• Meso-scale analysis of moisture transport in porous materials by means of neutron imaging

Transient moisture (vapor and liquid) in porous materials is one of my new fields of interests. Neutron imaging is a promising technique to quantify and visualize the time dependent process of moisture transport in porous media, with a vast application in analysis of drying and wetting surfaces (insulate materials, wood, break, concrete and soil) in building physics science. I have tried both cold and thermal neutron beamline facilities of Paul Scherrer Institute for transient moisture analysis in different building materials (mainly wood). Quantitative analysis of neutron radiographs at meso-scale shows the process of moisture uptake and distribution of localised moisture in different orthotropic orientations of wood is different and is driven by interaction between phenomena occurring at different time and spatial scales
