Research interests in our research group

The research scope of the group includes heterogeneous materials, theoretical and numerical modelling, complex fluid mechanics and rheology, X-ray tomography and 3D image analysis, as well as their applications in various industrial problems. The group runs an extensive X-ray Tomography Laboratory that includes three X-ray scanners used in non-invasive three-dimensional imaging and analysis of the internal microstructure a wide range of heterogeneous materials. The research topics of the group include also statistical characteristics of random packings of elongated particles, structural analysis related to development of new biocomposites, complex flow dynamics and transport in heterogeneousxraytomo.jpg materials.

X-ray tomography laboratory

The primary research facility within the X-ray Tomography Laboratory includes three tomographic scanners including two microtomographs and a nanotomograph. Together, these devices are capable of non-intrusive three-dimensional imaging of the internal structure of heterogeneous materials with resolution ranging from 40 μm up to 50 nm. The laboratory is equipped with comprehensive set of instruments for sample preparation and manipulation. The laboratory is also equipped with specific devices for measuring various mechanical and transport properties of materials. The entire facility has high utilization rate in basic and applied research related e.g. to development of novel organic materials, and to analysis of structural and transport properties of complex materials such as composites and bentonite clay.
