Develop a novel approach to image biologically derived soil on organic porous substrates like sponge and fabric and under dynamic conditions e.g. squeezing
High resolution X-ray micro Computed Tomography is a non-destructive technique useful in visualizing objects and obtain 3D images. Recently, the possibilities to visualize dynamic processes in 4D has gained interest. The focus of this project is to image the dynamic process of soil removal from porous organic substrates like sponge by conducting in-situ experiments using 4D-µCT. In-situ experiments using µCT will give better understanding on the structural modifications of the test sample and help in visualizing the possible relocation of soil particles upon external force. The trapped soil particles inside the porous structure of the sponge may result in the growth of bacteria and biofilm formation. The major challenge in imaging these constituents under X-ray µCT is the difficulty in establishing sufficient contrast between the porous media, aqueous solution and soil particles. A suitable contrasting agent is to be identified to enhance the contrast between these fluids. Unique laboratory equipment has to be designed and developed to simulate the squeezing process of the sponge during soil removal.
