Advanced Colloidal Materials Engineering

The group deals with colloidal materials synthesis with emphasis on porous sol-gel of both, organic and inorganic origin such as resins, carbons, metal oxides and oxide/metal hybrids. Primary development efforts are targeting synthesis, characterization & numerical modelling of physical properties with the goal to advance properties and applications of porous materials with custom tailorable microstructure.
Following are our key topics:
