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

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.

  • 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.
