      abstract     = {Nanolimes are dispersions of nanosized Ca(OH)2 particles in
                      alcohols often used for the consolidation of various types
                      of cultural heritage objects. The consolidation effect is
                      based on the transformation of Ca(OH)2 into CaCO3 phases
                      during carbonation process. The detection of microstructural
                      changes consequent to a consolidating treatment (essential
                      to evaluate its effectiveness) was approached adopting the
                      innovative combination of two advanced techniques, covering
                      a range in pore size from the nanometric to the millimetric
                      scale: small-angle neutron scattering (SANS) and synchrotron
                      X-ray micro-computed tomography (µ-CT). The changes in the
                      3D microstructure of samples of Maastricht limestone, a
                      well-known weak stone material considered as a sort of
                      ‘standard’ in cultural heritage conservation studies,
                      pure and treated with nanolime dispersions, have been
                      described in a fully non-invasive fashion, overcoming the
                      limitation of previous approaches. The application of
                      nanolime resulted to have a limited positive effect in
                      reducing the fine porosity. Its time evolution was
                      attributed to the progress of the carbonation reaction. On
                      the contrary, the treatment produced positive effects on the
                      porosity in the size range covered with µ-CT, reducing the
                      pore accessibility between 30 and 65 µm, suggesting an
                      improvement of the mechanical properties. The combined use
                      of SANS and µ-CT represents and novel methodological
                      approach in support of cultural heritage conservation
