependent electrical responses. Rather than providing one simple mechanism, the study published in The Journal of Physical Chemistry C opens new questions about the molecular origins of water–solid electrification—and shows how isotope substitution can help uncover them.

  • 05.06.2026 Water, Clay and Carbon: A New Route to Sustainable Energy Storage

    🌎 Water, Clay and Carbon: A New Route to Sustainable Energy Storage - we demonstrate an all-water supercapacitor stable over 60,000 charging cycles. 

    💧⚡Can pure water store electrical energy? A research team within the Cluster of Excellence BlueMat – Water-Driven Materials has now shown that it can.

    🔋 By confining water within nanometer-sized channels in clay minerals, the team developed a supercapacitor capable of efficiently storing and transporting electrical charge with remarkable stability.
