Self-Assembly of Liquid Crystals in Nanoporous Solids for Adaptive Photonic Metamaterials

20.11.2019 Study on the Self-Assembly of Liquid Crystals in Nanoporous Solids for Adaptive Photonic Metamaterials published in Nanoscale.

X-ray scattering and optical polarimetry evidence in agreement with Monte Carlo computer simulations that confinement-controlled self-assembly of liquid crystals in nanopores allows for designing photonic metamaterials with adaptive birefringence. Movies illustrating 3-D reciprocal space mapping of a nanopore-confined columnar liquid crystal based on synchrotron-based X-ray scattering along with the peculiar textures found in the study can be downloaded from the TORE repository of Hamburg University of Technology. This work is dedicated to Prof. Peter S. Pershan (Harvard University), a pioneer in the field of soft-condensed-matter physics, on his 85th birthday, remembering his mentoring in synchrotron-based X-ray scattering from liquids.

  • 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.
