X-ray diffraction study on n-hexane in porous silicon

March 2009
Crystallization study on n-hexane in silicon nanochannels published in Physical Review Eand a study on phase transitions and molecular dynamics of spatially nanoconfined n-hexadecanol (a joint project with the research group of Rolf Pelster) published in Physical Review B.

Capillary Rise of Water in Nanopores

22.06.2009
Study on capillary rise dynamics of water in hydrophilic nanopores published in Physical Review E. A ray-tracing movie which illustrates this spontaneous imbibition process in mesoporous silica glass (monolithic Vycor) can be downloaded here. It employs the Liquid-Surface-Simulation Macro package (LSSM) for POV-Ray by Tim Nik Wenclawiak.

  • 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.
