      abstract     = {For many applications, mesoporous titania nanostructures
                      are exposed to water or need to be backfilled via
                      infiltration with an aqueous solution, which can cause
                      deformations of the nanostructure by capillary forces. In
                      this work, the degree of deformation caused by water
                      infiltration in two types of mesoporous, nanostructured
                      titania films exposed to water vapor is com-pared. The
                      different types of nanostructured titania films are prepared
                      via a polymer template assisted sol–gel synthesis in
                      conjunction with a polymer-template removal at
                      high-temperatures under ambient conditions versus nitrogen
                      atmosphere. Information about surface and inner morphology
                      is extracted by scanning electron microscopy and grazing
                      incidence small-angle neutron scattering (GISANS)
                      measurements, respectively. Furthermore, complementary
                      information on thin film composition and porosity are probed
                      via X-ray reflectivity. The backfilling induced deformation
                      of near surface structures and structures inside the
                      mesoporous titania films is determined by GISANS before and
                      after D2O infiltration. The respective atmosphere used for
                      template removal influences the details of the titania
                      nanostructure and strongly impacts the degree of water
                      induced deformation. Drying of the films shows reversibility
                      of the deformation.},
